A thing that struck me about God Emperor was the ghola of Duncan Idaho, his constant whining throughout the book really annoyed me. By the end I really couldn't stand him as a character, and the main reason he helped Siona assassinate Leto, and on his wedding day no less was not for some high minded purpose like freedom or other, but because Hwi Noree would not leave Leto for him. And then to top it off he savagely kills Nayla for following his orders when it led to Hwi's death, because he did not know that Hwi was in the royal cart with Leto. This sounds suspiciously like a character from Earwa, Achamian leaves the service of Kellhus and becomes a hermit for two decades because he lost Esmenet. And Kellhus says that he will kneel before him at the end, if Akka actually succeeds in getting to Kellhus there might be a confrontation.
