"Well, I'll use my money to support my little brother getting some books that make him happy." Seemed like a much wiser use of his time. Barty sat down as Aziraphale wanted him to, holding the book so he could see and letting him look at it first before he started to read.

It wasn't that long before he realised that Aziraphale was asleep, so he stopped reading, gently setting the book aside. He let Aziraphale sleep tucked against him, because when he tried to move he seemed upset. It was a strange feeling. He wanted Aziraphale to feel safe.
