The House of the Dragon Season 3 finale delivers one of the most anticipated clashes of the Dance of the Dragons: the Battle of Tumbleton. But true to form, the show doesn't just replay the events of George R.R. Martin's Fire & Blood—it reshapes them. By giving the so-called "Two Betrayers"—Hugh Hammer and Ulf the White—more nuanced arcs, the series turns a straightforward betrayal into a deeply personal and tragic turn of events.
In the source material, Hugh and Ulf are essentially power-hungry opportunists who switch sides to the Greens and later declare themselves kings. The show, however, has spent two seasons building them up as sympathetic figures from humble beginnings. Season 2 introduced them as struggling smallfolk, and Season 3 deepens their motivations, making their choices feel less like villainy and more like desperation.
Ulf's Grudge Takes a Dark Turn
Ulf's path in the show mirrors his book counterpart in broad strokes—he does betray Rhaenyra—but the reasoning is far more personal. After Daemon publicly humiliates him in King's Landing, Ulf's wounded pride makes Ormund Hightower's offer of allegiance tempting. Yet Ormund proves just as cruel, beating Ulf when he finds him asleep during the battle. In a shocking twist, Ulf kills Ormund and becomes a wild card, no longer loyal to any side. This version of Ulf is not a calculating traitor but a man pushed to his breaking point.
Hugh's Heartbreaking Choice
Hugh's storyline takes an even more emotional route. His love for his wife, Kat, has been a central thread since Season 2. In the finale, he abandons his post to protect her during the battle, but arrives too late. The tragedy of her death leaves him shattered—and likely sets him on a collision course with Rhaenyra in Season 4. Unlike his book counterpart, who simply seeks power, this Hugh is driven by grief and a sense of betrayal by the queen who sent him to war.
These changes don't just make the characters more compelling; they also align with the show's broader theme of elevating the smallfolk. By giving Hugh and Ulf agency and depth, House of the Dragon ensures that even the non-Targaryen players matter. As the series hurtles toward its endgame, the fallout from Tumbleton promises to be as much about personal vendettas as about dragonfire.
