Passage: As Palpatine declares martial law by transforming the Republic into the Galactic Empire, Padmé remarks to Organa: "So this is how liberty dies – with thunderous applause". After Palpatine names himself emperor for life, Obi-Wan informs Padmé that her husband has turned to the dark side and killed everyone in the Jedi Temple. Unable to believe this, Padmé travels to the volcanic planet Mustafar (with Obi-Wan a stowaway aboard her ship). Padmé begs Vader to escape Palpatine's grasp and flee with her, but Vader insists that, together, they can overthrow Palpatine and rule the galaxy. Padmé recoils in horror, but still tries to persuade him to abandon the dark side. When Obi-Wan emerges from her ship, Vader accuses Padmé of betrayal and uses the Force to choke her into unconsciousness.

Question: Who is accused of betrayal?
Padmé
