It was how it was used. In a show where Fritz and Simmons are sleeping together you could have shown Jemma slipping hers back on to emphasize they were a sexual couple and say 10 o'clock now folks rather than just a gratuitous shot of your star or her hired double.I find it amusing that the discussion about Ms. Bennett's unclothed buttock(s) has gone on for a 30,000% percent longer period of time than they were on screen.
