Only two episodes of A Knight of the Seven Kingdoms have aired so far on HBO in the 2026 TV schedule, but the newest Game of Thrones spinoff didn’t even need more than the first five minutes to prove how different it is from House of the Dragon. One show is almost entirely populated by Targaryens and their relatives; Targaryens are few and far between on the other. Several generations have passed between the timeline of House of the Dragon, so the series really could be taken pretty separately.
That said, there’s one element of Knight of the Seven Kingdoms that I believe vindicates Rhaenyra in the TV version of Westeros. It feels more accurate to George R.R. Martin’s Fire & Blood than the show actually based on that fictional history book. For that, though, we do have to start out with a branch of the Targaryen family tree that has barely been explored just yet.
