Okay now, I'm gonna start out with the fact that I LOVE DEAN. He's awesome, amazing, incredible. This is just a what-if one-shot, so don't hurt me!

Remember in 'Metamorphosis', how Dean took a couple of punches at Sam? What if he hadn't stopped, just kept on whaling on him? Dean's always had a temper - but after coming back from Hell? Eyowch!

My sincere thanks to dreamerswaking for suggesting a take-off on this ep. I'm always up for a new way to break Sam. Got a few more cooking. Hope this one works for you-all.

BETRAYAL

Sam jumped up from the table as Dean stomped into their motel room. Astonished, he watched as his older brother walked past him and started to stuff his clothes into his duffel bag.

"Dean, what are you doing?"

No response.

Sam tried again. "What, are you leaving?"

"You don't need me," Dean answered coldly, not looking up. "You and Ruby can go fight demons." He pushed past Sam, going for the door.

Sam grabbed his arm. "Hold on, Dean. Come on, man."

At Sam's touch, Dean spun around and punched his brother in the face.

Knowing Dean had every right to be angry, Sam said, feeling his mouth gingerly. "You satisfied?"

Dean hit him again.

Sam took it. "Guess not," he said wryly.

"You want to tell me what's going on with you and Ruby, besides the psychic bullshit?"

Oh, crap. "Dean, it's not -"

Dean grabbed him by the shirt and Sam's hazel eyes widened as a hard fist plowed into his mouth, splitting his lower lip and sending blood spilling down his chin.

Dean cursed and slapped him on the side of the head, making his ears ring. "You stupid shit!"

"Dean! Stop!"

"I went to hell for you!" Face twisted with rage, Dean punched Sam again. "Hell!"

He slapped Sam sharply across the face, again and again, pushing his brother's flailing hands aside when he tried to shield himself.

"Dean!" Sam gasped.

Dean slugged him again, knocking him to the floor. "You're fucking a demon!" He aimed a savage kick at Sam, catching him in the ribs and knocking him over onto his back.

"Dean!" Sam stared up with dazed, pain-filled eyes. "Please!"

"Please what, Sam?" Dean sneered, looming over him. "Forget that a demon killed our mother? Our father?" He pulled Sam roughly to his feet and shoved him roughly up against the wall.

"Forget forty years in Hell!" A fresh spurt of rage took him and Dean pulled his fist back and slammed it into Sam's jaw with all his strength, sending his brother's head thudding into the wall.

As Sam's body went limp, Dean let him go and he collapsed bonelessly onto the floor.

Dean glared down at him, his breathing harsh and uneven. "You betrayed me, Sam. You betrayed our family. You betrayed the fucking human race."

With a final kick to Sam's ribs, Dean turned his back on the last of his family and left the motel.

(((((((((())))))))))

Dean sat in the Impala, staring across the street at the motel.

It was just a little beat-down. He'll be fine.

He upended the already half-empty bottle of whiskey and took another healthy swallow.

Did he think there wouldn't be consequences?

Damned Alastair had told him that Sam was screwing a demon. Hell, he'd even shown him, but Dean had been sure it was a lie; sure that his brother would never betray him like that.

Tonight, realizing that what Alastair had shown him had been real - he'd freaking lost it. Maybe he'd given his brother a little more of a beating than he'd meant to.

Maybe.

On the other hand, Sam hadn't even fought back. He'd known that he was wrong, known that he deserved whatever Dean did to him.

Stupid kid.

Fucking Ruby.

Dean had seen the way she and Sam had looked at each other after Sam had exorcised the demon. That shared glance had spoken of intimacy as clearly as if he'd seen them screwing.

Using his demon-given powers, screwing that hell-bitch Ruby - lying to his brother - what else had Sam been up to?

Whatever. It stopped now. Big brother was back. Sam would fall in line.

As if summoned by his thoughts, Dean saw his brother stumble out of the motel.

Even knowing how he'd left him, it was still a shock to see Sam's bruised and bloody face.

"Shit."

Don't go all big brother - it's not like he didn't deserve it.

Sam tripped over the curb into the street and just barely managed to stop himself from falling.

Dean flinched. He steadied himself, stepped out of the Impala and stared at his brother impassively.

Sam heard the car door slam from across the street and squinted, vision blurring and tunneling. "Dean?"

"Sam."

"Did - did you come back to keep your promise to Dad?"

"What?" Dean's voice was sharp with surprise. "I - I won't stop you, Dean. Do what you have to."

Dean's mouth twisted bitterly. "Do you really think I'd kill you, Sam?"

Sam gave a little laugh, then choked, the sheen of blood on his lips. The screw in his head tightened another notch.

Dean saw that his teeth were red with blood and his eyes went wide with dismay.

"Think - you gave it - a good shot - brother," Sam said weakly. His eyes rolled back in his head and he fell.

As Dean stood frozen, a car came around the corner and skidded to a halt just short of Sam's crumpled body. The three occupants of the car piled out and bent anxiously over his brother's still body.

Unobserved, Dean slid back into the Impala, all too aware of the blood on his clothing and his scraped and bruised knuckles.

As he watched, a few people from the motel and surrounding businesses came out to join in the drama. Within a few minutes a police car and an ambulance were turning into the street and soon after that, Sam was whisked away, the ambulance's siren screaming and the police car following close behind.

Eyes vacant, Dean drained the last of the whiskey. He tossed the empty bottle into the back seat, started the car and went after his brother.

Smiling, Ruby stepped out of a nearby alley and looked after the Impala.

Couldn't have gone better if she'd planned it herself.

Humans. Gotta love 'em.

(((((((((())))))))))

This was hard to write. I don't like it when Dean hurts Sam. Dean's the one that supposed to fix him! (sigh)

Got no idea if it's good or complete crap but I'm outta here - can't spend another freaking minute in the Dean is Mean universe. I'm heading back to Brotherly Schmoop Universe. Or maybe Brothers Who Boff Universe.

Any further Sam breakage will not be done by Dean, 'cause that's just wrong!
