His eyes snap open to extremely bright and harsh light that forces him to close them shut again.

"Guys, he's awake!" Someone yells from his side. Is that Iris? Sounds like her. But what's Iris doing in the Arrow Cave? (He'd spent enough time with Kara, Barry, Cisco and Felicity so it rubbed off on him.)

"Oh thank God," someone else (Cisco?) says.

He opens his eyes again, slower this time to allow them to adjust, only to have them widen at the realization that he was in S.T.A.R. Labs, specifically in the makeshift medical wing. He could recognize the place by the walls alone, having been there too many times waiting on Barry to wake up, other times he'd be waiting on Kara, and for the rest of the while, he'd be waiting on both. Kara and Barry may have been given superpowers, but not getting themselves knocked out isn't one of them.

But he's never actually had to wake up in it before.

He tries to get up, but two things stop him: Caitlin's steady and firm hand forcing back down as she berates him, and the sudden sharp pain that thunders in his head.

He doesn't remember getting his head hit in the past twenty-four hours, so why does it feel like someone had left a jackhammer in his skull?

Well, he wouldn't be the best judge. If he had been hit in the head, then he couldn't trust his memories, recent as they may seem.

"I swear, Barry, if you try to get up one more time I'll—"

Caitlin isn't able to finish her threat because he cuts her off worriedly. "Barry?" Last he checked, Barry's not in the room. That's... disconcerting. He does a quick survey around the room again just to absolutely make sure. "Where is he?" His eyebrows furrows; is it just him or does he sound different?

"Uh oh, this is not good." Cisco steps closer, concerned. "How hard did that meta hit you?" Okay, so he had been hit. Had he been helping Barry with a meta problem? Is that why he's in Central City? Did he come alone? His team is nowhere to be found, so he must've come alone.

"I'm—" He stops himself when he lifts his hand and sees red.

A red glove.

He quickly looks down at his body and—

He's wearing the Flash suit.

He groans as he throws himself back down onto the pillows. "You have got to be kidding me."

He flinches as he quickly puts his hands up.

"I'm giving you ten seconds," Kara's sister says in a low, dangerous tone that would always scare the bejesus out of him. "Who are you and what have you done to my sister?"

Of course this had to happen. Of course he just had to switch with Kara and deal with her incredibly terrifying sister. (Why couldn't it have been Oliver?! At least then he'd be able to see Felicity.)

"I don't know!" He stutters truthfully. "I just woke up in some abandoned alley and before I knew it, I was flying and I broke a house and I didn't mean it, I swear, and I have no idea where Kara is, I swear I didn't hurt her, god, I'd never hurt her, not intentionally—not that I have or will because I love her and I'm pretty sure she alone can kick my ass to the next Earth and not to mention Ollie—"

Alex lowers her gun. "Barry?"

He smiles excitedly, but he doesn't dare put his hands down. "Yeah!"

She shakes her head slightly in amusement. "God, you're... exactly like her."

"You are not Oliver."

"Yeah, no. Sorry. Um, I have no idea how I'm in this Earth right now, much less in Ollie's body, so..."

"This Earth? Wait... Kara?"

"Hey, Felicity."
