"CCPN is reporting that Dr. Harrison Wells, the infamous founder of S.T.A.R. Labs who uncharacteristically has gone unseen for nearly four months is now a wanted man. These images and messages went up moments ago throughout Central City by Zoom." The news anchor announced on TV as Harry was in his office in S.T.A.R. Labs, watching the news before Hewitt entered.

"Have you seen channel 52? You're not safe here, Dr. Wells. Zoom's looking for you." Hewitt said.

"I know what he's doing. Alert security. Evacuate S.T.A.R. Labs. Lock down the facility." Harry ordered.

"What about you?" Hewitt demanded.

"Don't worry about me, Henry. Just get everyone out of here now. Now! Go!" Harry ordered and Hewitt ran off.

"Harry!" Cisco raised his hands as Harry aimed at him upon entering. "Don't shoot!"

Harry sighed. "Damn it, Ramon." Cisco relaxed as Harry lowered his weapon. "Where's Allen?"

"Zoom took him." Cisco explained.

"What?" Harry demanded.

"We tracked down Deathstorm and Killer Frost, met my doppelganger, Reverb... super evil guy, super evil powers. The three of them almost took down Barry until Zoom showed up, killed Cisco-2, killed Deathstorm for hurting a speedster. But then he left Killer Frost alive and then took off with Barry." Cisco said quickly.

"How are you still alive?" Harry inquired.

"Looks like he cares even less about me than you do, Harry." Cisco shrugged.

"No, no. Zoom doesn't do anything by accident. Did he follow you here?" Harry asked.

"I've seen 'Heat' like fifty times, OK? I know how to shake a tail. He didn't follow me. But check this out." Cisco showed Harry Reverb's goggles. "I jacked these from my dead ringer. I think we can tweak these puppies, use them to find Zoom."

Harry took the glasses from Cisco's hands. "Damn it, Ramon, we don't have time for this. Zoom is hunting us. Zoom is hunting us! We need to make an alternate plan, because if we don't, Zoom—"

"Stop thinking like that, OK?" Cisco snapped, taking back the goggles. "We're gonna find Jesse, and we're gonna find Barry. I know we will."

Cisco then saw Barry's doppelganger in cuffs in a storage room as he got an idea.

Harry uncuffed Allen, who clutched his wrist. "Dr. Wells, this is very disappointing. I mean, the two of you should be ashamed of yourselves. You can't just lock someone in a room like this. How long was I in here for?"

"Barely a day." Harry said dryly.

"One day? One day? Oh, jeez, Patty must be freaking out." Allen panicked as they entered what seemed to be Earth-2 S.T.A.R. Labs' Cortex. "Dr. Wells."

"Yeah?" Harry asked.

"Doctor, I'm not sure if you're aware of this, but my girlfriend is one of the smartest CSIs in CCPD. She's got to be very upset." Allen said.

"Whoa, this is heavy." Cisco muttered.

"It certainly is. And I'm sorry, fellas, but I demand to know what the heck is going on here this instant." Allen ordered.

"Barry, this is a very long story." Cisco snapped.

"One that we don't have time to tell right now. We're sorry we locked you in that room for a day, but right now, you need to leave. You need to gather—" Harry stopped, when an alarm rang throughout the facility. "He's here."

Zoom entered the ground floor, knocking out the guards and nearing Hewitt, grabbing him by his throat and pinning him to the wall. "Where are Wells and his friends?"

"Dr. Wells, hey, what the heck is going on?" Allen demanded as they were running down the corridor.

"Oh, Zoom's after us." Harry said.

Allen looked confused. "Zoom? What do... Why would Zoom be after you?"

"That's part of that long story I was telling you about." Cisco explained.

Allen looked like he was about to have a panic attack, when the wall suddenly opened. "I don't know if I can deal with something like this."

"You have a Time Vault?" Cisco demanded.

