This episode opens with an upbeat ditty playing as Nanako and Tomoko browse dresses for Nanako to wear at the Sorority's post-midterms party on Fukiko's private ship. It's the last day of post-midterm holidays, and the next day, exam scores will be posted. Tomoko aims to be average. Nanako is concerned about her score (although still not as much as your average Sorority member), and Tomoko is like "You get good grades, you're good."
The next day, we soon see that Nanako and Mariko ranked in the top 50. Their celebration is cut short by a Sorority candidate named Nakaya Junko crying and running away because she ranked 73rd because she got too sick to write anything on the first day of exams. (Tomoko notes that's still better than what she got.) The Sorority being as compassionate and sensitive about its members' well-being as it is, you know Nakaya will be fine.
In English class, Nanako thinks about how it's been three months since she fell down the rabbit hole that is this school. She feels more settled, and like weird shit is less likely to happen at this point, hahahahahaha.
Nanako's perspective reconfirms that even though Seiran has enough architectural and pastoral beauty to make Marie Antoinette's Petit Trianon jealous,
At this point I mention the similarities between Oscar, Rei, and Claudine's character designs to my girlfriend Amy and tell her what I think their differences are. And then she pulls up this picture, this one, and this one, and proves that they are triplets. (Amy: "They're cosplaying as each other, basically.")
Anyway, Fukiko pulls a pretty cruel bait-and-switch. (Not sure it's intentional, since I'm not sure she is cognizant of how hurtful a good amount of her behavior is, despite her guilty hallucinations of Rei a couple episodes ago.)
Since pleading with Fukiko alone doesn't work, Nakaya asks her two best friends to help her out,
Nanako stands up to vouch for Nakaya, though, and tells Fukiko she doesn't think the rules by which she's being judged are valid for good measure. I've seen Nanako criticized as a weak character, but lol she's the only one besides Kaoru vocally questioning Fukiko at their school for a good while in this show. (It reminds me a little of Akane from Psycho-Pass being called weak early on in the show even though she acts on what she thinks is right contrary to the shitty system that controls her world from episode 1 on. She does act in ways you would expect of a rookie cop, like Nanako acts in ways you would expect of a 15 year-old freshman. They both show poor judgment at points, but neither of them is weak.)
Fukiko ends the discussion by being like "Who do you think you owe your Sorority membership to?", leaving Nanako in shock because it confirms the rumors that she didn't get in fairly that she didn't think were true, because they were predicated on her being complicit in getting in unfairly. Mariko gives her the obligatory "OMG don't ever oppose Fukiko, what was that" speech and tells her to apologize to Fukiko with a big bouquet of red roses.
But first we see her asking two of her Oneesama, drinking tea and smoking in their private waterfront clubhouse(?) for help. Obviously that doesn't work.
In case we can't tell that Fukiko is being mean, we see her face ominously shadowed as she plays the same piano tune she always plays.
We see the party on Fukiko's private ship the next day, where Nanako can't enjoy herself. Mariko tries to cheer her up (and get her to apologize to Fukiko if she hasn't), but Nanako is just disturbed by how Nakaya could be kicked out just because Fukiko wants it, and how her admittance might have happened the same way.
Fukiko breaks out the champagne, and the party continues at her beachside mansion. Nanako steps outside, and Fukiko follows with her face completely blacked out, which has only happened so far in creepy scenes- and only with Fukiko, aside from Rei when she was high and thought Nanako was Fukiko in the previous episode.
The bird motif seems to be replaced by moths in this episode. I guess the director wanted to switch it up a bit.
Fukiko also somehow knows about Nanako exchanging letters with Takehiko. She presses a promise to stop writing to him out of Nanako, but Nanako intends to keep writing to him, and how would Fukiko find out anyway. (Nanako isn't thinking this through too well, because why wouldn't it be possible for Fukiko to find out it was continuing if she found out about it in the first place? That's some powerful wishful thinking.)
Nanako and Tomoko talk on the phone later, but it's interrupted by a call from Nakaya, who is waiting at a pay phone nearby.
Nakaya tells Nanako about how she's looked up to the Sorority since she was a kid, assuming its members would have the character to justify the prestige and glamour associated with them. Now she realizes it isn't true, and that looking back, she hasn't had a single happy moment as a member of the Sorority. Nanako is shocked because what Nakaya is saying is how she feels but hasn't articulated, and she isn't alone.
Nakaya admits she had a grudge against Nanako for Fukiko's favor towards her, but now sees that she misjudged her.
The next episode will feature Kaoru's basketball comeback, and conflict involving her illness and Mariko.
