Warning: Dragon-sized spoilers follow for the "House of the Dragon" Season 3 finale. A mixed "House of the Dragon" season ended in an appropriately mixed way. The Season 3 finale delivered some stunning battle scenes that are different from what we've seen before in this universe, some funny Aegon II moments, and a phenomenal performance from Emma D'Arcy as Rhaenyra. That being said, the finale also delivered some bewildering adaptation choices that justify George R. R. Martin disowning the show and hint at great difficulties for the adaptation as it heads to its final season. Just in case you forgot who some of these characters are or why they matter, let's break down every major death in the "House of the Dragon" Season 3 finale.
