No, can't let her off that easy. You release her throat and land a fist into her busted face. Her head rolls for a few seconds as she attempts to recollect herself. It's not unlikely she has a concussion now.

Keep the bitch quiet, don't want to ruin the fun

Let her scream, they can find out what their futures hold
