And it also makes the mention of one kid stand out. Especially as Bigby tries to think about whether he's seen anyone that young, and he's pretty sure he hasn't, even though he's been all over town already in the past. It makes him frown, wondering if he's missed anything.

They can speculate about the kids thing in a moment, but now he first has to ask: "What did the kid look like?"
