The boy with Daemon in House of the Dragon is most likely Aemond Targaryen. He is one of Daemon’s nephews and is central to the family conflict around the Targaryens.

Why this fits

  • Daemon is usually paired with adult male Targaryen characters in recent discussion, especially Aemond or other family members.
  • Public coverage around the show’s latest season has focused heavily on Daemon’s family and the younger generation of Targaryens.

If you meant someone else

  • If you meant the young boy from an earlier season , it could be one of the Targaryen children introduced as Daemon’s kids or relatives.
  • If you meant a scene rather than a character pairing, the exact person depends on the episode and moment you’re referring to.

Quick note

The title appears to be misspelled as “house of drago,” but the show is House of the Dragon.

TL;DR: The most likely answer is Aemond Targaryen.
