She tries to check on them, but the ring won't let her?

Katie paled -- in all this, she hadn't really thought about what this would do to Cassie and Cara at all. She pulled out her cel phone and wrote a text: "U OK? CALL ME NOW," but the ring froze her before she could hit "send."

Now now, it warned her, let's not interrupt my sisters' fun.

"Please," Katie begged, "they're my friends. I'll do anything you want."

You'll do that anyway, the ring smirked. Besides, why should you care what happens to those bitches? They're the ones who got you into this mess, and it's blind luck you're in the privileged position I've granted you.

"Yeah, they're bitches," Katie admitted. "They're still my friends."
