File 622 being Okiya Introduction Case.
File 898 being the end of the Scarlet Showdown Case.
To me, the Bourbon Arc is the lowest point of the series:
- Okiya's allegiance and Scar Akai's allegiance was pretty much solved well before even Sera's introduction. Red Shirts Case solidified the allegiances of Scar Akai and Okiya even if we didn't know Bourbon's true face, or even if Scar Akai was Bourbon.
- Scar Akai appears in two cases before Amuro's introduction case, with nearly a 100-chapter gap.
- "Wedge of Steel" Kir does close to nothing, while Bourbon is able to run around and play Tennis with Conan, and has near freedom.
- There isn't a background case like with the Rum Arc (Haneda Kohji Case) or Kir Arc (Hondou Case/plot from 2 years ago)
- Mystery Train shows that Amuro was Scar Akai and Bourbon, and Okiya is Akai, and Sera is Akai's sister. This case would have been great if it served as one of the climax cases with the Bourbon Arc if the Pickpocket Case and Tea Case and Scarlet Showdown were grouped closer together similar to Clash of Red and Black. Because of this, the pacing of the arc is god awful.
Points of concern:
- Kir mentioned "Akai's sister" during the Hospital Case to Gin, so best case is Gosho had some idea of Akai's extended family, and worst case is he made a placeholder character for future use if he hadn't come up with Sera at that point of time.
- I'm going to presume the idea of a "female high school detective" was probably in the early stages of design during the Hospital Showdown Cases as the Female Detective from the High School Detective's Case proved to be popular.
- Okiya was always going to be Akai and not anyone else as Conan's Actions and Speech indicates that he was somebody he knew
My questions are as follows:
If Gosho was going to always have Bourbon be a spy, what is the logical reason/head canon as to why he's roaming around as Scar Akai? Or even why Gosho allowed this to happen? The actions of dressing up as Scar Akai are the actions of a loyal BO member, and not a spy. A spy working to take out the BO wouldn't be taking the risk of being killed by Gin/Chianti during the Red Shirts Case.
If Gosho was going to have Bourbon be a spy, why did Gosho have Akai willing to have Bourbon killed in at least one instance if not two. First being allowing Chianti to kill Scar Akai during the Red Shirts Case, and throwing a Grenade infront of his face during the Mystery Train.
During the Red Shirts case, Bourbon was stated he hates Akai the most.
The presumption during the Bourbon Arc was:
- Bourbon and Akai hate each other, or at least Bourbon hates Akai
- Mystery Train "hinted" at one reason for this being related to Akemi Miyano
- Bourbon started cosplaying as Akai to see if he was really dead by seeing FBI's reactions. Later dressed up to gauge Sera's reaction.
- Bourbon couldn't believe Akai would be killed during the Hospital Arc since he can only kill Akai himself
- Bourbon was skilled Detective as stated by Kir during Okiya's Intro Case
- Gin cancelled the kill order because Vermouth told him something, which was likely something to the effect of: "Bourbon dressed up as Akai to see if the FBI really thinks he's dead". Why Bourbon didn't tell the rest of the BO this, I don't really understand even given the knowledge that he's "Secretive" and with everything up to and including the Red Shirts case.
I'm highly convinced that Gosho reworked the Bourbon Arc's plot and characters after the Red Shirts Case up and to the London Case, or after the Mystery Train Arc.
As a main example:
Vermouth wanted Sherry dead during the Mystery Train Arc by blowing up the Train. Gin wanted Sherry dead and was going to blow up the Train Station upon the train arrival. Why would a spy allow Sherry to return to or get captured by the organisation? If not that, killed. He was the one who found the video of Sherry and told Vermouth and the BO.
Bourbon should have known Sherry was going to be dead for betraying the org the second he leaked that information. Given this information, if _SPY_Bourbon's police friends came to rescue Sherry after he realised Vermouth was determined to kill Sherry, how would he explain this to the BO?
The only real "foreshadowing" of something relative of Bourbon being a Spy that I found pre-Mystery Train was of someone calling the Bomb Squad during the Red Shirts case. An officer hints at an informant regarding the bombs involved, and the second officer dismisses the information saying they just want to save themselves. To me, I believe Scar Akai made that call to the police force, since he was able to solve the case, and likely also figured out the bombs were fake. This dialogue between the officers can still be consistent if Scar Akai was or wasn't a spy -- the informant could have been a background character too. This doesn't exactly matter too much.
Now when Scotch became involved, a lot of Bourbon's characterisation is changed so the reader can be sympathetic towards him. This is likely due to both Amuro's popularity, and the Seiyuu's popularity in Japan.
