Why House of the Dragon’s Rhaenys didn’t kill the king (just everyone else)

House of the Dragon’s ninth episode was on the more quiet and contemplative side, right until it wasn’t. After Viserys’ death, a castle lockdown, and the coronation of a new king, there were sure to be a few dissenting voices, and the loudest among them was Rhaenys Targaryen, the most recent Westerosian to declare her loyalties to Princess Rhaenyra and the Blacks.

But while the motivation of Rhaenys’ theatrical entrance to the new king’s coronation aren’t hard to miss, the reasons behind her carefully intimidating exit might be. While she had the chance to make a fiery escape and end a few conflicts in a flash, Rhaenys also knew that the fate of Westeros isn’t as simple as a few burned bodies.

King Aegon II’s reign began with a less than auspicious moment as, at the very height of his praise from the people of King’s Landing, Rhaenys Targaryen smashed through the domed roof with her dragon Meleys, surely crushing dozens of peasants. Meleys made their way to the podium that contained the royal family, and stood menacingly before Aegon. Game of ThronesFans might think the scene would end with a quick death. But Rhaenys, her dragon and all the rest of the party simply walk away. There’s a notable reason for the restraint.

Practicality is the largest reason. An entire audience cheered for the new King. And murdering him or his host would result in regicide. Sure, Rhaenyra could have stepped into the power vacuum, but The Realm’s Delight would have instantly been seen as a terror, and the Queen Who Never Was as a murderous accomplice without even a shred of honor.

Rhaenys’s single act would have caused a crisis in Targaryen dominance, causing the whole Targaryen family to fall into deep weakness. And an act of outright violence and treason could have sent King’s Landing (not to mention the rest of Westeros) into total chaos. This kind of conflict is why wars are fought, and winning is only supposed to be worth it if what you’re fighting for is still around when you’re the last one standing.

Aside from the political ramifications of roasting the royal family, there’s also an equally strong superstitious reason Rhaenys didn’t kill Aegon: kinslaying. Westerosi traditions say that no one can be cursed more than kinslayers, which means that people who murder their family members are frequently plagued by terrible tragedies, and considered monsters.

When the full Targaryen civil war does break out, kinslaying will be a nearly inevitable side effect, but for Rhaenys, it’s possible that the idea of killing so many of her own family, in such a short time, in front of thousands of onlookers, was simply too much to bear. While the eventual death and consequences of letting everyone live may seem obvious, a simple act like this proves that Westeros’ traditions haven’t all fallen away just yet, no matter who sits the throne — at least for now.

Even if we don’t know the exact reasons for her momentary mercy, it is clear that Rhaenys’ actions during Aegon II’s coronation were a signal of defiance against the new crown and the perceived treason that Queen Alicent, her father, and her children have committed. Even if no members of the royal family died, Rhaenys’ slight (and her probable murder of many King’s Landing citizens) are the first real shots of the Dance of the Dragons and the wider war to come.
