In one episode, Rachel is in the rewards room bathtub, where she takes an electric toothbrush from beside the tub; at the same time, Tim is shown sitting on the lounge, and the scene implies she used the toothbrush to masturbate. Tim becomes rather awkward because he's aware that she's playing with herself (you can hear the vibrating sound). A really cringe moment in the show (and this season was already cringe when it came to its sexual content).
