Does Ulf the White Really Betray Rhaenyra in ‘House of the Dragon’?

Fans following ‘House of the Dragon‘ have been asking one burning question as the Dance of the Dragons unfolds. Does Ulf the White actually turn his back on Rhaenyra, and if so, why does a man she personally elevated end up joining her enemies.

The short answer is yes, and the story behind his betrayal is far messier and more human than a simple villain turn. Ulf’s arc has become one of the most talked about threads of the ongoing Targaryen civil war, and it traces back to how he was recruited in the first place.

Ulf the White and the Dragonseeds Storyline

Ulf was introduced in ‘House of the Dragon’ season two as a man from King’s Landing with silver hair who claims to be the grandson of Jaehaerys I Targaryen. While Ulf is not Jaehaerys’ grandson and is not part of the direct line of succession, he does have Targaryen blood, and Hugh, also a poor man from King’s Landing, shares that same lineage.

Rhaenyra’s decision to recruit men like Ulf came out of desperation. Her forces were badly outnumbered on dragonback, so she opened the door to so called dragonseeds, men and women of possible Targaryen descent who might be able to claim a riderless dragon for her cause.

The four seeds who emerge successful and fight for Rhaenyra’s succession are Addam of Hull, Ulf the White, Hugh Hammer, and Nettles, with Addam claiming Seasmoke, Ulf claiming Silverwing, Hugh mounting Vermithor, and Nettles taming the wild dragon known as Sheepstealer. Silverwing had belonged to Queen Alysanne Targaryen, which meant Ulf was suddenly sitting on one of the most historically significant dragons in Westeros.

For a man who had spent his life as a nobody in King’s Landing, that kind of power changes everything. It is that shift, from powerless bystander to dragonrider, that many now point to as the real root of what comes next.

Why the Betrayal Actually Happens

According to reporting on the source material, Ulf’s problem was never a lack of opportunity, it was a lack of power, and the series appears to be building the case that he never intended to remain subordinate once he possessed a dragon. That reading reframes the betrayal as something less about sudden greed and more about a man who always believed he deserved more.

The turning point comes at the Battle of Tumbleton. Rhaenyra sends Ulf, Hugh, and their dragons to defend the outpost, but the dragonseeds immediately betray her forces, using their dragons to set the town ablaze and realigning their loyalties to Team Green, after which Ulf and Hugh become infamous as the Two Betrayers.

Part of what pushed them there was broken promises. Daemon tried to convince Rhaenyra to reward Ulf and Hugh with real power, including proposals to marry Ulf into House Stokesworth or even grant him control of Storm’s End, but Rhaenyra refused, sensing their ambition was rooted in personal advancement rather than the greater good. That refusal, fair or not, seems to have confirmed exactly what Ulf already believed about his place in her court.

The fallout hits Rhaenyra hard, as she grows increasingly paranoid that her remaining dragonseeds will also turn on her, and the betrayal causes turmoil for both Team Black and Team Green alike.

What Happens to Ulf After He Joins the Greens

Switching sides does not exactly buy Ulf the life he imagined. After Rhaenyra takes over King’s Landing with Hugh’s help, he is awarded a knighthood and lands on Driftmark, but once the pair defect at Tumbleton and join the Greens, Hugh starts calling himself Lord and believes he is destined to become king.

Ulf does not fare much better on the other side of the war. After the capture of Tumbleton, Ulf becomes increasingly arrogant, unpredictable, and demanding, pushing for castles, wealth, and honors that are incompatible with both his origins and the trust his new allies had placed in him, which turns him into a political threat to both sides of the conflict.

Team Green’s Prince Daeron does offer Ulf the title of Lord of Bitterbridge, but it is not enough to satisfy him. That kind of bottomless ambition ends up costing him everything.

How the Story of the Two Betrayers Ends

Neither man walks away from the war they helped decide. The Two Betrayers are killed in and after the Second Battle of Tumbleton, with Ser Jon Roxton putting a sword through Hugh before the battle even concludes.

Ulf’s ending is arguably even more pathetic given his ambitions. While the drunkard Ulf sleeps through the action and still tries to claim the throne, Ser Hobert Hightower gives him poisoned wine instead. He drinks three glasses and succumbs to the gentle poison in his sleep an hour later, a quiet and almost humiliating end for a man who once rode Queen Alysanne’s own dragon.

It is a bleak conclusion for a character whose arc started with real promise. Ulf went from an overlooked man-at-arms to a dragonrider who helped win the Battle of the Gullet, only to let ambition curdle into the very thing that destroyed him. Whether the show frames him as a tragic figure or simply a cautionary tale remains to be seen as season three approaches.

Now that Ulf’s fate and motivations are becoming clearer, do you think ‘House of the Dragon’ is setting him up as a genuine tragedy or just a warning about what happens when unchecked ambition meets a dragon.
