Exactly... EXACTLY! I called this a long time ago... a pathological liar survives on morphing to their surroundings and situations. Casey will take what she has and create a life around it... she may feel a sting at first, but slowly she will observe and work things, until she is just another part of the inmate community. Women in prison tend to be far more forgiving of each other, from what I have read about inmate life... they tend to bind into a tight community... and I can easily see Casey finding her roost and making out well, on the inside. I wouldn't even be surprised if she takes a girlfriend to deal with her physical wants.
She'll probably get one of the male guards to do that for her. Susan Smith was pregnant by one of the male guards the first year she was in prison. Not that hard, she comes on to one of the guards for favors. Easy to do because she's considered a hottie to the guys. I just hope she get's DP.
