God, this was so wrong... he was drinking down his brother's blood like it was good, but he did feel better, felt the effects and felt himself healing. Eventually, he forced himself to pull away, not sure how much to take and some part of him was nervous about the effects. He didn't know what to expect... knew what happened when you drank it from dealer's, but straight from the source? He felt fine though... better than, really. "Mnh.... Dean--"

He didn't even know what to say as he looked over his shoulder at him finally, mouth smeared with Dean's blood and brows furrowed in concern, maybe a little scared under the haze because dammit, what did he just do? "You okay?"
