"It's nothing," John tries to brush it off, but as he sits and eats he occupies as little of the seat as possible and he keeps his head down, looking like he's physically incapable of relaxing.

He'll struggle to finish the meal, but he'll make himself do it anyway, if nothing else out of habit, not knowing when the next time he'll have something to eat might be. Occasionally his head will track a few unfamiliar noises around but he doesn't make a lot of eye contact with Billy as he wanders in and out of the kitchen.
