While House of the Dragon has strayed a great deal from its source material, Fire & Blood, by George R. R. Martin, it has retained many significant plot threads of The Dance of the Dragons. The creators have exercised their artistic license in adapting the book to a television show, making changes for various reasons. This article explores the differences between the book and the show.

The first episode, titled "A Son for a Son", aired on June 16, 2024, on both HBO and Max. The episode received mixed reviews, with both praise and criticism. The adaptation streamlined the timelines to create a quicker narrative flow, which led to alterations in character relationships, and new ones were introduced, like the evolving relationship between Alicent Hightower and Ser Criston Cole.

1) Timelines

To keep the viewers engaged, at times, the creators decide to move over some plotlines too quickly. It is a shift that is needed but it also relegates a lot of the character relationships—like that between Rhaenyra Targaryen and Harwin Strong—to the background.

This may result in time jumps or viewers finding it difficult to truly understand how some of these relationships may have been integral to the character's development.

2) Pacing

The pacing in House of the Dragon Season 2 is noticeably different from its predecessor. The first episode jumps right in, packing in crucial moments and shocking plot twists—such as the assassination of King Aegon II's son, Jahaerys.

This rapid start contrasts sharply with Season 1, which often took its time to build character relationships and political intrigue. However, in the episodes that followed the explosive premiere of Season 2, the pacing slowed down significantly, allowing for a deeper exploration of the characters' emotions and motivations.

3) Battle sequences

House of the Dragon Season 2 made the battles bigger and more intense. The show sticks to its book roots but cranks up the fights to match what fans expect out of a Game of Thrones prequel.

The way they film and stage the fights shows viewers how messy and brutal the Targaryen civil war, or Dance of the Dragons, is. The team behind the show focused on making the clashes more gripping and serious. The takedowns, battle plans, and the toll it takes on characters is amped up throughout the season.

4) New storylines

House of the Dragon Season 2 broadened its storylines beyond the source material. It delved into character relationships and political intrigue that the book, Fire & Blood, didn't explore.

New faces like Alyn of Hull and Hugh Hammer have joined the cast bringing fresh perspectives and conflicts to the show. What's more, the series aims to shed more light on how the ongoing civil war affects the political landscape highlighting the twists and turns of alliances and betrayals.

1) Daemon Targaryen

Daemon's character in the show has evolved into an amplified version of his ruthlessness and complexity. A notable example would be Daemon hiring assassins, Blood and Cheese, and ordering them to kill Aemond Targaryen out of revenge. A move that backfires completely as the assassins end up killing Jahaerys, the 6-year-old firstborn son of Aegon II, and Daemon's nephew. In the books, it is not specified who exactly gave the order.

2) Alicent Hightower

House of the Dragon Season 2 has put focus on Alicent's inner turmoil and motivational struggles. The series shows Alicent working through political machinations at court against the backdrop of being a dowager queen, and the mother of the king, Aegon II.

It also follows the intimate relationship between Alicent and Ser Criston Cole, portraying her as a woman in a very messy situation, making difficult choices for herself and her family. While in the book, there are hints at the possibility of a relationship between them, it is not explicitly stated.

3) Rhaenyra Targaryen

The core aspects of Rhaenyra Targaryen on the show, her ambition, determination and struggle for power, are in line with her portrayal in George R. R. Martin's Fire & Blood. However, House of the Dragon offers a more direct and nuanced portrayal of her character as compared to the books, which is an account of different perspectives, with her personality filtered through the biases of unreliable narrators.

4) Dragons

In House of the Dragon, the dragons have four legs, aligning with the traditional Western ideas of what dragons would look like. This decision from the creators differs from Fire & Blood, which describes the dragons as having two legs. Although, one might think it is not that big of a change, George R. R. Martin still wants the dragons to be portrayed as true to the books as possible.
