“I wanna make sure you understand. You won’t die or age. If this last year was painful for you, picture a hundred, a thousand more like it.”
In a show about absent and neglectful fathers, Jimmy Novak agreed to an eternity of pain to save his daughter. Seconds away from peace in Heaven, he begged through the blood in his teeth for Castiel to cage him away in his own skin, forever, so that Claire could be spared. So many people think that Cas learned about love from Dean. I think maybe he learned it first from Jimmy Novak.
