Even though she's been confronted with supernatural creatures, angels, alternate universes and goodness knows what else, Abigail's still rather getting used to it all, so she just assumes that this guy is making a joke. Probably trying to help with humor, but she's not in the mood to be charmed.

He really doesn't seem to be giving up all that easily; Abigail looks at him, suddenly more shrewd than short-tempered.

"Let me guess, you're feeling an urgent need to cheer people up, or something like that?" There's scorn in the way she says it, but all the same, she won't deny that talking to him is, just barely, better than wandering around alone entertaining disturbing thoughts. So, with a somehow distinctly teenage sullen reluctance, she admits, "A distraction might be nice, but there's nothing to do around here."
