This is a theory that I thought up and want to share with you.
I warn in advance, if someone is not in sync with manga it will contain spoilers.
I can't help but think that Gosho will not end it with that, so it took me some time to finish a draft of a theory. With your help I hope to make it a complete
I thought he was the original boss for a while now, However I have a theory about who the boss is now.
I want you to recall this points:
*In the clash between Conan and Vermouth(Sharon) we learned that she doesn't age and she is both Chris and Sharon (Sharon is said to be dead).
*In the golden apple case Sharon has told Yukiko that she hate her daughter because she saw her looking like her husband in front of his grave (after she learned to do disguises).
*Sharon hide her anti-aging from the BO.
*Sharon is "the boss's ...."
My theory is that Karsuma was Sharon husband.
I thought it after thinking about why would this story about Chris appear in front the grave be meaningful.
I thought that it might be true and that now her daughter (real Chris) is disguise as Karasuma, while the mother-Sharon is acting as Chris after taking the original drag.
It might explain why Sharon has the luxury to do as she please, after all she does a lot of things her way.
Also she is looking for someone that will be "silver bullet" (what we can take as someone to destroy that BO). So maybe she tried to make Chris stop being the boss or something and failed so now she want someone from outside to make the BO(or her daughter) stop.
Moreover maybe because Chris(real) is actually the boss and Sharon is acting as Chris, Sharon must hide her anti ageing from the BO in order to hide from them that the real Chris is actually in disguise as the boss(and the real boss is dead).
What do you think about this theory?
