As BSG’s President Roslin said, “Alright…Next Crisis!” Kumiko may be dealing with a widening rift between her and her sister, but that takes a backseat to a more pressing issue that affects the entire band. It’s also the reason we’ve gotten so many close-ups of Asuka’s sadface: her mom is making her resign.
Taki-sensei refuses, but after her mom slaps her (an incident Kumiko happens to witness), the mother and daughter go home, and Asuka returns to school bright and cheery like nothing happened, she just plain stops showing up to band practice.
The sudden loss of Asuka, and all the swirling rumors about it, instantly, negatively affects the band’s performance in practice on the eve of a very public performance at a big train station. Taki is not pleased with this, and basically peaces out and leaves President Haruka to deal with it (which is the right move to make, rather than continue trying to focus a clearly rattled band).
Haruka steps up to the plate (well, the lectern), and performs admirably, telling the band, essentially, that all this time they’ve built up Asuka as someone “special” and irreplaceable; but that’s not really the case. And now it’s up to them to support her for once, by bearing down and putting on a show they, and she, can be proud of, in hopes she comes back. That’s all they can do.
The day of the station gig, sure enough, Asuka is there with a bright smile, ready to see what the band can do in her absence. Haruka wrests control of a massive, unwieldy baritone sax and belts out a badass solo. Taki suggested the solo to “shake things up”, and it worked: the performance boosts the president’s and band’s confidence as the Nationals draw nearer.
Asuka’s future with the band is still unclear, but the band will survive. As for Mamiko, there’s something very foreboding about the episode ending with her putting on her shoes and walking out the door of her family’s home.
