House of the Dragon's next episode will feature a 10-year time jump, and in addition to the roles of Alicent and Rhaenyra being recast, the baby Aegon II Targaryen is grown up. An actor who comes from a famous acting family will play the role, it's been revealed.

Ty Tennant--the son of Doctor Who star David Tennant and the grandson of another Doctor, Pete Davison--will play the teenage Aegon in House of the Dragon.

Tennant previously appeared in the movie Tolkien as well as the TV shows Doom Patrol and War of the Worlds. House of the Dragon is arguably his biggest role to date. You can get a glimpse of Tennant in House of the Dragon in the Episode 6 trailer below.
