Eriphyla's awakening is still ongoing, though Ember should be giving her the general rundown (you're a senshi, there's a war going on, etc). That said, Charice is still someone who lacks a lot of situational awareness, and is highly oblivious to her surroundings, once she gets lost in her daydreams
I'm... not exactly looking for like, Ida coming to the rescue, but maybe she could show up and be like 'hey you need to pay more attention to things or you're going to have a bad time', and they get to talking, and Ida finds that Eriphyla is part of her Koronis 'family'?
