I thought if I left it for a while that it would sort itself into something more linear and articulate. But what I'm doing is just remembering single episodes at a time, and feeling Sam's panic and Dean's countdown.
It was a tough season. There were some amazingly good eps, and some powerful scenes.
If I start listing them, I'll just do most of the season. So here, a list of memorable moments:
Dean and Casey, having a companionable chat about his motivations, and hers.
Dean and Lisa, and Ben, and one of the creepiest MOWs ever.
Sam giving Dean Christmas, and the pullout shot through the window, with the Christmas lights reflecting off the hood, including the Impala in the Christmas family portrait.
Sam, bored at watching Dean die. And then pursuing the Trickster with a frightening, deadly singleness of purpose.
Henrikson, in on the secret at last. "I shot the sheriff."
Dean, "But you didn't shoot the deputy."
Sam, arguably the finest bitchface in the series entire run.
Ghostfacers.
Car 54, Where Are You?
Bobby holi-fying the lawn sprinklers.
And this iconic BTS shot of Jensen preparing for Dean's death scene.

There were countless more I could mention, but these make the list tonight.
