Chapter 14: If No Darkness, No Light (Part 2)

_o0o_

Gunshots rang through the air as the many masked assailants opened fire on everybody in the church. Barry zipped through the room, catching every bullet fired as he went, and would continue to do so until the bad guys stopped to reload.

Seeing as their speedster had defense under control, Felicity, Wells, Lena and all the other heroes without powers acted quickly and began ushering the innocent civilians out of the line of fire. The heroes with powers, or the ones who were smart enough to have their weapons on them, decided to go on the offensive. Martin and Jacks shared a look before clasping hands and merging into one person. With a burst of flames, the red and orange clad form of Firestorm rose into the air and began hurling fireballs. Taking cover behind a pillar, Oliver pulled out his bow and started taking aim. Alex and Sara simultaneously ripped slits in their dresses for more movement.

The two of them shared a quick look of commiseration at their like-minded thinking, before they both went after the nearest goose-stepping stooge.

"Now this is how you throw a party." Mick shouted at the room. He had been quietly snoring until the gunshots rang out. Now he was totally awake and gleefully pointing his heat gun at whatever target he could find.

Kara shot off the ground at the enemy Kryptonian and the two collided in mid-air. They punched a hole in the roof of the church as their grappling with carried them out into the open skyline.

Cisco fired Vibe blasts at a few goons before crouching behind a pew next to Caitlin.

As for Dr. Snow, she was torn. She didn't want to fight because that would mean letting Killer Frost take the reins. Which worried her greatly. Not only because she didn't trust Killer Frost not to live up to her name, but also because every time they switched, she feared something would happen that would keep them from switching back.

They had yet to find any evidence that was even possible, but it didn't stop her from worrying about it. She didn't like the idea of being a permanent prisoner in her own body while an ice wielding meta-human ran loose. But she didn't want to leave because as a doctor she could still be of use here. Though so far, she hadn't mustered the courage to climb out from her hiding place.

Cisco made the decision for her. "I think it's time we introduced these guys to your mean roommate."

Caitlin gave him a dubious look before conceding. There would be plenty of call for her medical skills after the fight was over. For now, they needed Frost more. Her mind made up, she let go of her control. Her eyes flashed blue as her hair turned white. Killer Frost looked down at herself before she sneered. "Where does she find these clothes?" she asked nobody, before standing up and firing cold blasts.

Mick saw this and was immediately reminded of his old partner Captain Cold. "Now that's what I'm talking about." He roared before getting back to lighting Nazis on fire with renewed vigor.

While all of this was happening, Sara and Alex were tag teaming every Nazi that got near them. They were beating a bloody path through the church and frankly having the time of their lives doing it.

Lena was busy trying to escort the last of the civilians out when a shout from behind got her attention. She turned to find one of the soldiers pointing an automatic weapon at her and shouting orders. Fortunately, she spoke German.

"Kapitulieren oder sterben."

Knowing she was screwed if he opened fire, she knew she had to lure him closer. Toward that end, Lena put on her best 'innocent' face. "Bitte verletzt mich nicht. Ich werde alles tun, was Sie wollen."

The soldier lowered his weapon as he stepped closer. "Irgendetwas?" His tone made it clear what he was thinking as his eyes swept up and down Lena's form.

Lena chose that moment to thrust her palm up into his mask, right where his nose would be. Stunned from the strike, the soldier didn't even see it coming when Lena's knee shot up and bulls eyed right between his legs. Bent over, clutching what was left of the family jewels, he was an easy target for Lena to bring her elbow down on the back of his head. Putting him out of his misery.

With her would be assailant unconscious and no other innocent bystanders left, she reached down to relieve him of his weapon. With the usual blank look that showed she had pressed pause on her emotions, Lena pulled back on the bolt before taking one last look at her attacker.

"Nazi-Schwein."

The whole church was in utter chaos as World War III was kicked off in their city. It didn't matter to Sara or Alex. Their side was winning. It didn't matter how many foot-soldiers came their way, they were knocking them down left right and center. These grunts just couldn't compete with fighters on their level. As evidenced by Alex punching one in the face as Sara swept his legs out from under him. He fell ass over teakettle, and he wasn't getting up. The two women smiled at each other in congratulations at a job well done.

That was the moment a new opponent stepped toward them.

This one was different. Not just the uniform or the fact he carried a sword instead of a gun. But the way he carried himself. The way he moved and watched them as they fought, analyzing their movements. This wasn't some grunt that had been handed a weapon and pointed towards the battle. Knowing they would have to up their game to fight this guy, Sara looked around for something that could be used as an effective weapon. Spotting an incense burner that had been sent flying in the chaos, she grabbed it by the chain. Lifting it up, she smirked at the new guy, then started twirling it around before she swung it at him.

Oliver had spent the last ten minutes trying to cover the people trying to escape. The Nazi's had an archer of their own who had taken position on the second floor and had been sniping at any vulnerable targets he could see. Oliver had been shooting his arrows out of the air but couldn't keep doing that. He might have had the foresight to bring his bow in case of an emergency, but he wasn't on the streets of Starling City. He was in a church in Central City. Wearing not green leather and Kevlar, but a tuxedo. He could only conceal so many arrows in this situation, and his supply was running low.

He fired another arrow that split the shaft of a black arrow headed for Wells. If he kept up this shot for shot situation, the black archer was going to kill somebody eventually. He needed to take that other archer out. But he couldn't do it from here.

Spotting Cisco firing a vibe blast from the alter, Oliver had an idea. "CISCO," he hollered across all the noise of fighting and gunfire. When Cisco met his eyes, he pointed at the enemy archer. "I need a breach up top."

Cisco nodded before aiming his fist at Oliver, and a breach opened in front of him. Oliver didn't hesitate. He drew an arrow, loaded it and jumped through. He came out nearly on top of the other archer and fired at him.

'His reflexes are impressive', Oliver noted as he watched him bat the arrow aside with his bow with only a few feet of space between them. Further assessments were forgotten as they began to trade attacks. He ducked under Oliver's kick. Oliver deflected his punch. They swung their respective bows at each other and deadlocked. That was the moment the black archer did something that Oliver didn't expect.

He locked his fingers around Oliver's wrist and spun the two of them around. Before Oliver could regain his footing, he was forced back until he hit the balcony railing. This was bad. If he didn't think of something fast, he was going to drop twenty feet.

At that moment, Oliver felt something pass within inches of his head and collide with the other archer's shoulder hard enough to send him spinning away from Oliver. Oliver grimaced at the sight of a crushed metal slug embedded in the archer's armor. He knew from personal experience that armor or no armor, getting hit with a piece of metal traveling six thousand feet per second hurt like a bitch.

While his opponent was still reeling, Oliver chanced a glance over his shoulder to see where the shot had come from. Taking cover behind the pillar he had previously been crouched behind was Lena Luthor, pointing a rifle she must have taken off one of the enemy soldiers right at him.

Or rather, right in front of him. She was a pretty good shot.

He gave her a nod of thanks and watched her nod back in acknowledgement before turning back to his opponent. He watched as he pulled the bullet loose from his armor with a grunt before looking back at Oliver. The Dark Archer roared in outrage, and the two of them were trading strikes again.

Seeing Oliver go back to fighting the other archer, Lena turned her eyes towards the rest of the heroes to see how they were fairing. The whole situation was getting out of hand. There was a massive hole in the roof, several pillars had collapsed and that was just what was happening to this building.

'God only knows what's happen with Kara outside. If this goes on much longer the whole church is going to come down on our heads. We need to stop this', Lena thought as she tried to come up with anything that could force the Nazi's to retreat.

Lena's eyes landed on the engineer from Team Flash in the crowd. She couldn't recall his name. Something like Ramos? Whatever his name is, the idiot had chosen to stand in the very middle of the room and fire what looked like vibrational blasts at any bad guy he could see. Sooner or later, a Nazi was going to see him before he saw them. And that was if a stray shot didn't kill him first.

Lena didn't hesitate. She started running and leapt into the air and tackled Ramos so they both landed right between two pews. Decent cover for the moment.

"Ooow, what the hell woman?" He questioned as he rolled over to look at who had football tackled him.

