Fortunately, Secretly Evil Sammy returns at this moment from wherever the hell he'd been to brightly announce, "There's been another one -- a dentist drilled a guy to death!" Dean thinks that one over for a bit, then guesses, "You mean the non-sexy kind of drilling, right?" "Fifty bucks says he's mixed up in all the crazy," Secretly Evil Sammy wagers by way of response, and he goes on to propose they immediately embark to quiz the good doctor on his state of mind and whatnot. Deeply Disturbed El Deano, still tiresomely wary of the thing his brother might or might not be at the moment, begs off, claiming he'd be far more interested in some good old-fashioned research at the moment, so Secretly Evil Sammy shrugs his remarkably healthy shoulders around and leaves to interrogate Doctor Paul on his own.

One problem: Doctor Paul hanged himself in his holding cell before Secretly Evil Sammy had a chance to talk to him, as we learn when Secretly Evil Sammy himself phones Deeply Disturbed El Deano with the news. Fortunately, Secretly Evil Sammy's managed to have a nice, long chat with the perky hygienist, so he knows all about No-Name Pervert and the foul depredations to which he was confessing shortly before he was so justly murdered. "So," Dean supposes, "Root Canal and Russian Roulette -- both of them, it was like they were cursed? People just compelled to puke the truth all over them?" Secretly Evil Sammy mugs that Dean might be on to something with that little notion of his, then orders his brother over to Doctor Paul's former offices to see what he can see while Secretly Evil Sammy heads to the morgue to examine the corpses. Dean has little choice but to agree and, after he shuts his laptop on the Doppelgänger research he'd been clandestinely conducting, he dutifully heads over to...

...the dentist's office, which is still positively livid with blood and guts. "GOOOOOOOOOOOOORE!" Dean sneaks past the police tape now blocking the crime scene, tippy-toes through the ruined examining room, and eventually creeps into Doctor Paul's consulting study, which features a prominently displayed saxophone, several photographs of Abused Melissa tooting on a trumpet, a tin case of reeds on the desk, and a receipt from Harry's House Of Horns. Dean flashes back to Pathetic Jane's pathetic cat calendar, on which were noted several regularly scheduled appointments at Harry's House Of Horns and beside which was a label from the same establishment. Thinking fast, he pockets the receipt, swipes a photograph of Deceased Doctor Paul, and heads on over to...
