"Devils or demons? There's a difference." Balthazar chuckles faintly. "But be careful saying that sort of thing in front of my brothers. They might get offended."

He laughs at the mention of Donna fancying him, soft and sheepish and mildly pleased. "She's a gem. She really is, and she has no idea how much so. I'm afraid I'll disappoint her before too long, but I admit I'm growing fond."

Donna is so human. She exemplifies all the qualities Balthazar likes in humanity, to be more exact.
