"Cas? Oh, he's ... he's Cas, I don't know. I can't describe him. You have to meet him and then you'll get it." Castiel was beyond description, he was a baffling, fascinating, loyal, wise, idiotic weirdo. And lately,. since Dad ditched him and Sam went to college, he had weirdly become his best friend. "He gave me a jump on the highway. He teaches at the University of South Dakota and he likes bees a lot."

So yeah, basically super weird. Why he was here when he used to have a better gig, he had no idea but he wasn't complaining. "You'll meet him when we watch Die Hard."
