“House of the Dragon” sets the tone for its second season by closing its first episode with an assassination. “A son for a son,” as the terms are described, and the premiere is titled. Daemon Targaryen (Matt Smith) gives the order to a Gold Cloak in King's Landing who remains loyal to him and Rhaenyra Targaryen (Emma D'Arcy) – but mainly to Daemon, who is a doer and not a thinker.
