She becomes his property

"How do I know you won't take that tape public?" she asks him, not wanting to go for it just yet.

"Simple answer, Selena. I own this tape and I own you. Your life as you know it is over. And so are your friends' lives. You're all going to be my property from now on. If any of you ever refuse to do what we ask of you, every tape we have will be made public."

"Mark..." she asks, hoping he can bail her out of this.

"I'm afraid there's no other way Selena," he tells her as she gives in and accepts the terms of the deal, basically becoming a ho, and Buck her pimp, at that point in time, his dreams of a celebrity prostitution ring about to come true.

Now all he needed to do was tell Selena the first names on his "hit" list.
