Thematically, I really liked this episode. Luna loved Livius the way he was, but ran away after what he became. Nike on the other hand, only knew Livius at his worst, and soaked her way to his heart. Luna had to admit she lost because she couldn't accept all of what Livius was, but Nike not only could...she did.

So...Nike's boobs definitely have grown. It wasn't just the one scene where Luna was groping her, Nike was larger in the bed, larger practicing at night, and well endowed in the next episode as well. She grew tall so fast, but now she's finally growing out. She'll make a splendid queen after all.

What is sort of weird is how contemporary Nike's clothes are compared to the rest of the series. The Sun and Ocean kingdoms both have sort of 19th century clothing, but given that the Rain Kingdom appears to be old-timey Korea or China from the first episode and flashbacks, they have very modern clothing. Each time we see her in Sun Kingdom clothing, she matches. The rest of the time she has her standard jumper/one-piece from the 1970s and the shirt, tie, and tight-waisted skirt on the roof (also very mid 20th century), among others. She's got the legs for it (as far as anime character legs go...), but her clothes seem so out of place compared to the rest of the world that we've seen. It's not bad, just weird.

I assume all her clothes expose her legs because otherwise she'd rip them or get them dirty running all over the place like the barbarian she is.