"I should be asking you that. What kind of idiot stands right in the middle of every line of fir-"

CRASH

Cisco and Lena both put their hands over their heads as wood, stone and glass came falling on their heads. Luckily, only small pieces landed on them. The alter wasn't so fortunate. Looking under the pew, towards the end of the aisle, Lena could see that Kara had come crashing back in and was trying to pick herself up off the cratered floor. She was just getting to her knees when the other Kryptonian came floating in from outside.

"Stay down." The distorted voice commanded. Lena caught a glimpse of the look on Kara's face and ducked her head down again.

Just in time too, as Kara swung around to face her opponent and with all the super strength she had, slammed her hands together in a superpowered clap. The resulting sonic boom shattered every remaining window, knocked over the pews in the first few rows, and propelled the other Kryptonian up till she collided with what remained of the church roof. Only to fall back to the ground at Kara's feet.

Kara half stumbled towards the black clad Kryptonian. But Kara's grip was strong as she grabbed the masked Kryptonian by the back of her collar, and her arm was steady as she lifted her to her feet. Kara held nothing back as she delivered a punishing blow, to her opponents' gut that sent her flying to the far end of the church.

The other Kryptonian was knocked out as soon as she hit the ground. With her lying in a heap on the floor of the church, the tide seemed to have turned in their favor. With Kara in this fight, and their alien out of it, this would be over in minutes. Sadly, their leader seemed to realize this as well. He threw the downed woman over his shoulder and shouted "RETREAT," before throwing something on the ground that ignited into a light so bright, everyone had to look away and shield their eyes. A few seconds later, when the light died down and everyone had managed to clear the spots from their eyes, they looked around and found nothing.

The church was completely clear of Nazi's. They had managed to escape as quickly and quietly as they had arrived.

Everybody left standing in the church looked around assessing what had just happened. There were bullet holes in the walls, several pews were destroyed, every stained-glass window was shattered and there was two giant holes in the ceiling. Eventually, all eyes landed on the sole remaining figure at the feet of Sara and Alex.

Cisco summed up the thoughts on everyone's minds. "Who the hell invited those guys?"

_o0o_

An hour later, they were back at Star Labs trying to piece together exactly what had happened earlier. Sara and Alex had locked the Nazi dressed like Prometheus in the pipeline while Kara went in search of his comrades. And Mick made sure that the events of the day were erased from the memories of all the guests.

Caitlin, as the most experienced MD among the various teams of superheroes, had given everybody a once over. Bumps and bruises mostly, although Lena and Cisco had a few lacerations from being so close to the roof collapse. But they were all fine. And they all wanted answers.

Especially Iris as she sat, still in her wedding dress. Barry stood next to her and offered what little support he could, but he looked just as dejected as she did. Both were trying to shake off the feeling that some higher power had sent Nazis to ruin their wedding. Which was why they were happy to see Mick and Kara walk through the door to the Cortex. Now that they were all present, they could begin to figure this out.

"Did you erase everyone's memories?" Oliver asked. Ever the man to take charge during a crisis.

Mick held up a Time Bureau memory device. "Yup. Everyone's secret identities are safe and sound."

That out of the way, Barry turned to regard Kara. "Do you have any idea where they fled?"

They were all disappointed when she shrugged her shoulders. "No idea. I flew over the entire city. Not a trace of them."

"Well clearly they attacked because you all were there." Iris suggested.

Barry was quick to jump on his wife's… correction his still fiancée's train of thought. "Eliminate Earth's heroes. Then what?"

"If I remember my history: ethnic cleansing and world domination." Felicity threw out with a noticeable tremor in her voice. Oliver just pulled her closer to his side. He knew how close to home this situation had to hit her, being a brilliant and proud Jewish woman.

Jax, as the only black man in the room at present, offered up his two cents. "Yeah, make America Aryan again."

"Which it never was." Caitlin said, and Iris followed with a halfhearted, "#Melting Pot."

Not one to be left out, Mick growled, "I hate Nazis." Nobody even twitched at the appropriate, if unhelpful contribution. It was a well-known fact. Water was wet, the sun set in the west and Mick hates Nazis.

More helpful was Dr. Stein's query, "Their appearance seems like a severe course of action, given that their cause was defeated over seventy years ago?"

"What does that matter?" Lena of all people stepped forward, interrupting everybody's train of thought. "What does it matter how they got here? The point is that they're here, they're obviously well-armed and gunning for all of you. We can figure out how and where they came from after we lock them all up next to their friend."

Kara shook her head at her friends' words. "Lena, I agree with you. But it's not going to be that simple. That woman was as powerful as I am."

This time Oliver stepped forward. "That archer matched me. Shot for shot. And I think it's time we got some answers." They all looked at the monitor that showed their prisoner.

Jax was of the same opinion as Oliver but saw a problem with that. "Yeah, but he ain't talkin."

"Too bad we don't have some Veritaserum on hand." Lena spoke to the mild amusement of those present.

"Good to know that some things are multi-universal. But seriously." Cisco deflected. Alex and Kara shared matching looks with Lena. They understood what she was really saying. That she wished Harry was with them right now. And surprisingly, they both agreed. They could certainly use the help.

"We'll have to do this the hard way." Oliver said before turning and leaving the Cortex. Most of them shuddered at Oliver's words. They dreaded what it meant when Oliver talked about doing things the hard way.

Most of them decided to follow him down to the pipeline. As Kara and Lena trailed behind the crowd going to interrogate their prisoner, Lena leaned in close to Kara.

"Why did things get so tense all of a sudden?"

Kara bit her lip and hummed to herself for a moment. Wondering how to explain Oliver to Lena. "Oliver was stranded on a deserted island for five years. When he was eventually found and brought home, he started wearing a green hood and hunting criminals with a bow and arrow." She paused for a moment, wondering if she had any right to elaborate further. "Obviously, he has a more… extreme way of doing things than the other heroes on this Earth."

Lena raised her eyebrows at the mention of being trapped on an island for years. She witnessed firsthand at the church Oliver's skills with a bow. But she was a little skeptical at the 'extreme' comment. She had trouble believe someone, a non-alien, using a weapon as antiquated as a bow can be that extreme. No matter how skilled they are.

Kara chuckles to herself. She knows she is underselling Oliver. But they have other things to worry about at the moment. Lena would probably see for herself exactly how intense Oliver could be before this was over.

Standing in the pipeline, Oliver stares at the man dressed like Prometheus as everybody who followed him down gathered around.

It didn't take any prompting. No threats or posturing. He didn't even say a word before the mask is coming off. Oliver's eyes widen and he barely manages to keep his jaw from dropping at the sight of dark hair and blue eyes on a very familiar face. And he knows that he's not the only one blindsided by this. Sara and Felicity surely recognize the face of their dead friend.

"Tommy Merlyn?" Felicity asks in astonishment.

"Who's Tommy Merlyn?" Barry asks from somewhere behind Oliver. He had no intention of taking his eyes of the man in the cell. Oliver refused to even blink, too afraid that the image in front of him would vanish and he would lose his friend all over again.

"He died over four years ago." Felicity answered breathy voice.

"Oliver who is Tommy Merlyn?" Barry asked again, more insistently.

"Thea's other brother. And my best friend." Oliver said as he stepped closer to the glass.

"We're gonna need a moment alone." Oliver spoke to nobody in particular. Quick glances were exchanged behind Oliver's back before they all made for the exit.

"Well, that was a waste of time." Lena remarked, a bitter edge present in her voice. Nobody said anything to disagree with her. They had all followed Oliver down here to get some answers out of their prisoner only to be sent out of the room almost as soon as they had arrived.

"Please tell me you guys have got something." Iris, who had taken the opportunity to change out of her wedding dress, asked as soon as they made it back to the Cortex.

"We've been trying to figure out how these guys showed up in Central City more than seventy years after the end of WWII. So far, we got nothin." Cisco's dejected tone was plain for all to hear. Sara however was a little more constructive.

"I might know. Lately we've been dealing with anachronisms. Objects and people who have been displaced from their own point in time to a different point. Maybe that's what these guys are?"

Sara's suggestion did make sense (as much as time travel ever made sense), but Stein shook his head before he squashed that theory. "I don't believe so. Nazis from the 1940's who suddenly found themselves in the twenty-first century would go after the military and government installations. Why would they attack a wedding? It also wouldn't explain their modern weapons and uniforms."

