John is propping up a wall when he senses movement, then spots the the young man finding a place of his own, just barely in John's periphery, still and silent.

He lets it happen. The kid moves like a fighter, but not quite like a soldier--not like John's kind of soldier anyway. After a few moments he turns his head just enough to get a better look...

That expression he wears makes John ache inside--raw and bleeding. He's a fucking kid.

Pushing off the wall, John moves into the kid's line of sight, catches his eye, and jerks his head for the kid to follow him--specifically, over to the tables where there's food.

The best place to start with any kind of wounded animal, especially the human kind, is with a full stomach.
