Rhaenyra Hasn’t Told Jacaerys About Aegon’s Dream Yet - Why?
Rhaenyra’s heir is still unaware of Aegon’s A Song of Ice and Fire dream
House of the Dragon’s season 2 premiere marks theGame of Thronesfranchise’s triumphant return to Winterfell, and more notably, the Wall.Lord Cregan Starkbrings Rhaenyra’s eldest son and heir, Jacaerys Velaryon, to the Wall during his visit to the North, where the two discuss the purpose of the Wall and what it keeps out – not Wildlings, but “death.”Jacaerys’ response to Cregan’s White Walkers reference is a look of surprise and confusion, which means that Rhaenyra hasn’t told Jace about Aegon’s dream as ofHouse of the Dragonseason 2, episode 1.
Viserys emphasized the importance of Aegon’s dream being passed down to the heir to the Iron Throne, so it’s shocking that Rhaenyra hadn’t told Jace about the Targaryen prophecy upon being crowned the Black Queen. Despite how crucial it is to pass along this information,Rhaenyra likely hasn’t told Jacaerys because she hasn’t had the time. Directly after being crowned, Rhaenyra sent her sons as envoys and was still working out politics with the Greens, so she was more focused on the urgency of building alliances than informing Jace of Aegon’s dream. Upon Jace’s subsequent return home, the two are overcome with their grief regardingLucerys Velaryon’s death.
