The Flash is owned by The CW.

When Barry runs from 2024, he's devastated. He hadn't kept his promise to Iris, he wasn't there for Joe. He doesn't figure out how to stop Savitar until four years after Iris's death. He even gave up being the Flash. Cisco lost his hands, and now, they're made of metal.

Caitlin is locked up in Iron Heights, and Julian works there. Wally is in a catatonic state, and worst of all, he still doesn't know who Savitar is. Barry was broken, after having lived through that future, and he can't hold on much longer.

Slowly, he races down to the time vault, locking himself inside.

"You're back, Mr. Allen." Gideon greets.

"Goodbye, Gideon." Barry greets, and that's when he presses his hand to his chest, vibrating until his heart stops.

"Mr. Allen? Mr. Allen? Oh, my God, what did you do Mr. Allen?" Gideon panics, and that's when she sets off a panic alarm. Julian, Cisco, Wally, Joe, and Iris were in the main room of Star Labs, when they heard the panic alarm.

"What the hell?" Joe asks with confusion.

"It's coming from the time vault," Cisco calls, and that's when he goes down there. When he gets there, Gideon shuts off the alarm, and that's when Cisco realizes that Barry was on the floor. Also, he wasn't moving.

"Barry?" He asks with concern, and that's when he notices how unnaturally still Barry's chest was. Shit, Barry isn't breathing.

"Somebody help!" He screams, and that's when Julian runs to the time vault.

"What, what, what happened, what happened?" Julian panics, running into the room.

"I dunno, he just stopped breathing!" Cisco panics, and that's when he starts compressions. Caitlin had taught them all how to do CPR, but Cisco never wanted to have to do it on a friend. Julian just stood there, frozen in shock as he watches Cisco try to revive the speedster.

"Allen, please. Don't do this mate." Julian pleads. He'd already watched Caitlin die, he can't watch Barry die too. When Barry still wasn't breathing, Cisco switched to rescue breathing.

"Damn it Allen, don't you die on me too! Please don't die." Julian sobs, watching as Cisco continues to try to revive Barry. When Barry still wasn't breathing, Cisco continued the chest compressions.

"No, no. Come on, mate!" Julian pleads. Eventually, Barry gasps for air, and that's when he looks up to see Cisco's concerned face looking up at him.

"Don't ever do that again, Mr. Allen." Gideon scolds.

"Thank God." Julian sighs with relief, and that's when Cisco helps Barry up from the floor. When Cisco looks into Barry's eyes, he couldn't see the light that had once been in his friend's eyes. Whatever happened in 2024 had broken Barry, and Cisco wasn't sure if he could get him back this time.

"Allen?" Julian asks with concern, as he realizes that he hadn't spoken since Cisco got him breathing again. Why? Why did you save me? Barry wants to ask, but he doesn't.

"Barry. Let's get you out of here, okay?" Cisco calls, gently placing his hand on Barry's shoulder as he coaxes him into the main room of Star Labs.

"Barry." Iris calls, and that's when Barry looks at her. As Barry looks at Iris, the memory of seeing her grave taunts him. "Here lies Iris West. A wife, a daughter, a friend.".

"What did you see mate?" Julian asks. He needs to know, he needs to know what he saw. Needs to know how to help him, please Allen.

"Barry, please." Wally calls, trying to get him to speak. "What happened to him?" Past Barry asks, referring to Wally.

"Iris died, and it sent him into this rage, and, uh, he went after Savitar alone one night. Joe found him, the next day, with a shattered spine. We don't know what he saw that night, but he's been like this ever since." Cisco tells him. Barry couldn't shake the image of a catatonic Wally.

"Bar, please." Joe tries. "I wasn't there for you?" Past Barry had asked. Seeing Joe being so hateful toward him broke him.

"BA." HR tries. HR was the only person that was happy in 2024, that much Past Barry could see.

"Let's take him to our place. Maybe he'd feel better in his old room." Wally offers, and that's when he puts his hand on Barry's arm.

"You think you can run?" He asks. Barry stays still. No, I can't.

"I'll take that, as a no. Come on, I got you." Wally states, gently placing Barry over his shoulders.

"You ready?" Wally asks. Still, he doesn't speak.

"Hold on tight, okay?" Wally instructs, and so, Barry does. Within a matter of minutes, he raced him inside Joe's home, and that's when he helps him stand on the floor.

Barry slowly blinks, taking in his surroundings. Wally had carried him here, and Joe doesn't hate him? When the hell, was he? This wasn't 2024, where he had trapped his past self.

"Why did you trap me here? I need to get back to 2017!" Past Barry demands.

"Because you will always be way better than me." Barry tells him.

"Please! Don't do this!" Past Barry pleads.

"I'm sorry Barry." Barry sighs, vibrating Past's Barry's arm, as he forced Cisco's device inside him. This would ensure that Past Barry couldn't leave 2024, and he could be there for them, better than he had. Without that resonance field, he knew that Past Barry couldn't get back.

"Are you coming?" Wally asks, and that's when Barry followed him. When he trapped Past Barry, he made sure to cut his hair to match his, and that's when he runs, wanting to go anywhere, but 2024. The problem was, that he didn't know what year he was in, and so he couldn't risk speaking until he knows what year it is, and how old he's supposed to be, so he doesn't. Slowly, he walks in the room that he was staying in.

He didn't know what year this was, so he couldn't use his speed until he knew how fast, or slow, he was supposed to be.

"We kept your old room the same, just in case." Wally informs. It was odd, not having Joe hate him, and it was odd to see Wally up and around.

"You dropped this, by the way." Wally greets, handing him what was presumably, Past Barry's phone. Thanks. Barry wanted to say, but he didn't.

"Anyway, I'll be right down the hall, if you need me." Wally informs, and that's when Wally leaves the room, finally giving Barry some privacy. Slowly, Barry looks at the date on the phone, wanting some answers on when he was. Okay, so he was in 2017, from before Iris left. Wait, that means that he would have to force himself to run eight times slower if he didn't want to draw suspicion. Great, just great.
