After Loraine's episode with Ava and Mat a few weeks ago, so went back to her place and secluded herself in her room for the better part of a week, because she felt dirty for betraying her boyfriend. That's why she will not give it up to Sam. Their fun and games are purely for viewership, which equates to money.
When Radislava was notified in mid-April that she was being removed, Loraine started enhancing her Bating episodes, as her role was to in effect, replace Radislava. In my opinion, she has fallen well short of the goal.
