All I can see is Rey-as-Kylo just constantly running into things. Clipping her head on doorways and moving things VERY CAREFULLY so she doesn't knock them over and just generally being a massive klutz because she's not used to being such a fucking giant, until everyone on the Finalizer is starting to wonder what the most polite way is to ask Lord Ren if he's drunk.
