My thoughts on File 1032-1033:
Case Deduction
A basic “how-dunnit” case. Zenda moved the car manually by the tire, which resulted the dirt on her right arm and palm, which explains the tire mark and the movement of the four-leaf clovers that Ayumi spotted before the corpse was found, in order to fake her alibi with the photo of a corpse-less tree that is actually the wrong tree (because the car was blocking the real corpse tree). That is why she made sure to cover the windows of the right side of the car with cardboard, so that no one but her can see the corpse even when they exit the car. Prior to meeting DB, She also drugged the woman Uruma was keeping in his villa, then locked her in the closet until the murder happened (and was lucky to have her faint due to her claustrophobia even after waking up) and finally after killing him, she unlocked the closet and smeared her hands with his blood to frame her and then dragged Uruma’s corpse to the designated encounter site.
Wakasa Rumi’s memories
My suspicions about this proverb about the kakugyo (watchtower bishop) and Kohji asking if Rumi (someone) will still kill him despite that, as well as Rumi calling him foolish, is that Kohji surrendered to his death and was calmly ready to use the bishop piece as a dying message (hence fitting with the proverb “future holds a good move…”, since its move will take effect in the future after he dies), and Rumi (who is implied to be BO) had come to his room with intentions to kill him before Rum got to him (wild shot: because she wanted to prevent APTX usage by Rum), but Kohji, having an inkling on her inconsistent intentions with Amanda’s killer, convinced Rumi, who took his proverb as the piece being his good luck charm (hence the flashback trigger from “good luck charm”), to pretty much let him make his stand against Amanda’s killer with his “good-fortuned” retaliation (which actually meant to leave the bishop piece as a crucial part of the dying message and die by Amanda’s killer’s hand), thus leading to his death and her calling him a foolish guy for his martyr-like act, and perhaps also because Rum took the bishop piece from his hand in the end (since he doesn’t have it on his hand in her memory), making everything seem like a failed retaliation. That would mean that Rumi was there to see him orchestrate the dying message and know what the relevant pieces are (whether she takes anything later or not) and hid herself when Rum came in to kill him (since this was noted as Rum’s mistake alone, and not any other BO figure). Either Gosho is being fair with the flashback implications (meaning that Kohji indeed wondered if she was gonna kill him), or he is going to extreme lengths of highlighting misleading snipbits from completely different contexts of her memory to fuel the Rum mislead. Personally, I’m leaning towards him being fair on this, since unlike Conan during swimsuit and Ran during Chinatown, Rumi doesn’t seem to have recollection issues (since she boldly calls Kohji foolish, meaning she remembers Kohji’s actions), so it doesn’t make sense for her to recall out-of-context snipbits when she already remembers the context (unlike Ran and Conan).
I don’t think Kohji’s proverb necessarily excludes the piece’s promoted side (uma) from being relevant, since the proverb can just be his way of emphasizing the piece as a whole to be important for later. The fact that Gosho revealed the piece with its uma side in File 1008, and then highlights the piece with a kaku proverb here makes both sides candidates (and perhaps it’s the least obvious one with that logic, uma, seeing as we had the Rum horse easter eggs).
Wakasa Rumi’s pain
Conan concluding from Rumi just pressing on her eye area that she has monocular vision is to me just another Gosho attempt to mislead, because her pressing like that in general can also be a sign of headache/migraine. This is yet another symptom of wearing unfit glasses imo. Also, her excuse about feeling “anemic” is an interesting choice, since it immediately reminds me of Vermouth, who made the same excuse for Masumi collapsing in File 822.
Conan’s fake identity examples
“Such as a Detective, who’d change it to something that makes it easier to extract information” –> Kuroda “Or a Spy, who’d turn into someone well suited to the place they’re infiltrating” –> Wakita “Or Someone who’d pose as someone else to deceive people…” –> Wakasa
So in other words… Tsutomu is “Kuroda Hyoue the Superintendent” to extract information easier. the Spy (helping Gin) is “Wakita Kanenori the Chef” to get well suited to Iroha that he’s infiltrating. Vermouth is posing as someone else (“Wakasa Rumi the deputy homeroom teacher”) to deceive people.
