After 20 episodes, several bloody battles, and the death of two sons, Rhaenyra Targaryen (Emma D'Arcy) has finally done it. She's taken the Iron Throne of Westeros.The victory comes at the end of House of the Dragon Season 3, episode 2, which sees Rhaenyra and Daemon (Matt Smith) crash King's Landing on dragonback and take the Red Keep by storm. It's a massive development in both the show and its source material, George R.R. Martin's Targaryen history Fire and Blood. However, just like with episode 1's gargantuan Battle of the Gullet, House of the Dragon makes several changes when translating Rhaenyra's triumph to the screen.

From Alicent Hightower's (Olivia Cooke) new involvement to her father Otto's (Rhys Ifans) demise, here are all the biggest differences between House of the Dragon and Fire and Blood's takes on the Fall of King's Landing.Alicent is behind the Fall of King's Landing in House of the Dragon.

House of the Dragon's biggest change to the Fall of King's Landing has been in the works since the Season 2 finale, when Alicent came to Dragonstone to strike a deal with Rhaenyra. She told Rhaenyra that once Aemond (Ewan Mitchell) flew to Harrenhal, she would be free to take King's Landing, along with Aegon II's (Tom Glynn-Carney) head. Alicent would even tell the soldiers to stand down, and in return Rhaenyra would let her, Helaena (Phia Saban), and Jaehaera go free. This deal is all completely new to the show, and the same goes for the deal's execution in Season 3, episode 2, as Alicent keeps her word.In the book, the end result is the same: Alicent surrenders the city. However, she does so under duress. Rhaenyra offers her the choice between giving up her life and giving up King's Landing, and obviously, Alicent chooses to stay alive.
