"The birthday wishes aren't necessary, but thanks anyway," Barnaby responded to Jack with a shrug. The cake was the most important issue here, especially since Kotetsu had spent who knew much on it, and Barnaby wasn't going to be responsible for finishing every last piece.

Come to think of it, he wasn't sure what he thought about Kotetsu's idea of inviting a spirit to eat some of their leftovers, but so far Jack hadn't given any indication that he was incapable of enjoying food. Still, Barnaby watched their exchange, mildly curious about whether the boy could help with their problem.
