If you’re a Game of Thrones / ASOIAF fan, you may have already heard of the R+L=J fan theory. But, I promise you have never seen it presented in such exhaustive detail. I, for one, have always believed this theory to be true.
Warning: If this theory is true then it could be considered a plot spoiler for a future book or TV season.
Having come to this conclusion myself, I’m guessing this is almost certainly true.
And yes, this is sort of spoiler-y, though not really cause no one save George R. R. Martin knows for sure (well and maybe the show’s writers).
