Meg threw the knife, she had no choice but to throw it, she didn't want to call his bluff on killing her, not in the mood he was in. And he told her she didn't understand the disgusting love thing. She didn't want to. He'd drunk her blood down and she wondered would that be enough as she watched him getting ready to rescue his beloved. Her blood, might not have had the taste of Ruby's but it would do the job. Her fellow demons would die. If she'd cared about any of them she might have shed a tear. As it was they were less than her, nothing special, and if they had to die now then so be it. It wasn't like she could have helped them even if she wanted to. Though she did hope Brady got out. If for no other reason than he'd be useful later. A way to get to Sam when all this was done, and even if she had to crawl out of hell again then she'd do it. She had before, countless times. Meg was nothing if not a fighter. Or maybe she was just stubborn.
Yeah that was probably it.
"Fine, 'Sam'. If you insist." she retorted, "You better get going if you want to save her. She'll be hurting if nothing else. Less than she's used to of course but you've been keeping her all safe haven't you. Telling her she'd never have to suffer like that again. Telling her she'd be protected. Good job there Sam" she teased, Yes, teasing from her current position was probably a stupid plan but she did it anyway. It was worth it. Let him go and save his whore. Least if she did that she'd have a way out of the trunk.