"And if they were merely displaced in time, that wouldn't explain how they have a Kryptonian on their side either," Lena added as Alex nodded along with her words.

Agreeing with their reasoning, Caitlin offered another alternative. "Okay, so maybe they aren't from another time, but from another Earth."

"There's more than one?" Jax asked in amazement. And none of them blamed him for being a little overwhelmed. Time travel was hard enough to wrap your head around.

"Actually, there are fifty-two different Earths." Barry tried to answer but was interrupted by Lena.

"I can guarantee you that there are a lot more than fifty-two different Earths." She knew (in theory) that the multiverse should be composed of many different Earths, all with their own people and possibilities. The fact that she, Kara and Alex were all standing here confirmed that for her. And even if that theory was wrong and there was only a limited number of Earths out there, she knew that there had to be more than fifty-two. Harry proved that when he told her his favorite Earth had been Earth-1383.

That was way more than fifty-two.

Stein nodded at Lena. "Another Earth in the multiverse is a distinct possibility. Though I am stymied to think of a world where Nazis are in ascendency."

"I can." A raspy voice spoke from behind Stein. They all turned to see Harrison Wells leaning on the doorjamb to the medical bay. He had been so silent up to this point that most of them had forgotten he was even in the room. "There is a fifty third Earth." Wells confirmed before continuing. "A place so horrible no sane person would ever travel there. For that reason, it has no designation. It is simply called Earth-X."

'Well, that doesn't sound ominous at all,' Most of them thought as Wells finished speaking.

"Let me venture a guess." Stein began as the silence dragged on. "The Nazis developed the atomic bomb before the United States, were more than happy to use it, and won the war." Stein's straight back and stiff shoulders showed he was doing all he could to remain composed. But the sliver of disgust in the tone of his words revealed just how sickening he found the very thought of such a world.

"London, New York, San Francisco were all obliterated. The Allies surrendered and the Nazis spread across the globe like a plague. They set up outposts not only across Europe, but across the world. And aided by presidents and prime ministers sympathetic to his cause, Adolf Hitler remained the leader of the Third Reich until his death… in 1994," Wells finished with an overburdened air. As if just telling them this information was physically taxing.

"This is making me physically sick." Felicity quietly muttered as she tightened her arms around herself. But they all heard her words. Frankly, many of them were right there with her. If they lived on that Earth, Felicity and Stein would likely be living in a concentration camp simply for being Jewish. Sara would probably be right there with them, given her sexual orientation. For being black, Iris and Jax likely never would have been born at all.

"And they're not content to rule just one Earth anymore. They are trying to expand their power so that they can rule all Earths," Lena continued for her. Her own stomach tied in knots thinking what Lex would do if he lived on an Earth like that.

Kara didn't hear that last comment though. She was too lost in her own thoughts. Her mind pulled back to… something from weeks ago. Something she had dismissed at the time and had intentionally put out of her mind. She tried to recall the image of her and Alex standing inside Harry's vault and looking at some of the things that he had on display in there.

Inside a glass case, were so many things ranging from museum quality treasures to little knick-knack objects. But out of all the things they had seen, one object stood out in her memory. Inside a glass display case rested a damaged laptop with a swastika stamped on it. This led Kara to one inevitable conclusion.

"I think we know someone who's been there." Kara's eyes swept around to look at the faces of everybody present.

"We do?/You do?" Alex and Lena spoke at the same time. Kara raised her eyebrows at them and nodded her head. Not saying anything because it should have been obvious who she was thinking of.

Both of their eyes widened at the same time, but Alex spoke first. "You think he…" she trailed off as Kara nodded her head. "I do."

"Wait. He told you he had been to this… nightmarish Earth?" Lena tried to clarify. Given their animosity towards each other, she didn't see Harry sharing a story like that with Kara. At least, not willingly.

Kara turned to face Lena and shook her head in the negative. "No, he didn't tell me that. But when we were in his vault, I saw a laptop that had a Nazi swastika on it. Where else would he have gotten something like that?"

"You've been in his vault?" Lena asked, crossing her arms defensively over her chest. Harry had told her about the vault but hadn't gotten to show it to her. One of many things she regretted about the situation with Harry. Lena hated that she had had so little time with him. Precious little time with the brother she never knew she wanted until he had been standing right in front of her. Only to lose him shortly after finding him.

And apparently Kara, somebody he had a very combative relationship with, had the privilege of seeing something he never had the chance to share with his own sister. She couldn't believe it, but she was jealous, hurt and more than a little angry. And unfortunately, Kara was the only target for her feelings now.

A wide-eyed Kara leaned backwards and took a small step away from her. Shocked by the sudden aggression directed at her. Just as surprised as her sister, Alex held Kara by her shoulders and gently pulled her a few more inches away from Lena. Neither of them understood why Lena was suddenly so angry.

Barry was a welcome distraction as he asked the question that everybody not from Earth-38 had been wondering. "What are you guys talking about? Who do you know that you think has been to this Earth?"

"And what's this vault you're talkin about?" Mick growled. Several of them rolled their eyes at his newfound attentiveness. Of course, all he bothered to hear out of that was the word vault and promptly images of stuff he could steal popped into his brain.

With Kara still distracted by the glare Lena was leveling at her, Alex answered for them. "A couple of months ago, a speedster showed up on our Earth during an alien invasion."

"Yeah, your buddy Winn contacted us about him." Cisco injected in the conversation before Caitlin jumped over him.

"He asked for all of the data we had collected on speedsters. And not just how fast they could go, but their physiology, their dietary requirements, schematics on any pieces of tech we had designed to monitor them and our list of speedsters we had encountered. We gave him everything we had, but we had never encountered a speedster who called himself Paladin."

"Meh." Cisco made a sound of dissatisfaction at the name. The Earth-38 residents watched with confusion as every Earth-1 resident rolled their eyes at him this time. All of them were familiar with Cisco's almost fanatical love of naming the heroes and villains they encountered.

Iris steered them all back to the issue at hand. "Do you think this Paladin can help us? Should we send a message to your Earth and ask him to come?"

Kara and Lena finally broke their staring contest and turned to face her. "No. He already moved on from our Earth. We don't have any way of contacting him."

"Moved on from your Earth?" Sara questioned, confused like all of them by that statement.

Lena didn't want to talk about Harry anymore. She wanted to put an end to this topic. "It doesn't matter. The point is he can't help us. So, what are we going to do now?"

The room was silent for a moment as everyone contemplated different answers to that question.

"I'm going to call our team in Star City. Share with them what we've got and get them working on the problem too. Who knows? If these Nazi's are targeting Earths heroes, then maybe they sent some people there. They'll need a heads up." Felicity informed them as she grabbed her tablet and walked out of the Cortex to make her call in private.

"We'll check security cameras around the city. If those Nazi's climb out of their holes, we'll spot them," Iris informed the room from her place behind the computer console. Barry nodded his head from his place next to her.

"We gathered everything those guys left behind at the church. I'm gonna see if I can vibe anything off their stuff that might give us a location," Cisco informed them before heading for his lab.

Before he could reach the door, Wells spoke. "I'll go with you and see if they left any forensic signs of where they are holed up."

"Right behind you." Stein said before he moved to follow them out the door, Jefferson a second behind him.

Lena didn't know what Kara or Alex were going to do, but she didn't think it mattered. She was too busy trying to come up with something she could do to be useful but was drawing a blank. This wasn't her Earth. She didn't run a multi-billion-dollar company here. She had no resources, no contacts. She considered offering her computer skills, but one look at the foreign system told her the set up would only slow her down. I could offer to give their systems an L-Corp upgrade.

That was a good thought for after the current situation was resolved. But for now, there really wasn't anything she could do to be useful.

She was saved from her feelings of uselessness by an unexpected source. "Lena, I could use your help in my lab if you have time?"

Lena turned to stare at Dr. Caitlin Snow for a moment. The invitation was completely unexpected. She just nodded her head and followed her to the medical facility. She waited until they were alone to broach the subject.

"What exactly can I help you with?" Lena prompted the physician.

Dr. Snow bit her lip and shrugged her shoulders before responding. "Honestly, nothing. You just looked a little out of place and I figured you could do with an excuse to get out of there."

