Aziraphale sets down his spoon and pulls out a business card from his jacket pocket. He hands it to Molly, detailed calligraphy on one side reading, A.Z. Fell & Co. Antiquarian and Unusual Books with a London address below. The other side has a short sequence of numbers that fades into existence before Molly's eyes. "That's a number you can use to contact me once you obtain a PINpoint. It's a device that lets you travel between worlds. I'll make sure you get one if you haven't already."

That settled, he returns to his meal while keeping up with one of his favorite topics of conversation, his face lighting up at the proposition. "I'd be delighted. I'll spare you my entire routine as I don't have my props with me, but I always keep a deck of playing cards on me, should the occasion present itself. And if there are any tricks you'd like to teach me, I'd be most interested."

See, Crowley? Stage magic is fun, even to those who can do real magic!
