Hi. This is my first post here. After you read, please review.

Warnings: There is a bit of bad language in here.

Perhaps for the first time in his life, Sam Winchester saw red. Usually, he was a calm and somewhat passive person by nature. In the many schools of his childhood and even in college, he was known for talking things out rather than using his fists. Sam had always felt his nature balanced his brother's. Dean was the one that used his fists to communicate. Sometimes this worked and other times it didn't. When Sam's words didn't work, Dean's fists did.

There were times when Dean's anger became all consuming. Most of the time, Dean would quit fighting at their father's voice or even the voice of a teacher. Yet, when the all consuming rage set in, only the voice of Dean's Sammy could snap him out of it. Sam had once asked his brother what it was like when this happened.

"A haze falls over me. Sounds fade away, so do other people. My heart pounds in my ears. My focus is on just the person I'm fighting with. Your voice brings me back. Do I scare you when I'm like that?" was the response given. Sam then told Dean that, "No. I know you would never hurt me." This was the truth.

Having never experienced this sensation before, Sam had always wondered what it felt like. He had no doubt that it happened just like Dean said it did because his brother never lied to him. However, knowing what it was supposed to feel like and actually feeling it are two different things. One night, Sam finally got his own experience.

Late one evening, a stupid drunk ran a red light and crashed into the Impala. Both the intoxicated idiot and Sam had walked away with minor bumps and bruises – although they still had to go to the emergency room to get checked out. Dean hadn't been so lucky – he had gotten some broken ribs and a broken arm. Sam now sat in one of the uncomfortable ER chairs waiting for Dean to be released.

Just then, the man who smashed into them came walking towards him with another man, heading for the door to the hospital. The bastard was smiling. All the things that were just below the surface – the fear for his brother, the raw powerful anger at the drunk – just came to a boil. This selfish asshole could have killed Dean. It happened just like his brother had said. The haze descended, the noise of the ER disappeared, and his heart beat loudly in his ears. Before he realized or even thought about what he was doing, he tackled the still slightly drunken man. After grabbing a fistful of hair, he began punching the guy over and over in the face.

Later, Dean who had just arrived in the waiting room to get Sam, told him the entire time he was beating the hell out of the guy, he was shouting. For the life of him, Sam couldn't remember what he had said. But Dean would never forget.

"You stupid son of a bitch, you could have killed him! He's the best thing in my world. The only thing I have left. My hero. Can't live without him. Drunken bastard!"

Dean was right about one more thing – all it took for him to stop was the sound of one voice saying, "Sammy, stop."
