Ezra nods. "Okay," he says, and walks with Spot to the mouth of the allyway where he picks up his stone (it's a good one).

He turns quickly back to Spot, burning with curiosity, but of course he's not going to ask. Not least because Spot probably has more questions and harder ones to answer, because Ezra has no answer.

"Watch your back, okay?"

Well, his front. Just - stay safe.
