"Onyx? That's an interesting name for a puppy." Aziraphale doesn't mind in the least when the puppy bounds over, even when his shoelaces might be in peril. "Oh, well that's all right. Er, not that I want my shoelaces to be eaten, but I'm aware that puppies will be puppies."

He watches Balthazar handle the puppy, his wings on the astral plane relaxing a little. It appears that his angel is as warm-hearted as his alternate. "You're Balthazar, yes? My name is Aziraphale. I'm, ah, friends with an alternate of yours."
