I mean, she straight up dies in CF and VW. She is supposed to die in SS (Which makes no sense because she survives in AM and her role in AM is... nonexistent).
Although she is meant to be Mila 2.0 and... they did a better job at portraying why exactly she needed to die. She was CF Rhea in the base game by the time Rudolf got to her, and Rhea only apparently has a mental breakdown in CF. Mila was also not really in the right state of mind to see the need for her to bow out. Meanwhile, Rhea was only really holding out for her mom to lead and did very little leading herself as a result.
Can anyone name anything Rhea did policy wise besides not join the war between the Empire and the Kingdom?
I can't really think of anything.
Spencer! Devon! Maria! LAWRENCE! NOOOOO!!!
