Lucifer nods in agreement. "I wanted to show you my library today. Now, we have the perfect excuse."

Turning to the shopkeeper he glances at Aziraphale and then inquires about cost. Quickly, he discovers the price is not overtly high and gold is accepted. Then he checks in with the other angel.

"Shall I pay? I have an abundance of unused gold." It was an offer without strings. He was glad to see Aziraphale excited and knew that he was looking to bring happiness to one of the more distraught angels that lived in Lucifer's realm.
