So, Richard Roman’s had his primary underling drag that sniveling teenager from last week back to The Leviathans’ world headquarters in lovely downtown Mount Prospect, and after several very long minutes of intensely tedious speechifying and other foul examples of generalized wickedness, he eventually persuades the kid to translate The Metatron Stone for him. Even though Richard Roman could have just stolen the kid’s brain and all of said brain’s contents simply by latching onto the kid’s arm and morphing into him, but why take the easy way out now? I mean, it’s not like this is the second-to-last episode of the season or anything, right?
And while all that stupidity’s raging half a continent away, Darling Sammy deploys his mad Googling skillz back at Dead Rufus’s ridiculously scenic rustic cabin to learn what the audience figured out several episodes ago: Richard Roman now controls SucroCorp, and The Leviathans are thus poisoning the planet’s food supply through the additives SucroCorp manufactures. Our Intrepid Heroes would do something about this especially ominous development right away, I’m sure, were it not for the fact that they’re still missing a couple of ingredients for this year’s ultimate weapon, specifically the blood of both Crowley and The Vampire King. So, the boys first summon Crowley — who tells them to call him again next week during the finale when his presence will actually be needed — then hit the road to track The Vampire King down to the latter’s rather exquisitely-appointed lair on the outskirts of Missoula, Montana.
Needless to say, The Vampire King’s none too pleased to see them thanks to all of last season’s unpleasantness, but relations become a bit more amicable when Dashing El Deano saves The Vampire King from a dastardly last-minute assassination attempt initiated by Leviathan Edgar on orders from his boss. And in the end, The Vampire King willingly hands over a chalice of his own blood, so Sam and Dean need only secure Crowley’s participation and the bone of a righteous man before taking out The Leviathans for good. Simple, yes?
