We're now at the halfway point of House of the Dragon season 1, and that means there's going to be a major character change. Milly Alcock and Emily Carey's time playing Princess Rhaenyra Targaryen and Alicent Hightower is seemingly at an end after the release of episode 5 this week.

A new sneak-peek teaser that dropped Sunday night confirms that Emma D'Arcy and Olivia Cooke will now officially make their debut as the adult versions of the lead characters in House of the Dragon episode 6. They will presumably maintain those parts for the remainder of the series.

D'Arcy and Cooke were among the first ones announced in the cast back in December 2020 when plans for the Game of Thrones prequel were getting into gear — showrunners Ryan Condal and Miguel Sapochnik revealed they would be the leads ofHouse of the Dragon. But in a surprising move, the series began with Alcock and Carey playing younger versions of the two main characters.

If you've yet to see the teaser for the upcoming episode, brace yourself ... things are heating up!
