We see a video of two teen-age boys appearing to rape Rosie in the basement of their school on the night that she was murdered, and a teacher perhaps crossing the line in his relationship with her.
In yet another time-warp, the Act III party scene subjects Senta (who has become a sort of she-wolf by her embrace of the Dutchman's satanic curse) to gratuitous gang rape by the chorus, costumed as characters in some weird video game.
