Jellyfish's last episode was rough on my heart.
And in the preview we see Kano being depressed, which means this episode is looking like it'll be rough too.
Yeah the current high drama arc isn't the fluff you might want from a CGDCT show, but I really appreciate the way it's done. It seems relatively well grounded and I think the characters are all acting in a very consistent and "realistic" manner according to what we know (or have just learned, talk about presenting backstory) about them. I don't watch external previews for future episodes. I usually take my anime as they come, when they come.
I had the impression that they took a very effective "show don't tell" approach to both current and past events in this episode, with little commentary added (e.g. mama Hayakawa's manipulative approach to negotiation was super well presented without overplaying it too much or making her an obvious villain). In the later parts it felt more like Kano was reliving some of her uncomfortable experiences, allowing us to learn of the past through her eyes, rather than having her explain it to others (which is what I meant by "commentary").
Direction, acting and animation were top notch in this one.
