Ruby shrugged, Needy could stab her if she wanted. "You stab me you join Bobby on the list of people who owe me new shirts but go right ahead." she said almost amused at the idea. Needy was something different in her own way. Demon tainted without being a demon. But that wasn't the problem now. Now she had something wrong with her beyond all that, the rock. The same kind probably that had messed Sam up. And much as she didn't much like Needy, which she didn't feel bad about. Needy didn't like her, she didn't deserve this. No one deserved to be twisted up by alien space rocks
"Either way Needy, we're fixing you. So give up the jewel or I'll take it" she said simply, a wave of her hand slamming the door behind Needy shut with a loud bang hoping to get the jump on her as she moved in to attack, unsually of course the attack was entirely justifed, even helpful.
She mostly just hoped people realised that and didn't want to kill her. That would be annoying.
