(This article will contain spoilers for Game of Thrones, A Song of Ice and Fire, and George RR Martin’s supplemental material. It will also cover potential plot points that could very well turn up in the future of the series. You’ve been warned!)
Last week on Game of Thrones, we were teased by the “Tower of Joy” sequence and unceremoniously yanked out of Bran’s vision before we could enter the tower with Ned Stark. For casual viewers, this was just a cool fight scene with a hint of mystery, but to those who have been reading and theorizing about A Song of Ice and Fire for years, it was a somewhat irritating stalling tactic for a reveal that we’ve been expecting for a long time. The R+L=J theory is so well-known and well-supported at this point that it’s essentially canon, so holding out of the reveal feels less like suspense and more like prolonging the inevitable.
But there’s another theory that is less widely accepted by fandom and, I feel, almost as likely to be true as R+L=J. If you’re paying close attention to the supplemental material and the scenes included in the TV adaptation, there’s a strong reason to believe that Tyrion Lannister is, himself, half-Targaryen.
