House of the Dragon: How is Ser Steffon Darklyn related to House Targaryen?

In this week’s episode of “House of the Dragon,” Queen Rhaenyra (Emma D’Arcy) and her team faced a significant shift. Following the tragic demise of Princess Rhaenys (Eve Best), their most accomplished dragonrider, Rhaenyra was left with an insufficient number of dragonriders but a plentiful stock of dragons hibernating in Dragonstone’s caverns. The previous episode, titled “Regent,” concluded with Rhaenyra and her son Jacaerys Velaryon (Harry Collett) discovering that there might be records of Targaryens who had wed outside their dynasty and that their offspring could still possess sufficient Targaryen lineage to tame a dragon.
