Also this has definitely been pointed out before but the fact that Kaoruko is the first of them besides Hikari to choose to shed her cloak at the end, paralleling the way she was the first to lose it during Wi(l)d Screen Baroque is insane. Kaoruko's arc in this movie is one of the best especially in little blink-and-you'll-miss-it moments like this, and that's saying a lot.