Lena's short spike in temper had abated when Kara left the room. But Dr. Snow's words caused it to rise again. "Out of place?" She tried not to show it, but she was a little offended that Dr. Snow didn't think Lena belonged in a room full of heroes. She thought she had been making great strides in befriending Kara's other friends.

Dr. Snow seemed oblivious to her ire. "Yeah, I know what it can feel like. Having to watch everybody else go out and fight the bad guys while you're stuck waiting for something you can do. As a physician, I'm not always helpful until somebody gets hurt. Only contributing after the fact, it can make you feel a little powerless."

Lena tried to keep her face blank as she experienced an 'aha' moment. She wasn't saying Lena didn't belong, she had merely picked up on Lena's uncertainty. But something she said made Lena curious. "You didn't seem that powerless at the church when you were using that ice sword to carve up those soldiers."

Now the ice wielder looked uncomfortable. She hesitated before opening her mouth. "That wasn't me. That was Frost. She comes out whenever I'm angry or frightened. She's the one with the ice powers."

Her words sparked Lena's curiosity. Possibilities from the physical to the psychological that could cause a person's meta-human powers to result in a split personality where only one personality could use their abilities. She decided to shelve those thoughts for later when Caitlin continued speaking.

"In fact, it wasn't until a recent incident involving a meta-human mob boss called Amunet that I started to feel like I was really a part of team Flash."

It may have been a bit selfish, but Lena found that comforting. Somebody who had been on a team of superheroes from the beginning had taken a while to feel like part of the team. "Care to elaborate on that incident?"

Caitlin bit her lip before shaking her head. "I'd rather not go into detail. No offense." She rushed to say, not wanting to be impolite. Lena nodded to let her know no offence was taken.

"Is there something you would like to talk about?" Caitlin wheedled. Lena tilted her head in confusion, unsure how to respond. "It's just, you guys have been perfectly friendly since you arrived. But a minute ago, I couldn't help but pick up on some tension between you and Kara."

Lena clamped down on her own tongue to stop her first response, which was to say there was no tension between her and Kara. That everything between them was fine. But she doubted it would have the effect she hoped it would.

She was getting a sinking feeling this was why Caitlin really brought her in here.

"It's not tension. Its… a conversation that we've both put off for too long." Lena reluctantly admitted. And she thought Caitlin believed her as she nodded her head, dropping the subject.

With nothing left to say, Lena decided to put an end to this conversation. "Well, I believe we've been in here long enough that the crowd should have dispersed. I think I'll go find Felicity and see if she has finished her phone call." She turned and moved towards the door. Before she stepped through, she decided that wasn't how she wanted to leave this discussion, she turned back to face the MD.

"Dr. Snow?" Caitlin looked at her expectantly. "Thank you, for your concern. I really do appreciate it."

Caitlin smiled at her honesty. "You know, you can call me Caitlin. We've attended a wedding and fought Nazi's together. I think we can be on a first name basis."

Lena genuinely smiled back. "I agree. But this boys club of superheroes needs every brilliant female mind they can get. You should remind them of your credentials more often." Lena's last glimpse before she left the room in search of the blonde computer genius was of Caitlin shaking her head as she giggled at Lena's words.

'I was right. I am making friends here.' Lena held her head a little higher as she walked down the curved hallway in search of Felicity. She didn't know the facility very well, but Lena didn't think the blonde would go too far to find the privacy to make a phone call. Her belief was proven right when she heard voices from the next door she came upon.

"Felicity? Are you- oh I'm so sorry!" Lena cut herself off abruptly. She was regretting coming to find Felicity now as she had walked in on what was clearly not a phone conversation, but a moment between her and Oliver. A heavy moment apparently by the way they had been leaning on each other when she walked in.

"Oh, Lena. Hi. Yeah, we were just… uh. What did you need?" Felicity awkwardly spoke. She and Oliver both rose quickly to their feet as they turned to face her. Lena felt bad for making them uneasy and ruining whatever she had walked in on. As uncomfortable as she was, she decided to take her cue from Felicity and pretend nothing had happened.

"I came to see if you had finished your phone call. I thought we could put our heads together and try to track these goose-stepping morons." Lena tried, she really tried, to lighten the mood. But her ability to put others at ease wasn't quite up to Kara's level. She was better at intimidation.

"I'll go grab the others and meet you in the Cortex. That was what you called the central laboratory: The Cortex?" She encouraged, wanting to leave the couple to do, whatever they were doing before she walked in.

"Yeah, we'll see you there." Felicity said sounding slightly annoyed. Clearly trying to politely tell Lena she could go while Oliver stood so close that he was practically wrapped around her. He stayed stoically silent from the moment she entered the room.

Honestly, this guy is a bigger brooder than Harry. Lena thinks in disbelief as she exited the uncomfortable atmosphere to find where the other geniuses had gone. Of course, the thought of her missing brother soured her mood again. I guess it's going to take some time to come to terms with him leaving.

It didn't take her long to locate them. Star Labs may have been a large facility, but most of it was taken up by the particle accelerator. It really didn't take more than a few minutes to locate the lab where Cisco, Wells and Stein had secluded themselves in their search for answers. Her search was made easier by the loud voices of Cisco and Wells arguing with each other.

"You think you can do this better than me, give it a shot."

"I have no doubt that if I had your powers, I would be ten times better at this than you. Seeing as how you haven't gotten any results at all."

"And what exactly has your forensic analysis turned up that's useful. Oh, that's right, nothing."

This was the scene that greeted Lena as she came around the corner. She wasn't the least bit surprised by the sight of Wells and Cisco standing in the middle of the room, seemingly at each other's throats. Cisco had on the strange goggles he was wearing at the church and was glaring at Wells. Though the goggles somewhat ruined the effect of his glaring. At the same time, Wells was glaring at Cisco while brandishing a soldering tool like he was considering using it on the engineer.

Jax was oddly absent, but Stein stood a few feet away, watching them argue with his lips pressed thinner than his hair. By the put-upon expression on his face, Lena surmised he was debating if getting between them was worth the effort. Lena deduced from their shouted words that neither of them had any luck locating their Earth-X interlopers.

"Gentlemen!" Stein enunciated loudly to cut through the racket the two were making. When both men fell quiet and turned to face him, he continued. "Perhaps a cessation of hostilities is in order, given our new observer."

Stein's words prompted both men to turn towards the door and spot Lena watching them bicker with her arms crossed over her chest. Both men grew uncomfortable at being caught arguing like children. Lena didn't care for their petty quarrel; she was simply annoyed that they were under threat of Nazi attack and these two were wasting time. Deciding to put her negative feelings to good use, she settled on the plan of berating them, just a little, to get them to focus. Dawning the face of the L-Corp CEO she addressed the arguing men.

"I take it neither of you has turned up any results." Lena spoke in a flat tone, but they could all hear the undercurrent of disappointment in her tone.

Of the three of them, Stein found his voice first. "I'm afraid our efforts to find any forensic clue as to their whereabouts have come up empty."

After the professor broke the ice, Cisco found the courage to speak as well. "And I wasn't able to vibe anything off any of this stuff." He gestured around to the various weapons and uniform pieces they had collected from the church. "It's weird. Every time I try to get a vibe off something all I get is distorted images that I can't make out. it's almost like something is interfering with the signal."

"The Earth-Xer's probably don't like it when Vibers spy on them. They must have taken precautions to prevent exactly that, so you might as well give up on trying to find them that way Ramon." Wells sniped. Obviously trying to draw attention away from his own failure.

Lena wasn't about to let him get away with that.

"So, you have nothing and decided it would be more productive to take a break to berate each other?" This time her tone was laced with judgement. Her words had Cisco looking down at his shoes and Wells scratching the back of his neck while he avoided looking at her face. It was a point of pride for her that she was able to chide arrogant men like Wells into submission. Unfortunately, it brought her no pleasure at the present.

"That about sums it up. Yes." Stein spoke, the only one of the three of them that was able to look her in the eye.

She stared them down for a few more seconds before speaking. "I'm going to go back to the Cortex. If you can find it within yourselves to act like real scientists, then I suggest you get back to work."

