That there’s what we call character development.
Hey, I really enjoy your SPN metas. I was curious about your view on the W. brothers' childhood. Or, about one specific detail about it, anyways - I agree the rest is canon or implied through the characters' actions throughout the show. How do you know John was an alcoholic? I've seen many interpretations, but as far as I've heard he's never been seen drinking on the show. Is it your (and many others') headcanon or do you know something for real? Please tell :)
