chunk: By the time the plot reaches Act Three, Thermusa is very angry because she knows King Artabanus is lusting after someone else. She tells this to Vardanes, who decides to use this to destroy Arsaces and take the throne of Parthia for himself. Arsaces asks for Evanthe’s hand in marriage in front of King Artabanus. Artabanus decides to let Arsaces have Evanthe because he promised Arsaces anything he wanted for being such an awesome child. Evanthe tells Arsaces that King Artabanus loves her, to which he replies that he loves her more. Vardanes then tells King Artabanus that Arsaces is a traitor.