"We're gonna… you know… get back ta work." Wells mumbled as he turned back to his worktable, Cisco and Stein doing the same.

Lena didn't spare them another glance as she turned and marched back the way she came.

As she reentered the central hub of Star Labs, the first thing that Lena noticed was Felicity staring down at the computer console that had begun to beep. "Break in at Dayton Optical Systems," The computer genius announced to the room that currently contained only her, Lena and Iris.

"Felicity, I know your first instinct is to help. But given the current circumstances maybe this is better left to the proper authorities." Lena tried to reason with her, simultaneously announcing her presence to the room.

Felicity looked back at her, "Any other situation I would agree with you. Except its being robbed by Nazi's." She pointed at the screen, showing security camera footage of soldiers with red armbands storming the building.

"I'll get Barry." Iris announced before she ran off. Lena pulled out her phone and texted Kara to get to the Cortex asap. Not two seconds later, a whoosh of air signaled Kara's arrival.

"What's going on?" She immediately asked Lena, whose only response was to gesture at the screen where the security camera footage was still running. "I'll get Oliver. You call the others back here and have Cisco ready to open a breach in case we need backup." Lena nodded at her instructions.

Lena watched in confusion as Kara grabbed her shirt by the placket before ripping it open to reveal that she kept her super suit on underneath it. Another 'whoosh' and Kara was gone.

Lena tried to ignore the realization of why Kara never seemed to wear the same shirt twice in favor of contacting everybody else.

Over the next hour, every hero and scientist they had sat in the Cortex and waited for some sign from their three best heroes. Felicity tried to follow what was going on with the security cameras, but the parallel Earthers must have disabled them shortly after the initial break-in, because all they could get on the monitors was snow. Oliver and Kara didn't have their comms, not expecting to need them at a wedding, and Barry must have turned his off because try as she might, Iris couldn't raise him. They were completely in the dark and forced to wait to see if their friends (and love interests in the case of Felicity and Iris) were okay.

It completely sucked. Lena hated having nothing to do but wait. And she wasn't the only one.

Felicity, Wells and Cisco were scouring the computers of Dayton Optical. Looking at all the projects they kept on sight for any hint as to why the Nazis were there. Caitlin and Alex had taken up residence in the med lab to prepare for any possible injuries that their heroes might come back with. Lena was seated in a chair behind the main console trying to think about anything else while waiting for some sign to let them know if they were needed or not.

She couldn't help but remember Caitlin's words from earlier. About how easy it is to feel useless, watching those with powers and combat skills go off to fight the bad guys. When it was just Supergirl, the hero she admired on the news risking her life to save the world, she found it a little thrilling. Because Supergirl was never afraid. Supergirl never worried about individuals. Supergirl didn't concern herself with mundane things about everyday life.

She never doubted that the powerful, godlike, technologically advanced alien, symbol of hope for people the world over would win. But she wasn't a symbol anymore. She was Lena's friend Kara. The quirky blonde who hosted game nights and had an unhealthy obsession with pot stickers. The woman who loved hugs and confided in her that one summer, she broke three of Eliza's lamps while trying to learn how to tap dance. Kara feared losing people, she worried about paying her bills and getting her articles in on time, and nobody cared as much about others as Kara Danvers.

She wasn't a symbol anymore.

And Lena found it a lot harder to just sit back and watch as her best friend risked her life. And it was while she was waiting that an idea began to form. An idea inspired by her brother of all people.

The murderous megalomaniac brother, not the stoic British one.

Lex built his Lex-o-suit so that he himself could combat Superman. And ever since his arrest it had probably been sitting in one of his hidden lockups. Just waiting to be put to better use.

With a few tech upgrades and modifications to better fit a woman, I won't be stuck on the sidelines like this again. Lena resolved to make finding it her new pet project when they got home.

Unfortunately, that didn't help her at the moment. But the sight of Kara, Barry and Oliver walking back into the lab had the entire room releasing a relieved sigh.

"They got away." Oliver offered as a greeting as soon as they entered. Kara didn't say anything, but she did sidle up next to Lena, put her hand on her shoulder and give it a brief squeeze in reassurance. Which Lena appreciated and made her smile at the blonde.

"Felicity, we need you guys to hack into Dayton Optical and find reference to a big red jewel. The Earth-Xer's managed to get away with it," Barry directed more usefully.

The aforementioned woman rapidly began typing on the central console. "I already accessed their system to find out why they went there in the first place. Now that I know what to look for it shouldn't take- bingo."

Wells standing next to her made a few keystrokes and put an image of a twenty-sided polygon on every screen in the room.

"Dayton Optical calls it the prism." Felicity clarified.

Wells shook his head in confusion. "What on Earth do they need a sub-light generator for? It's basically a spectral emitter that-"

"Uses quantum entanglement." Felicity finished in a little lack luster tone, just as stumped as Wells. But Lena felt a rock settle into her stomach.

"It can also be used to create a stable fusion reaction." Caitlin threw out as she and Alex entered the room, proving she wasn't just a medical doctor.

"That all means what exactly?" Iris asked the room at large. Every scientist there looked at her strangely. "No, guys seriously. I would like to know what you're talking about."

Feeling the rock in her stomach getting heavier by the second, Lena bit the bullet. "They're hoping the Nazi's are going to use the device to build a neutron bomb."

"Boom." Felicity quietly exclaimed for emphasis.

Iris looks like somebody killed her dog. "I take it back. I don't want to know." She paused as Lena's words fully registered in her mind and she turned back to face Lena. "Wait, I'm sorry, but did you just say, 'they hope the Nazi's are building a bomb?' What, you know something worse they could do with it."

Every eye in the room turned to face Lena who pointed at one of the computer screens displaying the prism. "I don't know if it's worse. But I do know that devices like this are at the heart of every piece of red solar tech my brother Lex ever designed. So, theoretically it could be used…"

She trailed off as she turned to look at Kara, who looked distressed as she realized what Lena was thinking. "It could be used to shut down my powers."

"Woah."

"Wait, what?"

"Time out. Flag on the play."

Several people spoke in alarm at the same time. Cisco was even holding his hands up in the "T" position, like a ref at a sporting event. But it was Felicity who managed to articulate the thoughts of everybody in the room.

"What do you mean shut down your powers? How is that possible?" The tech genius practically interrogated the Kryptonian.

Kara bit her lip, thinking seriously about remaining quiet, before ultimately deciding that they needed to know. "On my home planet of Krypton, I wasn't that different from humans. I wasn't bullet proof. I couldn't fly. I didn't have superpowers until I came to Earth. Because on Krypton our sun was red." Kara paused and took a deep breath and let it out through her nose to steady herself before continuing. "Under the light of a yellow sun, the cells in my body react differently. That's the source of my powers. But under the light of a red sun, I'm as human as you are."

"So, they could use this thing to neutralize Kara. And with a Kryptonian on their side, they could wipe the floor with all of Earth's heroes, the military, every system of defense put in place." Alex continued where her sister left off. "They wouldn't need neutron bombs to conquer this Earth."

"I was right. I really didn't want to know." Iris mumbled, feeling the same rock as Lena settle inside her.

"You and me both sister," Caitlin couldn't help but comment as she leaned her arms on the computer console.

"Okay, if I were them. That sounds like the plan I would go with. So, what do we do about it?" Sara said, trying to force everybody's thoughts away from the horrible mental pictures running through their heads.

"If you give me access to the resources here, I can construct a yellow sun grenade. That way, if they try to shut down Kara's powers, we can recharge her in an instant." Lena offered up. And again, stunned the people in the room.

"Wait, seriously? You can just build us our own portable sun?" Cisco asked while trying to grasp the mechanics of a device like that.

"Our only other option would be to stock up on kryptonite." Alex answered the question. Kara looked at her sister like it physically pained her to hear Alex say those words. But she didn't refute them.

Felicity threw a wrench in that plan. "That's not an option. Kryptonite is a lot harder to find on our Earth than it is on yours. What little we've managed to find was only enough to make a single arrow."

"She means this arrow?" Oliver finally spoke up as he pulled a bloodstained arrow out of his quiver. Kara took several steps back as he moved to the middle of the room to hand said arrow to his girlfriend. Felicity received it with a grimace.

