‘House of the Dragon’ star Emily Carey deletes Twitter over fan criticism

When Carey and other "House of the Dragon" cast members attended Comic-Con in San Diego to promote the "Game of Thrones" prequel, uproar broke out.

Carey portrays the younger Alicent Hightower, who is engaged in a succession conflict with her former childhood friend Rhaenyra Targaryen. 

Milly Alcock portrays Targaryen's younger self in the spin-off.

Carey mentioned having the "freedom" to play the young Alicent in a seemingly innocent statement she made at Comic-Con.

There were some holes that needed to be filled, so in order to complete them, Carey sort of started writing. Through this process, she was able to create a backstory, which was really helpful.

"I've never previously had the flexibility to construct a whole human person. Consequently, it was a lot of joy to talk in-depth with her.

Carey continued by mentioning Alicent's "multifacetedness" and how it "gave me a better understanding" of the character.

There are a lot of facets to her. Although I believe many viewers already anticipate her to be the show's antagonist, she said that by casting her when she was younger, there was much more to explore.

However, it appears that such remarks incensed Rhaenyra superfans, who filled Carey's Twitter page with critical remarks. Carey was charged with not understanding the original material well enough, which was the spin-off book "Fire and Blood" by George R.R. Martin.
