Why hasn't Amicus grown at all? In this work, he comes across as extremely immature, completely unlike what an emperor should be. Clearly, in the main story of Adastra, he had enough confidence and ability to face any challenge, and before the humans left, he showed signs of having egalitarian thoughts (except on the day of the date when he acted like a jerk out of frustration from the plan failing). Yet, in the current timeline, he somehow appears to me as an arrogant and incompetent figure. For now, I'm interpreting it as him losing his composure due to worry about the human's situation, and I hope there's a better explanation later on!