She looked up at Oliver. "Please, for the love of God, tell me you did not use this on Kara?" She was certain he hadn't. But they had suffered so many emotional upheavals in the last few days that a part of her just needed to hear him say it.

"In a way he did." Barry spoke morosely, as he came up to stand behind Oliver in a show of support. "But they call her Overgirl."

Felicity didn't like what she was hearing. "I'm sorry, but what is that supposed to mean?"

Barry looked at Oliver briefly before deciding to spare him from having to answer. "The black archer and the Kryptonian on their side. They're doppelgangers of Oliver and Kara."

"Oh snap."

"This is not good."

"You've got to be kidding me."

Cisco, Wells and Iris all spoke at the same time.

The dejected look on Kara's face was all the proof Lena and Alex needed to believe their words. Now they knew why Oliver and Barry had been so quiet up to this point. They were distracted by the revelation of who they were fighting.

But they were all floored by Barry's next revelation. "To make matters worse, they have a speedster on their side. Its Thawne."

There were no exclamations of shock or outrage at those words. Which might have been helpful, because Lena didn't understand the sudden shift in the atmosphere of the room. She didn't understand why everybody else was staring slack jawed at Barry now.

Who the hell is Thawne?

"You mean a parallel Earth-X version of Thawne?" Iris tried to clarify, the first person to regain the ability to speak.

Barry shook his head sadly. "No. I mean our Thawne, from our Earth. He's working with the Nazis."

"I'm sorry, but who the hell is Thawne?" Alex finally asked, saving Lena the trouble.

"Eobard Thawne is a speedster from the future. He came back in time to kill Barry as a child. Before he could ever grow up to be the Flash." Caitlin tried to explain. But Lena got the impression that she was holding something back. That feeling was reinforced by the apprehensive looks she was sending Barry.

He sighed before continuing. "He failed to kill me. So, in order to hurt me so profoundly that I would never become the Flash… he murdered my mother."

Lena was careful not to show her emotions. Mothers were obviously a sore subject for Lena, having watched her own mother drown. She could certainly sympathize with Barry, but she couldn't empathize with him. It's one thing to watch somebody you love die, it's a whole other thing for them to be murdered. He… they didn't need her pity right now; they needed her help.

Time to get this strategy session back on track.

"I can help you with your kryptonite problem." She spoke after a brief silence. A feeling of dread pooling in her stomach. She had planned to talk to Kara about this once they were back on their own Earth and finally had that sit down. Preferably on her big soft couch with pizza and several pot stickers resting between them. And whatever else she could think of to keep Kara in a good mood.

But the presence of Nazis threw that plan out the window. This certainly wasn't the ideal situation to reveal this information. But not only could this help them now, but Lena refused to hide anything. Especially not from her friend. That's what she told herself, but she couldn't shake the feeling that she was hammering the nail on her own coffin.

"What are you going to do? Build us a kryptonite tracker after you finish building your artificial sun?" Wells asked her in derision, thinking she was trying to show off for her superpowered colleagues.

Lena hadn't let him intimidate her yet and she wasn't going to start now. "Well, I could do that. But seeing as I know how to make kryptonite, I thought we could just manufacture some."

Total silence, quieter than a tomb, reigned in the room at her words. That was interrupted by Alex saying flatly. "What?"

Lena sighed, before squaring her shoulders and turning to face Kara and her sister head on. Might as well get it over with.

"I figured out how to make kryptonite. And I've been manufacturing a small supply at L-Corp." Half the room was staring at her with their mouths open. The other half wore carefully guarded expressions, thinking the only reason somebody would even have kryptonite would be to hurt Kryptonians. Oliver reinforced that theory when he made a kryptonite arrow.

Kara's face started to shed the blankness brought on from shock and began twist into some other emotion. Lena couldn't tell if it was anger or despair, but she wanted to stop it before it could go either way.

"I was going to tell you-" Lena tried to explain, but Kara steamrolled over her.

"When Lena? When were you planning to tell me that you were manufacturing something that could kill me?" Kara's voice was only one octave short of yelling. Clearly, she had decided to go with rage over despair.

But she wasn't going to let her friend be mad at her without getting a chance to explain. "I had planned on telling you Kara. I was going to tell you when we finally had that conversation we said we would have before Harry left."

"Harry? Do they have their own Wells on their Earth?" Cisco tried to covertly whisper to Caitlin but received only an elbow in the side for a response.

"Why would you be manufacturing kryptonite at all?" Kara accused Lena.

Lena took a deep breath and steeled herself for an uphill battle before speaking. "Several reasons actually. The first is protection. Not from you, but from other Kryptonians. Face it Kara, of the small number of your people that are left in our universe, the only ones who haven't threatened our Earth are you and your cousin. It's not an outlandish idea to be prepared incase more like your aunt or Zod show up."

Remembering several news broad casts she witnessed, she pointed at Alex. "Clearly the DEO agrees with me, or they wouldn't have issued Alex a kryptonite powered exo-suit."

"Actually, I gave up that suit along with the rest of the DEO's supply of kryptonite after the Metallo incident." Alex admitted sheepishly. She, like everybody else in the room, was a little afraid of getting involved in this discussion. The DEO may have surrendered their kryptonite to Superman, and she certainly didn't want to hurt her sister, but she couldn't deny that it had been invaluable in fighting off Astra and her followers. A blade made of the glowing green rock had saved J'onn's life at one point.

Lena leveled the red head with a look that was half bitter and half condescending. As if having a change of heart and getting rid of the stuff erased the fact that it had been their primary weapon for years. Lena decided that she and Alex should have a talk of their own at some point in the not-so-distant future.

"Another reason is medical research." Lena continued, after looking back at Kara. "I know kryptonite is harmful to you, but I believe there is great potential for its unique form of radiation. I'm already exploring it as a means of curing cancer."

Lena knew she had struck a blow for herself this time. The anger seemed to drain right out of Kara at the realization that kryptonite could have some real benefits for helping people. But she still seemed skeptical of this, so Lena decided to offer a little hope to drive the point home. "Look, when we get back to our Earth, I'll take you to my lab. I'll show you all of the research I've been doing, and you can see for yourself that there is more to this substance than just hurting you."

Kara bit her lip as she considered what Lena was offering to her. She could see what this really was, a show of trust. Not just a chance to see her friends most top-secret research in her most guarded lab. But proof that Lena was letting her in.

"Okay," she began with a nod. "As soon as we get back?"

"I promise." Lena spoke with a smile as Kara accepted the olive branch she was holding out.

There was a beat of silence as the two of them looked at each other, but it was broken when Lena looked back at Cisco. "I should probably get started. Do you mind if I use your lab?"

"No problem. I'll go with you and show you where everything is." Cisco moved for the door.

"I think I'll go with you. I'd like to see this." Wells said as he moved to follow, leaving everybody else in the Cortex to do their own thing.

Fortunately, with the supplies and technology they had at Star Labs they would be able to make a small amount of kryptonite. Unfortunately, it would take them several hours before the mixture they had concocted was properly irradiated and would begin to crystalize.

They were making much faster progress on the yellow solar grenade. Despite some issues with her coworkers.

"Don't forget to laminate the core materials before you install them. We want it to emit light. Not explode." Lena instructed Wells as she watched his progress from her own workstation.

Wells grumbled at her. "Yes, I know. I'm not an idiot." Lena pretended to turn to face Cisco but made sure to watch Wells from the corner of her eye. She smiled to herself when he discretely removed the necessary parts he had just installed and moved to follow her instructions.

"Cisco, how is that casing coming?"

"Just finished." He announced as he brought the two baseball-sized half oval pieces of metal to her. "Made to your exact specifications." He emphasized. Probably to annoy Wells.

"Core is ready," Wells said as he slipped the laminated materials in before he too brought them over to her.

Lena made a final solder on the circuit board she had been working on and turned to accept the core from Wells. Taking one of the two halves from Cisco, she carefully situated the core inside of it before taking the other half and fitting it over the exposed core. Twisting the two halves in opposite directions until she heard the click signaling it was locked in place. She picked up the circuit board she had been working on and slid it into the open slot at the device's apex.

As soon as the panels on the sides lit up yellow Lena knew it was ready.

