(You are Dean.)

Castiel is explaining to Dean about the deal he took to save Jack. "I always wondered... ever since I took that burden, that curse, I wondered what it could be? What my true happiness could even look like. I never found an answer because the one thing I want... it's something I know I can't have. But I think I know... I think I know now. Happiness isn't in the having, it's in just being. It's in just saying it."

"What are you talking about, man?" Dean asked.

"I know. I know how you see yourself, Dean. You see yourself the same way our enemies see you. You're destructive, and you're angry, and you're broken. You're "daddy's blunt instrument." And you think that hate and anger, that's... that's what drives you, that's who you are. It's not. And everyone who knows you see it. Everything you have ever done, the good and the bad, you have done for love. You raised your little brother for love. You fought for this whole world for love. That is who you are. You're the most caring man on Earth. You are the most selfless, loving human being I will ever know." Cas is starting to cry. "You know, ever since we met, ever since I pulled you out of Hell... knowing you has changed me. Because you cared, I cared. I cared about you. I cared about Sam, I cared about Jack... I cared about the whole world because of you."

Cas laughed quietly. "You changed me, Dean."

"Why does this sound like a goodbye?" Dean asked, getting nervous.

"Because it is." Cas paused for a moment.

Dean opened his mouth to argue.

Cas smiled, tears in his eyes. "I love you."
