Batman

God bless homework, and then curse it again, because it was both the only reason Bruce got any peace in the evenings, and the second-hardest argument he had with his foster child.

(The hardest was about girls, and it often led into the second, because the first was much, much more intriguing to the boy's sharp mind.)

He paid off his tab as soon as he entered, and, because he was planning to beg for advice, also paid off Zatara's. He sat down next to him at a booth on the far wall, and idly made a bet with himself: pay off the tab again immediately if Zatara brought it up, or let it go for another week if he didn't.
