Sam didn't believe that Meg would cooperate. She wanted out of that truck simply because she believed that Sam was clumsy enough to let her get away from him the first chance she got. Meg had forgotten something, though: Sam knew her. He was no amateur to hunting, nor was he new to her and her ways. Meg wasn't going anywhere. "If I destroy the body, Ruby will find another. It'll be a loss, but we'll recover from it. You, on the other hand?" Sam pressed the knife against her throat even more firmly. "You won't. There's nowhere for you to go once you're dead, is there? It'll be black. It'll be quiet. Or maybe you'll be shot someplace else entirely. It's gotta be worse than Hell if you're begging for a one-way trip down there instead. So." Sam tilted his head to the side quietly, noting that the blade had been pressed to her throat enough to make a little path of blood drip down Meg's neck. The demon blood. It was a big part of why he had gotten screwed into this mess into the first place. Sam had gotten hooked on it, Meg had been able to slip her way right between him and Ruby, and he had ended up killing a woman and letting Lucifer out of his cage because of it. His heart told him no. He didn't need it anymore. It was disgusting, it was foul, and it was the one thing in the world that had destroyed everything that he was. The best thing that he could have done for himself right then and there was to slam that fucking trunk door shoot and walk away. Instead, Sam reached out and ran a finger along Meg's throat, smoothing it along the warm, dark blood that was trickling down her pale skin. It was strange treating Ruby's body this way. But that would be remedied very soon.
"You've forgotten something very important, Meg," Sam said shakily, tongue darting out to lick at his lips. One more time. This was it. The most dirty demon he'd ever drink from. For Ruby. All for Ruby. "I've got plenty of juice right in front of me. Now..." Sam nodded to the inside of the trunk, pointing at an old, plastic cup that had belonged to the car's previous owner. He didn't want to know what had been inside of it before. It didn't matter. "I'm gonna cut your wrist. You're going to bleed into that cup for me. Then you're going to tell me how to take those guys down. Exactly how. By myself. If I do manage to find Ruby in there and get her out - alive - I'll send you back downstairs. You know I'm telling the truth, don't you?" Sam licked the blood from his finger. It physically pained him to do so. Meg's blood...ugh. "We like that body. The one that you're wearing. I'd have to send you back to get it for her, wouldn't I?" Sam tightened his fingers around her wrist and glared at Meg coldly. "This is your only out. I suggest you take it while you still can."
