since the story is so slow:
spoiler: during the divorce, Sovieshu asks Navier to stay with him even, though she won't be the empress (and you know how stupid Rashta is, and she can't work as being the empress) and she declined. months later at Sovieshu and Rashta's wedding, he sees Navier and says that he wants her back and he loves her. AT HIS OWN WEDDING. he also says that he doesn't like seeing her with another man, and Heinry over hears and he becomes jealous. Navier declines again, of course. Then Navier finds out she's pregnant, and the news eventually spreads to Sovieshu, who thought she was infertile. they couldn't conceive a child for years, and if she was pregnant, that means that he divorced her for nothing (He divorced her because she was infertile and Rashta had convinced him too). He also figures out that the child is not his, it is Rashta's old lover, Allen. He has Rashta under trial, and Rashta tries to escape, but he catches her, and he feels deep loss for Navier. (his fault though). In the trail the emperor was missing because he had been hit in the head, and he had lost his memory. He doesn't know who Rashta is, and he doesn't think he is emperor.
