They have discredited her, she hasn't a chance of winning. To me it looked like he took her and led her to the toilet, but I know I am a dope with a few drinks, and if someone took me by the hand, I'd probably go with them, before thinking about where I'm going. She probably thought they were all going back to his room for a few drinks and a few lines and a bit of a flirt. She may well not have had any intention of sleeping with him. But because her original story of being forced into the toilet doesn't match the camera, she will not be believed.
Poor Dee.
