I have another take on the CM undies scenen the first time I didn't understand why she was asking Kirk to turn around and looking at someone you're talking to is a natural thing to do, I was wanting Kirk to turn back because I wanted to see what she was up to - I was surprised to find she'd stripped off and I thought Kirk was also surprised and after a moments gobsmacked bogglement turned back at her order. They were in a shuttle with the door open, at least a semi-public space, she wasn't carrying a change of clothing or did I see one in the shuttle and those overalls are meant to go over the regular uniform (yes she was in a dress, but it's short enough to fit under the coverall). If for some reason I needed to change in a hurry in the middle of a discussion with someone I'd at least say "I need to get changed, please turn around". I think Alice Eve was also of that opinion - she made a comment about her character stripping off in a corridor during a cast and director interview in London. JJ squirmed a bit... I thought it was there for the titillation alone, to me it's implausible and doesn't say anything convincing about either of the characters to me, which is why it bothers me.
