David Tennant's Son Ty Will Make His 'House of the Dragon' Debut

Following the time jump in the series, Olivia Cooke will now play Queen Alicent Hightower, taking over for Emily Carey, and Emma D’Arcy will play Princess Rhaenyra, who was previously played by Milly Alcock.

Ty appeared in the episode six preview dueling with a knight.

The teaser also featured Queen Alicent plotting for her son to take the Iron Throne, instead of Princess Rhaenyra. “You will be our King,” she declares.

There’s a fun Doctor Who connection throughout the series: Matthew Needham, Steve Toussaint and Matt Smith are all alums of the show, in which Ty‘s dad played the Fifth Doctor.

He also previously appeared in the Doctor Who special The Five(ish) Doctors reboot, including Matt, in 2013.
