Lady Felicia had made quite a good case for herself when she asked Alexander to let her control the city, with Alexander agreeing on many of them.
But there were some details Alexander disagreed with.
For instance, he doubted how much Perseus would be able to create chaos in Thesalie given he planned to soon push forward and that should be more than enough to occupy the king's attention for any foreseeable time frame.
Also, he wondered just how influential the lady really was among the people, given that she was a woman.
In this time period, if she were to take the mantle of the city lord and start preaching about Alexander,
even the uneducated city dwellers would be smart enough to guess how she has spread her legs to get that post.
So her claim to be able to placate the public was not nearly as robust as she made it sound to be.
