Thank you. I have been wracking my brains going - who is that? I feel seriously ashamed. And me a Star Trek geek. But then I didn't look at the credits but still. . . . everytime she said something I'm like - I know this person, who is this? Shame, shame on me.
Dean: Who are you? Castiel: I'm the one who gripped you tight and raised you from Perdition. Dean: Yeah, thanks for that.
