He was in control. Definitely. He was a tiny bit confused by the way that he was feeling now, because Sam had never felt anything quite like this before, but he knew that he was more than in control of himself and his actions. Ruby had given him access to something powerful and he was the one using it, carrying it inside him, wearing that wonderful feeling that came along with it. If he didn't want to do anything with it, he sure didn't have to. Ruby had asked him to do this now. Hunting down a vampire or two to test things out. Just like she had asked him before, to try this. Why had he waited so long? What the hell had he been thinking, missing out on this?
It scared him. He couldn't deny that. There was a fear buried in his chest, one that was still very wary about the blood that he had in him turning on him. It was not, however, the dominant emotion. The thrill of it all was what was the more focused on feeling. He didn't want it to stop.
"Then let's start hunting," Sam said eagerly, moving forward. He doubted that it would take very long to find what they were looking for. Ruby had cut up her arm pretty good. The scent of her blood was bound to lure something in.
