The encounter with the Princess of Disaster left Himeno deeply insecure, and now she feels incapable of confronting her. She decides to seek information about her, and the younger knights take her to Leafe's garden to see where the whole ordeal began. Eventually, something is revealed that we had already hinted at in the previous episode, but which, for obvious reasons, has a profound impact on Himeno. I really appreciate how the characters' reactions in this anime feel organic and how they don't overcome their emotional issues so easily; they carry them with them even if it's not overtly obvious.
