House of the Dragon Season 3 Ending Explained

Note: This story contains spoilers from “House of the Dragon” Season 3, Episode 8.

“House of the Dragon” Season 3 ended the only way it knew how — with battles, betrayals and death.

The third season of the HBO drama series was bookended by massive clashes as the armies of Team Black and Team Green squared off and the Dance of the Dragons reached its peak. The finale saw the constant scheming of Ormund in the small town of Tumbleton finally bear fruit as Daemon, Roddy the Ruin, and a huge host of Rhaenyra’s armies appeared to snuff out the threat of the newly-knighted Daeron the Daring for good.

Elsewhere, Rhaenyra’s paranoia continued to spiral with news that her brother Aegon was spotted alive — and with his own returned dragon Sunfyre to boot. That fear caused her to put some drastic measures into motion to ensure she remained on the Iron Throne — despite it clearly rejecting her.

Here is how “House of the Dragon” Season 3 ended and what those big character beats mean for the upcoming final season.

Rhaenyra’s shocking reveal

When news arrives to Rhaenyra that Aegon not only still lives but so does Sunfyre and they’re burning battalions in the Riverlands, she is quick to want to be officially crowned as queen in front of the eyes of the Seven and the people of King’s Landing.

Despite wanting to be officially anointed queen, Rhaenyra dresses for battle and heads to the sept. Inside, not only is she chastised for bringing weapons into the holy place, but those inside seem convinced that the news that Aegon has been “resurrected” is all the proof needed that he’s the rightful heir.

She doesn’t accept the logic and falls to Plan B. Citizens had gathered outside the sept and Rhaenyra heads out and explains her true claim to the throne — her knowledge of the prophecy. Years earlier, after announcing Rhaenyra to be his heir, Viserys confided in his daughter a secret that only Westeros’ rulers knew — a prophecy passed from Aegon the Conqueror called “A Song of Ice and Fire” that told of a coming darkness that would take the entire kingdom united to defeat. This prophecy is what plays out in “Game of Thrones.”

Rhaenyra spins this tale on the entirety of Westeros needing to be unified but — as has been the theme all season — that her dragon might and numbers are the only way to survive. Then she shocks both those in attendance and readers of George R.R. Martin’s books when she claims herself as The Prince That Was Promised, a mythical hero said to be a savior for the world.

“It’s something that is certainly not in the book, and it’s not in the history, but there is a bunch of talk about how Rhaenyra became very despotic and became a tyrant at the end and was very unpopular with the people,” Ryan Condal said during a press conference about the finale. “So we saw it as this could just be something that happened, and there was disagreement over exactly what it was, so it didn’t make the historical record.”

He added: “We wanted something that felt like a real seismic change, a sea change in Rhaenyra’s relationship to her people. She’s seen the death of their religious leaders. She’s standing outside of the church of the faith of most of the people standing there as a member of a totally different faith — this old Valyrian faith of dragons and fire gods and blood magic, and pronouncing herself this chosen one and leader that is going to take them through the fire and out of out of the darkness.”

In “Game of Thrones,” Melisandre talked often about finding the Prince. Stannis Baratheon thought for most of his time in the story that he might be the Prince, but book fans maintained convinced that Jon Snow was the true claimant to the title. That did not prove to be true in the HBO adaptation but who knows what George planned for the books.

Either way, Rhaenyra is calling herself the fabled savior now.

The Battle of Tumbleton

The entire season had been leading to the Battle of Tumbleton. In the books, the poor city is the site of two different battles but the show condenses them both into one bloody affair.

Daemon arrives to lead the battle along with Roddy the Ruin and his Winter Wolves soldiers. They have a pretty standard plan — use Caraxes to blow the main gate and send Roddy and his Northmen through to take out Ormund’s forces. Unfortunately, Ormund planned for that and lined the weakest parts of Tumbleton’s fortifications with children. If Daemon wants to fight with his dragon, he’ll have to roast some kids. Instead, the plan is changed, Roddy goes over the walls with his men and get the doors open from the inside.

Roddy and his men scale the walls and the battle commences, and it’s as bloody as expected. But despite pushing deep into the city, Roddy does not get to the gates quick enough for Daemon, who grows impatient enough to summon Caraxes anyway. He manages to blow open the gates with dragonfire with only minimal child casualties (a win’s a win for the Rogue Prince) and now Team Black’s forces pour in from two fronts. Surely the city is all but lost. Surely.

The Great Betrayal

At the end of Season 3’s penultimate episode, Ulf seemed like he was ready to switch sides. Daemon and Rhaenyra had not given him the respect he thought he deserved and him working as one of the queen’s dragonseeds really cut into his free time to drink with the boys. Ormund made a pitch and Ulf seemed to take it.

Unfortunately, Ulf is not the most punctual guy. Ormund spends have the battle running through the city trying to find his recruited dragonrider but he is nowhere to be found. Eventually, he decides to finally do something about his promises. He goes to his dragon and quickly turns them on Daemon’s forces. Out in the open, they’re no match for the dragonfire.

But Ulf seems to be sick of nobility in general. Atop the battlements, Ormund and Roddy the Ruin are fighting. Ormund manages to hack up Roddy and cut off one of his arms, but a few well-placed shield bashes knock out most of Ormund’s teeth. Roddy throws him (still one-handed) against a wall and jams his knife where the sun doesn’t shine. And to cap off Ormund’s very bad day, Ulf turns away from scorching Daemon’s soldiers and aims straight for Tumbleton, somehow seeing Ormund. He lets his dragon loose on the city, first burning Ormund and Roddy to a crisp and then continuing on through the city. The aftermath leaves Daeron’s fate uncertain, in a potential departure from his fate in the books.

In the books, both Ulf and Hugh agree to betray Rhaenyra together but here Hugh remained loyal … to a point. He ignored his orders to stay at King’s Landing and also joined the battle, but on foot to try finding his family. He finds them after the battle and Ulf’s betrayal dead in his home. Hugh might not have betrayed for the Battle of Tumbleton but it’s hard to think he’ll be still Team Black for Season 4.

Helaena’s final word

Book fans knew it was coming. For the entire season, Helaena has been held prisoner by Rhaenyra and the threat of her pregnancy producing Aegon’s heir that could challenge her succession meant that her life was constantly in danger. Despite all that, she refused her mother’s protestations to get rid of the child.

The penultimate episode saw Helaena cycling through a number of prophetic dreams. Her watching the snows (or ash?) come to King’s Landing much like Daenerys brought at the end of “Game of Thrones,” her atop her dragon Dreamfyre burning the city’s people as they charged the dragonpit. These were all concerns to her and seemed to show only ruin awaited her and her family.

“You think that living is not dying,” she tells Rhaenyra in the finale. Explaining that just because Helaena was drawing breath didn’t really mean much if she was going to be kept as a piece on the board to be used to threaten the now-returned Aegon.

The final moments of the season show Helaena finishing the stitching and patternwork she’d been working on all season. She rises and heads toward the window and the moment cuts to someone running to get the queen. She heads to Helaena’s room to find that her half-sister threw herself from the window and impaled herself on the spikes below (shades of Tommen killing himself in “Game of Thrones”).

But even though Helaena chose her own way out, she had one last message for the queen. The embroidery she’d finished lay on the chair beside the open window. It had a number of prophecies to come stitched in — the main one is that Rhaenyra is doomed to die in fire.

“House of the Dragon” Seasons 1-3 are now streaming on HBO Max.
