House of the Dragon Season 3 premiere reshapes characters and battles
The Season 3 premiere of HBO’s House of the Dragon opened with the Battle of the Gullet, a massive naval clash between the Blacks and the Greens. In a notable deviation from George R. R. Martin’s Fire & Blood, the series shows Daemon Targaryen’s daughter Rhaena claiming the dragon Sheepstealer. Her inexperience leads to friendly fire that kills her step‑sibling Jace and his dragon Vermax, a death that in the novel is caused by the character Nettles.
The episode also introduces “Roddy the Ruin,” portrayed by Tommy Flanagan, who arrives with northern troops bearing Stark banners. He tosses the severed head of Lord Jason Lannister at Daemon and declares, “We have come to die for the dragon queen!” This character, based on Lord Roderick Dustin of Barrowtown from the books, adds a new faction of northern soldiers to the ongoing Targaryen conflict.
