House of the Dragon season 3 episode 4 shows Rhaenyra Targaryen confronting immediate political and military challenges after ascending the throne.

The episode details the actions of Lord Ormund Hightower, who has stationed troops in the town of Tumbleton, creating a dilemma for Rhaenyra as she cannot attack without endangering local supporters.

Aemond Targaryen, riding the dragon Vhagar, is reported missing after a stabbing, and Criston Cole discovers that Alys Rivers remains at Harrenhal. Ormund threatens the displaced ruling lord and lady of Tumbleton, and his volatile behavior includes outbursts and a preference for cleanliness.

Ormund publicly forgives Kat’s brother Leo for defending her, then later abducts him and orders Prince Daeron to execute him, reflecting a pattern of cruelty similar to earlier series events.

In King's Landing, Rhaenyra appoints Ser Torrhen Manderly as Master of Coin and discusses appointments with Alyn, while also receiving requests for favors from Ulf, whom she detains in the Keep.

She orders a search for graffiti labeling her the "Queen of Bastards" and allows Gold Cloaks to respond aggressively, raising concerns about an own-goal that could alienate the populace.

Aegon and his schemer Larys travel to Rook's Rest, where Aegon believes his dragon Sunfyre may still be alive, while Larys works to keep him alive.

Daemon travels to the Vale to request funds from Lady Jeyne, during which his dragon Caraxes flies to a rocky ledge where he finds Rhaena, a half-demented rider bonded with the wild dragon Sheepstealer, who rejects assistance and departs.

Criston Cole expresses enthusiasm for Rhaenyra’s throne claim and announces a guerrilla campaign targeting the River Lords as they move south, pledging a pure and dragon‑free fight.

The episode ends with multiple characters facing personal and political pressures, leaving the outcome of their actions unresolved.
