NEW YORK, July 12 (UPI) -- Olivia Cooke says her House of the Dragon character Alicent Hightower is emotionally stunned by the execution of her manipulative father, Otto (Rhys Ifans), in Season 3.
Set about 100 years before the events of Game of Thrones, the show picked up this season with Alicent surrendering her sons' rights to the crown in favor of their older half-sister and Alicent's former best friend, Rhaenyra (Emma D'Arcy).
One of Rhaenyra's first moves as queen is to publicly behead Otto, the man she blames for the coup against her.
New episodes of the fantasy drama air Sundays on HBO.
