Sorry ain't exactly cutting it. Adam thinks I 'left'. Not sent away, left.
And you wanna know what happened, Cas?
I went back to Sam. I begged him to go where Adam was, so we could save him, but so many more things came up. We saved so many people... And when we got to Adam, he was already dead. I moved on, and I hunted with Sam, I never let him leave. And in the end, he thought it would be brilliant to say yes to Lucifer anyway. He did it willingly, in an attempt to jump into the pit himself.
The plan backfired, and Adam was brought back for Michael again. Adam hated me, Cas. Hated. Because I wasn't there for him. Then Lucifer blew up Bobby. And he beat me to the ground until Sam finally got control. Then I watched him and Adam take a swan dive into the cage.
Then you were brought back to life again, after being blown up, and realized that I didn't belong there. Bobby was dead, and there was nothing you could do. We never could find my dad, and I was alone.
Then you laid your angelic hands on me, and sent me back here. At first, I thought you sent me down the street, since I was back at the stupid cemetery just moments before. But now I know you sent me back here.
Two god damn years, Cas. And a week here, and the only family I had left who actually gave a damn hates me.
