- Kuroda's memory implies he saw Kohji's corpse.
- Kuroda's already aware of Conan being the mind behind the man and directly asks for his help.
Given that we didn't see Koji's body until Hyoe looks at the case details, it's likely he was there.
And he's not the only one focused on Shinichi/Conan...
- Wakasa's approaching Conan cautiously and trying to test him, while also giving him hints.
...and what is the relationship between she and Hyoe?...
- Kuroda and Wakasa both show hostility toward the other due to suspicions about who the other could be.
It really strikes me, giving the red herring vibes I'm getting from both of them, that they aren't true antagonists (e.g., Gin). We also happen to have two protagonists arrayed against each other due to a misunderstanding (Shuichi/Subaru and Rei/Toru/Bourbon), so it wouldn't be a stretch to see it happen between Rumi and Hyoe.
- Wakita's various actions make it look like he wants to get close to Kogoro, a bit too eagerly if you ask me.
- Despite how Wakita is supposed to be new to the place he works, and the case is during the summer (the next case with Wakasa acknowledges that autumn is there and the previous cases were during summer), yet he knows that the place has started serving sanma since autumn. Menu changes are rare for a new employee to learn about, if it's been a while since they were incorporated, in my experience.
Just like Rei/Toru—thus giving the impression that, since he (a self-proclaimed detective working in an eatery next to the Mori Detective Agency) turned out to be Bourbon, Kanenori (a self-proclaimed detective working in an eatery next to the Mori Detective Agency) will turn out to be Rum. That really
strikes me as a red herring.
I'm really not sure if he's a BO member (who's not Rum), or if he's Rei's/Toru's boxing coach, like Chek once suggested (maybe such a connection to Rei/Toru means he also
has a connection to the NPA).
- Mary is using Masumi as an intermediary and moving from place to place, but she's to some extent soured on the idea of meeting him after the Soul Detective arc.
Presumably because Shinichi/Conan "is nothing like the boy we met 10 years ago." Any ideas as to what the difference between actual
7-year-old Shinichi during Ripples and technical
7-year-old Shinichi/Conan is? Was it something that happened during Detective of Souls—him carelessly dropping his bow-tie, perhaps? Her realizing that his presence is a sign that someone's about to drop dead, perhaps, hence the "all kinds of monsters lurk in the dark" comment? Beyond those, I'm just not sure what it could be—a lot of it has to do with the fact that she wanted to meet him before (903–905/787–788) Detective of Souls, but by 953/864, she's telling Masumi to not let her guard down around him and seemingly comparing him to a monster lurking in the dark.
- Chikara and Shuukichi are involved with shogi and thus meet in that context.
And that's a key point of this arc, to me. Rum's signature act is the murder of a shogi player, one who inspired his future brother-in-law to become one, as well—and said future-brother-in-law was also the son of a man who apparently got himself killed by looking too closely into the murder, and the brother of an FBI agent who infiltrated the BO—who took the lead in the first case of the Rum arc (899–902/785–786), and went on to mention Koji to Yumi, leading to Shiho/Ai telling Shinichi/Conan about his name being on the APTX list, thus kicking off the Koji Haneda plot thread (945–947/849–850). And who was Shukichi's opponent in both those cases? Chikara, whose name was actually provided to us... but not in a name box. So we have Rum, the Akai family, and Shogi...
Also, Rumi seems to have a shogi piece with her—it would even appear that Koji was clutching a shogi piece in the palm of his hand as he held the scissors in a defensive grip.
- The message "ASACA RUM." How would Kohji know the name Rum or that it was significant or that anyone could derive the real meaning? (Unless his message was altered or he was in deeper with Amanda's intelligence agency ties than we thought...?)
That's assuming the message is just
ASACA RUM—which assumes that there isn't
more to Koji's dying message than the mirror.
“Life is infinitely stranger than anything which the mind of man could invent. We would not dare to conceive the things which are really mere commonplaces of existence. If we could fly out of that window hand in hand, hover over this great city, gently remove the roofs, and and peep in at the queer things which are going on, the strange coincidences, the plannings, the cross-purposes, the wonderful chains of events, working through generations, and leading to the most outre results, it would make all fiction with its conventionalities and foreseen conclusions most stale and unprofitable.”
“Education never ends... it is a series of lessons, with the greatest for the last.”
