Central City

Joe and the officers were in a cruiser, surrounded by Zoom's army before the Flash sped in, as the metahumans disappeared. The past few days had been tiring as they were trying to stop this metahuman apocalypse, or as the media called the invasion of Zoom's army, "the Metapocalypse". But that wouldn't slow the Flash down. With the help of the Flash, the Anti-Metahuman Task Force was able to fend off the metahumans from Earth-2 but it seemed that more and more kept coming.

"We usually take these guys down one at a time, not one hundred at a time." Barry said, as he entered the Cortex with Patty.

"I'm surprised you don't seem overwhelmed." Patty noted.

"I know we can do it." Barry said. "I know from the Speed Force that the universe is with us, not Zoom. And if the universe is with us, how could we possibly lose?" He looked at everyone, smiling. "Right, guys?"

"Yeah, yeah, right." Jesse nodded.

Barry walked off before anyone could say anything more as they stared.

"OK, I'm gonna say it. Um, we don't think he's being just a little too..." Cisco trailed off.

"…overconfident?" Patty finished and Cisco nodded.

"Whatever happened to him in the Speed Force, he believes he's invincible now." Caitlin said.

"That's just going to get him killed, if he's not careful." Wally noted.

"Somebody needs to talk to him before letting his guard down gets him hurt or worse." Harry said.

Central City

In front of Mercury Labs, a tall muscular Afro-American pulled out his ring as the building was surrounded by some black energy, causing for it to crumble.

Dr. McGee tried to run as the Flash sped in, rescuing the scientists and getting them out to safety before McGee turned to the Flash. "Thank you, Mr. Allen." The Flash looked at her in shock. "I'm not stupid." McGee smiled.

Unknowing to them, an Afro-American with a helmet was walking down the street, on his finger glowing a black ring.

Later, S.T.A.R. Labs

"So how did you know?" Barry asked as they were in the Cortex.

"Your real identity?" McGee asked.

"Yeah." Barry nodded.

McGee chuckled. "Come on, Barry, I'm a scientist. We're paid to be perceptive. And you're always a little too well informed when things go pear-shaped in this city." She turned to Henry, offering her hand. "But I don't believe we've ever met before. Dr. Christina McGee."

"Dr. Henry Allen. I'm Barry's father." Henry shook his hand with McGee.

"OK, now that the cat's out of the bag, did you happen to see who it was that caused your building to collapse?" Barry asked.

"It was some… black energy surrounding the building. Right before the building went down and then it all just happened so fast." McGee said.

"Maybe the security cameras caught something?" Caitlin said.

"Can we access them?" Henry asked.

"Mercury Labs does have a Crash-Survivable Memory Unit." McGee nodded.

"A what?" Barry asked, confused.

"Virtually, a black box for buildings. It will have stored all the security footage right up until the building collapsed." McGee explained.

"OK, great, I'll go find it." Barry said.

"It can't have been a coincidence that a metahuman tried to tear the building down. Anytime they've targeted Mercury Labs in the past, they've always had a specific reason for it." Patty noted.

"Yeah, someone's after something." Cisco nodded.

"Yes, and that someone is probably Zoom." Caitlin added.

"There may be one more possibility. A few months ago, I saw Harrison Wells running out of my facility. I know it sounds crazy, but I'm certain it was him." McGee said as everyone shifted uneasily. "Is there any way he could have anything to do with this?"

"A few months ago? Sure." Harry said as he entered and McGee stared in shock upon seeing him. "Now? No."

"Yeah, there are a few more things that we could catch you up on, Dr. McGee." Barry said awkwardly.

A little bit later, Barry returned with the Crash-Survivable Memory Unit, handing it to McGee. "Is this it?"

"That's the one." McGee nodded as Barry handed it to them.

"All right, great. Dad, Dr. McGee, Cisco. Why don't you guys crack this open, see what you can find?" Barry asked.

"Sure." Henry nodded.

"Wait, Barry. When you mentioned black energy, this jogged my memory." Harry said as he opened his watch and sighed. "You're not going to like watching it." Harry typed away as on the screen appeared a picture of a muscular Afro-American, who was in black coat. "Meet Earth-2 John Diggle."

"Earth-2 Dig did this?" Cisco demanded.

