>TsumuChii suddenly intensified in this episode wow
On retrospect, that's probably a part of S1 that feels strange to someone watching it after it finished airing. Chii and Tsumugi's relationship was established early on outside of the anime via the himitsu's and info available on the Arcade that would further develop their relationship every update. From these, you saw Chii's feelings towards Tsumugi go from that of a mentor to having a complicated mix of (good?) friendship but also frustration and inadequacy. So, when the anime got to the point where their relationship became a central narrative point, it seems to assume that the watcher had knowledge of their relationship developments from outside the show - which is fine for those who watched it as it aired, but isn't really an option for people watching it afterwards.

>Bitter Gavv arc?
I immediately felt like it was Dark Ryuki vibes personally, especially at the start when Dark you-know-who is initially reflected in the mirror.
