Why was Billie doing this to her? Talking about her life like it was a mistake she'd been taken. Oh she knew how her sister felt about Dumain and the demons that had raised her. Christy hadn't much cared for those demons, but Dumain, he'd helped her hadn't he? He'd wanted Billie and Christy as allies. The Ultimate Power like Billie was saying. She was, as her sister assumed, shooting a look of utter rage toward the Charmed Ones. Or two of them anyway. Now there were four here? All four. Maybe she could use that, make Paige think she wasn't wanted. Or Prue. Prue might be easier to get to. The one that was dead back home. It was one to think of for later. Right now she kept up the decidedly haughty glare. "Rival nothing, we're stronger. Together we're unbeatable, and whatever happened me when I was a child I understand thats how its supposed to be. We're supposed to be better than you. Not that its hard" she said coldly looking back to her sister. Billie had turned on her, she'd looked at her when she'd said what she did with such shock. Not even anger. It had just been shock. Like she'd thought everything had changed, and for a while it had. But it had been Piper's fault. So much of what had happened had come down to Piper and Leo.
"I suppose you want me to say sorry. To her of all people. And I'm not still following the Triad. If you want the truth, they had to listen to me Billie. Me. I was the key. I was the one they had to follow, don't you see. We don't need the Charmed Ones, even in this world. Couldn't it just be us, no Charmed Ones, no Triad, no...no Dumain. None of it." She'd love it, just her and her sister and their power. The demons here wouldn't know what had hit them. Even Lilith, she truly believed they could take on Lilith if it came to that. More likely though some kind of alliance for surrvival after everything happened. After this demon king walked the earth. She'd find a place for her and Billie. She always did.
Christy was a strong candidate for stokholm syndrome if nothing else, not that she knew what that meant, and even if she did she'd deny she was anything like that. She didn't believe she was still following demon orders, long since dead demons at that. All she knew was Piper had put her and Billie through a lot. "She did a lot Billie. It's her fault you turned on me. And you did, I know you did. You let the Triad be vanquished. Forever. You let that happen right when we were so close. And Piper got to you didn't she, with her meddling. She never forgave us for taking Wyatt's magic. Or me, right. I got the blame." It seemed more likely that way. Billie was practicly an honorary Halliwell. "You're my sister Billie. Not hers, not theirs. Why can't you just trust me"
