The latest episode of House of the Dragon season 3 is a major paradigm shift for Westeros, as Rhaenyra Targaryen at last ascends to the Iron Throne.
But there's also one moment that might be a nod to one of the most controversial Game of Thrones moments of all – George R.R. Martin's infamous blog post taking aim at the butterfly effect caused by changes the HBO show made from his book Fire and Blood.
While the bulk of the post revolved around the decision to remove Helaena and Aegon's son Maelor from the Blood and Cheese incident (and, indeed, the entire show so far), Martin ended his post with these ominous words: "And there are larger and more toxic butterflies to come, if House of the Dragon goes ahead with some of the changes being contemplated for seasons 3 and 4…"
Now, in House of the Dragon season 3, episode 2, Helaena is in the garden reading a book about butterflies. Not just any butterflies, either, but butterflies from Naath, which carry a deadly illness that kills invaders (so, toxic butterflies).
The moment has naturally been spotted by fans and posted across social media:
you cannot convince me that helaena journaling about butterflies isn’t a nod to george’s beef with the show and the “butterfly effect” problem he had with helaena’s arc for season three. ryan condal is so petty and i kinda love it! pic.twitter.com/ta8djhP4DUJune 29, 2026

After the blog post, Martin was interviewed by The Hollywood Reporter, and he shared that his relationship with House of the Dragon showrunner Ryan Condal is "abysmal."
"Then we got into season 2, and he basically stopped listening to me," Martin told the publication. "I would give notes, and nothing would happen. Sometimes he would explain why he wasn't doing it. Other times, he would tell me, 'Oh, OK, yeah, I'll think about that.' It got worse and worse, and I began to get more and more annoyed. Finally, it got to a point where I was told by HBO that I should submit all my notes to them and they would give Ryan our combined notes."
