His grandfather is Peter Davison, the fifth Doctor on the long-running British sci-fi series.
He’s also the son ofDavid Tennant, who played the 10th incarnation of the Doctor.
Ty is Georgia’s son from a previous marriage, and David later adopted him.

House of the Dragonmarks the biggest role for Tennant yet.
It’s unclear how long we will see Tennant in the Aegon role.
Actor Tom Glynn-Carney will eventually take the lead as Aegon following more time jumps.
