Castiel: I’m sorry. I was wrong. And… while it’s true that I didn’t know we were killing an innocent, ignorance is no excuse. I truly can’t imagine the depths of your loss. This was your child. I can’t imagine the pain. So if you leave here and you find that you can’t forgive me… I’ll be waiting.

Lily Sunder: Thank you.
