House of the Dragon season 3 episode 8 spoiler review: "A Game of Thrones-worthy season finale"

House of the Dragon, for all its high-flying beasts, hasn't exactly soared when it comes to season finales. Season 2 was cut short by the 2023 Writers' strike, with the opening chapters of season 3 – climaxing in Rhaenyra's ascent to the Iron Throne – plainly the once-planned conclusion of season 2. One of the best things you can say about the House of the Dragon season 3 episode 8 is that it feels like a season finale, and a Game of Thrones-worthy season finale at that.

The centerpiece here is the Battle of Tumbleton, making this a season bookended by war on land and sea. Showrunner Ryan Condal compared the season's opening skirmish at the Gullet to Lord of the Rings' Helm's Deep, but the comparison is more appropriate here, not least because much of the battle involves the Winter Wolves scaling the walls of Tumbleton, but with far greater success than the Uruk-hai. Roddy the Ruin gets his glorious death, dying for his Queen in a blaze of dragonfire, but not before landing a cathartic fatal blow on season 3 rotter Ormund Hightower.

Truth be told, as entertaining as he's been this season, Roderick's slightly comedic path through the battle feels at odds with the severity of Tumbelton. Young boys meet brutal, bloody ends after Ormund forces them onto the front lines, Silverwing's dragonfire indiscriminately burns innocent civilians and soldiers, and it's clear from the literal fallout of the Battle – which evokes a nuclear apocalypse with its burnt orange haze – that dragon warfare benefits no one. Maybe Criston Cole was right to choose oblivion.

Under siege

Tumbleton is a triumph then, the kind of mega-scale battle that no show but House of the Dragon, and Game of Thrones before it, dare attempt on TV. The action choreography is superb; Roddy gets his own heroic oner that tracks him from the battlefield, up and over the wall. The dragonriding VFX don't always hold up to scrutiny, but what makes Tumbleton sing are the carefully earned character beats. Ulf getting drunk and missing the start of a battle that hinges almost entirely on his dragon is exactly what a character that self-centered would do with the guardrails taken off. When Gwayne makes a last-ditch effort to sue for peace with Daemon, you fear for the fan-favorite Hightower's safety, as much as you want Daemon to satisfy his bloodlust. And Ormund meeting his end because he put his faith in a traitorous dragonseed is a perfectly poetic comeuppance.

Rhaenyra doesn't make it to Tumbleton, but that's because she's fighting a war of a different kind on the home front – a war of legitimacy. The show wastes no time in letting Rhaenyra learn that not only is Aegon very much alive, but so is Sunfyre. Rhaenyra's no good, very bad day only gets worse from there, as she pushes away those close to her – Mysaria, Baela – and puts on a misguided show of force in the Starry Sept to force the Faith to anoint her.

Emma D'Arcy has long been the show's standout performer, and they are once again excellent here. Proselytizing in ill-fitting armor after having the High Septon executed, Rhaenyra's speech is one of the show's great monologues, as even though we know (almost) everything she says is true, her apocalyptic speechifying clearly comes across as the ravings of a mad queen to those watching on, something Mysaria will no doubt weaponize in revenge. It's just a shame that, three seasons in now, Rhaenyra has been kept off the front lines of the show's biggest sequences in a way that still makes her feel like she's in the backseat of history.

It's not easy being green

Speaking of backseat passengers, the misgivings I expressed in my House of the Dragon season 3 review, which covered the first four episodes, that Aemond was being underutilized, has proven true to the very end of season 3. The decision to trap Aemond in Harrenhal, after universal frustration over an identical misstep with Daemon in season 2, is a puzzling choice to say the least.

Finally learning the intriguing truth about Alys Rivers (if she's even telling the truth, that is) doesn't justify two seasons of not much at all happening at Harrenhal. Aegon's darkly comedic reunion with Aemond is electric, and superbly played by Tom Glynn-Carney in particular, but it needn't have come at the expense of Aemond being a non-entity for an entire season. Alicent, meanwhile, feels as much of an afterthought in the finale as she has all season.

Also bound to be controversial is Helaena's long-feared death. The adaptive choices around Helaena have been a sore spot for Game of Thrones creator George R.R. Martin, who singled out the decision to cut Helaena's son, Maelor, from season 2's blood and cheese as but one toxic butterfly that would have catastrophic consequences down the line. George may have overreacted a tad, as Helaena's tragic death here not only feels inevitable, but is a hugely upsetting and impactful moment, bolstered by Ramin Djawadi's heartbreaking score. It'll undoubtedly have huge ramifications going into season 4.

Season 3 has had some less-than-stellar episodes along the way but, overall, this has been a far more confident and undeniably complete season, one that has seen the power balance in the Dance of the Dragons shift completely over the course of eight episodes. Westeros-set shows aren't known for sticking the landing, and many will no doubt continue to bemoan the show's many divisive adaptive changes, but with the season 3 finale, House of the Dragon is heading into its fourth and final season from a position of strength.
