I think Daval likes confrontations, so I think one of the following might happen : Peter will return and see them fooling around in the bathroom. He will either hold this info and try to rape Sarah, at a later date, telling her what he knows, and she has to submit. Or he will walk in on them and get into a fight with Aaron. Or he will try to attack/rape Sarah later, and Aaron will come to her rescue. Just thoughts, but this story never seems to go easy, so I think there will be another fight, at some point.
