Sam Winchester

You know, I've been remembering things, little things, so clearly ... you used to read to me, uh, when I was little, uh—I mean really little, from that old, uh, classics illustrated comic book, you remember that? Knights of the round table! And all of King Arthur's knights—and they were all on the quest for the holy grail, and I remember looking at this picture of Sir Galahad and he was kneeling, and light streaming over his face, and I remember thinking um, I could never go on a quest like that, because I'm not clean. I mean I was just a little kid, but you think—maybe I knew? That deep down, I had demon blood in me, and about the evil of it, and that I wasn't ... pure. It—doesn't matter anymore. Because these trials. They're purifying me.
