Dean Winchester, his little brother, Sammy and their "father" John have moved to California. Sammy is starting his Freshman year while Dean is going into his Junior year. They are staying in this crappy and cheap hotel about a mile from the nearest high school which they will be attending. They have only been there for about 3 weeks and haven't been kicked out yet, some miracle. Dean had scraped some money together two days prior to the beginning of the school year, to buy Sammy all his needed school supplies.
Dean was the only one who worked to pay for things they actually needed; like food, clothes (Because Sammy wouldn't stop growing) and to pay the rent. Their father "worked", if you can call gambling that, and used most of they money for his beer and "special friends" he brings by every other week. When John ran out of money he stole from other people, most of the time getting caught and landing him in a holding cell for maybe a day or two.
After that would happen he would steal Dean's hard earned cash. Dean and Sam knew never to bring it up or interfere, last time little Sammy caught him, He had tried to beat Sammy. Luckily Dean had gotten there and had taken, yet another, beaten for Sam. He has and never will regret his chose. He vowed, ever since their mother had died and John started drinking and abusing, that John will never lay a hand on Sammy as long as Dean lived. He'd keep his brother as safe and happy as he could in their condition. In a short term of the story – Dean will do anything for Sam.
