Lance doesn't miss the gesture and presumes he's probably reaching for a hidden pendant or something; if he's religious, which is seems like he is from that answer, then having a necklace or other symbol of faith is pretty common.

Right, the whole 'living battery' thing. It's... Not something Lance is super fond of, but he's been mostly ignoring it due to much more pressing issues taking his attention lately. "I have a friend who would feel very similarly." He says, after a moment, thinking about how Booth would take this; he'd hate it, probably, and potentially feel like he's betraying God by providing power to the deities here, even though there's nothing he can do about it. "The gods here draw their power passively, right? So any time we feel one of the emotions they want, it gives them energy without us doing anything more than that?"
