Nothing Is That Simple

The Flash, Glee, Arrow, Legends of Tomorrow Crossover

Barry Allen was Sebastian Smythe; he thought he could keep that part of his life separate from his life now but nothing is ever that simple for him.

Timeline: The Flash (Post season 1 but the team is back together, but no breaches to Earth 2 or Zoom), Arrow (post Season 5 so it's just Oliver and Felicity are around), Legends of Tomorrow (post season 1 but Len lives)

Disclaimer: I do not own The Flash, Glee or Arrow.

Also I have never seen Glee other than watching YouTube videos of Grant's performances in the show and damn this needed to be written.

Chapter Two

"I know I'm engaged and all, but hot damn. No offence babe." Nick let out a low whistle when they came into sight of Sebastian who was standing between Oliver Queen and the 'sexy as fuck older guy in a parka'.

"None taken, what I wouldn't give to be part of that threesome." Jeff leered at the three across the park.

"Focus guys." Blaine scolded, but he hadn't taken his eyes off the trio.

"I'll get him, Oliver knows me now besides I want to see what happens when I remind Sebastian of our time in Pairs, Blainey you might want to cover your eyes." Cooper winked at his brother who wrinkled his nose up.

"Don't forgot to bring him back to us." Thad called after Cooper who was sauntering over to the group across the way.

"Barry!" Cooper called out as he came up behind Sebastian, wrapping his arms tightly around the smaller man.

"Ah? Coop-mhpf." The brunet's head was turned to the side and Cooper sealed his lips over the brunet's to cut off Sebastian's words. Cooper felt Sebastian melt in his embrace and twist completely in his embrace to cling to his body, their firm bodies pressing against each other in a familiar way. Cooper pulled back, smirking at the flush on Sebastian's face and glazed over look in his eyes.

"Scarlet, who the hell is this?" The unknown guy in the parka growled, actually growled out as Cooper kept one arm slung around the smaller man's waist.

"Cooper Anderson." Cooper stuck his free hand out to the unknown man, smirk still on his face.

"Leonard Snart." The man's grip was strong and tight and Cooper was damn sure he was trying to break his hand.

"What the hell? Why are you here Cooper?" Sebastian hissed once he realized what was actually happening, he elbowed the actor while giving Leonard a warning look as his fingers twitched like he was resisting the urge to reach for something.

"Since I saw you last night I knew I had to stick around. We have to catch up." Cooper rested his cheek on Sebastian's head, pleased that even though his hair was spiked up it was still soft, even more pleased as the glares he was getting from Snart and Queen intensified.

"You couldn't just call me like a normal person?" Sebastian raised an eyebrow unimpressed as he allowed Cooper to stay where he was.

"It's like you don't know me at all. Ah I remember the good ole days in Pairs where you were this adorable, stuttering mess. Oh how far we've come!" Cooper said dramatically.

"You were always a ham Cooper, a sexy ham but always a ham. No wonder you're an actor." Sebastian rolled his eyes, leaning against Cooper and he took that as a win.

"Barry?" Oliver interrupted, having got over the shock of seeing Barry making out with the movie star they had met last night.

"Right, you want answers huh?" Sebastian winced knowing that look on Oliver's face.

"No time for that, sorry boys but my friends and I have been waiting to get answers out of 'Barry' since he disappeared from New York." Cooper steered Sebastian away from the two.

"Hold on a second!" Sebastian protested before he caught sight of Blaine, Kurt, Thad, Nick and Jeff waving at him from across the park and he slumped in Cooper's arm and gave in to seeing them all again.

"I'll explain everything later." Sebastian called over his shoulder to the two older men as Cooper ushered him across the park to his high school friends.

"Bas!" Thad rushed forward to embrace his ex-roommate in a tight hug, spinning the smaller man around. Sebastian hugged back, mostly to hang on for his life.

"Put me down asshole I'm not your doll." Sebastian snarked, Thad laughed at his friend and placed him back on his feet.

"Sebby!"

"Seb!" Nick and Jeff sang as they sandwiched him in a hug.

"Are those phones in your pockets or are you two very happy to see me?" Sebastian wiggled his eyebrows.

"Both." Nick teased back placing a loud smacking kiss on Sebastian's cheek meanwhile Jeff nuzzled Sebastian's hair.

"Stop hogging the Meerkat." Kurt chided, reaching in to pull Sebastian out of the sandwich to hug his enemy turned friend in a tight hug, still shaken up about the fact he had been hit by lightning and stuck in a coma for 9 months.

"Lady Hummel I see your gay face hasn't changed since we last spoke." Sebastian smirked and Kurt took the insults with a roll of his eyes, knowing this was a way Sebastian showed his like for people (well at least now it was, in high school not so much).

"I don't know if I should be jealous or turned on." Blaine teased.

"Well jealous sex is always pretty hot from my experience." Sebastian winked as he and Kurt pulled back from their hug.

"Get over here Killer, I know you missed me." Sebastian held his arms open, Blaine laughed before he flung himself into the offered hug.

"God Bastian, don't ever do that again." Blaine breathed out.

"No worries Blaine, no more coma's." Sebastian promised loud enough for the others to hear as well.

"Come on we have to catch up!" Nick grabbed Sebastian's hand dragging him out of Blaine's grip.

"Where do you want to go?" Sebastian asked as he allowed Nick and Jeff to link arms with him as the group started to move onwards.

