It's been a year since whatever the hell happened in last season's "Supernatural" finale, and when we catch up with Dashing El Deano, we learn he's spent the previous twelve months as quietly an unobtrusively as possible with Bendy Lisa and her son in Cicero. Of course, Dean's Indiana idyll quickly spirals down the crapper when The Ceiling Demon pops up from out of nowhere, his yellow eyes a-glint with merry malevolence, to make with the threats and the taunts and such until Darling Resurrected Sammy also pops up from out of nowhere with a nasty-looking syringe, which he promptly plunges through The Ceiling Demon's suddenly vaporous body and into Dean's chest. Whaaaaaaaaa?
Turns out Dean was actually infected with some sort of genie goo, and said goo filled his brain with a remarkably vivid Azazel hallucination. Had Darling Sammy not arrived with a needle full of genie goo antidote at that very moment, Dashing El Deano would likely have dropped dead. And just where did that genie goo come from, I hear you ask? Well, you remember that elaborately tattooed beastie from Season Two's "What Is And What Should Never Be"? He had three kids, and those kids are pissed that Our Intrepid Heroes offed their daddy. So pissed, in fact, that they waited more than four years to exact their revenge, but that's not important at the moment, because what is important at the moment is the fact that Sam's out of Hell.
Not that Sam has any clue how that happened, naturally. One minute, he was writhing about in agony down below with that bastard, Adam, and the next thing he knew, he was sprawled out topside all by his lonesome on the sere Stull Cemetery grass. Still, that's not as surprising as the other news Sam can't wait to spring on all of us: Their maternal grandfather, Samuel Campbell, was also resurrected shortly after Lucifer's abortive Armageddon, and he and Sam have spent the last year hunting creatures the likes of which neither have seen before with a passel of sullen-looking Campbell cousins who will likely be dead by the end of November sweeps. Well, you know. With a little luck.
In any event, the boys plus the Campbells quickly take out the frigging pissed-off genies, and when it's all done, Sam asks Dean to rejoin him on the road. Unfortunately, Dean's developed a deep sense of responsibility for Bendy Lisa and Bendy Lisa's brat, so he declines, and we have to wait at least another week to see the Impala out on the open road again. Under normal circumstances, we're sure we'd whine about that fact, but after sitting through this borefest, all we really want to do is take a nap.