Harry nodded. "Yeah. I'm an enemy of Zoom, and I need a place to hide when something like this happens. Get in!"

"Yes, sir." Allen nodded as they entered the Time Vault but he panicked as he heard 'woosh'. "That's Zoom! That's Zoom!"

"Ramon, shut him up." Harry ordered.

Cisco covered Allen's mouth as Zoom phased through the wall, looking around but it seemed he didn't see them as he sped off.

Allen sighed in relief as Cisco took the hand off his mouth. "Breathe, breathe, breath, breathe..."

"Fake wall." Harry explained. "He's not gonna fall for another fake wall. We need to move. We need to find a different place to hide and make a plan."

"Wait, wait... hey, hey, hey, hey." Allen stepped up. "No. I think before we do anything, you have to explain to me everything that is going on here."

Zoom's lair

Barry was examining his cell as Jesse stared at him. "You're wasting your time. I used to think I could escape too when I first got here. There's no way out."

Barry noticed the man in iron mask in the other cell, tapping on the glass. "Who is that?"

Jesse shrugged. "I don't know. He's been here since Zoom brought me to this place." The man tapped the glass again as Jesse sighed. "Stop, OK? Just... just, please, stop."

"Jesse, I think he might be trying to help us." Barry realized.

"Nothing is gonna help us." Jesse said brokenly.

"That's not true. We're gonna get out of here. Your dad's gonna find us, I promise." Barry assured.

"You sure have a lot of faith in a man who only cares about himself." Jesse snapped.

Barry looked at her sadly. "You know, I actually thought that at first too. It's not true. Every decision that he's made, every action he's taken since we've met, has been to save you. Your dad hasn't given up on you, Jesse. Don't give up on him."

A moment later, Zoom sped into the lair and Jesse screamed upon seeing him and sobbed. "Believe what you want, but the only reason that you're still alive is so I can kill you in front of your father. And the only reason your father's still alive..." He turned to Barry. "…is to get me your speed. Once he does that, he will die too."

CCPD

Allen rushed into CCPD as Patty hugged him tightly. "Oh, thank God. I was so worried. Where have you been, Barry?"

"Well, I—"

"Did you find Zoom?" Patty asked.

"Patty—"

"I hope you didn't tell anyone Laurel's secret because the last thing we need is people going after her." Patty whispered.

"Laurel's secret?" Allen repeated, not understanding.

Patty looked confused. "Barry, you've been acting strange these past two days. What's going on?"

"Well…" Allen sighed as he led Patty up into his lab. "It's best if I show you."

"So, you're telling us that the Barry from yesterday wasn't actually you?" Laurel asked, folding her arms as she had her eyes narrowed, while Patty stared in shock.

"No. No, look, I... I know that this is hard to believe, but I mean, it is just like that sci-fi series, 'Commander Carl, Space Marshal of the Galaxy'…"

"…where Carl ends up on another Earth on another universe." Patty nodded as she and Allen chuckled. "Awesome episode."

"OK, I don't speak geek, so I've barely got clue what does that mean but if I got this right, alternate universes?" Laurel asked.

"In a nutshell, yeah." Harry nodded.

"Does the police have any clues on Zoom? You've been looking for him. Right?" Laurel asked.

"Well, we've been unable to track him down and the police doesn't have any clues either." Patty said before turning to Laurel.

"Well, I haven't used my powers since I moved here, so Zoom probably doesn't know about me and technically, I'm not a meta." Laurel said. "But, the metahumans that are free are in his army, right? We just need to track down a meta who worked for him."

"A meta like Killer Frost?" Cisco realized. "Zoom let her live yesterday. Why?"

"Because she's his loyal soldier. She never disobeys him. I doubt she's going to help us." Patty said.

"I'm not so sure about that. If she loved Deathstorm as much as my Caitlin loved Ronnie, I think she'd be more than upset at Zoom for killing him." Cisco noted.

"Assuming you're right, how are we going to even find her?" Laurel asked.

