A/N: I was trying to write something else, but then came out and I thought, "eh, why not?".
Here's the thing about Sam.
Sam was born to a family conditioned for war.
He was raised motherless, his first impressions being of fire and tears. He was taught to believe in revenge, gutting and slicing his way through monsters. Home was a foreign term replaced by classic cars and motel rooms reeking of body odor.
Dean was his brother and his teacher and his caretaker; his father was a man of no answers, growling commands, and upheaval.
Sam was told love meant pure sacrifice and obedience.
Sam found himself through a world of exploration.
He was pulled and guided into an isolated world and elbowed his way to society. He learned that other people had mothers, saw the way love could be manifested, and realized that family could come without fear and danger.
He knew that away from the responsibility of hunters was where dreams lay.
Sam fought, not with salt and a sawed off, but with determination and his mind, for a future.
He read the world on pages and pages of books and walked around with knowledge spewing from his tongue. He trained himself to know of feelings beyond rage, love, and terror. College was a step off the road of Dean and Impala and it could happen.
Stanford was his asylum, for a time.
Sam experienced loss of the uncontrollable and expected variety at 22 years of age. He realized the complexity of life was built off of a foundation of family, loss, and action. He past called for revenge and his pain pushed him forward.
Sam cared. He wanted people to be alright and he wanted for Jess to be avenged (alive) and he knew he was built for a different life than most.
His arms were corded with muscles used for hacking, sawing, and digging;
His legs for running, kicking, jumping;
His mind for strategy, coordination, and tough decisions.
Sam was a child turned soldier in past, present, and future.
