hit HBO series “House of the Dragon,” deleted her Twitter account after she was inundated with criticism about “humanizing” her villainous character.The controversy erupted last month when Carey appeared at Comic-Con in San Diego alongside fellow “House of the Dragon” cast members to promote the “Game of Thrones” prequel.Carey plays the younger version of Alicent Hightower, who is locked in a battle for succession with her childhood friend-turned-rival Rhaenyra Targaryen. The younger version of Targaryen is played in the spin-off by Milly Alcock.As in “Game of Thrones,” when viewers sided with either the Starks or the Lannisters, the premiere of “House of the Dragon” ignited a similar dynamic in which fans lined up behind either House Targaryen or House Hightower.At Comic-Con, Carey made a seemingly innocuous comment about having the “freedom” to portray the young Alicent.“There were some gaps that we had to fill, so to figure it all out I sort of started journaling, and … managed to come up with some form of backstory, and it proved to be very useful,” Carey said.“I’ve never had the freedom to create a whole human being like this before.
