Night

"So now Devoe can swap bodies?" Cisco asked as they all stood in the cortex, staring at Allen and Barry in disbelief.

"The way Devoe described it; I wouldn't call it a body swap. It's more like Devoe…took over Dominic's body," Barry said, trying to put it into words.

"Barry's right," Caitlin said as she returned from running the autopsy. "The brain stopped functioning before the heart. He was braindead before he died. Whatever Devoe did, it somehow transferred his consciousness into Dominic's body."

"How is that even possible?" Ralph asked stunned.

"Possibility is only limited by the imagination. And Devoe doesn't seem to have a limit to his," Harry noted grimly.

"Thank you for getting Barry out of there," Joe said as he looked over at Allen grateful. "Things could have gone a lot worse if you hadn't."

"Well, the blood is still going to come back as Devoe's but with an alibi, there's not much that can be done," Allen said with a nod.

"You were fast though, even faster than me," Barry noted with a hint of envy. "How are you faster than me?"

"It's something new, something that happened recently," Allen said vaguely as he thought of holding Mjolnir. "It made me faster, a lot faster."

It was something they had discovered a few days before he and Wanda had left for their vacation. They had breached back to Earth-66 so Caitlin could run some test. Best as she could tell, holding Mjolnir and wielding Thor's power had caused him to absorb the energy of the Asgardian weapon, increasing his speed and healing factor.

Everyone eyed him, clearly sensing he was holding something back. But now wasn't the time for interrogations.

"So what do we do now? Devoe is in the wind," Ralph asked.

"Not exactly," Allen said as they all turned back to him. "At the party, I put a tracer on him."

"What, when?" Cisco asked as they stared at him stunned.

"You clapped him on the shoulder," Ralph remembered and Allen nodded.

"Did you know he was Devoe?" Iris demanded but Allen shook his head.

"No, but something about him felt…off. He was different somehow. I hoped I was being paranoid, but it never hurts to be careful," Allen explained.

"Devoe is too smart to fall for that," Harry noted.

"Which is why this isn't an ordinary tracer," Allen said as he pulled out a small device, a grey spec no larger than a thumb. "This tracer injects Nanites into the blood stream, painlessly and undetectable. For the next forty hours, we can track him wherever he goes."

"Man, you're like Barry and Oliver rolled into one," Cisco said in awe and Allen smiled tightly.

"Well, after everything I've seen the last three years, a lot of Oliver's decisions don't look so crazy," Allen said as he pocketed the device. "The point is we can track him. So, who's up to taking Devoe down?"

"So, this Monitor guy sent Barry into a different timeline where he never met us?" Sam asked, trying to wrap his head around it.

"Just when I thought my life was crazy enough," Cisco said as he plopped down onto the couch with a sigh.

"So we know where he is, but can we get him back?" Steve questioned with a glance towards Strange.

"It's possible," Strange admitted. "Using the Time Stone, theoretically, I could view these alternate timelines and find which one Barry is in."

"So why do you look like it won't be that easy?" Natasha inquired as she crossed her arms.

"Because just as there are infinite earths, there are infinite timelines, like the one Freya and Fate traveled back from. It will take some time for me to discover which one Barry is in," Strange said but they still felt like he was holding something back.

"What aren't you telling us?" Clint demanded.

"Honest, I'm not so sure I should try and find him," Strange said after several moments, to their disbelief. "Mar Novu went to a lot of trouble to put Barry in this alternate timeline. I imagine he won't let Barry leave until he believes that Barry has passed his test."

"I don't care," Wanda hissed, her eyes flashing red.

"Your Monitor buddy can try as hard as he wants, but we're going to find Barry, with or without your help," Cisco said as he got to his feet. "Are you gonna help us or not?"

Strange looked around and saw the same determination was in the eyes of everyone else.

"I will help you," Strange final gave in. "If only to make sure you don't destroy the timeline trying to find him. But it will take me some time to locate the timeline Barry has been placed in."

"Well we don't have anywhere to be. Get started," Clint said with a 'get going' gesture.

Night

"How do we know that Devoe didn't read your mind and isn't waiting for you?" Iris demanded.

"Because you can't read the mind of a Speedster," Allen said, surprising them. "I checked, one of the Avengers is a mind reader. Our minds run more than ten times faster than a normal human's. A mind reader can't keep up with it; the most they'll get is a few words or images here and there."

"Well, that's something at least. We have one advantage," Harry noted.

Suddenly, Barry slumped against the computer desk, using his hands to support himself. He let out a pained grunt as the all looked at him concerned.

"Barry?" Iris questioned as she placed a hand on his shoulder. "What's wrong?"

"Run," Barry said in a choked gasp.

Suddenly, Barry's arm flew out and struck Iris across the face. She went down, holding her face as everyone stared shocked. Before they could process what had just happened, Barry sped over, grabbed Harry by the throat, and threw him into the wall. Barry turned to face the others and they noticed a blank, emotionless, almost robotic look on his face and eyes.

"Barry?" Joe questioned but Barry didn't respond.

"Stay back," Allen said as he stepped in front of them. "Devoe, he did something to Barry when he had him. I recognize the look of someone being controlled."

