Jensen talked about his excitement about the introduction of Benny, the vampire Dean works alongside with to survive and escape from Purgatory, calling the character “a really great kind of contemporary for Dean. It’s a foxhole relationship. He’s been at war with this guy. On paper it’s not the kind of character that Dean would allow to live, much less team up with. Benny really earned his stripes with Dean.” And Sam will be aware of Benny
