re: GoT Season 7 Casting News, Speculation, Spoilers, etc.

I don't see what either of them gain by a "dutiful political" marriage between Jon and Sansa. As far as the North is concerned, they are brother and sister. Jon's power at the moment rests largely with the assumption that he is Ned's son and true-ish heir. And the North would not accept a brother/sister marriage as legitimate.

Some posters are getting ahead of themselves with the "cousin" thing; only the viewers know the truth. Old Howlin' Reed might know, but we have no reason to think he's a factor at this point.

The whole Jon + Sansa thing is a weird fantasy invented by the kind of people who write erotic fan fiction.