"We need to get him into the pipeline," Caitlin said, her eyes flashing as Killer Frost took over.

"He's not gonna let that happen," Allen said, taking off his jacket and throwing it to the floor. "Leave him to me. You just have a cell ready."

Allen and Barry then rushed each other, meeting in a high speed tackle. The pair sped through the building before stopping in the Speed Lab. Barry slugged Allen but Allen shrugged it off, grabbing Barry and throwing him down to the floor. Barry got right back up, staring at Allen with that same robotic look on his face.

"I don't want to hurt you Barry, but I will if I have to," Allen said firmly.

Barry simply rushed him at super speed. Allen held his ground, pushing back as Barry tackled him. They continued to speed all throughout the building as they traded blows. They made it into the longue and sped out the balcony. The glass shattered as they went through it and then they were in midair, trading blows. Allen blocked Barry's strike with one hand as he rotates his free arm, creating a small cyclone. The cyclone slowed their fall and, at the right level, Allen sent a powerful kick to Barry's chest. Barry was sent flying, hitting the Star Labs sign and going right through it. He hit the side of the building and slumped to the ground. Allen reached the ground, letting out a sigh of relief before, to his shock, Barry got back to his feet.

"You're tougher than I thought," Allen muttered. "I'm gonna have to stop going easy on you."

The two rushed each other and exchanged a high speed punch. They speed around in a circle, exchanging blows and Allen had a flashback of doing this same thing with Thawne in front of Star Labs several years ago, when he was first starting out.

They took off into the sky in a blur of movement and landed on the roof. They traded some more blows at high speed before Allen sent a powerful kick to Barry's chest. Barry was sent flying into the tower behind him and, before he could recover, Allen was there, punching him at high speed. Allen waited until he was sure Barry was out cold before he stopped. Barry slumped forward and caught Barry, wincing as he saw Barry's bloodied face.

Late afternoon

For the last hour and a half, everyone watched as Strange meditated in midair, holding the Time Stone as he scanned alternate timelines for Barry. As they watched, Clint walked up next to Wanda.

"Hey, are you okay? I know it can't have been easy…seeing him," Clint trailed off.

"It wasn't," Wanda admitted. "But, in a weird way…it helped. I always wondered…what happened to him, if he was okay. Now I know he is. I know he's off doing important work, whatever it is. And I'm proud of him."

"I'm sure he's proud of you to," Clint assured her as he placed a hand on Wanda's shoulder.

"I found him," Strange said as his eyes snapped open.

Night

Iris, a bag of ice on her face, watched with the others as Caitlin and Cisco presented their findings after doing an x-ray of Barry.

"You see this little spec at the base of his skull?" Caitlin asked as she gestured to a small, grey dot at the neck area.

"What is it?" Joe asked worriedly.

"My best guess, Devoe implanted it in Barry at some point while he had him in his evil lair," Cisco said.

"How do we get it out?" Ralph asked and Caitlin and Cisco exchanged a look.

"It's not that simple Ralph. To try and get it out surgically would be very risky. Not to mention Barry's healing factor," Caitlin explained.

"So we don't remove it surgically," Allen said as they glanced over at him. "I'll phase through and get it out myself."

"It's possible but...there are risks," Caitlin said doubtfully.

"Well, the only other option is to leave it in so Devoe can control Barry whenever he wants," Allen argued and it was silent for a moment.

"He's right," Harry said and they all looked at him. "The only solution is for Allen to take it out."

"Do it," Joe said and Allen nodded.

"Why would Devoe put this in Barry anyway? From the sounds of it, he's an egotist who thinks we're all ants," Ralph pointed out.

"I think it's because of me," Allen said and they all looked over at him. "I'm an unknown variable, Devoe's plan didn't account for me. He put this in Barry's head in order to make Barry kill me."

As everyone absorbed this, suddenly, an orange circle opened up in the corner of the room. As everyone else jumped back, Allen smiled in relief as Strange stepped out.

"Mr. Allen," Strange greeted.

"Dr. Strange," Allen greeted politely as Team Flash looked at him confused. "I have never been so happy to see you."

"So uh, who's your friend?" Cisco asked as they waited for Allen to answer.

"Stephen Strange, he's from the same earth as The Avengers," Allen explained before turning to Strange. "I assume Cisco headed to Earth-66 to find you?"

"Not just him," Strange said as Wanda stepped out of the portal next to him.

"Barry," Wanda said in relief upon seeing him.

For a moment, time seemed to stand still as Allen stared at her. Then, he sped over and, to the shock of Team Flash, grabbed his wife and kissed her fiercely. As they saw this, Joe and Caitlin quickly put together that this was Wanda, Allen's wife. Glancing over at Iris' shocked face, Joe knew she wouldn't take this well.

"I was beginning to think I'd never see you again," Allen said breathlessly as he pulled back, drinking her in after so many wees without seeing her.

"You can't get rid of me that easy," Wanda said with a smile.

"Um, someone want to explain what's going on?" Cisco said.

Allen let out a breath, knowing he'd have to explain this. He hadn't wanted to deal with iris' reaction, but it didn't look like he had a choice.

"Everyone, this is Wanda…my wife," Allen said as he turned around to face four stunned people.
