I think Crystal is a very strange and mixed up individual and there is no telling what she's about or what she'll do.
The very fact that she went back to the pole right away seems very weird to me whether she was raped or is faking.
Well if she wasn't raped then there was no trauma associated with it. For her it's probably just another "lost weekend" - one of many. She met her goal - she didn't get put in Durham Access and was released - so other consequences are peripheral.
She was not rape, and why would she not go back to the pole?
It's her job, this is what she does.
Why would she stop?
