Christy was rather happy with the news at first, nodding proudly at the fact that Billie had fought at her side against the Charmed Ones, and that the two of them had done what they had always been destined to do. So what if they had died, she found herself thinking, they would do better next time. Then, Christy came to a halt upon Billie's admission that after successfully killing the Charmed Ones, she'd gone back and prevented it, and changed her mind about the entire thing. Her lips pulled into an angry snarl. "You...you...how could you?"
She looked up at the dark sky above, breathing heavily to calm herself down. "You turned your back on the Triad, you turned your back on me, and then you killed me. You ruined everything." She had to resist the urge to stalk off in anger but there were other details she needed to know, other questions she had. "You killed the Triad, Billie. You sided with the Charmed Ones against me!" She couldn't believe the turn the future had taken but it had to be stopped. She would destroy the Charmed Ones now and either she would sway Billie to her way of thinking or she would get rid of her, that much was simple.
