A/N: So... Hi! *dodges pitchforks and rotten fruit* I'm sorry for taking so long. My muse abandoned me and it's been slow going especially with LIFE happening. Anyone who loves in the UK will understand the pain of UCAS. Anyone who doesn't live in the UK... Just university applications.

I can't guarantee when the next update will be, it might be soon... Or it might not be. But it might have to wait til after mocks (i'm studying Maths, Physics and Chemistry. And yes, I know i'm crazy). So... Because everything's going kinda slowly, I'm gonna break this into chapters rather than one looooong thing because

a) They take ages to write

b) I don't have that kind of time. Such is life

Anyway, I hope everyone had a great Christmas and have a happy New Year!

Barry looked at the new device that Cisco had fitted on his arm incredulously. He touched a hand to his comms, uncertainty colouring his voice as he spoke to the guys upstairs.

"Cisco... Are you completely sure about this?" Up in the Core, Cisco swung around to face the computers, tapping commands into the programme and a lollipop hanging out his mouth. Caitlin and Dr Wells were sitting up there with him, monitoring the various readings from Barry's suit and the device. They were both preparing for another case of 'patch up Barry'. Their favourite activity whenever Cisco unveiled a new bit of tech for the speedster. They even took bets on how long it would be til Cisco finally admitted defeat. So far they were tying, and they'd decided that the winner of this bet would have to give up the customary $20 as well as buying coffee for the other for 2 weeks. Neither of them wanted to lose considering exactly how much coffee played a part in their lives these days, what with dealing with Metahumans every other day.

"Yeah! Completely sure." Caitlin and Dr Wells glanced at each other, Caitlin raising an eyebrow (considering that she was betting that Barry, on a pain scale of 1-10 achieved between 7-10, she was really hoping- in a nice way- that Barry got hurt reasonably badly. Looking at the joy on Cisco's face, she was forced to believe that unfortunately, she was going to win). There was silence from Barry.

"Uh huh."

"Oh come on man! Don't you trust me and my amazingly named gadgets?"

"Cisco. I really hope I don't need to remind you exactly how many of your gadgets have knocked me out or broken my bones?"

"You heal fast. You'll live." Caitlin leaned over to Dr Wells.

"Do you think we need to remind him that if Barry wasn't who he was he would most likely be dead twice over?," she whispered to him. Dr Wells smiled.

"I really don't think now is the time, Dr Snow."

"Guys. I can hear you. Way to build up my confidence." Caitlin winced as Dr Wells just shrugged and got back to work. "Anyway, can we hurry this up? I've got, uh, somewhere to be tonight."

"Oh... Where are you going?," asked Caitlin as she ran the final checks. Barry sighed as he paced down in the cortex where they were running this test. Read 'trying to hurt Barry with a new torture device'. He really hoped to avoid this topic.

"High school reunion."

"I thought that you were, well..." Cisco paused awkwardly, remembering Tony.

"Yeah, well I moved to Paris for a year then started at a prep school for the rest of high school. It's our 7 year reunion tonight and I don't want to miss it." Dr Wells raised an eyebrow slightly smirking. Cisco just laughed.

"Seriously? You were a prep boy?! Ha! Nice one Barry."

"Cisco?"

"Yeah?"

"I was a prep boy genius. Live with it." There was an awkward pause.

"Right. Well... The device is all set up now. You are clear to go." Barry rolled his eyes as he got ready to run. His friends and mentor really did not need to know about his alter ego. Or his accidental time travelling. Where he'd met his past self and then changed a load of stuff. But hey, he'd neutralised the possibility of anything bad happening like it usually did when he time travelled (admittedly he'd only done one proper jump which didn't involve meeting his past self. Seriously though, what was up with that?) by wiping everyone's minds clean with a Men in Black type device. Thank God Cisco hadn't gone looking for it yet. He'd accidently broken it when he landed back in 2015 (read he had no idea where it was and maybe Cisco had lost it), and really was not looking forward to explaining anything about this to these guys. But then again, knowing his luck, something was probably going to happen that meant that they were going to find out.

