He didn't mean that. He didn't mean he'd kill her, destroy the body he and Ruby loved so much. Nah, he was lying. Of course he was lying. She shook her head but stopped almost immediatly as he cut her. That knife...it hurt more than anything else she could imagine. Actually seeming to cut her deeper than anything she could imagine and he'd drawn blood from her neck. Blood that he now seemed to be staring at again. No, no she didn't want him drinking from her. Even in this body that he had to be used to drinking from. Meg didn't want him to have her blood. He was a monster. She'd seen it. She'd seen what he'd done to Lilith and she'd pretty much written him off as a liability now he'd done his job. His finger dragged along her throat and she knew she probably should cooperate. Better for her long term health and of course, her life. She'd done enough, more than enough for him to have every right to want to kill her. But the blood was something. The blood could be her way out of this, even if it was disgusting.
"Alright fine...give me the cup and a knife that won't, y'know, kill me." she said furiously, watching him lick the blood. Hers, not Ruby's hers. "Maybe you'll feel better for it, remind you od Dad maybe, your first taste." she added, wanting to get at least one insult in. He deserved that and more for what he was doing to her. Because yeah, she knew he was telling the truth. He'd send her back rather than kill her. If he got Ruby back, she'd want her body and for that, yeah he'd have to send her back. "Go in quick, you have to be careful. If you kill you might hit her accidently cause she's not in this body. Once you work out which one she is, do what you do. Then, come back here and send me back." Meg wasn't stupid and she knew this was the only chance she had. Plus she'd very probably pissed him off with the comment about her father's blood.
That's what had started Sam out in the first place, back when he was a baby. Oh they'd all been so excited, every one of them even Ruby. Maybe especially Ruby. "What's you do to her?" she finally asked curiously. "I mean you thought she was me and the way you acted...is that what you're like with her. Ruby was never that weak. How'd you do it?" she asked, wanting to know before he shut her back in the trunk.
