Padme is a total cipher. Beyond some lip-service to her role in the Republic collapsing she’s there to give birth and vanish, as the OT dictates. Since the rise of the Empire and the birth of Luke is a given she has no agency in ROTS. Even in the previous films she exists as basic love interest since Anakin has to become evil. She does nothing to act in the face of obvious problems, which would make her have some impact or actual tragedy. A military creation act? That’s good and convenient. Oh wait it’s never mentioned again. Arguably she does a few things in TPM but it’s hardly relevant later. Which is funny because she should have some role in hiding Leia.
