At this point, the more shocking revelation from the house of George R.R. Martin (sigil: dead people everywhere) would be if this wasn’t the case but a persistent and well reasoned ASOIAF fan theory – the persistent and well reasoned fan theory of the entire A Song Of Ice And Fire book series, and by extension, a fringe HBO TV show about dragons and sideboobs – is that Jon Snow is not in fact the bastard son of Eddard Stark (who, let’s be real, would sooner behead his own penis than use it to penetrate someone other than Catelyn Stark) but the royal offspring of Lyanna Stark, Ned’s sister, and Rhaegar Targaryen, Daenerys’ older brother, suspected paramours, deceased and mythically beautiful both, whose very union and the potential knowing nothing product of its consummation is likely referenced in the fucking title of the series (Starks = ice, Targaryens = fire).
Nothing that hasn’t been discussed ad nauseam before but it’s always nice to have things explained through the glorious medium of Powerpoint.
