Dean walks through the first door he comes to, while Sam follows him, clenching and stalling. Dean hears some air whistling and surmises that there is a door behind one of the walls. Meanwhile, Sam is starting to get a little sweaty; he grasps his shotgun, and whispers urgently, "Dean." Dean looks back to see Sam, with a bloody nose, aiming his gun at him. Dean tells him to put the gun down, and Sam starts to go a little psychotically younger brother: "Is that an order? 'Cause I'm getting pretty tired of taking your orders." Dean says, "I knew it. Ellicott did something to you." No, no, you didn't know it, Dean. Otherwise you wouldn't have blabbed your whole plan to an obviously shifty and possessed person. Sam tells Dean to "For once in your life, just shut your mouth." Ouch. Dean challenges him, "What are you gonna do, Sam? The gun's filled with rock salt. It's not gonna kill me --" when POW! he gets shot back through the hidden doorway. Cut back to crazy bloody Sam who says, "Nah. But it'll hurt like hell."Commercials. Dean lies on the ground coughing and aching and trying to tell Sam that if they burn Ellicott's bones "everything'll be back to normal." Sam stands over him, all au contraire mon frere: "I am normal. I'm just telling the truth for the first time. I mean, why are we even here? 'Cause you're following Dad's orders like a good little soldier? 'Cause you always do what he says without question? Are you that desperate for his approval?" He continues, telling Dean that the difference between them is that, unlike Dean, he has a mind of his own; that he isn't pathetic like Dean. This is pretty sinister. Sam continues to point the rock salt shotgun at Dean when Dean pulls a handgun out of his jacket, saying, "Well here, I'll make it easy for ya. Come on, take it. Real bullets are gonna work a hell of a lot better than rock salt." Sam barely hesitates before taking the gun and throwing the shotgun aside. He leans in real close, aiming the gun at Dean's head, and Dean asks the question of the hour: "You hate me that much? You think you could kill your own brother?" Sam's bloody face twitches as we cut between it, his hand holding the gun, and Dean lying on the floor. But we don't have to wait too long before Sam pulls the trigger, not once, not twice, not three times, but four freaking times! To no avail. The gun has no bullets. And here I am reminded of the immortal words of John McClane of Die Hard fame: "Oops, no bullets! You think I'm fucking stupid, Hans?" Dean takes the opportunity of having Sam leaning over and off balance to jump up and tackle him. He tells him, "Man, I'm not gonna give you a loaded pistol," before punching his brother's lights out.
