Maybe we should just all agree that Sansa is truly the Big Bad of ASOIAF and is responsible for every bad thing that ever happened in the entire history of that universe because she is, in fact, He of Many Faces or whatever, reborn as a mortal girl, and is secretly manipulating all the events of the books - and the only thing that can ever undo her/his work is a child born of a Stark and a Lannister and since He of Many Faces is, in this mortal form, a Stark, that means sex with Tyrion is bad.
Also, this is why Sansa and the Hound form a bond. Because He of Many Faces is in fact: HADES! LORD OF THE UNDERWORLD! WHO, SICK OF BEING STUCK THERE AND HAVING TO SUBJUGATE HIMSELF TO ZEUS, FOUND THIS OTHER WORLD AND DECIDED TO BE A DEITY FOR IT INSTEAD. AND SANDOR IS ACTUALLY CERBERUS, TRAPPED IN A MORTAL FORM AND WITH NO MEMORY OF WHO HE/IT REALLY IS.
…I’m reallyyyyyy tired okay?
and I might have had some honey whiskey.