He set off at a steady pace of 300mph, zooming around the broken particle accelerator (for which the hole had now been patched up. Caitlin and Cisco were getting tired of continuous birds and bugs getting into Star Labs simply because of their unexpected window).
He really hoped nothing went wrong. Heh, wrong.

Up in the cortex, the others were sitting and reading the results on the screen.

"Blood pressure, sugar and oxygen levels, brain activity and everything else seems normal," commented Dr Wells. Cisco nodded and was about to tell Barry to step on the gas when a warning sign appeared on Caitlin's screen.

"Uh Dr Wells?," Caitlin said tapping on it and reading the information. "We've got a thunderstorm brewing directly over Central City. If lightning starts coming down we might have to hold off this experiment. I really don't want another situation with Barry and lightning." Dr Wells sighed.

"Ok. If it gets any worse we'll call it off." He set a few parameters on his own screen before wheeling his chair backwards towards the door.

"Dr Wells? Where are you going?," asked Cisco curiously.

"To empty my bladder," came Dr Wells' reply as he disappeared around the corner. Caitlin glanced at Cisco.

"Too much information," she commented. Cisco nodded in agreement.

"So guys, when is anything actually going to start happening?," Barry's voice sounded over the comm system. "And can someone please explain to me again what's going to be happening?"

"Well, the funky gadget on your arm is going to measure your energy readout in the form of your lightning and then it will also hopefully-"

"Hopefully?!"

"- loop it back around into your system so you can go faster. And hopefully defeat the Reverse Flash." The sound of rushing wind came over the comms.

"Neither of you guys have said anything to him have you?"

"No Barry."

"As much as I disagree with this, I haven't either," agreed Caitlin sighing.

"Alrighty then," said Cisco, flipping a switch. "Let's get this show on the road!"

Barry felt a tingle in his arm that very quickly spread to all over his body. He risked a quick glance at the device (he did not want another blowing up situation) but it seemed to be fine.

"It looks like it's working, Cisco!," Barry called over the comms. He pushed forward, grinning as he ran. When he did run, he felt like he could let go of the past and his responsibilities and just... Relax.

His thoughts however where interrupted by a shout from Cisco and Caitlin, the Reverse Flash suddenly appearing next to him and doing something to the device on his arm (Cisco really needed to work on his anti-tampering by Metahumans ideas). Then to top it all off, he got struck by lightning. Again. Through a hole in the roof that wasn't supposed to be there.
How lucky could he get?

He woke up to rain pouring down on his face. He could feel mud caking his legs and soft fabric beneath him. A slight swaying motion reminded him of being at sea (his uncle had taken him on a cruise once, and let's just say that he did not have sea legs), but the low murmur of voices around him told him that he most certainly was not at sea. But why would Caitlin and Cisco call more people in? He couldn't pick out Joe's worried voice or Caitlin's calm voice from amongst the sounds, but... There was definitely something familiar about one of this voices.

A loud shout suddenly broke through the murk, along with a sudden jerk of the stretcher (he assumed that was what it was) that made his stomach twist. That was when he knew something was wrong; as the Flash, he didn't get or feel sick because of his super immune system, but here he was about to-

He sat up and projectile vomited all over the unfortunate person standing next to him. There were squeals and the sound of mud squelching as everyone backed away. Luckily no one dropped him like the last time he'd been on a stretcher. That had not been pretty (broken leg, slippy mud, cow pat, Tony landing on him... Yeah you can imagine how that went, Barry thought sarcastically).

He groaned and flopped back onto the stretcher. He cracked open an eye, before both eyes flew open in surprise. There standing covered in... Whatever the hell that was (assuming it was his sick, which was yellow. YELLOW. And that was never good either) was neither Cisco or Caitlin, or (thank God) Dr Wells. Instead it was-

"Satana?!" Oh shit. From the death glare she was giving him, he knew that- Wait.

Satana?

In Central?!

Looking round he saw the familiar grounds of Dalton Academy surrounded by heavy gray clouds and sheeting rain. He had a very sneaky suspicion that-

"Sebastian mate? You alright?" Yep, aaaand that was the confirmation he really did not want. He huffed.

"Absolutely fucking great." Just another day in his messed up life as the Fastest Man Alive where he swapped bodies with his younger arrogant, pompous self.

