People have lives that he's not a part of? That's a weird concept, why would that happen.

As Joker grabs another book, Strange tries to yank that one away from the angel before realizing well fuck, he can't do this all day. He needs to read these, after all, not just hoard them and glare at Joker.

"...fine," Strange eventually admits, as he turns back to one of the books closer to him. "But I reserve the right to take the book from you should I need to cross-check something!" Or if he wants to be an ass for the sake of being an ass. Either/or.
