The betrayal of Hugh Hammer and Ulf White is one of the defining moments of the Dance of the the Dragons. In George R.R. Martin’s Fire & Blood, the two Targaryen bastards become dragonriders in Rhaenyra’s service only to later abandon her cause and join the Greens during the First Battle of Tumbleton.

But House of the Dragon appears to be building two very different paths for its future traitors. While Hugh Hammer’s motivations remain a mystery, the series has already made it clear from its earliest episodes why Ulf White could never remain loyal to Rhaenyra for long. His problem was never a lack of opportunity. It was a lack of power.

How does Ulf White betray Rhaenyra?

In Fire & Blood, Ulf White claims Silverwing, the former dragon of Queen Alysanne Targaryen, during Rhaenyra’s call for dragonseeds. Alongside Hugh Hammer and Vermithor, he becomes one of the Blacks’ most powerful military assets.

However, during the First Battle of Tumbleton, Ulf and Hugh change sides and join the Greens, delivering one of the most devastating defeats of the war to Rhaenyra’s faction. Their betrayal destroys Rhaenyra’s trust in her own supporters and permanently alters the course of the Dance of the Dragons.

In the book, this decision can appear to be the result of sudden ambition. The series, however, seems to be suggesting something far more interesting: that Ulf never intended to remain subordinate once he possessed a dragon.

How does Ulf White die?

Ironically, Ulf White does not die in battle.

After the capture of Tumbleton, he becomes increasingly arrogant, unpredictable, and demanding. Ulf begins to demand castles, wealth, and honors that are incompatible not only with his origins but also with the trust his new allies have placed in him.

His behavior ultimately turns him into a political threat to both sides of the conflict. Fearing the power that Silverwing has granted him and recognizing that he can no longer be controlled, conspirators decide to poison him during a feast. Ulf dies not as a warrior, but as a man who had become too powerful to tolerate.

Has House of the Dragon already revealed why Ulf will betray Rhaenyra?

Probably.

From his very first appearance, Ulf displays a characteristic that fundamentally distinguishes him from Hugh Hammer: he does not accept hierarchy.

The series makes it clear that Ulf grew up suffering precisely because of his Targaryen ancestry. He carries resentment, feels cheated by life, and believes the world owes him compensation for everything he was denied. Unlike characters who seek honor or symbolic recognition, Ulf wants something far more tangible: money, castles, comfort, and, above all, respect.

Claiming Silverwing does not transform Ulf. It confirms everything he already believed about himself.

Ulf White has more in common with Bronn than many fans realize

In many ways, Ulf resembles Bronn, one of the most popular characters in Game of Thrones. Both men are opportunistic, pragmatic, and largely uninterested in honor, ideology, or permanent loyalty. Both believe that wealth and power matter more than political allegiance.

The difference is that Bronn never pretended to be anything else. From his very first appearance, he made it clear that he fought for money and survival. He also developed genuine bonds with Tyrion and Jaime Lannister, which ultimately earned him the audience’s affection.

Even when he attacked Daenerys Targaryen and Drogon during the Battle of the Goldroad, Bronn was still perceived as an imperfect but trustworthy ally.

Ulf is more unsettling precisely because he believes his ambition is a form of justice. He does not simply want wealth. He believes he deserves wealth. After a lifetime of suffering because of his Targaryen blood, he appears convinced that the world owes him riches, power, and recognition.

And unlike Bronn, Ulf acquires something that fundamentally changes his relationship with everyone around him: a dragon.

Bronn always understood that he depended on more powerful people to survive. Ulf, after claiming Silverwing, no longer depends on anyone.

He is no longer a survivor.

He becomes a military power.

Perhaps that is the true tragedy of Ulf White’s story. House of the Dragon does not appear to be telling the story of a man corrupted by power. Instead, it seems to be telling the story of a man who always believed he deserved power — and who finally found proof that he was right.

If the adaptation remains faithful to Fire & Blood, Ulf White will still be remembered as a traitor. But HBO appears to be suggesting something far more uncomfortable: perhaps Rhaenyra was not betrayed by an unpredictable man.
