Dean jumps all over this pause in the action to arm Nancy, Amici, and Henriksen with a few possession-blocking amulets he managed to pull from the Impala. "What about you and Sam?" Nancy wonders. The boys -- in unison -- pull aside their shirts to reveal a matching set of amulet-patterned tattoos inked onto their upper chests. Woof. "Smart," Henriksen approves, even though nobody asked for his damned opinion on the matter. "How long you had those?" the agent continues. "Not long enough," Sam glums, and CALLBACK! And now?
We wait for the assault proper to begin, of course. In the meantime, Henriksen gets to gaze mournfully upon Dead Sheriff Dodd's nameplate in said corpse's former office while Dean offers him a couple of sympathetic eyebrows. Out front, Nancy gasps when she spots about thirty of her possessed townsfolk gathered in the parking lot next to the bombed-out helicopter. Of note in the crowd is that luridly garroted deputy who punched a hole through Special Agent Reidy's chest. Sam sidles over to explain the whole possession sitch; Amici slinks through a back room and hoists himself up to wipe condensation off the window so he can peer out into the surrounding darkness. Unfortunately, he accidentally breaks the line of salt on the window's sill while doing so. DOY.
Meanwhile, Henriksen and Dean engage in a lengthy "OMG MY MIND IS BLOWN"/"I've known about this shit since I was six" conversation in the late sheriff's office, the only important part of which is this: Dean, ever the optimist, is firmly convinced the world will end in blood and angst, but he intends to go down fighting nonetheless. Cheery! Oh, I suppose I should also note that he and Henriksen establish an amicable rapport during all of this as well, with Henriksen indicating he might like to join the Winchesters full-time to aid in the boys' neverending battle against Satan and all his variegated minions, but none of that matters, because Henriksen's going to be dead in about fifteen minutes. "Demian! Really!" Oh, hush up, Raoul. Like that's a frigging spoiler after this goddamned scene. They redeem an archenemy during the episode? That archenemy bites it by the end of the hour. It's, like, a law, or something. "I see your point! Do continue!" Thanks.
