Update: I just watched an episode of I think it was called Frayline. Basically it is a SWAT team based drama that deals with all the different situations that come up.
Anyways the episode had a girl abducted by a guy who kept her basically as a slave for what ever he wanted. He warped her mind into thinking that her parents wanted her to be safe with him. Twisting the story of Anne Frank to have her hiding from the bad guys that were running the government. So she hid in her attic so the police wouldn't get her. Well when he kidnaps another little girl the police pick up on it. This guy had his house build to connect to an old abandoned brick yard and the house wired. He could tell when people were at the gate to the back yard, windows, doors, and even on the property. He placed trackers on the girls so that when they went to the doors and or windows.
What I was thinking of is someone has a sexual slave/pet and gets another. The original pet gets jealous and is mean to the other pet as she tried to get back her owner's attention while the new pet wants nothing to do with being a pet.
