Hyoue - Currently someone swapped, but I think he might be part of a backstory that isn't known yet, so we still haven't "met" his real ID in the story yet if that makes any sense. I think he knew Elena or Mary.

I acknowledge it's not a bad idea, but I'm not really on board with the Tsutomu idea because I am uncomfortable with the 7 year time gap between 10ya coma start and the 17ya case when Tsutomu disappeared. If there was evidence that Tsutomu survived the BO for many years or had a connection that would explain how realHyoue and Tsutomu would cross each other, I'd feel more comfortable with it.

Rumi - Asaka (On top of being Amanda's bodyguard, she had a personal connection to Koji (I think that it's more likely that they were lovers rather than family members, though)—she witnessed the double-murder, escaped, and, now, is out for revenge against Rum—she's now testing Shinichi/Conan to see if he can help her) [heck of an echo in here]

Kanenori - Amuro's boxing teacher who also taught him a thing or two about waitstaffing and cooking. I am inclined to think he is on the side of good, but I am uncomfortable really calling it because he needs a followup case.

Uploader - Rumi

Tsutomu - no opinion yet.

Muga - basically Akako's monster butler with a makeover. Plot useless except for romantic comedies with Heiji.

Asaka - Rumi

Rum - Chikara because of course it's gonna be the final shogi showdown of ultimate destiny between Kohji's protege and his killer, getting the Akai family some vengeance.

Not that into the idea of Rumi loving Kohji though. I don't know why its so personal beyond she's pissed someone killed her charge and Kohji, but I'm in wait and see mode for that.

I agree that the 7 year gap is a pretty big issue—it's yet another case of too little info currently available to us—and I also agree that another person could've replaced the real Hyoue. Still, if the real Hyoue's been replaced, where is the real Hyoue? Still in a coma, elsewhere?

Yeah, for Kanenori, I might change my opinion from him being a high-ranking BO member to him being someone who just has a personal connection to Rei/Toru, depending on what we get from him in the next case he's in. I'm unsure about him, too, because I just don't know which mislead Gosho's gonna go with—is Gosho trying for a mislead, in terms of a BO member's identity (Kanenori turning out to be a BO member, but not Rum), or an alignment mislead (Kanenori turning out to be neither Rum nor a BO member)?

I'm unsure about Muga, too—I'm still wondering if he and Momiji have a role to play beyond interfering with HeijixKazuha. I think it'd be a waste for Gosho to have them play only that role—just as much of a waste as him ultimately having Sakurako play no role in the plot. 

As for me thinking Rumi is Koji's girlfriend rather than his sister—there's no reason a sister wouldn't be more or less driven over a sibling's death (as far as Rumi has clearly been driven) than a girlfriend would be over a lover's death. I guess some would say that my guess is, in fact, another example of the incorrect perception that romantic love has more of an impact than familial love. So maybe I should leave whether she's his girlfriend or sister alone until we actually get exposition/flashback from Rumi that answers that question directly.
