On one hand she did inadvertently give Marie inspiration but like that's if you REALLY want to be generous in giving her credit. But no in all reality thanks for the inspiration but you didn't come up with shit.
Not that it really matters either way. The King KNOWS she's full of shit and getting her ideas from Marie so its not like her trying to claim credit for this is going to boost her estimation in his eyes. If anything it'd just boost Marie's.
