Helaena’s Decision Seals Rhaenyra’s Fate: House Of The Dragon Season 3 Finale Ending Explained

Warning! Spoilers for House of the Dragon season 3, episode 8, ahead!House of the Dragon season 3 comes to a close, and it's no surprise that it does so with fire, blood, and heartbreaking tragedy. This has easily been the most transitional installment of the Game of Thrones prequel series, beginning with Rhaenyra Targaryen taking the Iron Throne and carrying her through tumultuous weeks of her desperate rule. While the Black faction of the Targaryen family has hold of King's Landing, the Greens have continued to present a challenge. Ormund Hightower, in particular, has made things impossible.

Ormund's opposition to Rhaenyra comes to a head in the finale of House of the Dragon season 3 as the Battle of Tumbleton finally begins. It doesn't go how either side imagined, however, and in this version of the conflict, it's hard to say that anyone actually won. Daemon Targaryen showed restraint, using Caraxes only to burn down the gate, but the town of Tumbleton and many of its people burned regardless. Ormund Hightower died, but the devastation caused by Ulf White and Silverwing will reflect horribly on Queen Rhaenyra.

Even if the public ever recognizes after House of th Dragon season 3's finale that Ormund Hightower, not Rhaenyra, is responsible for Tumbleton, things won't look good for the queen. As the battle began, Rhaenyra presented herself to be anointed by the High Septon at the Sept of Baelor. When the man refused, Rhaenyra deemed him a traitor and had him immediately executed. It's certainly a dark omen, and one that is quickly followed by the deliverance of dark news. Upon Rhaenyra's return to the Red Keep, she discovered that Helaena had taken her own life.

Why Helaena Made That Choice In House Of The Dragon's Season 3 Finale

Helaena's death is something that those familiar with George R.R. Martin's Fire & Blood were expecting, but that doesn't make it any less tragic. This character is by far the most gentle and deserving of happiness in House of the Dragon, but as a daughter of King Viserys, that fate was never likely. Helaena was no stranger to tragedy, but she held on to hope and even purity while she and her daughter might have been allowed to leave King's Landing. Upon discovery that that could never happen, Helaena chose a different sort of escape.

Rhaenyra dismissed Mysaria in House of the Dragon season 3, episode 8, prompting the Mistress of Whisperers to warn Helaena of what was to come. She told the princess that Rhaenyra would never let her go, and that with Aegon and Sunfyre alive, Helaena's unborn child would remain a hostage. Ultimately, she comes to see that there is only one way to keep herself or her child from being used by Rhaenyra against her family. Helaena Targaryen threw herself from her tower window onto the spikes below.

Helaena's death is a huge blow against Rhaenyra. After all, there's a reason the queen wanted her younger sister fed and cared for. First and foremost, an heir would be extremely valuable to Aegon, so Rhaenyra having possession of that child provides her with a great deal of leverage. Additionally, Helaena is a dragonrider, so, while she refuses to fly, she adds strength to Rhaenyra's numbers. Then there are Helaena's dragon dreams, which Rhaenyra hoped could guide her forward. Now, Helaena can provide no such benefit.

Further fallout regarding Helaena's death will come from the people of King's Landing and the wider Westeros. Aegon's gentle wife was beloved by the people, and her death will not be well received. In Martin's Fire & Blood, rumors circulate that Rhaenyra had her sister killed, and this turns the people against their queen even more. Helaena's tragic fate, combined with the bloody conclusion at Tumbleton, will make a peaceful rule nearly impossible for Rhaenyra.

The Outcome Of The Battle Of Tumbleton Explained (& How It's Different From The Book)

There's no doubt that the Battle of Tumbleton was a disaster for both sides in House of the Dragon season 3's last episode. Ormund Hightower's men were heavily outnumbered, but he thought bringing Ulf White to his side would turn the tide of the upcoming battle. The idea was for Ulf to turn on the Black army and begin burning their forces instead. While he technically did this, it wasn't until long after the battle had started. Ormund's rage at finding Ulf drunk and unconscious on the toilet then inspired the dragonrider to burn the Greens as well.

Ulf essentially wiped out both armies and the town of Tumbleton all at once. If the Blacks' goal was to remove Ormund Hightower and Prince Daeron from power, they technically succeeded. However, countless innocent men, women, and children all died terrible, fiery deaths. Rhaenyra asked Daemon not to make her look like a monster to the realm, but Ulf threw that whole idea out the window.

This all plays out a bit differently in House of the Dragon than it did in Fire & Blood, though the overall outcome is the same. In the books, there are two Battles of Tumbleton that take place over a handful of days. In the first, the Greens won thanks to Ulf White and High Hammer's betrayal. In the second, Ulf misses the fighting because he passes out drunk in Tumbleton. This allows Rhaenyra's forces to claim victory. House of the Dragon has combined both these events into one, doubling the devastation.

What House Of The Dragon Season 3's Ending Means For Season 4

With Tumbleton and its people burned, the High Septon of the Faith slain, and Helaena Targaryen's body impaled on the spikes of the Red Keep, Rhaenyra will have a tough start in House of the Dragon season 4. The queen announced to the people in the season 3 finale that she is the Prince That Was Promised—the realm's savior against a threat to the North. In the face of immediate tragedy and cruelty, however, this isn't likely to mean much to anyone. Queen Rhaenyra Targaryen is officially a tyrant.

House of the Dragon season 3's finale has Aegon Targaryen ready to take back his throne. He and his newly recovered brother, Aemond Targaryen, are preparing to head for Tumbleton, where they intend to bring Ormund and Daeron under heel. When they find this burned town, they will have to decide on their next steps. Eventually, Aegon will head to King's Landing, while Aemond meets his own predestined fate at Harrenhal in battle against Prince Daemon.

Suffice it to say, House of the Dragon's fourth and final season will not be a happy one. This is a Game of Thrones series, so a joyous resolution was already unlikely. With Helaena gone and Rhaenyra submerged in tyranny, the people of King's Landing are sure to rise against their queen while welcoming back the usurper and his golden dragon. More fire, blood, and tragedy are on the way. For now, however, we can only mourn Helaena and the conclusion of House of the Dragon season 3.