"I'm sure you know the best coffee shop around here, so let's head there." Blaine suggested remembering Sebastian's addiction to coffee.

"To Jitters it is then." Sebastian nodded his head sagely and adjusted the group's direction.

"So Oliver Queen?" Kurt prodded as the group claimed the upper level of Jitters for them selves, cups of coffee and plates of pastries sitting on the tabletops in front of them.

"What about him?" Sebastian asked as he slurped his 'Flash' drink, thinking back to what Len said about getting him an 'Iced Flash', his favorite drink, of course it made him blush well scarlet and Oliver had not been pleased.

"How do you even know him?" Kurt asked, more interested in knowing Sebastian's connection to the infamous Oliver Queen.

"A year or so ago, I was down in Star City for a case and we kind of ran into each other and became friends." Sebastian shrugged his shoulders editing down the actual story of how he met Oliver.

"Friends, huh? I don't believe that for a second." Kurt grumbled as he sipped his tea.

"Speaking of, a COMA Bas!" Thad exclaimed, worry seeping into his words.

"Ah, you heard about that huh?" Sebastian winced and sunk down in his chair as they all glared at him.

"Heard about it! Not until a day or so ago!" Blaine exploded before Kurt hugged his shoulders and Blaine took a few calming breath's.

"I feel like this is part of a longer story, Barry Allen." Cooper spoke up, crossing his arms as he gave Sebastian a stern look.

"About that…" Sebastian rubbed his neck looking away shyly.

"Some backstory would be nice Sebby." Nick said softly, bringing Sebastian's attention him, he didn't look too angry or full of judgment and Sebastian relaxed knowing Nick wasn't the type to get angry.

"Okay, here goes nothing." Sebastian ran his hand through his hair, spiking it up further.

"I was born Bartholomew Sebastian Henry Allen." Sebastian began as he leaned forward on his elbows, lacing his fingers together his voice low so they all had to lean closer to hear him.

"That's a mouthful." Jeff snickered before his fiancée elbowed him.

"Why do you think I go by Barry?" Sebastian laughed slightly.

"Or Sebastian." Blaine added and Sebastian winced back at the tone of his voice.

"Or Sebastian." Sebastian agreed.

"Why did you change your name and apparently everything about yourself?" Cooper asked curiously, he was lining up the first time he met Sebastian with the Barry Allen he saw in front of him now and understood why he was a stuttering mess when they first met.

"When I was 11 I saw my mother murdered in front of me by something impossible and my father was wrongfully imprisoned for her murder." Sebastian said softly.

"Your mom?" Thad asked confused as he clearly remembered meeting his mother and father back at Dalton.

"Oh Bastian I'm so sorry." Blaine reached across the table to grip Sebastian's hand in comfort.

"No one believed me, not even my foster father and sister. I finally got the man who killed her, but my father is still in jail." Sebastian clenched his free hand in anger as he thought about Eobard Thawne/Harrison Wells. Blaine's frown deepened as he felt Sebastian's hand tremble in his grasp, so Blaine just held on tighter.

"Bastard got what was coming to him then." Kurt said darkly as he allowed Blaine to hold Sebastian's hand in comfort.

"Anyways I was a skinny, nerd whose father killed his mother and talked about impossible things like men in yellow lighting with red eyes, well it made me prime target. It was also the time period that I was realizing I was attracted to both guys and girls… I'm sure you can imagine what happened when bullies got ahold of me." Sebastian forged on refusing to let his mind linger on what Thawne did to his family and friends.

"No Bastian…" Blaine covered his mouth with his free hand and Kurt let out a low growl, as they both had been targets of bullying before.

"After I was hospitalized…" Sebastian starred but was interrupted by sounds of outrage and questions of who they had to hurt. Sebastian smiled, getting a warm feeling in his chest at how protective they all were of him, even after everything back in Dalton.

"Keep going." Kurt said through clenched teeth.

"My uncle from my mother's side Drew Smythe came to visit me and offered me a chance to come live with him in Paris and to meet my new aunt Michelle Smythe. I had to get away so I took him up on the offer and I moved to Paris and became Sebastian Smythe, deciding I wasn't going to let anyone walk over me again and that kind of turned me into an asshole and a bully… You guys know the rest. I would also like you guys to not telling anyone else about this, I mean no one here knows about the real Sebastian Smythe and I kind of want to keep it that way. " Sebastian explained and gave Blaine and Kurt a look full of regret.

"…Things make sense again!" Thad threw his hands up in the air as the others made their own sounds of agreement and understanding while promising to keep this to them selves.

"We are still calling you Sebastian." Nick said firmly.

"I would never want you guys to call me anything else, I'm fond of my nicknames." Sebastian laughed.

"Even Twink and the Criminal Chipmunk?" Kurt teased.

"Considering I kind of look like a Twink I take no offence." Sebastian laughed the nicknames off.

"Speaking of… Tell us about Oliver Queen and the silver fox in the parka. Details Seb!" Jeff leaned forward and Sebastian let out a groan as he dropped his head onto the table to hide his blushing face.

"His name is Leonard Snart and is very protective of our Bassy here." Cooper chimed in, still processing what Sebastian had told them.

"Details now." Nick demanded and Sebastian groaned out like he was in pain causing his friends to burst out into laughter.

"Why are we all still friends?" Sebastian muttered to himself.
