I don't know if that will be done, and even if it was it will probably be among the "QoL Tweaks" near the end of the game.
I mean, some characters have weird speech mannerisms, it's part of who they are.
Queen talks in old english, the Merchant always speaks in rhyme, Lily uses a lot of slang, Arty repeats the same thing 3 times in descending levels of formality.
Changing her to be more understandable is not really something the dev thinks about.
Consequences of your actions, you let her get damaged.
But you can turn off yandere mode in preferences.
It won't remove the damage tho, if you want that, poke me on the discord.
