"That never happened in the books," Charlie grumps as they leave the building. "It's okay," Dean says. "We'll come back later when Doris Do-Right isn't here anymore." Charlie realizes this means breaking and entering. She remembers that this kind of thing hasn't gone so well for her in the past. Not that it went much better for those of us who had to watch it, mind you.
Somewhere along a long stretch of train tracks in the middle of the night, two teenaged boys are deeply engrossed in their handheld games when their evening stroll suddenly turns into a crummier version of Stand By Me. Boy 1 is the first to notice the dead man lying beside the track and points him out to Boy 2. Boy 1 picks up the nearest poking stick he can find, but his friend stays his hand. "Dude, that's a bad idea," Boy 2 says. "Your face is a bad idea," Boy 1 says. Well, you can't fault him for his keen debate tactics. Boy 1 taps the corpse right at the navel, eliciting a faint squelching sound. "See, nothing to worry about," Boy 1 says. He pokes harder and harder until the distended abdomen ruptures and splatters both boys in blood. They look down at their dripping clothes, then at each other and let out a "comical" scream in unison.
By the time Charlie and Dean get to the scene, the body has been cordoned off with police tape, beyond which a small group of gawkers has gathered. At Dean's insistence, Charlie makes their introductions to one of the cops on scene. "Save it," the cop says. "Your other agent's over there." Much to their surprise, they find that the corpse is up and walking around! Oh, wait. That's just Sam again. "What took you guys so long?" he asks. "What the hell are you doing here?" Dean asks. "Working the case, same as you," Sam says. Indeed, he's already gotten the dead man's info and determined there doesn't seem to be any link to the previous victim. Dean suggests he head on back to the Lair O' Letters, but Sam's insistent about staying. "Charlie, why don't you go talk to the witnesses?" Dean says, meaning he wants some Alone Time with Sam to argue. "But I don't want to miss the broment," Charlie protests. Dean says her name in just such a way as to let her know he wasn't really making a request. She gets the hint and skedaddles. "I know you're frustrated, but you're also sick," Dean says. "I'm not leaving, Dean," Sam says. Meanwhile, his molecules continue disintegrating into Cheeto dust.
