I'm afraid I can't answer this question without more detail. More dirty, perverted detail.

Ahem

Seriously though, what does the fiction suggest? Like, with what who was doing what to who, who got fucked and who just got screwed?
If it's really just an all four pile on and have a grand old time, maybe the Battlebabe does nullify everyone's power. What could have been totally -weird- is all of a sudden okay because the Battlebabe just doesn't care, so no one else has the emotional leverage to get all screwed up about it.
But if like, Marie is all about Drake and was hardly even paying attention to the Battlebabe (regardless of what was going on anatomically) then maybe Marie and Drake still hit each other because in the middle of an orgy they were actually having sex while everyone else was just doin' it.
Personally, if it wasn't really clear from the fiction, I'd probably ask everyone. Like "Marie, was that just some good dirty fun cause the battlebabe kept distracting you, or are you all up in Drake's brain now?"
