A night at Sakurako’s moves Minami to tell her Hitoe’s location, and when they find her covered in butterflies the worst is feared. Alas, “only” her dog is dead and attracting the insects; she merely took a non-lethal dose of sleeping pills and soon wakes up. Not shortly thereafter, Hector barks from outside, announcing he’s found what Sakurako was hoping to find: more bones. Specifically, the bones of a young woman; Minami and Hitoe’s friend Futaba. And that’s far from all that’s unearthed this week.
Minami recounts the tale of how Futaba showed her and Hitoe this abandoned cabin in the woods, and they made it their home, their place where they belonged. All three of them had their problems, but Futaba was the worst, and soon wanted to enter a suicide pact with the other two. Hitoe agreed, but Minami didn’t want to die, so she ran. When she returned later, Futaba was dead, having hung herself, while Hitoe injured her hands trying to save her.
Minami buried the body, and that was that. Only…Sakurako-san wasn’t born yesterday by any stretch, and Futaba’s bones tell her a far different story. Not a story of Futaba hanging herself as Hitoe struggled to stop her, but a story of being strangled to death, as indicated by bones that would not have been broken by hanging, and the dubiousness of dying while hanging so low her feet touched the ground.
Hitoe can’t keep up the fiction any longer, though she kept it hidden within her memory for so long, it flows out like a river through breached dam, all anger and despair. Futaba gave her an ultimatum: she’d either help her kill herself, or she’d kill her, then commit suicide. It was an impossible situation for Hitoe, who comes out and blames Minami for running. Had she been there, maybe Futaba would have kept it together a little longer (though considering both she and Hitoe were already considering suicide when Minami fled, I doubt it).
Isozaki is able to calm Hitoe, and puts all the blame on himself, not for failing to see the pain his three students were in, but for seeing the pain, and turning away, not wanting to be hurt himself.
After burying Futaba, Minami and Hitoe drifted apart, partly because Hitoe started seeing other friends, partly because Hitoe reminded Minami of what happened to Futaba. Then she met Hanabusa, who she waxes poetic about as if her mind had been programmed to say these things. But it wasn’t; she simply fell victim to the honeyed words of a criminal mastermind, just as Hitoe would, and just as many other victims have.
Sakurako knows Hanabusa never loved Minami—that he’s incapable of loving anyone unless they’re bleach bones—and that Minami was just another pawn in his game. The thing is, she doesn’t really need to be so blunt about all these things at this particular time. For someone so good at detecting, she fails to read the room, and turns her back on Minami, who can’t handle what she’s saying and tries to stab her with a palette knife.
But Sakurako doesn’t get stabbed, because Shoutarou comes between her and Minami, catching the knife in his side. Remembering her brother, who apparently drowned in a rainstorm, she shouts out Shoutarou’s name.
But it’s all okay; the stabbing wasn’t precise, nor was it lethal. Shou will be fine. But Sakurako isn’t. It was too close a call for her. As she hits the home stretch on tracking down the “abyss” that is Hanabusa, Sakurako has unilaterally decided she and Shou must part ways. It almost feels like a breakup…because it is, and Shou is heartbroken. But the bottom line is, Hanabusa is a dangerous, brilliant son of a bitch, and while Sakurako loves bones, she never wants to see Shoutarou’s.
Will Shoutarou really accept this? He’s too shocked and overwhelmed to protest here, but once he’s discharged, I wonder how Sakurako will keep him away, and whether he’ll honor her selfish desire to go it alone with Hanabusa. I’m hoping he won’t, because as the tear Sakurako sheds indicates, these two people belong together. Call them soul mates, if you will.
