Sebastian really wishes Blaine would leave. It was hard enough seeing him again, but did he have to worm his way into this conversation?
"Anderson, we need to talk. Barry, stay here." Sebastian drags Blaine out into the hall, checking first to make sure Barry couldn't hear them before speaking.
"Killer, you need to leave." He begins.
"Why doesn't your own brother know? Are you ashamed?" Blaine asks. "And this is why you lied about where you got those injuries?"
"I'm not ashamed." Sebastian says. "I just..." He trails off and lets out a deep breath.
"You're scared." Blaine realizes. Sebastian's head snaps up.
"I'm not scared. Why would I be scared?" He scoffs.
"No, you're scared. You're worried what he's going to think of you." Blaine says.
"You're high, Anderson," is Sebastian's only reply.
"It's okay to be scared. He's your brother. It's natural to be worried what he thinks of you. But you shouldn't be. He'll still love you." Blaine tries to comfort Sebastian, but Sebastian pushes him away.
"I don't care what he thinks. I don't need him to like me. He doesn't anyways. We can't stand each other."
"Maybe he doesn't like you, but he loves you. And you love him." Blaine says. "Just tell him. And you know what? If he hates you for it, you have other people here in Central. Friends." Sebastian looks away.
"What if I don't want to tell him?"
"Why not? Why bother living a lie?" Blaine points out. "Look, it's your decision. You're 24. But, if you want to do it now, I will be here next to you the entire time."
Sebastian sighs. "I can see why Hummel married you." Blaine winces, but Sebastian's too caught up in his dilemma to notice.
"I can't do this." Sebastian sighs. "Look, I moved here to get away from all this."
Blaine raises his eyebrows. "To get away from your father? Or yourself?" Sebastian doesn't answer and Blaine doesn't push him further.
"Hey, I get things are kinda weird between us, but if you ever want to talk or anything, give me a call." Blaine hands Sebastian a business card.
"Is that even allowed? I thought Hummel had you under lock and key? Or has he actually lightened up since you tied the knot?" Sebastian quips, but Blaine doesn't laugh.
"We're not married. He broke off the engagement right before the wedding. Look, I gotta go, but maybe I'll see you around." Blaine leaves quickly, scared to see Sebastian's reaction to the fact that he's single. Blaine doesn't know how he wants Sebastian to feel about it, so he rushes away.
Sebastian is rooted to where he's standing. The only thing that brings him back to reality is Barry walking out of the lab.
"What's taking you guys so long?"

Barry finally gets tired of waiting and walks out of the lab to find Blaine and Sebastian. When he steps out the door though, he only sees Sebastian, who looks shocked.
"What's going on? Where's Blaine?" Barry asks and Sebastian blinks.
"What?"
"Are you going to explain what's going on?" Barry asks.
"No." Sebastian says abruptly and immediately goes down the stairs to leave the precinct, ignoring the fact that every pair of eyes is watching him leave. Barry stands at the top of the stairs in utter confusion. As the door of the precinct slams shut, the eyes slowly move up to Barry and he flushes before fleeing back to his lab.
Down on the ground floor, Joe lets out a heavy sigh and walks up to the lab.
"I take it he didn't explain?" He asks Barry, who's sitting slumped in his chair.
"No. He and Blaine had a heated conversation in the hallway and then they both left." Barry responds.
"Blaine?" Joe asks, not recognizing the name.
"The guy who almost got murdered? The one who made that weird comment about Seb liking women? Apparently he and Seb met in high school?" Barry explains.
"Huh. Did you find out what his comment meant?" Joe asks.
"No. It seemed like Seb didn't want him to say anything." Barry says. They're both quiet for a minute.
"Barry?" Joe asks.
"Yeah?"
"Do you think Sebastian's gay?" Joe continues hesitantly. Barry doesn't respond. "It's just, that's the only context I can come up with in which Blaine's comment makes sense."
"Why would he hide it though? And then why would he sleep with a woman?" Barry asks.
"Maybe he didn't. Maybe he just doesn't want us to know how he got injured." Joe suggests. "Look, I gotta get back to work. See you at home?"
"Yeah." Barry replies, still deep in thought. He was going to figure out what was going on with Sebastian.
