Yes, i totally agree with Detectiveshinichi, exactly the same thoughts of mine=) Most likely Okiya Subaru is actually Akai and the scar Akai is Bourbon. It's similar with Vermouth and Jodies case. Gosho made us think the other way round abt the character. So i am sure this time is d same scheme. Conan definitely knows abt Akai faked death and both of them might alrdy made up this scheme together back in the hospital. Conan knows abt Okiya is Akai, thts why he let Okiya stay at Shinichi place.
