Inspired by Alter Alyce's stories. Character study of Sebastian Smythe, I just started to watch Flash and fall in love with Barry Allen. Imagine my surprise that Grant Gustin played at Glee as an antagonist character, whose character differ with Barry's character like the Sky and the Earth. And so, although I am starting to watch Glee, I want to write a little about Sebastian. May be a bit OOC, and crossover AU with the Flash (2014), with Barry as his twin brother.

Disclaimer : I don't own The Flash or Glee.

Sebastian lay on his bed at his dorm room. The feeling of tiredness and guilt washed over his body. He had just finished from Lacrosse practice, and it might be caused from the Warblers' attitude towards him. Last week he had 'slushied' Blaine, his current crush. Although the slushie was intended for Kurt, particularly for his clothes, but Blaine had taken the red colored glob with his face, resulted in him to be taken to the nearest hospital, because some of it entered his right eye and had to be operated. He himself had several experiences to clean the drink stain, because his twin brother's bullies had done the same several times before, much to his chagrin, and let him tell you, cleaning them were not easy at all. Thus, adding some rock salt to delay the defrosting of ice, and knowing Kurt's passion for fashion, he thought this was a perfect prank.

Well, he did intent to help him cleaning his shirt later, if he asked, but he did not predict Blaine's action and that the red abomination with salt to hurt the said gelled hair boy's eye. He was annoyed with Kurt, yes, but not enough to hurt him, or his boyfriend for the matter, and now the respect held from the Warblers just perished into the thin air. He knew that he deserved them, the hateful looks that they sent to him, some pranks they did and sometimes they just ignored his order when the Warbler practices being held, but all of them was stressful and tiring.

He had just dug his grave deeper by blackmailing the one and only Rachel Berry, the said girl was very annoying, with her overconfidence and selfishness (not that he himself did not have the same problems), and that Finn Hudson was Kurt's step brother was just an added bonus. Well, he did dislike the said boy fashion sense, and that he wanted to test their relationship, his crush and jealousy were just some minor factors, major, whatever.

Later, oh so his brother (not) helpful advice, his behaviors were very unbecoming and rude and plain nasty. And that he demanded him to apologize. Sebastian Harold Smythe Allen did not apologize, at all. And here he thought his brother understand that. He had never apologized to Barry for what his wrong doings, what made him think that he would do that for some nameless faces from public high school? Unthinkable.

"Bas, let me clarify again." Barry voice came clear from his phone. "You don't want to apologize because you never said it to me?"

"What? No! I said I don't have to apologize for some measly things like these!"

"You made a boy your age go to the hospital, Bas, and then you blackmailed the main lead with a photos-hoped photos of her... uh," he could hear Barry blushed from here, "naked boyfriend, and you don't want to apologize?"

Sebastian pouted, if he made it sound like that, they did sound ridiculous. "Bas, I know that Uncle Alex has some connections so that this will not show on your record, but think about your future if they press charges. Don't you feel guilty about hurting them? I know you didn't mean it, but that doesn't mean the others know that. And yes, these incidents are your fault, Bas, they were childish and underhanded, but everyone make mistakes, and if you do apologize, they may forgive you."

He really wished that he had talked the advice back then, but no, he went moping to Scandal, because his little brother did not back him up, and although he was correct, Sebastian did not want to accept that truth yet.

"So... How do you get a guy to like you?"

He looked at the source of the voice while smirking, mask back in place, he would not let anyone see him moping, or let anyone trampled over him for small matters like these, except for Barry, of course. The only one in the world that he could trust, although he kind of mad at him right now.

"You get the guy," he easily replied, this guy was annoying. Couldn't he see that he wanted to be left alone? Never hit on him when he wanted to be alone. Especially if you are just out of the closed guys. He mocked him, "please."

"Why? What's wrong with me?" he looked shocked, really?

"Huh, first of all, you are about a hundred pounds overweight. Quit waxing your eyebrows, you looked like a Liboracci. In fact," he faced the guy, "just stay in the closet, Buddy," before turning away to get more drinks.

A few days later, came the gossip that Dave Karofsky tried to commit suicide. His face turned white, he even excused himself from his French class, despite the teacher yelling and all his classmates' eyes on him. Never had he thought he could be the one to send people over the edge, not after everything happened to his brother. He quickly went to the bathroom, washed his face, saying "Oh my God," again and again.

He remembered seeing his baby brother laying on the hospital bed, looking so pale and fragile. They had always been pale, and Barry had always been lanky and delicate looking, but it had never like that. He had tried to cut his wrist, and was found by Detective West. Thank God above for that, if not, he might have lost his brother forever. He walked to him, caressing his paler than usual face.

Barry opened his eyes, looking tired, but that never beat that he was alive. "Hey."

"Hey," he replied. "I fly here as soon as possible after hearing this, you're on 72 hours suicide watch," he gulped, "Why Bear?"

