"Boiler," she repeats, quietly, and reflecting on the implications briefly. Not a combustion engine, but something in him is making that glow, presumably. Before she exposes her war boys to him for long, she'd like to get a Geiger counter close enough to check him, but that may not be feasible. "Hmm.