"That's it? That little thing is going to save us if the Earth-Xer's manage to shut down Kara?" Wells sounded skeptical. Lena didn't dignify him with a response.

It turned out they were just in time as Felicity's voice came over the intercom. "Guys, hope you've got that thing working because we've got a location."

Lena carried the solar grenade with both hands as the three of them rushed back to the Cortex. Everybody was dawning their respective suits as they were gearing up for the fight. Lena spotted Alex loading a full magazine into her gun and moved towards her. She looked startled for a moment when Lena held out the device to her.

"In case the worst should happen."

Alex looked Lena in the eye before nodding her head and acccepting it. She attached it to her belt before heading for the door with the rest of the heroes intent on sending these gestapo thugs back to their own Earth.

_o0o_

Oliver walked into the seemingly abandoned warehouse to find several Nazi thugs milling about. One spotted him and shouted, "don't move," and every weapon in the room was leveled at him. Oliver didn't even flinch as a streak of yellow lightning zipped through the warehouse. Every Nazi in the room was out cold before they could get a single shot off. Leaving Oliver standing at the door and Barry in the middle of the room.

"You couldn't have left one for me?" He asked. He had wanted to shoot something.

"I'm saving Nazi you for you." Barry answered as Oliver moved towards him.

"No sign of the prism." Alex informed as she moved in from another door. Sara was at her side with her eyes fixed on something behind Barry.

"We got incoming," she said as she extended her staff. Barry and Oliver followed her gaze to see several more soldiers charging into the room from all sides with their guns drawn.

They were surrounded.

The sight of a red lightning bolt rushing into the room drove thoughts of the soldiers from Barry's mind. Yellow lightning surrounded him as Barry moved to engage Thawne. Alex drew her gun, and Oliver notched an arrow as all hell broke loose.

Shots were fired, arrows went flying, and Sara beat men bloody as she swung her batons at the small fries that tried to waylay them. Red and yellow bolts of lightning could be glimpsed as Barry and Thawne chased each other around the room. A whoosh overhead made Alex look up to spot the evil version of her sister fly over her head and collide with Kara. The two of them began to grapple in midair.

It was going well. The pawns were dropping like flies while the big pieces were engaged. But despite everything going according to plan, something didn't feel right to Alex.

"I see their Flash and their Supergirl. But where is their Arrow?"

She never got an answer as more soldiers came pouring in and they had to get back to fighting. That was the moment Firestorm flew in and started throwing fireballs at groups of the bad guys, blasting them off their feet.

Oliver showed no mercy to the soldiers who tried to engage him. He took kill shots on everyone he saw. The unlucky ones who got close enough to try and throw a punch or a kick wound up flopping around on the ground like landed fish with broken bones courtesy of his bow and a few well-placed punches and kicks of his own. But this victory was short lived as Overgirl dropped down right in front of him and punched him full in the chest.

He felt his Kevlar crack under her knuckles as he went flying and collided with a wooden crate. The wood shattering beneath him. Oliver laid on the ground as he tried to pull air back into his lungs, trying to ignore the feeling that had he not been wearing armor he would have had his chest caved in.

Rolling on to his side he looked around the room. Barry and Thawne's lightning trails were still flitting all over the room. Alex was shooting or beating the crap out of any soldier who got close to her while Jax and Kara flew overhead sending fireballs and heat vision blasts respectively at any enemies they could.

They were all okay. But Sara was in trouble. Somehow, she had gotten into a fist fight with Overgirl and was now backed up against a concrete pillar with the murderous Kryptonian's hand at her throat. Oliver spat out a glob of blood before forcing himself up to his knees and firing his kryptonite arrow at her head.

She caught it by its shaft before it could reach its intended target. She threw Sara aside like she was nothing before making a show of snapping his only weapon against her in two and dropping the pieces.

"Burn." She said, before firing heat beams from her eyes. Only Oliver's quick reflexes allowed him to dive out of the way in time.

A flying kick to the face from their Kara sent the evil one flying across to the warehouse to land in a heap.

That moment of victory was short lived as Sara pointed behind Oliver and Kara. "What the hell is that?"

They turned to see a robot stomping towards them. A robot that had a familiar glowing green rock at its heart. The blood drained from Kara's face as she spoke. "Metallo."

It fired a burst of green energy that struck Kara square in the chest and knocked her out cold. Firestorm tried to charge the metal man only to be, almost negligently, backhanded into another pillar. The force of the impact split Jax and Stein and sent them skidding in two different directions. That was when Overgirl used her super speed to punch Barry. All Oliver, Sara or Alex saw after that was a bolt of red lightning before blackness.

Eobard Thawne gazed down at the prone form of his nemesis with glee. Finally, he had the Flash exactly where he wanted him. On the ground, at his mercy.

I'm going to enjoy this. He thought with some sadistic glee. But was distracted by the sound of the alien bitch greeting her husband as he entered the warehouse they occupied. He must have succeeded in securing Star Labs. He may not have powers but at least he's good for something.

"Thawne!" The dark archer shouted. Turning his head from where he had been staring at the defeated heroes, he saw the Fuhrer and his wife both watching him.

"Sorry. Lost in thought," He temporized.

"Time to focus." Oliver Queens evil twin insisted. "Wake them."

Thawne clenched his teeth at being ordered around by this powerless Aryan stooge. He would like nothing more than to vibrate his hand right through his chest and shred his heart like tissue paper. But, for the time being, he still needed them. He took a remote out of his pocket and pressed the button.

The heroes all returned to the waking world with a violent jolt. They immediately noticed the hand cuffs restraining them. But it was a moment more before any of them noticed the soldiers surrounding them. Thawne couldn't be more pleased with himself as he and the twisted parodies of Kara and Oliver watched the heroes take stock of their situation. Their wrists chained to the floor. The restraining collars around their necks and Metallo standing at the far end of the warehouse. Ready to attack again on command.

Thawne smiled at them as he mockingly clapped his hands. They all glared at him as they rose to their feet. "Well, well. Here we are. This has been great fun. For me. Not so much for you." He was speaking to Barry who glared back. Never having been afraid of him. "Just think. All the times you've killed me, and now here I only have to kill you once," the bastard spoke magnanimously. As if he was doing them a favor by taunting them. "Of course, until then, I can just do this."

He held up a small remote and pressing a button with his thumb. They were all hit with enough volts to make them spasm uncontrollably and fall back to their knees. He carried on for a few seconds before Overgirl put a stop to it.

"Enough Eobard. Enough," The other Kara barked as she waltzed up to them with the other Oliver at her side, looking every bit as smug as the yellow clad speedster. "We need them alive."

Thawne looked enraged that his fun was being curtailed. "Not all of them," he said petulantly, eyes on Barry the whole time. Leaving no doubt as to who he was imaging electrocuting to death.

Overgirl ignored him. She was unconcerned with his ego driven need to prove his superiority.

Alex decided to try and goad him into a mistake. "You should listen to her. We know that if you had wanted to kill us you wouldn't have put these dog collars on us."

Kara scowled at her smirking double. "Now I know what it's like to hate myself."

The Kara wearing the ugly black lipstick scoffed at her before grimacing and falling to her knees. The heroes looked on curiously as the Fuhrer dropped to his knee beside her. He took her hands in his own as she started panting for breath. It was obvious to all present that she was in pain. But nobody knew what had caused it. Sure, Kara had managed to get a few good hits in against her evil twin. But she couldn't have done any lasting harm.

"The pain," She panted through grit teeth. "I don't know how much longer I can bare it."

Her husband smiled at her. But they could all tell that there was something wrong with the look. Something fake. Like he was just showing her what he thought she needed to see. "It's alright. Everything's going to be alright. Because we found her. We found her. And now we have her." He said as his eyes turned to glance at the good Kara.

He looked back at her as she met his eyes. "I love you. Very soon this nightmare will be over, and I'll take you home." His eyes turned hard as he growled his next words. "Now stand up." His voice made it clear that he wouldn't tolerate it if she didn't.

They didn't know what had brought on this bout of weakness, but he clearly didn't like seeing it. With a pained grunt behind clenched teeth, she rose back to her feet.

"Star Labs is secure." He said to the horror of the good guys. All of them were afraid of the fates of those they had left there, thinking they were safe away from the fighting.