"You know his doppelganger?" Henry asked.

"He was a friend." Patty said.

"He was killed few weeks ago. You read about the Ghosts?" Barry asked as Henry nodded. "One of them was his brother. He betrayed Dig and Damien Darhk had him killed."

"Well, on my Earth, the Diggle brothers were mercenaries. Thieves. Assassins. Spies. You name it. When the particle accelerator exploded, it irradiated this… prototype energy ring they had stolen from Earth-2 Cadmus Labs. Competitors of S.T.A.R. Labs. It helps generate energy fields at the wielder's whim." Harry explained, but then saw their confused looks. "Imagine you want a hammer. That ring forms an energy hammer out of thin air. Imagine you want an armor to protect you. That ring creates an energy field that protects your body."

"When the building fell down, I saw the black energy surround it." Barry remembered.

"He calls himself 'Black Hand', whatever he wants, the ring can make it come true." Harry said.

"All Barry needs to do is separate him from the ring." Patty said.

"Barry, don't be fooled by his appearance. He's stronger than he seems to be." Harry said.

"All right, I'm gonna go see if Joe needs any help in the streets. Everybody cool here?" Barry asked, about to leave. "Should be a piece of cake, right?"

They all exchanged concerned looks before Henry followed Barry down the hall. "Hey, slugger!"

"Hey." Barry said, turning to him.

"Can I talk to you for a minute?" Henry asked.

"Yeah, sure. What's up?" Barry asked.

"Well, I know you said that what happened to you in the Speed Force changed the way you see things, but you seem very optimistic, you know, with a lot of metahumans running around tearing up the city. What, did you see the future in there?" Henry said.

Barry laughed. "No... um... not this time. No... I... look... What I was shown in the Speed Force didn't just change my mind, it changed me. I don't know... what you're seeing as optimism is, for the first time, I'm just not afraid anymore."

"Great, that's..." Henry paused as Barry looked confused. "But... You know you still have to be careful, right?"

"What do you mean?" Barry asked.

"Well..." Henry was not sure, what to say.

Barry sighed as he turned around, leaving. "I don't... why are you trying to take something from me that I fought so hard to get to?"

"Barry!" Henry called out.

"I... you... you don't know everything that I've been through, Dad." Barry said, turning to Henry. "You haven't been here long enough to know." He paused, realizing his mistake as Henry looed hurt. "I didn't mean... I'm sorry. I don't know why I said that."

"I think I do. Hadn't been around." Henry said, understanding as he neared Barry. "Teach you how to drive or take you to look at colleges. But I've done everything in my power to know who you are. Barry, I don't want to take anything from you. I believe in you." He placed his hand on Barry's chest. "This isn't about my not believing in you."

"I know that. And I'm fine. OK?" Barry assured. "Thank you, thank you very much for worrying about me. I love you. But I'm fine."

An alert went off as Patty neared Barry. "Barry. It's CCPD."

CCPD

Barry sped into the lab, where he saw Zoom eying the table of evidence Barry had on his mother's murder. "You and I are not as dissimilar as you think, Barry. My father was also convicted of murdering my mother, unjustly, few years ago. All evidence was talking against my father but I knew he didn't do it. No one could prove the otherwise until after the trial. When they sent my father away, the real killer later snuck into prison and killed him too and was gunned down, when attempting to escape. And do you know, who failed to prove his innocence?" Zoom turned his head and glared at Barry. "Barry. Allen."

"That's why you hate me so much? Why not just kill me?" Barry asked, seeing Eobard Thawne through Zoom's eyes.

"Like I said, the more connections you have, the easier it'll be for me to break you. And how does it feel, knowing that the people you love, those who look like them, destroy everything you care about?" Zoom gloated.

"What did you do?" Barry asked.

Barry saw a building covered in black energy, crumbling down.

"I've broken you before. I will break you again. How many lives you can save, before they'll see you're no hero. Once I'm done, they'll see you for the fraud you are. Like I told you…" Zoom put on his demonic voice. "…I am the fastest man alive, Barry."

"This isn't over, Zolomon." Barry sneered before he sped off.

Central City

The Flash knocked Black Hand down, who got up as Barry stared at the face of the doppelganger of his former friend. "Well… I was wondering when you would show up." The man said, wearing John Diggle's face.