"I think I may have an idea." Patty sat down at the computer. "I've been working on most cases, where Killer Frost was involved. If we can figure out the temperature fluctuations and pinpoint the certain area…"

"…we can get an approximate location." Allen realized as they smiled at each other and kissed.

"Well, this algorithm works on most metas, but not on Zoom. He's too fast to leave behind a trail." Patty explained.

The computer then pinpointed the location as it appeared on the map. "Looks like the best bet's the woodlands." Allen said.

"Best CSI geeks in Central City." Laurel chuckled.

"You know where that is, right?" Cisco asked.

"Yeah." Harry nodded.

"Let's go." Cisco said.

"OK." Allen said as he and Patty got up.

"Not without me." Laurel said.

"Wait, no."

"No." Cisco and Harry protested.

"Look, I have powers, OK? And what do you have? A hi-tech rifle? My powers may not work against Zoom's speed but with me you have better chances at surviving." Laurel insisted.

"And besides, more heads can always help, can't they?" Allen pointed out and Harry and Cisco considered.

Zoom's lair

The man in iron mask kept tapping on the glass as Barry listened. "That's not Morse code. I know he's trying to tell us something. We just have to find the pattern."

Jesse shook her head. "There's no pattern, Barry."

"You know, your dad, who I'm pretty sure is one of the smartest people to live on either of our Earths, told me the only person smarter than him was you." Barry said.

Jesse looked in surprise. "He said that?"

Barry nodded. "If that's true, we work together, I know we can figure this out." Jesse considered. "Worth a shot?"

"OK." Jesse nodded as they listened to the tapping. "Well, he never goes past five."

"What?" Barry blinked.

"He never goes past five knocks without pausing. Right? Listen." Jesse said as Barry listened before getting up.

"Hey, you're right. I think... I think I know what that is. It's a five-by-five tap code used by POWs." Barry said.

"That would only get us to 25 letters, and there's 26 in the alphabet." Jesse pointed out.

"Not if you combine C and K. They sound the same. Let's try it out." Barry said.

Jesse shrugged. "Worth a shot."

"All right." Barry said as they listened to the tapping.

"Two down, five across." Barry said.

"It's J." Jesse said.

"J?" Barry turned to the man in iron mask. "That's what you're tapping? The letter J?" The man nodded. "All right, what's next?"

Jesse listened to the tapping again. "A."

"All right."

The man tapped on the glass again. "Five down, four across. Y."

"J-A-Y?"

"You're spelling 'Jay'. As in Jay Garrick?" Barry asked and the man nodded. "He's... he's alive. But he's on my Earth." The man banged on the glass, seeming desperate and angry. "Hey, hey. Stop, stop... hey... Stop... look, I'm sorry. I don't know what you mean. Jay Garrick didn't come with us." Barry explained.

"Look, just keep tapping, please. We don't understand." Jesse pleaded.

"Please." Barry said but a moment later, Zoom sped in as their blood ran cold, while Zoom faced the man in the iron mask.

"Don't talk to them again." Zoom warned.

Barry glared as Zoom phased into his cell, choking him before letting go. "I'm gonna get out of here. And I'm gonna destroy you." Barry vowed.

Zoom roared, grabbing Barry by his throat. "All I need from you is your speed, Flash. And you only need to be barely alive for me to get it."

Zoom started to brutally beat Barry up as Jesse looked in horror. "Stop! Stop!" Zoom stopped and sped off as Barry fell down and Jesse looked him over. "Barry. Barry, are you OK?"

Barry panted out as he got up, groaning. "Yeah. I'm OK." He looked around, an idea forming in his mind. "Zoom just showed me how to get out of this thing."

Outside Central City

"You're sure this is the place?" Cisco asked as they walked down the woods.

"This is definitely the place." Harry said.

