House of the Dragon is back on our screens with the first episode premiering on Sunday (or Monday, depending on where you are in the world), and viewers have taken to social media to share their thoughts on the new episode - as well as their slight confusion at just where we have left the storylines. 

After all, it has been two years since the season one finale aired back in 2022, so we think it’s fair enough that some people might need their memory jogging - so with spoilers for season one inbound, here’s everything you need to know about the plot for season two…

The set up 

In season one, King Viserys struggles to welcome a son, and so proclaims his daughter Princess Rhaenyra as the Heir to the Iron Throne - especially since the other potential Heir, his brother Daemon, deeply lets him down and isn’t considered trustworthy - particularly in regards to becoming the next King of Westeros.

Set 200 years before the events of Game of Thrones, this epic series tells the story of House Targaryen.

After proclaiming Rhaenyra his Heir, he tells her a story that only Targaryen Kings of Westeros have known throughout the generations - that King Aegon I prophecised ‘the song of Ice and Fire’, a terrible crisis which would need to see a Targaryen on the throne as ‘the prince who was promised’, who will unite the realm and save the world.

Rhaenyra's mother Queen Aemma dies in childbirth

Following Rhaenyra’s mother Aemma’s death, King Viserys weds Rhaeneyra’s childhood best friend, Alicent Hightower, who gives birth to two sons, Aegon and Aemond. Alicent’s father, the Hand of King Otto Hightower, predicts that war will be inevitable as the great houses won’t want Rhaenyra on the Iron Throne when Viserys has sons who could become King instead, alarming his daughter. 

Rhaenyra and Alicent’s fallout 

Relations between Rhaenyra and Alicent sour after Rhaenyra’s actions during a night out with her Uncle Daemon, where she is seen being intimate with him, and subsequently sleeps with her Kingsguard, Ser Criston Cole.

Ser Otto tells the King about the reports, who reacts by removing Otto as Hand of the King and sending him away. Upon learning that the accusations were true after initially believing Rhaenyra swearing that Daemon never touched her, Alicent turns against Rhaenyra.

Ser Criston Cole, who fails to convince Rhaenyra to run away with him after falling in love with her, despite his oath as a member of the Kingsguard, also turns against her, allying himself with Queen Alicent.

Queen Alicent falls out with her old best friend Rhaenyra

Alicent and Rhaenyra go on to welcome children with their respective husbands, where the animosity continues as Alicent (correctly) suspects that Rhaenyra’s sons Lucerys and Jacaerys are illegitimate. The infighting trickles down to the children, and during an argument gone wrong, Aemond accuses Luc and Jace of being illegitimate, and Luc attacks him, resulting in Aemond losing an eye.

Rhaenyra is betrayed by her half-brother Aegon

The family reunite in a moment of solidarity in the hours before the King’s death. However, on his deathbed, attended to by Alicent, Viserys mutters about Aegon being ‘the prince who was promised’, and Alicent assumes that he is referring to their son Aegon, and that he had changed his mind about the line of succession.