"I'm not going to let you hurt any more people, Dig. Give it up." The Flash said.

"Sorry. Can't do that." Black Hand said.

Barry attempted to rush at him but Black Hand formed a ramp on which the Flash accidentally ran before flying up and then was knocked away as he rolled down the road as Black Hand used his ring. Barry was then trapped in some energy ball but phased through and rushed at Black Hand as they exchanged blows. Barry was about to disarm him of his ring but Black Hand formed some blast of energy, knocking Barry down.

"Seriously, how is it, that Atom Smasher, Sand Demon, Dr. Light and the others have failed to kill you?" Black Hand gloated as he formed a giant anvil, about to crush Barry. "All I need to do is—"

Suddenly, a sonic scream knocked Black Hand away as the anvil disappeared. Barry recovered and stared in disbelief as he looked at the blonde woman in black dress.

"What's the matter? You don't like the Siren's call?" Earth-2 Laurel smirked.

This felt like a good stopping point.

Funny thing about the interactions between McGee and Henry in this episode. In The Flash series from 1990, with John Wesley Shipp as Barry Allen (The Flash), Amanda Pays actually played Dr. Tina McGee too in the show as one of the main characters and love interest of Barry and was basically that show's version of Caitlin and Cisco with her being Barry's doctor and providing him experimental inventions to help him, explaining the attraction between Henry and McGee in the CW The Flash show.

In this story, Diggle is the one, who had died, instead of Laurel. And Earth-2 Diggle has a special ring like Lanterns, which explains his abilities. Hope you like his backstory. Speaking of which, considering his crap, especially in the Arrow finale, Earth-1 Diggle is unworthy of wielding the Green Lantern ring.

Frankly, killing off Laurel was one of the biggest mistakes Guggenheim and Mericle had done, and insult to injury was Laurel basically giving blessing to Olicity on her deathbed. Felicity being the love of Oliver's life is complete load of crap, considering how awfully she treated Oliver in Seasons 3-4 and despite that Oliver/Felicity was fixed more or less with the drama toned down and Felicity treating Oliver better in Seasons 6-7, save for some understandable exceptions, the damage had already been done.

While I wasn't much of a fan of Laurel, due to how her character was mishandled in Seasons 1-3 of Arrow, with her being a bitch to Oliver at first, then her drug addict arc in Season 2 and freaking out on Oliver and Sara, when Sara came back and then her Black Canary arc in Season 3, which was lazily written and gave Laurel an annoying ego boost and Season 4 with Laurel having a stick up her ass with bringing Sara back to life, I still liked her more than Felicity, plus, considering the comic books with Green Arrow and the Black Canary, it was a big mistake to kill Laurel off.

While I wasn't much of a fan of Thea in Season 3, in Season 4, asides from the mess with Sara and Lazarus Pit, she was actually one of the better characters, but killing her off right after they used the pit on her in the previous season, felt stupid too.

Felicity probably would have been too predictable, even though it would make sense. Diggle or Quentin too, due to Andy betraying them and Quentin, frankly, had reached his full potential in Season 4 of Arrow and it would be no surprise if Darhk had killed him too.

And Caitlin's line "We loved Laurel." honestly made no sense at all. In real life, Danielle Panabaker and Katie Cassidy have been close friends for years, they were even roommates at one point but in Arrowverse, Laurel and Team Flash barely knew each other and it was more of a fan-based shoutout to appease the fans.

Speaking of which, The Flash 2x22 shows that Katie isn't as good actress as some people would want to believe. I mean, I like Katie Cassidy but the acting and the lines Black Siren had in this episode, were just terrible and cringeworthy.

Hope you like Earth-2 Laurel helping Barry out now.

The next chapter is going to diverge from canon, with Team Flash's final battle against Zoom and his army, since, let's face it, Zoom's endgame in the show made no sense at all. Zoom spent the entire season trying to conquer Earth-1 and other Earths later and suddenly, he decides to destroy all Earths at once, asides from Earth-1. And it's quite sad, when you realize that Anti-Monitor in Crisis on Infinite Earths becomes much less threatening, when Zoom could do what Anti-Monitor wanted, just by charging up his own machine.

So, what do you guys think?
