Sebastian has never apologized before, ever. Even when he screwed up big time to his only brother. But when the said brother told him to apologize for his mistakes, he selfishly ignores them and goes to the Scandal, where he makes the second biggest mistake in his life. This time, he wants to right his wrongs.

Sebastian and Barry Allen are the twin sons of Henry and Nora Allen. After the incident, they were separated. Barry going the the Wests while Sebastian went to his godfather Alex Smythe. This is the story of what happened to the two young boys separated by a tragedy.

"It's…it's cancer, Joe," Barry whispered. Joe's face didn't change. He didn't say anything. He just stared at him. "W-what?" he finally whispered. "Please don't freak out," Barry said quickly, "Don't make a bigger deal out of it than it is. Caitlin's going to treat it, and everything's going to be fine." "You have cancer?" Joe asked numbly. (Major rewrite of Crashing)

There were a number of times where Barry Allen had to switch into the alter ego he used in high school, Sebastian Smythe. This is a collection of the numerous times he had to do so.

Before Barry Allen was the lovable person Central City thinks they know and love, he was Sebastian Smythe. Now Barry is trying to move past high school. Will one Hunter Clarington ruin it all? Things get even more complicated when he finds out: Hunter is a meta-human.

The others would all recover and move on, but the Central City Metacide would follow Barry for the rest of his life. He would never be free of it. He was the face of it. He was the walking mascot of the Lucy Resistance, the washed up hero of Central City, who wasn't even sure if he was ever going to don his suit again. Sequel to Prejudice.

"Barry doesn't want to be found," Cisco said sadly, "And he might be a bit confused emotionally now, but Barry's still smart. He knows how to disappear. I doubt we'd be able to track him even without his powers, but with them? We don't stand a chance. We have no clue where he could be." (Part 3 to The First Cut is the Deepest and Picking up the Pieces.)

Barry could hear them knocking on the walls, searching every inch of the house. It was clear to him then. He wasn't the first metahuman who had tried to hide. They were going to find him.

"Please stop saying 'illness!" Barry shouted, "Just call it what it is! It's cancer! I'm not going to break if you say the word. I'm so tired of everybody tiptoeing around me like I'm made of glass. You think I don't hear you and Iris whispering about me when I'm not in the room? I can still hear! I'm not deaf, Joe! I just have cancer!" (Original version of "Vitality")

"Iris…I'm sick." Iris felt her blood run cold. "What do you mean?" she demanded instantly, "What do you mean you're sick? Sick with what?" But she knew what already. She knew from the looks on both of their faces what it was. "The cancer is back," Barry whispered. (Sequel to Crashing)

The prospect of planning a funeral for Barry right now just seemed like too much for them all to bear at the moment. They all looked mournfully at the empty bed. Seeing it stripped bare and void of sheets was heartbreaking for them. Just yesterday, Barry had been living and breathing, lying in that bed. And now it was empty.

"Who's Sebastian?" Caitlin asked. Barry sighed. He knew he'd have to tell them eventually. Might as well be now. "He's my brother," he said with a scowl. Caitlin and Cisco's eyes both widened in shock. "You have a brother?"

"I'm here to kill our greatest enemy, Flash," Future Barry gritted. - "And who's that?" Barry asked, "Who's our greatest enemy?" - "You are."

Iris was alone washing the dishes after dinner one night when she suddenly felt a pair of arms wrap around her. She stiffened when she felt E2 Barry press his body against hers from behind. "Umm," she said awkwardly, not moving a muscle. E2 Barry was oblivious to her lack of response though. He was too busy pressing light kisses to what he thought was his wife's neck.

More into from Sebastian/Barry's life :) Outtakes from Who is Sebastian Smythe? and Who is Barry Allen?

A large scar was visible on Barry's inner forearm. It wasn't just a normal scar though. It was a brand. The numbers 0227 had been permanently burnt into his skin. Joe felt himself be consumed with white hot rage when he looked at it. They had branded his son like he was some kind of animal. (Part 2 to The First Cut is the Deepest. Can be read by itself though.)

""How the hell do you think I feel every damn day when you go out there against some meta? How do you think I feel when you leave and it might be the last time I see you?" Barry is pissed when Iris puts herself in danger. And they fight over his need for her to be safe and her need to do her job. Barry/Iris.

When Leonard Snart is emotionally exhausted, he turns to his boyfriend for comfort...and a nap. Coldflash. Barry Allen. Leonard Snart.

Barry kept his head down in shame as he walked through the station. All of the officers at the CCPD were staring at him, no doubt wondering why he was wearing handcuffs and being pushed forward by Officer Liddell towards the booking area.

Barry could feel himself breaking down, the corners of his mind starting to unravel, having already reached his limit a long time ago. Each day, he felt more pieces of himself—his identity, who he was—being chipped away with each experiment they did on him.

It's Dalton Academy's 7 year school reunion. It is in a different city every year, and this year it is in. Yes you guessed it Central City. Will Barry Allen slip back into his role of Sebastian Smythe or will he show everyone he is a changed guy.

If Sebastian Smythe was his 'Auntie Snixx', then Barry Allen has a lot of explaining to do. {I do not own the Michael Jackson song nor any of the Glee or Flash characters in this story. The plot lines that stray from CANNON are mine, however.}

Barry has unfortunate encounters with some people from his past looking for payback. Hence the slushies. Rating has gone up to T for slight language.

Sebastian and Barry were never close brothers, this only got worse after their mother's murder. So when Sebastian takes it upon himself to visit Central City nothing good could come of it. Allen twins!AU No pairings.
