In my post about Supernatural 9.12, I already discussed Sam’s issues and Dean’s issues and how they both do things that feed into the mess the brother relationship has become. So I won’t retread that. After 9.13, “The Purge,” all that is still in play and non-resolved, but Supernatural has taken another step towards repairing the brother bond, and moving it towards something less damaging.
Many factors go into the making of a TV show, from executive producers to writers, from actors to set designers. Details small and large come together to tell the story that winds up on our screens, and fans are also sharp-eyed, they’ll notice if something is off, and also respond to the beauty of a set or a sharp turn of phrase or how the lighting reflects the characters’ emotional states, Likewise with the ingredients of the story, and while all shows have lead, or main characters, they are not the only ones who move the plot–or who move the audience to tears.
