Well, my base level of fuckedness for both of them is pretty high. So far the WS has failed to jawdrop at her coldbloodedly executing an enemy agent, that's business as usual for him at this point, so I doubt he'd care about whatever shocking revelation Whedon put in the movie about her training; it's the little ways in which she doesn't know how to be a child that's weirding him out, especially since he has to teach her to pass as one.
