As Sam continued to drink, he could detect a faintly annoying buzz in his ear. It was getting louder and louder, interrupting the feel of how much stronger he was getting as the warm blood flowed through his insides. Sam tried to ignore it, but it kept coming at him. Little words, forming in his ear, trying to keep him from taking what was his. Sam bit down onto Ruby's arm even harder, greedily protesting. He would take what was his. He would take it all, that little buzz be damned if it tried to stop him. Sam felt like he was taking the best kind of drug; he felt like nothing could stop him, he was unbeatable in every single way and, damn it all, that felt good. It always felt good in the world where he seemed incapable of winning in this fight against Lilith, it always felt good when he had nothing left but more running around and pointless searching to do, and it sure as fuck felt good when he had been nothing more than drained empty, exhausted, and hungry before Ruby had arrived. Ruby. The irritating buzzing in his ear. That's what it was, he realized, even though Sam honestly didn't want to. He tried to ignore the sound of her voice, still clinging to Ruby's arm like a wild animal trying to keep any outsiders from taking a bite out of it's prey. Her blood was his blood. Ruby knew that. Why was she bothering him? Why was she asking him to stop? A rush of fury darted through him, suddenly making him more like that wild animal than ever. Ruby was trying to take it away. No, he wouldn't let her do that. What right did she have? Who did she think she was?
He would have continued to drink at her arm in frustration in spite of it all, but that last sentence made Sam snap in a flush of rage. Sam's mouth left her arm, dark eyes flashing dangerously as he grabbed her shoulder with a large hand and mentally sought out the demon within. Sam found Ruby - the real Ruby, the black smoke that animated the body beneath him - and squeezed at it tightly, every instinct of his screaming for him to make her suffer for daring to get between Sam and what was truly his. Blood dripping down his face, the hues of his eyes having grown a dark, demonic color, Sam looked so far gone from himself that it might well not have been much of a shock to anyone if he actually decided to go through and attack Ruby on the spot. He was determined to do so, too, right up until a tiny voice in the back of his head thundered out a protest; not Ruby, it growled, not Ruby.
It was right. Sam couldn't hurt Ruby. And that, Sam realized as he finally began to focus on how pale and weak she looked, was exactly what he had been doing. That was why she had asked him to stop. He had been killing her. Sam's eyes went wide and he immediately let go of his hold on her, both physically and mentally. "Ruby?" Sam started uncertainly, sitting upright on the bed in a state of both panic and confusion. He had taken too much. The words that had been buzzing in his mind began to take form and Sam immediately grabbed Ruby by the waist and hauled her into his arms. He dragged her up so that he was sitting upright against the headboard of the bed, one hand reaching out to sweep her legs to the side as he pulled her into his lap. Sam put a large arm around her shoulders, positioning Ruby so that she'd be able to rest her head against his shoulder.
"Look at me," Sam urged her, that panic flooding through him catching in his voice. He was afraid. Sam was terrified. He had never seen Ruby this way before and it scared him more than he could handle. What had he done? Why hadn't he stopped when she asked him the firs time? What was wrong with him? "Focus on healing," he insisted, cradling Ruby closely, "you gotta focus on healing. I won't take anymore, okay? I'm sorry. I swear, I didn't mean to go overboard with it. I don't know why I didn't -" Yes, he did. He had been greedy. There was something seriously wrong with him. "- I'm sorry. I love you, I didn't mean to hurt you; if I had known that this was hurting you, I'd have never..." Sam gripped her tighter. "I won't take anymore," he repeated shakily. "I swear I won't take anymore."
