Gordon got exactly what he deserved, especially after torturing Lenore and killing his sister. And hunting Sam. Hunted and killed by Sam, after being turned into a vampire and killing the closest thing he had to a friend in the world. No pity for that psychopath.
I found the pairing of Gordon and Kubrick interesting. Gordon is a cold atheist while Kubrick is driven by faith. It was a fitting end for Kubrick as well.
But of course it's the main storyline that makes this episode so good. It was gratifying to see Sam finally call Dean out. But on the other hand, it is so irritating/heartbreaking watching Dean hurt Sam like that. It leaves him so weak and vulnerable. Which is just what you know who wants.moreless
