Do you think I want to die, Dean? I'm scared. I'm scared as hell. What if it doesn't work out like Cas said it will? What if I can't handle it?
I'm having these thoughts every day, and I'm afraid if I stop to think about how good we have it here and how bad we're going to have it back there that I'll change my mind and just let the apocalypse come, but I can't do that. This is my responsibility and I have to take care of it! [Voice filled with emotion.]
