After his wife, Princess Rhaenys Targaryen (Eva Best), died at the Battle of Rook’s Rest in season 2, something in Corlys changed. He acknowledged that Alyn and Addam were his sons, and especially after his near-death experience in the Battle of the Gullet — during which his castle, High Tide, was ransacked — Corlys looked to the future even more. After Rhaenyra Targaryen (Emma D’Arcy) successfully took over King’s Landing and claimed the Iron Throne, he pleaded with her to legitimize Alyn (Abubakar Salim) and Addam (Clinton Liberty) as his rightful heirs. Yet she refused.

That tension simmers in season 3 episode 6, and it ultimately makes what happens at the very end of the episode so difficult to watch.

Episode 6 feels like one of those classic Game of Thrones episodes where a lot of little things happen to slowly inch various plotlines forward. There aren’t any enormous battles, dragon fights, or even shouting matches. The show feels rather spread out across its various characters and subplots. One of the few spectacles happens early in the episode when Ser Criston Cole (Fabien Frankel) stands ready to fight to the death against Team Black’s army only for him to be unceremoniously peppered with arrows from a distance. It’s as satisfying for the viewer as it was unsatisfying for Cole himself. The rest of the episode is a lot of simmering tension as the plot inches forward.

In King’s Landing, Alyn of Hull is coming into his own as the de facto Hand of the King. Episode 5 explored how a mystery group of people loyal to Team Green — specifically Daeron’s claim to the throne as puppeted by Ormund Hightower (James Norton) — and now gold cloaks have resigned en masse. Alyn comes up with a solution: leverage Velaryon troops in King’s Landing to serve as the temporary city watch. She requests that he petition Corlys for more.

Alyn catches up with Corlys, who’s been fighting against repeated Triarchy raids, to put the request in. Corlys agrees but remains angry at the fact that Rhaenyra refuses to legitimize Addam and Alyn. “And how many years did it take you to do the same?” Alyn replies.
