Hello guys and welcome to my first Flash/Glee crossover. Ive had this idea floating around for a while to do a 'Sebastian is Barry Allen story' so here it is. Hope you like it and dont forget to leave a review :)

Fox owns Glee and CW and DC comics owns the Flash. I do not own these or anything else you recognize ~Dmhello

Barry was in a relationship

He had to be, Iris was certain of it. For the last month he was happier and laughing more than ever. He was just different. Plus he kept smiling like an idiot when he thought no one was watching.

Yes she was sure of it.

Question is… who?

-One month prior-

Barry was 15 minutes late to work as usual. He rushed in the door and greeted the people he usually did. It seemed like a normal enough morning. Well, if you call saving people and being the fastest man alive before 9 am normal.

Yep

He was the Flash.

Barry was jogging up the stairs to his lab when he noticed a few unfamiliar faces in the crowd of his co-workers. One of them looked familiar. He looked like... Nah it couldn't be.

Barry shook it off and went to his lab.

This wasn't the first time Barry had a secret alter-ego. He used an alter-ego in high school, Sebastian Smythe. He wasn't proud of what he did, nor how he spent his time going to Dalton Academy for boys.

He was so excited to start over. To do the things that were always at the back of his mind, but never had the confidence to do. He went overboard. He acted crude, cocky, dirty, prideful, and downright evil.

It wasn't all bad though. Sebastian gave him more confidence. He sang, danced, learned how to defend himself with his words, and acted as 'out' as he wanted without anyone caring. Barry shook his head to get him out of his thoughts once again. That part of him was gone. Now he was graduated and back to the real world, and he had work to do. God knows how long it would be before another crime was committed and he had to dash away.

"Hey Barry" he looked up from his computer to see Eddie, Isis' boyfriend and his foster Dad's partner.

"Hey Eddie."

"Singh wants to see us in his office."

"Us? Oh Eddie, what did you do?"

"Very funny Allen" he rolled his eyes and smiled at the brunette. They headed downstairs to their captain-David Singhs-office.

Barry walked in and looked around. Some military people stood around Singh's desk. He felt his heart beat go up and sweat start to beat on his brow. He remembered the last time the military tried to take over one of their cases. It didn't end well. He looked at all the new faces in the room, two guys and a girl.

Oh

Oh no

He took a good look at the sand-haired man at the far right of the room. The blood drained from his face and his stomach filled with dread. Staring back at him were the blue eyes of Hunter Clarington. He wanted to leave, just super-speed away and crawl in a very Barry Allen shaped hole. Anything but seeing him.

"Allen, Thawne, these are your new co-workers"

"What?" Barry chocked.

"These are army soldiers who are sent to help us with the...delicate cases we've been facing lately."

"The meta-humans you mean?" Barry asked looking around at anything but his ex.

"With all the respect Sir, I think we can handle them. We have the Flash." Eddie pointed out, Barry smiled but stayed silent. He didn't want Hunter to notice him seeing he was still facing the captain.

"It's a little too late to argue this Thawne. Anyways, you will be working with these two." He pointed to the women and the man to Hunter's left. "And Allen, you will be working with Clarington in the lab."

This was it, Barry's worst nightmare. Just kill him now it would be less painful that sharing his work space with his ex- warbler co-captain. He'd take anyone at this point. Jeff, Nick, Trent; heck Blaine would be better than this.

He made eye contact with Hunter. The surprised look on his face almost made him laugh...almost. He hadn't changed much since high school. He just had shorter hair, he was taller, and now more muscular (He didn't even think that was possible.)

"You're dismissed." Singh waved them off, going back to his papers.

Barry and Eddie left the room first. Barry was nervous and a little scarred to be working with Hunter. He must have shown it.

"Barry, you okay? You look like you've seen a ghost."

Barry swallowed. What was Barry going to do? The last thing he'd want happening is Eddie or anyone else finding out about Sebastian. They would never look at him the same.

"I'm okay Eddie. It's just- I know the guy I'm working with, from high school"

"Really, Iris didn't recognize any of them when she came in?"

"We went to a different high school. Bullying got really bad so I transferred my sophmore year."

"Oh, okay" Eddie nodded understandably "Where'd you go?"

"Dalton Academy."

"I didn't know you were a prep boy." Barry sent a glare at Eddie. He was not going to be called a prep, even if it was true at one point.

Hunter and the other soldiers came out of the captain's office. Barry braced himself for a wave of awkward.

