Dean eyes a luscious girl at the bar intent on scoring. Sam huffs and reminds Dean they are on a case. Dean doesn’t listen to Sam and goes over to talk to the girl. Within minutes she’s on his arm and they’re heading for the door; Sam shakes his head in contempt, another notch on Dean’s belt.
Back at the motel room Dean and the girl get straight down to it. They kiss and head straight for the bed, hands all over each other. Dean opens his eyes to find himself chained to the wall, the room sinks away into darkness and he cries out into silence. Demon Alastair appears by Dean’s side and offers him a proposition “Join me and you just might actually survive down here”. Dean is about to tell the demon where he can stick it but he is cut off by the sound of his own screaming. An unseen force rips through his body like a knife, he can feel his insides burning as he struggles to get free. There is no end to his agony. Alastair asks him again. This time Dean has no choice but to say yes, and with that the chains fall from the wall and he is free. He looks the sinister demon square in the eye and says “What did you have in mind?”
“Hey, are you okay?” the girl asks. Dean is on the floor, he’d been crying out in pain.
“Y… Yeah, fine. Just a stomach ache, but I’m fine”. They get back down to it once Dean reassures her he’s fit to carry on and before they make it to the bed he finds himself in Hell again, this time he is the one doing the torturing. A faceless victim is on their knees in front of him begging for mercy and Alastair cheers Dean on as he hits the poor soul again and again; not showing any sign of relenting.
He hits his victim again and is brought back to reality when the girl falls to the floor clutching the cheek Dean just struck. Tears form in her eyes and she tries to scramble across the floor away from him, fearing he will strike her again. Dean, having realized what he has done goes over to her but she cries out in fear. She manages to get away from him and runs out of the door, but not before calling Dean a monster.
When Sam gets back to the motel room he finds his brother sitting alone in the darkness his head in his hands. “What, another one bites the dust?” he jokes. Sam sees Dean shaking on the bed and goes over to console him. “Dean. Dean? Hey, are you okay?” but Dean doesn't answer, just looks at his hands; a smear of the girl’s blood has painted his hand a scarlet red. He washes and washes but the stain won’t come off, almost like a permanent reminder of the pain he’s caused. Dean stares at his own reflection in the bathroom mirror. He used to see the dry shell of the man he was before his time in Hell and now, all he sees looking back are the eyes of a killer.
