Warning: Dragon-sized spoilers follow for the "House of the Dragon" Season 3 finale. There may be no such thing as happy endings in the world of Westeros, but some fates are worse than others in "House of the Dragon." For others, however, we knew the writing was on the wall — and Episode 8 saves its most heartbreaking death for last. While the finale does go out of its way to provide a fair amount of reasoning behind this drastic act, Helaena's death unfortunately proves Martin's point nonetheless. What we're left with is an unbelievable downer of an ending and the nagging sense that we're left with yet another missed opportunity in "House of the Dragon."
