Dean Winchester: Back at the hospital, you know, full recovery. It was a miracle. And five minutes later, Dad's dead and the Colt's gone. You can't tell me there's not a connection there. I don't know how the demon was involved. I don't know how the whole thing went down, exactly. But Dad's dead because of me. And that much I do know.

Sam Winchester: We don't know that. Not for sure.

Dean Winchester: Sam... you and Dad... you're the most important people in my life. And now.... I never should've come back, Sam. It wasn't natural. And now look what's come of it. I was dead. And I should have stayed dead. You wanted to know how I was feeling. Well, that's it. So tell me... what could you possibly say to make that all right?
