If anything, it was rude of Rey not to return the favor. Maybe she could have tried if he hadn’t vanished. Good thing she didn’t vanish, though, I guess.
I think it’s funny that Ben pretty much dies three times in the film.
I’d say it’s probably best if you don’t think about things too much with TRoS, but that’s not a luxury a faneditor has.
