Dean walked towards the couch and started packing his duffel. As he packed he thought about the hunt. Of course! It had to be Bobby who fought on Sam's behalf. Why couldn't Bobby just get that simple fact that they weren't in any shape to hunt right now together. Handling the whole thing alone would have been so much better. And then the topic of trust came up. Trust was as thin as dust these days. How could Sam expect Dean to trust him when he had clearly gone against everything that Dean had ever said? After devoting your entire life to someone, if this is what you got, then he wasn't sure that he even understood the concept of family or if he ever had, thought Dean bitterly. He sighed. The sooner they finished the hunt the sooner they could get back on the road away from Bobby trying to pry and mend things between the two of them. Dean zipped the duffel. He stood up and stretched. He decided to walk back up to Sam's room to inform him that they would be leaving at 9 the following morning. Dean walked up to the door and knocked. When no one answered the door, Dean hesitantly opened the door. What he saw then shocked him to his very core. To watch his brother do something so utterly unthinkable came as a shock to Dean. It rendered him unable to speak. He stood there, appalled his mouth open, his face a mask of disgust and horror. How had Sam gone so wrong? How had Dean screwed up so badly in raising Sam that Sam turned out to be like this? Gradually Dean regained the ability to speak.
By now, Sam had straightened up and moving away from Ruby, he stood there gaping at Dean, his mouth opening and closing like a fish. Once Sam got himself back in control, he started forwards towards Dean and said, "Dean let me explain—"
But Dean was beyond livid now and would listen to no amount of reasoning. Dean's face masked into one of disappointment and weariness. He cut Sam off and said, "There is nothing left to explain. Hell right now, I don't care. I don't give a rat's ass about what you do with that demon bitch. There is nothing left to say now." and with that Dean marched out of the room.
"Dean Wait" Sam shouted but his shout fell to deaf ears. Dean was already out of the room slamming the door behind him. Sam turned behind to tell Ruby off but on turning he found that somehow during the confrontation she had slipped. Sighing tiredly, Sam walked back downstairs to try to convince Dean and to talk some sense into him. Sam ran downstairs only to find Dean sitting on the couch with a hurt and disappointed a whiskey in his hands.
Dean walked back downstairs with a miserable and disappointed feeling. How could Sam do this? Right now, all he felt like doing was drowning him in a bottle of whiskey. And this is exactly what he did. A few minutes later, he found himself sloshing whiskey in the bottle, feeling the familiar feeling of losing himself in the burn in his throat as the all too familiar liquid washed down upon him.
Sam stood in front of Dean apprehensively wondering how to even begin explaining the mess he had made of things. As Sam stood wondering where to begin, Dean said, "Spare yourself would you? I don't want to listen. Not now. Not ever. I don't want to listen to how you got addicted to this damn drug nor how you chose a demon's advice over our principals or how she is practically family to you now or how all of a sudden doing something monstrous as drinking blood is okay to you. So don't try to explain. You can't" Sam choked down sobs as Dean said these words. Dean would surely hate him now. He had really done it this time. If he had thought that the siren was bad then he had had no idea of what would this little secret of his now do to their already shambled relationship?
"Dean you have to understand. I am not choosing her over you or anything. It's just that I have to kill Lilith. I am doing this for you. She has the best leads. It's why I resort to her. And I am not addicted to this blood alright.—"
"Please stop would you. I don't want to listen to your lies anymore. Now really man. I am tired of your lies and excuses. We used to be brothers but you spoilt everything. I am just tired. You can go right ahead and do what you want. Don't mind me. After all how could you? Just who am I in your life. Just a weak and pathetic excuse of a hunter brother. So really you can just stop. I feel like I don't even know you anymore. I don't want to listen to your lies, your excuses just about everything. Tell you what. You can go right ahead and continue your drink with that witch in peace. Don't let me interrupt your 'little secret session cum date'. So just go Sam. I don't want to talk about it anymore." And with that Dean turned away from Sam. Finished his whiskey in 1 swig, he lay down sideways on the couch, his back against Sam.
These words of Dean had hurt Sam worse than anything else he could have said. It hurt to hear your family disown you. It hurt to hear rejection so strong in Dean's voice. It just plain hurt. Tear track made its way down Sam's cheek. As Sam turned back towards Dean, to walk back upstairs, he heard a sob coming from the couch. He turned back and saw Dean still in the same position. Thinking it to be his imagination, Sam turned back and walked right back upstairs. Little did he know that he had just left behind a 30 yr old shedding tears for the only family he had ever had.
