"Hey there." Contrary to Aziraphale's assumption, Crowley waved his hand and greeted Barty relatively properly. For a reason, of course. "Greetings from Bill."

Barty raised his eyebrows. Bill? "Persistent." He'd give him that. He nodded at Crowley. "Want a ride?"

"Nah. Lovely night, I'd rather walk." He had nowhere to go, that was the translation here, so Barty let it go.

"See you around, angel." Crowley waved at Aziraphale. "Don't party too hard."