"You lost?" Killer Frost went out from the woods, with Harry aiming his gun and Patty and Allen yelping, with Patty clumsily reaching for her gun, aiming at Frost and Laurel stepped up in front of Allen and Patty protectively. "Or just back for more fun?"

"We just came here to talk." Harry said.

"Oh, really? Do you bring your little toys to every conversation you have?" Killer Frost mocked, seeing their weapons. "Or do you just want to see me burn again?"

"Or maybe I could just turn you deaf. I've never used my powers on a meta before." Laurel sneered.

"Tell us, where does Zoom keep his prisoners?" Harry demanded.

Killer Frost eyed Laurel and Cisco, amused. "You really don't know how to use your abilities, especially you, do you, breacher?"

"It's a work in progress, Elsa." Cisco said before trying another tactic. "Zoom killed the love of your life. This hurts, even for somebody with a heart as cold as yours."

"And you think that would make me turn on Zoom?" Killer Frost challenged.

"Enemy of my enemy is my friend, right?" Cisco asked as Laurel, Patty and Allen eyed him incredulously. "What... don't tell me it doesn't work like that over here."

"If I tell you, he'll kill me. But if I kill you and take you to him, I bet he'd be pretty pleased with me. Maybe even let me off my leash." Killer Frost charged her hands. "So take a wild guess. What do you think I'm gonna choose?"

Laurel unleashed her sonic scream, knocking Killer Frost down. Killer Frost was about to get up before Harry and Cisco aimed their weapons at her, while Laurel glared.

"I don't want to kill you, Frost, but I will do what I must." Laurel warned. "Tell us where's Zoom's hideout and we'll let you live."

Harry loaded his rifle. "Where is it?"

"If I tell you, he will kill me." Frost said.

Cisco scoffed. "He'll kill you anyway, Caitlin."

"Stop calling me that. It's not my name." Frost sneered.

"Yes, it is. You just don't want to hear it because it reminds you of someone you used to be. Trust me, I know that person very well." Cisco insisted.

"You don't know anything about me." Frost said coldly.

"I know the Caitlin Snow on my Earth. I know that when she loves someone, that person is her world. That person was Ronnie Raymond. And he died too." Cisco said pleadingly with an understanding look. "It devastated her, and I can see it's doing the same to you. Zoom took that." He gestured to Harry. "His daughter... my friend... he's gonna take them away from us, just like he took Ronnie from you." He leaned towards Frost. "Caitlin... all you have to do is tell us where he's keeping them. And then you'll never hear from us again, and you can go. Please."

Frost considered before getting up. "Fine. I'll show you where it is. But that's it."

"Uh, where are we going?" Allen asked.

"Ascension Cliffs." Frost said.

Zoom's lair

Barry attempted to phase through the glass but hit it as he groaned.

"Look, are you sure you want to keep doing that? You know, if Zoom catches you, he's gonna hurt you again." Jesse said.

Barry sighed, looking confused. "I don't understand why I can't phase through this."

"Well, your body would need to have the same resonance as the glass walls." Jesse pointed out.

"I should be going more than fast enough. It's something else." Barry said.

"Maybe you're resonating at a different frequency." Jesse said.

Barry nodded, that made sense. "Yeah, your Earth vibrates at a different frequency than mine. Same reason Cisco can't vibe."

"Is there any way to make up the difference?" Jesse wondered.

"Only if I can go faster." Barry said, trying to phase through again.

Cisco, Harry, Patty, Laurel, Allen and Frost neared the cliffs as they saw the cavern above them with a bridge.

"Wow, wow, wow." Harry said.

"We're going up there?" Allen demanded.

"That's where Zoom's lair is." Frost said.

"A place only a speedster could get to." Harry noted.

"There are like the Cliffs of Insanity." Cisco said.

"How are we supposed to get up there? That bridge can't hold us." Laurel said.

"I can make you something to climb on, darling." Frost offered.

"Climbing on ice. Well, when I said we need to exercise more, this wasn't what I had in mind." Patty said dryly as Frost was forming an ice structure for them to climb on until they got up and looked around the lair.

