When the Levee Breaks

Chapter 1: When Did Things Get So Bad?

In a honey-moon suite at a hotel, two brothers were staring at each other intensely. There was a lot of tension between the two. Both of these brothers wanted the other to understand why they were right.

Sam stared at his brother. He wished Dean could just understand.

Why doesn't Dean believe in me? Why can't he trust me? I'm not doing this for kicks! This is the only way we can kill Lilith. I don't like to drink demon blood, but it's the only way I can turn this curse into something useful! Why can't he see that I'm the only one that can end this? I'm not evil, and I won't become a monster. Why can't dean see that... Sam desperately thought to himself. He decided to plead one last time for Dean to not turn his back on him.

"Look, my whole life, you take the wheel, you call the shots, and I trust you, because you were my brother! Now, I'm asking you, for once, trust me." Sam pleaded with his brother. He didn't care how desperate he sounded; Sam needed him to understand.

Dean stared back at his brother with a mixture of anger and despair. Dammit Sammy! When did things get so fucked up? I want to trust him, I do. But this is wrong on so many levels. Why can't he see that the demon bitch is messing with him? And why does he feel like he's the only one who can kill Lilith? And drinking demon blood? What could ever make him think that's okay? When did I let things get so bad? I can't let Sammy turn into a monster. Not my little brother. Dean thought to himself as he stared at Sam.

"No," Dean said, "You don't know what you're doing Sam."

"Yes I do!" Sam said angrily.

"Then that's worse!" shouted Dean.

"Why? Look I'm telling you-"

"Because it's not something that you're doing, it's what you are!" Dean yelled.

Sam was startled as he looked at his brother. Dean wondered if he should continue, and he did.

"It means…" Dean started. Sam looked at him, his eyes watering. "What? No.." Dean cast his eyes down. Why did this have to happen. When did things get so fucked up? What happened to my Sammy?

Sam was shaking in anger and his eyes were watering. "Say it," Sam said viciously.

Dean looked his brother straight in the eyes. "It means you're a monster."

Even though Dean believed in what he was saying, he instantly regretted the harshness of his words. Sam was stricken by the intensity of that short phase. It hurt Sam in a way that no punch could ever. Dean knew the effect this would have on his brother. He could see Sam shaking in anger. Dean just stared at his brother, wishing to hell he could get Cas here to zap his ass back in time, to the better days. He wished that Sam wasn't in so much pain right now. He wished he could fix it. It was his job after all, and he was failing. Dean couldn't help the lonely tear that rolled down his cheek.

A rock hard fist suddenly connected with Dean's face, causing him to fall to the ground. Dean was frozen for a second. Even though Dean's face was slowly swelling from the hit, he didn't notice. The punch didn't physically hurt him as much as it did emotionally. The punch was proof of how fucked up things were between the brother.

Dean picked himself up from the ground and turned to face Sam. He stared at his little brother. Dean knew that if he punched back, it would be the end. Dean knew he could just leave now, with no further harm, but no, he was too angry. He would get through to Sammy, and if kicking his demon-blood powered ass was the only way, well then that would just have to do.

Dean tightened his body as he threw a punch at Sammy's face. He punched him again, then in the stomach and finished with a nice kick to his leg. He pushed Sam away from him and went in for another punch, but missed completely. Sam then started punching him over and over in the face, until he threw Dean against a mirror, causing it to shatter. Dean turned to his brother and threw another punch, but missed again. Sam used this opportunity to throw Dean, causing him to land on a glass table.

The table shattered on impact, and Dean couldn't help but to grunt in pain as he connected with the shards. Dean had an odd, numb feeling in his back suddenly, and his face became surprised. "Sam," he said, with fear in his voice. He saw that his little brother was approaching him menacingly. A pair of his brothers giant hands wrapped around his neck, cutting off the air supply. Dean started panicking and tried to make his brother stop, but he realized he couldn't do much with the shards in his back and the lack of air. Dean stared at his little brother, praying that he didn't kill him. Everything was getting fuzzy and Dean could feel his eyes rolling.

Sam suddenly let go and stood up looking down at his big brother. Dean gasped for breath, but each intake caused searing pain through his body. Sam looked at his brother in disgust. "You're so weak." He said. Dean was still trying to regain his breath, but he could feel something was really wrong with him right now.

"Sammy," Dean said. Sam just looked down at him. "Sam, something's wrong," Dean said, his eyes wide with fear at the terrible sensation he felt in his back. Sam just continued to look down at him with a sneer on his face. Dean looked into Sam's eyes. Why wasn't he helping him? His voice was shaky and desperate as he whispered, "What's wrong with you?" Dean couldn't stop the tears, the pain in his back and his heart were too much. Sam curled his lip at his brother question.

"Go to hell, Dean," Sam said.

The intensity of that phrase, and the look in his brother's eyes caused Dean to physically flinch. His breathing became labored and he felt like he had just been punched a thousand times in the stomach. He scrunched up his face to try and make the feeling go away. Abruptly, Sam turned and left, slamming the door on the way out. The slam of the door pulled Dean out of his trauma.

NO! Dean thought. He needed his brother here with him right now, no matter how fucked up their relationship was, because he knew something was wrong.

"SAMMMMM!" Dean yelled at the top of his lungs.

Sam was walking down the hallway when he heard his brother yell. He came to a stop when he heard, "SAMMY!" come from his hotel room.

Sam had never felt worse in his life. He just told his brother, who had traded his own soul to save him, to go to hell. He clasped his head with his hands and sobbed. He wished to God this never happened. He loved Dean so much, but Sam now knew that he would never understand. "I have to do this," Sam said to himself in the hallway, "After this is all over, and I kill Lilith, I'll make things right with Dean." With that thought, Sam straightened up, and left the hotel, ignoring the shout from Dean, thinking his brother was just being a dramatic. Little did Sam know, there was a 5 inch shard of glass in his brothers back.
