Rhaena does not die because of Jaehaerys’s death; the event does not determine a punishment or fate for her. In the story people usually mean Rhaenyra and the fallout from Jaehaerys’s assassination, which leads to fear, blame, and escalating war tension rather than a direct fate for Rhaena.

What actually happens

  • Jaehaerys’s death becomes a major turning point in the conflict.
  • The blame and retaliation story centers on Rhaenyra, Daemon, Helaena, and Alicent’s side of the family.
  • Rhaena’s role is not the focus of that event.

Likely mix-up

The name seems to be confused with Rhaenyra or Helaena. Jaehaerys’s death is tied to the Blood and Cheese incident, and the immediate emotional fallout lands on Helaena and the Greens, while Rhaenyra faces political consequences through accusations and loss of support.

In one line

If you meant Rhaena , there is no special fate tied to Jaehaerys’s death; if you meant Rhaenyra , the death deepens the war and intensifies the blame against her camp.
