I've only just seen this, ack! You already know I've seen Ladybug, because of discussion elsepost and backchannel. I *much* prefer Mayura's theme in this episode, Hawkmoth's chord at the end notwithstanding, to the downright ominous creepiness that is the extended Catalyst riff.

Re Nathalie transforming: I'm not all that fond of the construction of that pair of phrases either. I'm going to be playing with wording in fic, or rather Émilie is, on this very subject.
