You force the MC to have an active interest in her, I already told you that I think that there are easy ways to bypass this and still have the king talk about her.
And that MC has to get angry at Alexanders words indicates that they feel something for her. This indication is enough to have at least two people react negatively to it.
It may be few words for you, but as you see readers still pick them up. As author that’s something you should keep in mind not just when it comes to the mother but generally if you write about MC’s feelings. Not all the time it’s possible to allow the player to do what they want, but you still can give choices that at least give control to the player about their own MC if not about the story. And tjis is very important when it comes to relationships between MC and npcs no matter the nature of that relationship (I hate it as much if a game assumes or forces me to dislike a NPC as I do for the opposite and everything inbetween)
If it’s not important I don’t see what speaks against taking those out in favor for more ambiguous reactions by the MC.
Besides @augustus27, who wants to stir chaos and just hopes to beat Alexander up…
