‘Kaya and Sayuri froze, but Madame Lumina had had just about enough of this nonsense.’
Yeah… that sentence looks a bit awkward to me. It’s the ‘had had’, although it is something people would say it kind of looks odd written down. Maybe if I used an apostrophe for the first had; Madame Lumina’d had just about enough… is that better? I suppose I could just rephrase the whole thing.
