That evening, Dean wheels the rain-streaked Impala into an abandoned parking lot somewhere remote and disembarks to greet Sam, who's brought Mousy Isabel along for the processing summit that follows. "That the girl with the haunted kidney?" Dean asks, peering at her through the windshield of Sam's rental before marveling, "Just when you think you've seen it all." "Whaddya wanna do?" he asks, understanding that they "can't exactly burn the thing, 'cause she kinda needs it." "Well," Sam points out, "she can't just walk around with it." "The spirit's attached," he reminds us all, "and it's gonna use her to get close to anyone it wants revenge on." So, you know, he's implying that the ghost of Rose Brown won't be satisfied just slaughtering her final tormenters, but instead will likely go after everyone who ever slighted her at any point during her life. Interesting little conundrum they're facing here, isn't it? Shame about the sucky way they end up resolving it.

As they mull over their options -- which include black-market replacement kidneys and hoodoo -- Mousy Isabel emerges from the rental to wonder what gives, and it's at this point that Ghastly Rose makes the leap into Metallicar, assuming control of the Impala much like Constance Welch did way back during the pilot. Ghastly Rose guns the engine and takes off after Dean, who leads it in circles around the lot for a very long while until he somehow manages to get it to smash through the plate-glass window of a defunct gas station. Our Intrepid Heroes, of course, emerge from the entire ludicrous experience unscathed, but alas! A large, jagged shard of glass has magically embedded itself in Mousy Isabel's abdomen, and she promptly keels over, dead. How convenient. Ghastly Rose makes a brief appearance to apologize to everyone for being such a lousy Monster Of The Week, and then she self-immolates, leaving the boys alone to gasp and pant their respective ways into this evening's final CHOMP!-less commercial break.
