Back in the main office, shooting is apparently no longer an option, so Sam and Dean lash at the assembled dark demonic horde with holy water. As this is a tremendously ineffectual way of fighting the beasts, the boys end up cornered, and it's at this point that the sharply featured woman steps forward to slam Our Dear Numbskulls up against the brick walls with a little telekinetic mojo. And then? Dean screams, "Henriksen! NOW!" and Our Intrepid Federal Agent scampers into a supply closet to press Play on an old-fashioned cassette recorder. Instantly, Sam's voice, reciting the exorcism, floods through the station's public address system, and the dark demonic horde reaches for its ears as one to start with the screaming.
I love this show. So. MUCH.
Unfortunately, there's Yet Another Problem: Remember that luridly garroted deputy who punched a hole through Special Agent Reidy's chest? Yeah, he bursts through a door Nancy hadn't quite finished salting when the exorcism began. He menaces her briefly, but instead chooses to dart off into the night. Once the monster's gone, Amici rushes up from behind to finish what Nancy had started, and once all the exits have been secured, we duck back inside, where...
...the demons thrash about for a moment before throwing themselves at the doors in a mad and desperate panic (which is deeply disturbing in and of itself for the variety of unsettling parallels it brings to mind), but soon enough, heads snap back to unleash bitterly black geysers of demonic goo up at the ceiling, and as the freshly depossessed human hosts drop one by one, the roiling, roaring cloud on the ceiling grows ever larger until Tape Deck Sammy completes the Latination, at which point the entire swirling, swarming mess goes nuclear and explodes. The resulting flames quickly dissipate outwards towards the walls, and Our Intrepid Heroes, at long last, drop to the floor, panting and spent. "Dirty!" Oh, be quiet. You knew what I meant. "Hee!" They eventually pull themselves together, and Henriksen -- wiping some blood off his mouth -- joins them in the main office just as the fluorescents snap back on to illuminate the scores of freshly depossessed now awakening on the floor.
