Watching How to Win Friends and Influence Monsters it struck me that the only way Supernatural could ever end satisfactorily is for the Winchesters to go out in a blaze of glory.
It has been demonstrated time and again throughout the series that hunters don't retire, but there has always been this underlying, optimistic suggestion that somehow Sam and Dean would beat the odds and have a happy ending.
The year, the arrival of the Leviathans has very rapidly eroded that hope. It's rather a perverse thing to say but I think true and final deaths for our protagonists can be the only satisfactory ending for the show - how many times can they dodge the bullet, escape hell etc?
How to Win Friends and Influence Monsters begins as a straight-forward, old school hunt for the "Jersey Devil", a monster believed to be eating campers in New Jersey, but Bobby and the brothers Winchester find out there's nothing straight-forward about this hunt at all.
Something has been drugging the triple meat sandwiches at the local branch of Biggerson's, turning customers into either placid stoners or rampaging cannibals.
Tracking the meat back to its source, our heroes discover that the Leviathans are responsible - although the whys and wherefores remain unknown to them (we. the viewers, are allowed more insight into the Leviarthans' operations than the Winchesters).
A plot involving mystery meats immediately made me think of the Buffy episode Doublemeat Palace, but where that went off in its own unique Buffy direction so this episode evolves in a way only a Supernatural story could.
We also get to find out more about the Leviathans' leader Dick Roman (James Patrick Stuart), allowing regular writer Ben Edlund the opportunity to squeeze in as many "dick" jokes as he can into a serious news montage.
