For all its usefulness, for all his time spent with Mark and the simple plants that used to cover his kitchen at home--he hasn't occupied himself with gardening since his arrival. Maybe it was just the weather, or the lack of pots he was so accustomed to. "So the garden's tended but the houses are filthy," he notes aloud, looking around the overgrown park again.

A puzzle for later. "Anything in that garden to punch up what we're already eating? Nobody seems hurt, but I definitely feel like I need a few vitamins more than I did yesterday."

With the adrenaline of necessity wearing off, he's starting to feel how heavy everything hangs on his frame, and he wonders if what they really need is more to do with fat than vitamins.