"If you hurt my friends-" Barry started before he was cut off.

"I did hurt your friends." He held his hands behind his back as he stepped towards them. "I rather enjoyed hurting your friends."

"Are they alive?" Their Oliver asked, unsure which answer he was hoping for. 'No, they're dead,' or 'yes, they're our prisoners.'

"For now. Whether they stay that way will depend on your Kara's cooperation. We don't need it, but it is preferable."

"What do you want my sister for?" Alex butted in.

"To save my life," Overgirl answered back, before turning to mock her doppelganger. "That is your little mission statement isn't it. Help people. Save lives. Well now is your chance to save somebody worthwhile."

Thawne could see that they weren't following, so he decided to help them by twisting the knife a little more. "The general is dying. She's been exposed to too much solar radiation."

"But we can save her." The Fuhrer spoke gazing at her. "We're going to save her. All we need is a new heart. And luckily, on this Earth, we've found the perfect donor."

The bottoms dropped out of all their stomachs as they realized what they had planned. They were going to cut out Kara's heart while she was still alive and put it in their Kara.

"You stay the hell away from my sister." Alex snarled, unafraid of the overwhelming odds against them in the face of a threat to her little sister.

Overgirl smiled at her and hmm'd. "Such loyalty. My sister tried to kill me."

"So, Lena was right." Barry grabbed their attention. "You stole the prism so you could weaken Kara and…"

Barry abruptly stopped speaking and turned to stare off into space. Yellow sparks igniting in his eyes.

"What was that?" Thawne asked Barry, looking at him dead in the eye. "You sensed something, didn't you?" Barry didn't answer him. Thawne didn't need him to. He recognized the signs.

"Something new has come to this Earth." Thawne's words had every Nazi in the room tensing in preparation for whatever had just arrived. At the same time, every hero in the room grew just as nervous. They had just had their collective asses kicked by their evil counter parts. They didn't need some other threat from yet another Earth to show up and make things worse than they already were.

"What just came to this Earth?" the Fuhrer demanded to the surprise of the heroes. Whatever it was, clearly they hadn't been expecting it.

"Can't be certain. Nor do I know why I didn't sense it as well." Thawne answered in frustration, with a small twinge of something else in his voice. Sara scrutinized him a little closer. She had heard that tone out of him before. And he certainly looked apprehensive about something.

"What could cause that?" Overgirl probed. "A dimensional tear? A breach to another Earth? A temporal portal?"

"All of the above, plus a particle accelerator. But whatever it is, it could be trouble." He turned from her to face her husband. "Have you checked in with our soldiers at Star Labs since you left?"

Evil Oliver's eyes narrowed at Thawne claiming any ownership over his soldiers. But he ignored it in favor of putting a hand to his earpiece and trying to raise them.

Kara didn't hear him ask for a report into his comms. She was too preoccupied with the feeling of hope bubbling up in her chest. A world under siege, its heroes backed into a corner and now a breach opening and letting something new onto this Earth. 'Where have I seen this movie before?' Kara thought sarcastically as she turned to lock eyes with Alex. One look and she knew her sister was having the same sense of déjà vu that she was.

"I can't raise anyone on comms. What the hell is going on?" the Fuhrer demanded of Thawne. He seemed to know, or at least suspect something.

But before the speedster could answer, Overgirl cut in. "I think they know." She had seen the looks exchanged between the sisters.

Seeing as the cat was out of the bag, Alex decided to quit being subtle and turned back to ask Kara, "Are you thinking what I'm thinking?"

Kara shrugged her shoulders in response. "The circumstances are right. The question is 'can he help against these odds?" She asked while nodding at the speedster in yellow standing next to her warped mirror image.

"Who are you talking about?" Overgirl spoke, the command to 'answer or else' left unsaid.

Feeling more hopeful, Kara shrugs mockingly. "Just a black clad speedster we're familiar with."

Overgirl's scoff at the word 'speedster' was drowned out by Thawne's panicked shout, "BLACK!"

A distant 'boom,' like a clap of thunder, grabbed all of their attention. Barry was the first to realize what it meant, and shouted, "Everybody down," before he dropped to the floor. The Nazi's ignored his words, thinking they could handle whatever was coming.

Most of the heroes immediately dove for the ground, thanks to their better reflexes. Just in time, as a streak of silver lightning phased through the wall of the warehouse. Thawne and Overgirl acted to intercept, but whatever this was had a running start, had come in through the wall behind them and was aiming for another target.

The lightning struck Metallo.

With force equal to one of Overgirl's punches, it collided with the metal man's chest. The impact ruptured his kryptonite power core, causing an explosion that sent the Nazi Kryptonian and speedster flying back, and knocked everybody else off their feet.

Through his blurred vision, and the ring in his ears, Thawne could make out brief flashes of silver as he tried to regain his bearings. Thawne gave his head a shake to clear the cobwebs before rolling off his back and on to his stomach. He looked up and froze at the sight of the figure crouched with its back to him. Cold dread settled over him, and a shiver like somebody had poured ice water down his back ran down his spine. This wasn't supposed to be happening. He had been on another Earth. Hiding out in its timeline. The Black Flash shouldn't have been able to find him. Not this soon.

Then, the speedster turned, and all dread fled from him in an instant. Leaving behind confidence and enough amusement to make him smile.

"Who is that?" Overgirl snarled next to him, rising to her feet. Outraged that this single speedster had dared to attack them.

"Paladin," Thawne sneered in answer. "For a moment, I actually thought we were in danger."

The only response he received was the sound of metal scraping as their new opponent unsheathed his claws. Thawne only smiled wider. "I'm going to enjoy this." Certain of his superior speed, he charged. His intent to put an end to the other speedster.

However, before he could get close enough he was intercepted. By a fist in a red suit surrounded by yellow lightning coming out of nowhere and colliding with his face sending him rolling back along the ground.

Looking up from the ground for the second time in as many minutes, he saw Barry Allen standing in front of Paladin. Clarity dawned on him as he turned his head to where the other heroes had been chained up. His eyes confirmed what his mind already suspected. While he and the other Earth-Xer's were picking themselves up after the destruction of Metallo, Paladin had time to move against them. Their enemies were free of their restraints and back on their feet.

The voice of his hated rival drew his eyes back to the other speedster. "Alright Thawne, it's time for round two." With those words, both the red and yellow clad speedsters re-dawned their masks. The three speedsters crouched into a ready position and charged at each other.

Okay, let me say sorry for the delay in posting this chapter. I wanted to try and finish the entire Earth-X saga in just two chapters, but when this one started running over twenty thousand words, I figured splitting it into three was the right call. So, with a little rewording to leave you guys on a nice cliffhanger, this is part 2 of the story arc.

And guys, I know some of you were disappointed by the lack of Harry in the last chapter, and I'm sure some of you aren't going to like his late appearance in this chapter, but it was all for a purpose. Its going to highlight something about Harry's personal timeline in the next chapter. Which is going to get kind of dark because I guarantee that visiting Earth-X, meeting Leo and the rebels, everything after this point is not going to go how you're expecting.

And please don't hold the Lena centric ness of this chapter against me. I wanted her, the person most out of place on another earth with new heroes, to have the spotlight. Thought it would make for a better chapter. And that conversation between Lena and Caitlin was purely for my indulgence. Because Caitlin is my favorite Flash character and I think she gets the short end of the stick way too often. And that "superpowered boys club" comment was my little homage to the episode "Agendas" of Young Justice. I thought Wonder Woman's line of "Athena knows the league could use more female members," was just gold. And since this episode took place around the same time of year as that episode, I saw an opportunity to give a shout out to the ladies. Boom.

And yes, I changed things so Cisco wasn't knocked out in the church. I figured that's what would happen had Lena been there to save him from himself. But I still made him useless. My thinking is that the Earth-Xer's were watching our heroes and planned how best to deal with them. They wouldn't want Cisco (or any viber) keeping tabs on them on their Earth. They couldn't have known he was going to be knocked out in the first fight.

Well, that's everything I have to say, for now. I'm already well into Chapter 15 which will hopefully be up before Thanksgiving. A shout out to my Beta's for their hard work. This story wouldn't be what it is without them. Good morning, good afternoon, and goodnight.
