For the Lady Luck and Matagot AU...when does Marinette start to get sick? Do Sabine and Tom panic over their girl, pulling her from school so she can rest and recover, only for her to get worse. Less time in school, more time to use her miraculous...Maybe being so close to Tikki (in the same house, even!) Slows down the decline, but a broken miraculous just can't be handwaved away as a nasty headcold.
Adrien may find himself facing a new dilemma- once they have the wish, what will he do? Will he bring back the mother that he may be realizing wasn't so stellar? Or will he use all that power to save his best and only friend, who is destroying herself for *his* sake?
I have plans for a lot of drama revolving around this particular plot-point, but in case I do actually write this out properly, Iāll avoid giving any specific spoilers. However, what I can say for sure is that Sabine and Tom do eventually notice somethingās wrong as Marinette continues to worsen, and it deeply concerns them, (as well as her teachers and few friends at school.)
As for Adrien, he definitely has mixed feelings about everything thatās happening to Marinette, but itās a constant struggle for him between his own desires and the ones being fed to him through his amok.
I know thatās kind of a vague answer, but thereās only so much I can say without ruining the endgame of the storyline. Hopefully it helps though. :)
