"Dean, move over," Sam begged.
"Sammy, you have your own bed. Get off mine," Dean rolled over and ignored his brother. Sam just pushed Dean to the other side of the bed. "What the hell is wrong with you? We paid for two beds for a reason!"
"Look," Sam pointed at his bed.
Dean looked. The blanket was pushed to the side revealing the brownish stain covering a large part of the sheet. He sighed.
"Fine, I'll share. We're establishing a treaty line right here," Dean indicated an imaginary line down the middle of the bed. "Cross it and get your ass kicked."
Sam grinned as he climbed into bed and pressed his cold feet to Dean's leg. "Oops. Where's that treaty line again?"
"Wanna spend the night with mystery stains? No? Respect the treaty line. I WILL kick your ass."
"Night, Jerk."
"Night, Bitch."