"Wow. This is… wow." Laurel noted. "Evil bad guy lair. Creepy."

"Barry? Barry?" Cisco looked around before laughing as he found Barry in his cell.

"Cisco?" Barry got up, looking in disbelief.

"Dude, we made it." Cisco assured.

"How did you find this place?" Barry demanded.

"Had some help." Cisco said, turning to Frost as Barry looked at her in surprise before Cisco gestured to Allen. "Don't even get me started on this guy." Allen waved his hand.

Harry rushed to Jesse as Barry was unable to believe his own eyes.

"Dr. Wells..." Barry trailed off.

Harry opened Jesse's cell and hugged her tightly as she returned the hug, sobbing. "I'm here. I'm here. Come on, let's get you out of here."

Harry tried to unshackle Jesse before turning to Frost. "Frost?"

"A little help?" Cisco asked

Frost raised her eyebrows and shrugged, shaking her head. "Not part of the deal."

"Frost!" Harry snapped.

"Hey, hey, hey. Bringing us up here wasn't part of the deal, either, but here you are. Something tells me you're not as cold as I thought you were." Cisco said.

"Maybe, maybe not." Frost shrugged before she undid Jesse's shackles and she turned to Barry, trying to freeze the glass.

"What's happening?" Patty asked.

"I don't know. I've never had this problem before." Frost said, confused.

"Carbyne." Harry realized. "It's some form of carbyne. This cell's made out of some form of carbyne. You'll never be able to freeze him out of there."

"Barry…" Laurel took a breath. "Stand back and brace yourself. This is gonna hurt."

"Wait, no, no! Laurel, don't! You could hurt him! There's no way he can outrun the blast!" Harry protested as he stepped up.

"Do you have a better idea?" Laurel snapped.

"You can't phase out of there?" Cisco asked.

Barry shook his head. "Just go, all right? Before Zoom comes back."

"We're not leaving you here." Cisco protested.

Barry panted out. "I can't get out of this cell. I've tried a lot. I'm not fast enough to phase through this. You got... just leave, all right? Just leave."

Allen stepped up, facing Barry, nearing the glass. "Do you know what we did to get here, Barry? We convinced her..." He gestured to Frost. "Killer Frost, to show us the way. Then we climbed some insanely steep cliffs outside on footholds made of ice. Ice! And all of us risked our lives, knowing Zoom was after us, to rescue Jesse... and you."

Barry just stared at his doppelganger, who sounded more convinced than ever.

"Now, I don't know you, and you don't know me, but I can tell you that today, I... I did things that I never thought possible, because I needed to prove to my girlfriend and to myself that I could." Allen took a breath. "Now, if I can do the impossible today, so can you. I'm just Barry Allen, but you're the Flash." Barry's eyes got wet. He never thought that he would have that kind of conviction in himself. "If you tell yourself you can phase out of there, you'll do it."

Barry smiled and prepared himself, while Allen nodded and they stepped aside. Barry vibrated himself until he was able to phase through the glass as they laughed.

"OK, let's go. Go, come on." Cisco said.

"Wait, wait! Hey, hey, hey! We're not leaving him." Barry said, turning to the man in iron mask.

"Barry, there's no time." Harry protested before Zoom sped in and Jesse screamed in horror.

"He's not going anywhere, and neither are any of you." Zoom said before turning to Frost. "Thank you for bringing them to me."

"You double-crossed us?" Cisco stared at Frost incredulously. "He killed Ronnie!"

"Guess my heart is as cold as you thought after all." Frost said indifferently.

"I can't believe you." Cisco glared at her. "Just so you know, you would be very disappointed in you right now."

Barry stepped up. "Zoom. Let them go."

"All you need is me and Barry." Harry said.

"You're right. I may not be able to kill you yet, but I can kill them." Zoom said, pointing to the rest before grabbing Jesse.