Must be Friday.

"Arrrrrgghh!" Caitlin and Cisco ran into the medical room, armed with a clipboard and thing-which-Cisco-hadn't-named-yet. They came in to the sight of Barry sitting up and clearly panicking. They glanced at each other curiously.

"Amnesia?," commented Cisco curiously to Caitlin.

"Possible, but highly unlikely. However with combined power of the lightning and whatever the Reverse Flash did to the device-"

"Which I still have no idea what he did. It looked all normal!"

"- it could possibly have induced some sort-"

"Can someone please tell me what the FUCK IS GOING ON." Caitlin and Cisco turned back to Barry, who still had a terrified but confused look on his face. He got out of bed, and Caitlin rushed over to push him back down.

"No! Barry, you need to stay down, we still don't know what the Reverse Flash did-"

"Fuck this!," he cried, pushing Caitlin away and stormed past Cisco. "I am in a place I don't know, I don't know who the fuck you guys are, although you my friend-" He pointed at Cisco "- really need to gain a sense of fashion. Where did you get that from, Nerds r us? Also, did you just call me Barry?" He snorted. "Heh, as if he could get me in anymore of a mess. Anyway, someone really needs to explain to me WHAT THE FU..." He tailed off. Caitlin and Cisco looked at each other. During Barry's rant, he'd rounded the corner where they couldn't see him. They shrugged, daring each other to go and look first (when he got like this, it was always best to stay out of the path of hurricane Barry). They had a game of shoulder wars, before Cisco surrendered after a particularly hard push from Caitlin which sent him stumbling out into the main Cortex to find-

Barry Allen staring at his (their) Flash uniform, his mouth hanging open in surprise.

"Oh. Shit."

Caitlin leaned over to Cisco as Barry turned around slowly to take in the entire room, a wide eyed look on his face.

"I think I win the bet," she whispered, staring at Barry's curious actions. Cisco leaned over.

"I'm going to have to agree with you. This is definitely an 11. Dr Wells on the other hand..."

"Shut up Cisco. Anyway he went home after we made sure that Barry was alright. Several hours ago!"

"Yeah, but do you still want me to phone him up and tell him that he owes you coffee for-" Their bickering was interrupted by Barry clearing his throat. He stood there with his arms folded and a high level of sass alert pretty much floating above his head.
Or that could just be the alert for when tachyon particles were detected. Or for when the toilet was blocked. Therefore they (mostly) chose to ignore it as more often than not it was the latter.

"So... Can anyone tell me what the hell just happened here?" Caitlin was about to reply when Cisco jumped in.

"Absolutely no idea, Barry. Sorry." Barry face palmed.

"Absolutely fan-fucking-tastic. I'm going to drown my sorrows while you two weirdos sort this shit out. Let me know when you can get me back to my own time." He walked out the cortex.
Caitlin and Cisco stared at each other in surprise (they seemed to be doing that a lot in the last 5 minutes), then ran after Barry.

"But you can't get drunk!," yelled Caitlin, running after Barry. Cisco wasn't far behind. They all disappeared into the cortex.

"What do you mean, back to your own time?" There was the sound scuffling and the thump of a body hitting the floor. "And if you didn't want us to catch you, why the hell didn't you flash out of here?!"

"BECAUSE LIFE."

A beats silence.

"Fair enough. Now explain to me want you meant by that last statement."

Another beat of silence.

"Why should I?"

"Because out of everyone in Central City, who do you thinks gonna believe you, Flash?"

A minute silence (yes there are a lot of silences. Get over it, Sebastian's thinking of all the possible ways to get out of this mess, until he realises that there are none so instead decides to plot against his future self and completely ruin his life for putting him in this situation, then realised he probably should trust these crazy people as they seem to know that 'he' is the Flash, then he realised he should probably answer them, then he realised that yeah... No one else was gonna believe him).

"Alright. I'll tell you." They appeared back in the cortex.

"One quick question?," asked Cisco. Barry raised an eyebrow.

"Are you secretly the Doctor?" Barry (Sebastian) had no answer to that. For all the shit that was going on right now, he might as well be.

A/N: Thanks for reading! Please review etc. I'll try and update asap in accordance with life.