"Well, see you around Barry." Eddie left with his two new workers. That just left Hunter and him alone trying to not look each other in the eye for too long. Oh god.

"Hi" was all Barry could squeak out.

"Hello"

"You joined the Army."

"Um… yes?"

"And your taller than me now" Barry stepped closer to Hunter and measured his height with his hand and glided it above his head. "And youre more muscular, seriously Hunt thats just not fair."

Something must of clicked it Hunters mind when Barry gave him his signature smirk.

"I'm sorry, do I know you?"

"Hunt, I'm offended. Out of all the people in our little Warbler nest the last person I'd expect you to forget is ." Hunters eye became the size of saucers. "I'll explain everything in the lab, come on, its this way." Out of habit he grabbed Hunters sleeve and pulled him upstairs to his lab. Once he closed the door he turned around and found himself pressed up against it.

"Okay Sebastian, or Barry, or whatever your name is now, start talking!" Hunter looked angry and confused. Barry tried to keep his cool and explain it clearly.

"Okay, okay I'll explain it just let go youre starting to hurt me." Hunter loosed him grip on the green-eyed boy "Thank you."

"Well?" Hunter demanded.

"Um… well, Dalton was my chance to start over. So thats what I did, name and all. I did things that I wanted, acted as crazy as I wanted to, and flirted with whomever without getting bullied for it. As you know, I took it too far and went overboard."

"We both kind of did."

"Yeah no kidding! Anyways, I'm back in the real world now. And I'm never acting like that again. So Sebastian disappeared and no one around here found out about him, and I'd like to keep it that way."

"Wow" he backed off and sat down on one of the wheelie chairs. "You really turned it around huh?"

"Yeah, no one here even knows I'm bi."

"Whoa, whoa, wait… since when are you into the V?"

"It was an all-boys school Hunt, name one V that I could have access too. Plus I kind of had a crush back home so…yeah." Barry stood there awkwardly, not wanting to talk about my former love for Iris.

"Point taken, so how do thing work around here hmm? Now that I'm working with you."

"A lot of boring science-y stuff." Barry turned around to see Iris. Speak of the devil.

"Iris please, youll scare him off." Barry said teasingly. Hunter just glared at him. "Hunter this is my best friend Iris West, Iris this is Hunter Clarington."

"Hi" Hunter shook her hand.

"Well, I'll leave you two to work. Nice meeting you Hunter."

"Likewise Miss Iris" Hunter said as she closed the door.

"Look at you being all polite and stuff" Barry teased.

"I'm military, I have to be polite now, especially to civilians." He stated

"You weren't polite to me" Barry fake pouted.

"Yeah well, you're you. I only have to tolerate you."

"But I'm not the person you know. I'm Barry Allen. You barely know this side of me."

"Barry Allen or Sebastian Smythe, either way you're still annoying. How different can they be?" Barry almost doubled over laughing.

"You'd be surprised" Barry inched closer to his former roommate and fixed his tie. "Now let's get you situated, shall we?" He walked off to get Joe to get Hunter his stuff.

"Tease" Hunter stated before following him downstairs.

Thee three of them got Hunter a working space ready in the lab.

"Well" Joe said. "This should be enough to get a good start. Hopefully you can tolerate sharing your space with him." He whispered to Hunter jokingly.

Hunter chuckled. "If I can handle being his roommate I think I can handle him in here."

"Right, Eddie told me you guys were classmates. How was that?"

"Not completely terrible."

"Hey, I can hear you!"

"Suppose too!" Barry grit his teeth and Hunter showed his. He loved hitting all of Barry's buttons. He was-after all that time spending together-very good at it. Joe saw all the heavy lifting was done and left them alone.

"Well, you're all set up, and I'm done for the day. Want to catch up? I still have about a million questions for you Clarington." Barry stated.

"Sure, you can show me around if you want. Still don't know a lot about this city. I've only been here once before."

"Really when?" Barry questioned

"Last year, they needed guards at STAR labs because of all the protests. That ended well."

"You were here the night of the explosion?" Barry was dumbfounded. If Hunter was there did he get hit? Was there a chance he was a meta-human too?

"Yeah kind of sucked. Were you there?"

"I was there when they turned it on, but then I went back here. Got struck by lightning that night though."

"You what?!" Hunter exclaimed worry pooling in his crystal eyes. "But you're okay now tough, right?"

"Yeah, I mean I was in a coma for a little while but, other than that I'm more than okay." Hunter took a relived breath. "So coffee?" Barry said trying to change the subject.

"Sounds good."
