I read Lurie's script for the remake, she's raped by Charlie and then sodomized by Charlie's friend. She smiles while Charlies at it and then cries when his friend is at it.
ETA: I think Lurie made a point of the whole "crying and shaking" thing in yet another attempt to offset the feminist outrage over a woman who enjoys such a vicious attack.
I never understood why everyone says sodomized. Sodomy is sex with animals. What does that have to do with 2 guys raping a girl?
And yes she enjoys the "rape sex" with Charlie but is shocked as he allows his friend to take her as well.
