That was the greatest episode of television I've ever seen in my life.
Ben Edlund and Sera Gamble ILU.
CAS! WINGS!
"We could take out the scene where they sit on the Impala and talk about their feelings."
"Yeah right. You answer the hate mail."
WE'RE NOT EVEN BROTHERS HERE.
MY EPIC WINCEST LOVE CONTINUES.
LOOK HOW THEY GET ALONG.
MIIIIIIIISSSSHHHAAAA. THE ATTRACTIVE CRYING MAN.
I loved Kripke's death scene most of all. Oh Sera Gamble you're the greatest.
WHAT KIND OF DOUCHEBAG NAMES A CHARACTER AFTER HIMSELF?
Oh and also they continue to make a point of showing Sam's disapproval of Dean's drinking. I SWEAR IT'S GOING TO MATTER.
And Balthazar and Cas continue to have sexual tension.
...but not as much as Dean and Cas.
...AND NOT AS MUCH AS SAM AND DEAN.
Edited to add: Possibly not greater than "The End." Because nothing is.
