When the door flies open and his brother appears in the door like an avenging angel, armed to the teeth, Sam sighs in relief.

"Who's that? What's going on?! Is he another gunman?" The girl says.

"That's my brother. He's here to help." Sam stands as Dean ducks, the bullet grazing his upper shoulder. Sam holds up his pistol and shoots the man in the back to the gasps of surprise of his classmates. Dean holds up his shotgun and shoots the second man in the shoulder. Sam steps on the desks, hopping from one to the other while his classmates under the desks yelp at the thumps. When Sam is about two rows of desks from the front of the room the last gunman turns to Sam. Sam quickly holds up his gun, shooting him in the leg. Dean turns to Sam, who is still standing on the desks.

"Sammy! You okay?" Dean examines Sam, his eyes sweeping up and down his body.

"I'm fine Dean. You're not. You're bleeding."

"It's fine. I've had way worse. Hell, it's barley a graze." Dean glances at the wound, blood streaming down his chest. Sam quickly dismantles his pistol, finding it empty. His classmates and teacher gape at the 15-year-old skinny kid, holding a gun like he was born with it in his hand.

"My guns empty." Sam says. Dean pulls a pistol out of one of his holsters and throws it to Sam. Sam checks it and nods in approval.

"What, you doubting my skills now Sammy?" Dean watches him check the gun.

"No, I just-" The door swings open, revealing a mob of men with guns. Sam jumps off the desk, ripping the machete out of his sheath. He takes up a fighting stance. A man fires a shot and Sam bats the bullet out of the air with the machete with more speed than any 15-year-old boy should have. Sam steps menacingly towards the man, but the man is shot down by Dean before Sam reaches him.

Sam turns to Dean. "Really, Dean?"

Dean shrugs his uninjured shoulder. "Hey, what was I supposed to do?"

"Uh, I don't know, how about let me handle it?"

Suddenly Dean barks an order. "Drop!" Sam reacts automatically, dropping to the floor and rolling to the side. Dean shoots. Sam hears the thud of a body hitting the floor. Sam stands quickly.

"No fatal wounds, right? They are just humans." Sam reminds his brother.

"Yeah, yeah." Dean waves his hand dismissively. The door flies open again and Sam turns, prepared to shoot. He pulls the trigger and is met with the clunk of his gun jamming. He drops the gun and holds up the machete. The mam steps closer and Sam steps back, hesitant to cut a man who won't heal like supernatural creatures. He backs up until he and Dean are standing back to back. More men come in and Sam and Dean fight, working like a well-oiled machine. When one Winchester's attention is taken the other watches his back. Eventually the room is left with bodies littering the floor, all of them breathing shallowly. Dean walks to the door and checks outside in the hall, seeing no more men. He walks back to Sam.

"You okay?"

"Yeah, Dean. I'm fine. I don't know about them though." He nods at his classmates and teacher.

"Hell, why do so many people care about a school?" Dean looks at the teacher, hoping for answers.

"Uh-uh- There's a safe. W-with more than a million dollars." The teacher stammers shakily. Dean rakes a hand down his face.

"Dean, you're hurt." Sam points out.

"Sammy, I told ya, it's fine. You've had worse than this." Dean waves Sam away and pulls off his jacket, pressing it to his wound. The sound of police sirens fill the air.

"Shit, the cops. We've gotta go Sammy."

"But Dean, school."

"I know kiddo. But dude, cops and hunters don't mix. You really think you can stay at this school after this?" Dean makes a wide sweeping gesture with his arm. Sam looks at the shocked faces of his classmates who can't believe they're having an argument here, surrounded by bodies, like they do this every day.

"I guess you're right…"

"As usual, Sammy. Let's go." Sam hurries down the isles between the desks and grabs his bag. With one last glance over his shoulder at the school he only arrived at a couple of hours ago, Sam and Dean close the door behind them with the resonating thunk of finality. Somehow they managed to get out of the school unnoticed, and no one ever saw Sam Winchester and his older brother again.
