Okay, now that we've sorted names, I think it's also worth mentioning that Ladybug had a go-to person for Miraculous distribution, and it was only Style Queen that interrupted that decision and sparked off Queen Bee as it eventually landed. I have a feeling that if new Miraculous came into Master Fu's care, that Ladybug might seed some of them around to different people, depending on what aspect of that Miraculous she needed most. And that's assuming the new Miraculous are on the same power level as Rena Rouge instead of Queen Bee.

So we might all be right about where Sass goes, depending on the episode and what Sass's power set is. Same for any dragons that come by.

I think we're agreed, as you mentioned, that Catalyst and Paon Bleu can coexist to Hawkmoth, if perhaps in different roles. I also see Catalyst as being someone who won't lie if directly questioned, but the question has to be phrased and delivered correctly or Catalyst will tell a truth without telling the truth about her feelings. She had the opportunity in Mayura, but the question was asked incorrectly and Catalyst read Hawkmoth correctly about what answer he wanted.
