Aw, Jack was talking about people, not monsters. Or, well, monsters that were also people? But mostly people! "Er, thank you?" is what he says, sounding more baffled by the sudden-seeming anger to an innocuous comment. He knows it wasn't meant as an actual wish of good luck but, well, he's not here to be rude, and he'll be polite as long as he can to anyone and everyone.

He makes one last attempt, adding, completely uselessly for SecUnit though he doesn't know that, "If you need any food or anything, I have some at the camper van thing over that way." He gestures the direction he'd come from.
