Sounds like a vague enough answer that Rey isn't picking up what AJ is putting down. Her eyes remain narrowed, but it's mostly because she has no fucking clue what she's doing here.

Well... no sense in beating around the bush. Rey hasn't made a move yet. It's an awfully patient woman who's just going to stand around and wait for AJ to make the first move... and AJ doesn't want to give away that her experience with fighting is mostly nuances of 'shove hard and run like hell'.

"Why the fuck am I here? Who brought me? Why do you care?"
