Spoiler Alert

House of the Dragon might be a story about a Targaryen king and queen fighting over the Iron Throne, but its latest episode introduced a member of the family who is certainly not royalty. Or at least that man claimed to be dragon-born during “The Burning Mill.” A commoner named Ulf said he’s the bastard brother of King Viserys and Prince Daemon. Was the gregarious, well-liked bar patron telling the truth? Or was he telling a tall tale when he said he’s Rhaenyra’s unacknowledged uncle? Whether or not Ulf truly is who he claims doesn’t matter as much as whether or not he truly believes that he’s a Targaryen.

Ulf first appeared in episode two of House of the Dragon‘s second season wandering the streets near the Red Keep. There he asked about the ratcatchers hanging from the walls. But the next episode showed he’s much more than just a random denizen of the city. He visited a King’s Landing tavern/brothel, one he clearly frequents often, and began greeting many patrons excited by his arrival. Ulf was also there looking for a free drink. To get one, he regaled his table mates, one a complete stranger, with something he claimed he shouldn’t even be telling. It’s a story he brought up entirely on his own.

“It’s said even Dorne mourned the passing of my grandsire,” Ulf calmly told the Dornish man who ordered him a flagon. “They call him The Conciliator.” That was one of the many nicknames of King Jaehaerys, the longest ruling Targaryen king in Westeros’ history. House of the Dragon showed the beloved old King in its first episode at the Great Council. There Jaehaerys convened all the lords of the Realm to name his heir.

One of the many reasons Jaehaerys had no obvious successor was that the very father Ulf claims as his own died. “I’m the Son of Baelon the Brave,” Ulf said. Baelon was the second son of Jaehaerys. Until he died from appendicitis he was also briefly the king’s heir to the Iron Throne after the death of Baelon’s older brother.

Could the renowned, noble, heroic Baelon Targaryen have sired a bastard son named Ulf? Definitely. It’s not like otherwise good men haven’t committed adultery a million times in Westeros, including royalty. Baelon was also a young widower, so it’s possible he didn’t cheat on his wife at all, but instead sired a child out of wedlock either before he married or after his wife died. It’s also very possible Ulf’s mother simply lied about his father being a Targaryen entirely. Or she could have lied because his father was a totally different, less important Targaryen. (His unusual hair at least suggests some Targaryen blood.)

Why lie about Baelon if she slept with a different Targaryen? Maybe she told Ulf that Baelon Targaryen was his dad when he was heir to the Iron Throne.

If Ulf is telling the whole truth about his father, though, he really is an uncle to Rhaenyra, whom he called “the One True Queen.” Or at least he did until his supposed nephew Aegon showed up and a scared Ulf quickly yelled out, “All hail the King!”

Was anything Ulf said 100% true? At least thing one thing was. After claiming “the blood of the dragon runs through” his veins, Ulf said, “men would take my head” over it. He then called himself a “dragonseed,” a well-known term for Targaryen bastards usually used for kids born on the family’s ancestral home island. (There are countless dragonseeds there, though after a century King’s Landing definitely has its own fair share. We might have seen one of Aegon’s bastard kids in season one at the child fighting pit.)

Ulf also said a dragonseed “must watch his own neck when he has no white cloack guardsman to do it for him.” That’s not usually true, but it definitely is right now during a Targaryen civil war. Anyone foolish enough in King’s Landing to claim—to strangers no less—they are Prince Daemon’s brother is putting their life on the line. Even if he’s lying just saying that in jest for free wine and ale, it could be a death sentence.

So why do it? Free drinks are always nice, yet hardly worth the risk of losing one’s head. (They’re hanging ratcatchers for seemingly no reason down the street!) Being a little more popular with bar patrons isn’t worth that kind of danger, either. Plus, Ulf doesn’t seem brave enough to risk making such a bold claim, not even at an establishment where he’s well-liked. He’s not exactly brimming with courage.

Ulf’s obviously not that smart, but he’s obviously not completely stupid. He was smart enough not to speak too loudly. And he assessed the danger he was putting himself in correctly. Yet he still did it, as though he felt compelled to share his “secret” against his better judgement, just as he felt the need to openly support Rhaenyra (until he was frightened). All of this indicates he might actually believe what he said about his father.

House of the Dragon obviously included that scene for an important reason. Smallfolk don’t get that much characterization in the Seven Kingdoms unless they matter. Ulf—known as “the White” because of his hair in George R.R. Martin’s Fire & Blood—is obviously a character worth paying attention to even if you don’t know what awaits him in the future. But even if you do, all viewers should pay attention to whether or not he truly believes what he says.
