Based on speculation that Blaine has a solo in Guilty Pleasure

"Just so you know
This feeling's taking control of me
And I can't help it
I won't sit around, I can't let him win now
Thought you should know
I've tried my best to let go of you
But I don't want to
I just gotta say it all
Before I go
Just so you know."

"That about Kurt?" Sam says walking into the choir room behind Blaine sitting at the piano. Blaine looks up, slowly eyes shining with tears. Shaking his head, Blaine replies with "It's always about Kurt, but he's got Adam and... I just don't know what to do any more. He told me we were just friends, but how am I meant to just be friends with the love of my life when he's trying to move on and I know we're meant to be together."

Sam, while sitting down at the piano next to Blaine looks over at him and says, " I know that, you know that, if you and Kurt are meant to be together it will happen next year, you've applied to NYADA and your call back is in 2 weeks, you've only got Graduation stopping you."

Blaine standing from his place at the piano chair gets up, and goes to collect his bag " What if I'm not good enough, what if?
"No, Blaine, you're you. You've got your whole future set out for you, you're a straight A student, you've practically joined every club there is in this place, you're our Student Class President for gods sake. You've changed this place completely. Do we get bullied any more? Do you get gay slurs thrown at you like you used to last year? You changed this place, you made it safe for people like you, for this entire Glee Club. So do not for one second think that you're not good enough. You've practically got it made, the only good thing I have about me is my looks, and my impressions, and my killer abs." Sam adds on jokingly.

"Sam, don't think like that, you know that's not true, so what if you don't know what you want to do, look at Finn, you don't need to decide straight away." Blaine adds on reassuringly, "besides, your killer abs did saved you when you really needed it, and killer abs they are." Laughing, Sam and Blaine slowly go to walk toward the door when Blaine starts to speak while Sam turns around, "Sam I need to be honest, you know how you told me your guilty pleasure was collecting Chapstick, and I told you I would tell you mine later, well."

"You're my guilty pleasure." Raising an eyebrow, Sam gestures for Blaine to continue, " I know you're my best friend and you're not gay, but god, that song was for you too."

Laughing, Sam walks toward Blaine to pull him into a hug, " I completely understand, I mean with Kurt gone, I really am the hottest piece of ass there is here, and I know you're not going to do anything and it isn't going to change our friendship."

"So, you don't think I'm an idiot?" Blaine replies carefully, " Did I not just give you a lecture on how you're not an idiot Blaine? Honestly, you're my best friend, you think I'd miss the chance to call you up to talk about the poster for Iron Man 3?" Sam laughs while pulling Blaine toward the door, "Come on we've got History with Schue and he'll only let us be so late without being mad."
