Sometimes art, mostly Dragon Age

media literacy includes understanding why a media product was made, to whom it's being sold, and the assumed preferences of its marketing demographic. narrative is not produced or sold in a vacuum.

you might be totally correct that your ship would be narratively satisfying. I don't know, I'm not watching your show. Whether your ship is likely to happen on the show is a whole different question to whether it's satisfying, because the show is being sold to Netflix or Amazon or the BBC, and they are purchasing a show they think they can market to a particular demographic and that demographic isn't you, the nightmarishly online tumblr user. The show is being made for marketability to a constructed average viewer. It is being funded with that audience in mind. This art is being made to commission, and commissioned art is art, but at some point you have to stop expecting the Church to commission a statue of Lucifer fucking St Michael. It might be narratively satisfying, but that's just not what they're paying for.
