[Moonshade lets out a bit of a startled laugh at Kavinsky's question.]

Wrong question. 'Supposed to' sounds like there's someone assigning work to people, but there isn't. There's no chief here. People see a thing that needs to be done, and they do it, because they can.

For example, back home I'm involved in hunting and tanning for my tribe, and I do that here too--though I'm also working to help Lark get fiber to spin into silk. Those who know technology work with that. Cobb's fixing some of the broken houses enough to live in. This is a tribe made of people who don't belong together, but we only get by if we all work together.
