...Mildly Amnesiac Sam tooling through the night in the wounded Impala with the barmaid at his side. "Play With Fire" is coming through on Metallicar's radio, just so you know, and Mildly Amnesiac Sam realizes to his surprise that he can smell whiskey, but the barmaid urges him to focus. "Who shot at us?" she demands. "I didn't really get a good look," Mildly Amnesiac Sam LIES. Good to know some things never change no matter where he is. Apropos of, oh, everything, the barmaid's growing increasingly agitated, and she orders Mildly Amnesiac Sam to turn the car around and head back to whatever nowhere burg they just came from. Mildly Amnesiac Sam argues that they'll both be safe, and as The Stones amp up on the radio, we shoot back to...
...the real world, where Dean flashes a penlight in Catatonic Sam's eyes.
Down in The Ginormotron's freakish Cro-Magnon skull, the sudden flash of light temporarily blinds Mildly Amnesiac Sam, and he stomps on the brakes to find that night has quite unexpectedly turned to day. He switches off the engine and hops out of the car to rage at the sky while the barmaid again attempts to bail, but Mildly Amnesiac Sam's ears prick up at the sound of forest noises emanating from the actual forest now surrounding them, so he orders her back in the car for her own safety. She warily complies, and he trots off to examine the contents of Metallicar's bottomless trunk, eventually selecting a sawed-off pump-action shotgun for himself, and with that, he tippy-toes off into the woods.
Tough-Guy Jazz-Hands abound as Mildly Amnesiac Sam makes his way through a clearing, entirely unaware of the fact that Assailant Sam's hiding behind a tree. "I'm confused!" Just keep sipping on your flagon, hon. "Okay! [Slurp!]" Eventually, Assailant Sam sneaks up behind Mildly Amnesiac Sam and quickly disarms him, and then he sets to speechifying. At length. For hours. And as I have no real desire to watch Jared Padalecki share the screen with himself at this point in this dreadful and dreadfully misbegotten season, I'll be cutting to the chase: Long story short, when Castiel ripped apart that wall Capital-D Death had erected to separate Sam's mind from his soul, or whatever, Sam's personality fragmented into three parts: Pre-Apocalypse Sam, whom we've been following since the beginning of this episode, Soulless Sammy, whom I've been referring to as "Assailant Sam" up to this point, and Lucifer's Cage Sam, whom we'll hopefully be meeting at some point prior to the turn of the next century. The Three Faces Of Sam must battle each other to the death deep within the mush that now represents Catatonic Sammy's brain, for as everyone knows, There Can Be Only One. Soulless Sammy naturally has a leg up on The Other Two Sams, because he's an amoral badass who has no qualms about shooting himself in the face. Unfortunately, Soulless Sammy is a lousy shot, for he proceeds to fire off four or five rounds in Pre-Apocalypse Sam's direction, and each and every one of them misses. D'OH! Pre-Apocalypse Sam tears off through the trees, eventually stopping long enough to realize he accidentally shoved Dashing El Deano's trusty pearl-handled automatic down the back of his pants back at the Impala. He stumbles across a cunning plan, and vanishes into the woods.
