"It's not going to go South, love. They're family." Barty turned around to look at Bill, just about smiling. "Anyway, I have a knife."

With that, he got out of the car, leaving Crowley behind to puzzle over this. "Is he kidding? Does he-- He has a knife, doesn't he?" Just didn't seem as if he'd be bluffing. But what was he going to do with the knife?

He watched as Barty approached the house, knelt down to get a spare key out from under the doormat and then let himself in.

"Hello, darlings! I'm home!" Barty closed the door behind himself, pocketing the key absently as he looked around. "Aziraphale! Get down here!"

He decided to simply make it an order, while he could hear his other siblings scramble around to decide how to deal with him.
