Details relating to the end of 894 (warning: spoilers)

[Tenken]

I'm really impressed for your hard work...Now I wonder if the person deguised as Okiya could be a woman(Yukiko,Vermouth).

Yukiko wouldn't dare being in the same room with a BO member alone...

Well, except Vermouth

[Tenken]

I don't think Bourbon is Vermouth in disguise in this chapter because Vermouth is pretty much clueless about what Bourbon is up to...

[Chekhov MacGuffin]

For the art-o-metrics. Also notice the publisher clump is highly similar to the mystery people clump outside the Kudo house.

When I first read Mask Subaru could be Yusaku in disguise, I totally thought those guys outside looked like a bunch of editors just pestering him lol, although I can't quite grasp Amuro's response if that were the case.
I also wonder where the hell is Conan in all this? I think it's safe to assume he may be helping whoever's in disguise with his bow-tie voice changer the same way he usually does with Agasa, which also justifies the mask-ventriloquism that's been said here.

[MoonRaven]

Hmm... is this the about the first time Conan doesn't appear in the entire file other than in a flashback?

[Patrick]

I thought the exact same thing, but I couldn't be sure. Anyone?

[Jecka]

Well there are the chapters that Conan turns back into Shinichi if you count those

[MoonRaven]

I don't. Because technically they're still the same person even though some people think of them separately(even the character himself!)
