You watch them together. You probably could have had him at any point you ever desired months ago. But you'll never know now because Kurt is Puck's now. Maybe you used to have Kurt at some point, ages ago, but he'll never be yours now. He'll always be Puck's. Because even you can see that Puck was the one to pick Kurt up when he was down and rise him up again. And Kurt loves him for that, probably more than he ever loved you. You faded out of his eyes the day you rejected him, the day Puck confessed to him.

(You never should have done that.)

Puck made sure that everyone knew that he had Kurt the day he started going out with him. Puck carries Kurt's books to all the classes (no matter how much Kurt protests) and, at Kurt's request, he even let's Kurt pick him out "decent clothes" (a designer shirt here or there). He never let anyone change anything before Kurt, no matter how hot she was. That kind of means a lot.

And Kurt returns everything (tenfold, but that might just be your opinion). He looks at Puck like he's the sun or something, all adoration and love (he used to look at you like that). Kurt holds Puck's hand constantly; he even lets Puck mess up his hair. He can kiss Kurt whenever he wants (and do more, if the hickeys on Kurt's neck are any indication), no matter who's there or what's going on. The first time you ever saw was when Puck practically molested Kurt after a winning kick. On the football field. In front of everybody, even Kurt's dad. And that man scares you by just existing; imagine what he would do to anyone that hurt his son. Like all emotionally and stuff. He'd probably kill him and make it look like an accident. You think he could.

You could've had that. You could've had the kissing and the hand holding and just Kurt. But you gave it all up, gave him up, for Quinn. You let Kurt go for Quinn, who cheated on you with your best friend and said nothing. Quinn who lied to you, made your best friend lie to you, who almost ruined twelve years of friendship all on her own.

(She should be a lawyer. Or maybe a politician.)

And now you think you might know how Puck felt back then. How he thought you took everything he ever wanted. Even if you didn't, you can still get why he had to blame somebody (you). You had the girl(s) he wanted; he has the boy you want now. You had the baby; he's going to (as of now) get the baby when she's born. You had the guy he liked (loved) pining after you; he has him all to himself. He's got everything (mostly Kurt), and you have nothing.

And you still can't help but think about your best friend's boy.