Barry never looked so dejected like that, even when people did not believe him. He always wears his emotion on his sleeve, and that made him every bully's wet dream. He vowed he would not make that kind of face ever again. "I…" tears formed on his eyes, "I was so tired, Bas, and thought that nobody would notice if I am gone, sorry, I didn't think of you."

"Oh, Bear…" he hugged the boy, and they cried together, which he would deny if anybody asked. And stayed there for a week, before his junior high school principle demanded him to be back to Paris. They split up after the murder. Bas was not home that night, having a sleepover at a friend house. And Barry's words were… impossible, although the fact that Barry could not lie to save his life for that matter helped a lot. He did believe that his father would not done that, plus, he did not have the motive. But, still, nobody in the world believed the two boys. In the end, Barry went with Joe, but the said man could not afford 3 children with a police officer salary. He asked Uncle Alex to adopt him, leaving Barry alone while he at the other side of the world, Paris. Which was the greatest mistake he had ever made.

And he made a second one. Composing himself, he went straight to his room and called his brother. "Bear."

"Bas, hey, what's wrong?" Concern rolled from his tone. Sebastian never called when the class still in session, so this had to be important. And he told him everything, once he opened his mouth, all of them just rolled over his tongue. Near tears, desperate, he asked his brother. "What should I do?"

Later, after they hang up, and this time, Sebastian made sure he would follow his brother advice, he called Santana, Kurt and Blaine to meet up at the Lima Bean. His eyes widen at surprise to see Thad, Nick, Jeff and Trent were in front of his door, with their neck strained like they were eavesdropping, and they were doing just that. He looked at them, unamused, eyebrows shot up asking the silent question 'what are you guys doing here?'

"Hey… Bas?" Thad said. They never called him Bas, that was Barry's privilege.

"Uh-huh."

"Uh… we are concerned because you just fled like that from class," Trent reasoned. Nick grinned, "and curious of why."

"We didn't mean to… uh, eavesdrop, but it seemed this… Bear? Has everything covered," Jeff continued. "And it was not just four of us, anyway," he mumbled. Sebastian headed to his next door floor mate's room, and found the rest of the Warblers there. He did not know that the walls were that thin. He sighed, "Right… And I have a business to attend to," he could hear the relieved sighs, he smirked at that and continued with face cheerful tone, "but we will talk about this when I got back." Groans could be heard and terrified looks could be seen.

He had his book and notes open, trying to smooth his nervousness before the guests came. But whatever he did, the feeling did not go away. In the end, he saw 4 teens walked in the cafe. Santana was the first one to notice him and pulled out the chair across him.

"Let me break it down to you," she said venomously as the other cheerleader, Kurt and Blaine stood nearby, glaring. "From one bitch to another. All this vicious underhanded crap has got to stop."

"Exactly," he agreed, guilt flashed from his face again. "That's why I called you here. First of all, Blaine," he looked straight at his former friend and crush in the eyes. "I am sorry about your eye."

"That means nothing to me," he said venomously.

"Just give me a chance," he pleaded, and took a deep breath. "I have no excuses other than some lame prank gone completely out of control. Secondly, the Finn photos have all been destroyed. I want the Warblers to win fair and square. And we are going to take donations for Lady Gaga's Born this way Foundation." He then looked at Blaine and Kurt, "win, lose or draw, we are going to dedicate our performance to Dave Karofsky. I thought you might want to join us."

"Wait for the punch," Kurt whispered to Blaine, hateful looks still directed to him, "you know it's coming."

"No, not this time," he responded, "for too long, I have treated everything... like a big joke." He couldn't help think of Dave Karofsky lying on the white covered bed, and compared that with Barry. Then think back of what he had said to him. He never wanted to harm anyone. It was just words. He should have known that sometimes, words could be sharper than anything.

"It's all fun and games," he said, "until it's not."

When he arrived at the Warblers practice room straight from the Lima Beans, he found all of them inside, and the conversation soon muted after they saw him.

"Right," Sebastian started, cutting the awkward silence. "I apologize to you guys for being a jerk this whole semester, and that I caused so many dramas around our school and McKinley, and strained your friendship with them."

They all looked at him like he sprouted 10 heads and said he liked girls. "I have said to the school board that the slushie incident was all my fault, forced you guys to come with me, and I would take all the responsibility for it. To compensate with you guys, after Regionals, whether we win or lose, I will withdraw from the Warblers."

With the bomb dropped, the chaos ensued. "What do you mean you will withdraw, Seb?" Thad asked. "We are at fault too. I mean, we disbanded the Warbler council 'cause we don't want the responsibility for that. And we are your friends, we should have said to you that you are wrong. And stayed by your side no matter what. But you have to resort to your Bear friend in Paris. We are wrong too."

Sebastian nearly chuckled at that 'Bear friend in Paris' comment, but managed to keep his face straight. "He is not-"

"Bas."

Okay, there we go. Don't forget to review on your way out!