"No, no! No..." Jesse sobbed.

"I told you I'd kill you in front of your father." Zoom said.

"No! No!" Harry yelled.

"No..." Frost whispered before knocking Zoom down with beams of ice. "Get out of here." She fired more ice beams, subduing Zoom as they ran off.

"Caitlin…" Cisco stared.

"You were right. He killed Ronnie." Frost said.

"Thank you." Cisco nodded as they ran off.

"I'm not leaving without him." Barry pointed to the man in iron mask.

"Barry, there's no time. There's no time!" Harry protested.

"I can't hold him forever." Frost said.

Barry turned to the man in the iron mask, nearing his cell. "Hey, I'm coming back for you when this is over, all right?"

"Go!" Frost ordered.

"I'm coming back!" Barry promised as the man in the iron mask nodded before he sped off.

S.T.A.R. Labs, Earth-1

Jay and Joe were trying to keep the breach stable with Joe readjusting the stabilizer rings and flipping the switches in the Speed Cannon and Jay speeding around the breach until the breach opened.

S.T.A.R. Labs, Earth-2

"You need to get out of Central City, all right?" Barry ordered to Allen, Patty and Laurel. "Any place you think you'll be safe from Zoom."

"Yeah. I think we should visit your parents in Atlantis." Patty nodded, turning to Allen, who nodded too.

"Yeah, OK, good." Allen agreed.

"I have some friends in Starling City. They can help me lay low." Laurel said.

"Be careful, OK?" Patty said.

"Same to you both." Laurel said.

Barry turned to Allen. "You may not have been struck by lightning over here like I was, but today, you risked your life to save somebody you didn't even know. That's a hero, Barry. Thank you both." He then turned to Laurel. "Powers or not, you're always gonna be a hero. I'm glad to know that you've got good friends here, Laurel."

"Barry…" Laurel trailed off. "Is Ollie alive on your Earth?"

"Yeah, he is." Barry nodded.

"Tell him that I'll always love him." Laurel said.

"I will." Barry nodded before nearing Harry and Jesse. "Hey. You guys need to get someplace safe too. Where are you going?"

"The only place we can." Harry said, packing up.

"Dad, we can't just leave." Jesse protested.

"We have to, honey." Harry said.

"What, you want me to leave everything I have here?" Jesse demanded. "My friends, my family... I mean, my life."

Harry turned to her. "You don't have a life here anymore. Either do I. Zoom is too powerful. I can't stop him. And as long as he is here, he's gonna hunt us down until we're dead."

The alarm bleeped suddenly throughout the whole S.T.A.R. Labs.

"Wells, if you're coming with us, we have to go." Barry said.

S.T.A.R. Labs, Earth-1

Cisco and Jesse emerged from the breach. "Get ready to close the breach for good, Zoom's coming!" Cisco ordered.

S.T.A.R. Labs, Earth-2

"Forgetting someone, Flash?" Zoom gloated, holding Harry by his jacket.

"Let him go." Barry said.

"Close the breach." Harry choked out, while slowly reaching for a dart with speed-dampening serum. "Tell Jesse I love her."

"Tell her yourself." Barry said as Harry jammed the dart into Zoom's chest. Zoom groaned as Barry grabbed Harry and entered the breach.

S.T.A.R. Labs, Earth-1

"It shouldn't be taking this long." Cisco noted and a moment later, Barry and Harry emerged from the breach.

"Close it! Close it now!" Barry ordered and Jay threw the breach implosion device into the breach as it was closing.

"You're back!" Patty cheered.

"You did it! You made it!" Caitlin said as she and Patty hugged Barry tightly.

Jay neared the breach and turned to Caitlin as they smiled at each other, but much to their horror, Zoom's arm protruded suddenly from Jay's chest and pulled him into the breach before it closed, much to Caitlin's horror.

"No!" Caitlin exclaimed.

So, what do you guys think?
