Chapter One

"I don't understand why this is so upsetting." Blaine was trying for the umpteenth time to get through to Kurt. It still wasn't working.

"He nearly blinded you, Blaine! How could you forgive him so easily?" Kurt was nearly shouting, causing Blaine to flinch. It felt like they were always fighting these days, and though Kurt always claimed it was due to Sebastian, Blaine knew it was more. It was difficult to keep his thoughts organized with Kurt yelling at him though. He had planned on full disclosure with his boyfriend – an attempt to show him that he wasn't cheating, like Kurt seemed to think. It was why he brought up his intention to remain friends with Sebastian in the first place.

Obviously he should've just kept it to himself.

"You don't know him, Kurt. It was just a prank that got out of hand. I'm fine, and he apologized. Why can't you just let it go?" Ok, so that wasn't strictly true. Sebastian hasn't apologized yet, but in his defense, they haven't spoken at all since the incident.

"Because I don't want you to be friends with him!"

Since when did he decide who I could be friends with? Blaine stared at Kurt, though he didn't really see him. There was no way this controlling boy was the Kurt Hummel he fell in love with.

"Kurt, you can't choose who I'm friends with," Blaine's voice had quieted, and his eyes dropped to the hospital blanket that draped over his legs. He knew that this needed to end, knew that things were past the point of being salvageable. It didn't make it any easier.

"Maybe we should take a break. I already have a controlling father; I don't need a controlling boyfriend too." He caught his lower lip in his teeth, a habit he had picked up years ago whenever he got anxious.

"What? Blaine…" Kurt's voice suddenly had a panicked edge, and he attempted to backpedal. "I don't want to control you. I only want what's – "

"You don't get to decide what's best for me," Blaine said, quickly cutting off his excuse. He started picking at a loose thread.

"Blaine..."

"Please leave." Blaine really didn't want to hear anymore. He knew that if he listened, he would cave in and give Kurt yet another chance. It happened enough for Blaine to realize how easily he caved, and that hearing Kurt pleading for his forgiveness would only cause himself to feel guilty. This was the right thing to do; he tried to convince himself, even as Kurt stood up with as scowl on his face.

"Good to know you pick the boy who assaulted you over your boyfriend." He turned and stormed out of the room before Blaine could respond, not that he had even planned on it.

Blaine sighed and reclined back. He was single. His lower lip was still tucked between his teeth as he closed his eyes. He knew that breaking up with Kurt was the right thing to do. But, Jesus did the right thing to do suck sometimes.

XXXXXX

Sebastian cursed as he missed his cue, again. Ever since the stupid sing off three days before, he hadn't been able to concentrate.

"Just go apologize to him!" Nick snapped at him, earning himself a glare. Sebastian knew he should do just that, but two things were stopping him. One was that stupid boyfriend that was probably constantly at his bedside, singing him stupid songs. Two was Sebastian's pride. He refused to admit he was in the wrong.

"He shouldn't have gotten in the way," Sebastian ground out in response. He took a deep breath before speaking again, in a milder tone. "Let's just run it again.

Most of the Warblers exchanged looks, but didn't push it. They just shrugged and ran it again.

About thirty minutes later, it was apparent that Sebastian wasn't going to get anything worthwhile accomplished. Cursing his stupid pride, he pulled out his phone. Scrolling through the contacts, his thumb hovered over Blaine's number. He contemplated calling him, but knew it would be too easy to lose his nerve and hang up. So after a couple moments to calm himself, he placed his phone back in his pocket and grabbed his bag.

"Practice is over," he called over his shoulder as he walked out of the common room. "See you tomorrow." He didn't bother sticking around long enough to hear their replies.

The forty minute drive to the hospital was nerve wracking, to say the least. Sebastian thought of about five different scenarios, all ending badly. He knew he had been a colossal jerk to Blaine. To everyone really, though he usually flaunted his nature. It was easier that way, keeping everyone at arm's length. For whatever reason, Sebastian had developed honest feelings for Blaine Anderson, and he hated it. Things were so much easier before, when he was just looking for a good challenge. But then the boy had to go and somehow break through some of his walls, without even knowing it.

And what would he even say to Blaine when he got there? 'Hey, sorry for almost blinding you, I was attempting to humiliate your boyfriend. 'Yeah, that would probably not end up well.

Sebastian was still inwardly panicking even as he asked for Blaine's room number, and as he went up the elevator, and as he walked down the hall. When he reached the correct door, he froze. Now what?

Sebastian took a deep breath, plastered a smirk on his face, and opened the door.
