I bet he didn't share his evidence on the other girl with his boss. So, she'll come out with her evidence trying to use it against him but he'll just use his evidence on the girl to have to claim that she was not raped and that it was just roleplay. The boss will be left stunned and even more cornered than before as now she can't even try using her video or else her own evidence will be used against her. They might get fired for banging in the office, but she'd be fired too and has a daughter dependent on her. I could just read ahead, but where's the fun in that?
