Thank you for summing up your argument. I've read through it and now I think I appreciate the reason 1. I'll give up the Vermouth became younger theory and support the Vermouth stopped aging theory. So it follows that it had been decided that Vermouth has to change her identity when she stopped aging and Chris also has to switch her cover to her daughter or someone when she reached to around 50 like Sharon, right? And so she cannot live her life as one person... Oh that's pitty. She must be angry with the Dr. Miyano's research. I like it. That makes sense.
But I disagree to the reason 2. I still doubt the FBI was involved in her switching. You mean it's not the reason she's decided to change her identity but just increased the need to do so right? But I even doubt the possibility for the following reasons.
My previous posts were rather ambiguous so I'll be more specific in my argument this time . The theory that the FBI's investigation increased her switching need, it entailes that 1)Vermouth was aware of the possibility that2)the FBI has identifed some of her crimes as her doing before her switching. I doubt this in two ways.
First, I'll discuss the part 1)Vermouth was aware of the possibility that the FBI has identified some of her crimes as her doing before her switching. The reason that I find this unlikely is because she didn't extinguish Sharon before she switched to Chris. If Vermouth as Sharon had already noticed that her crimes were revealed by the FBI she firstly should think of faking Sharon's death since there is a possibility that sharon might be arrested by the FBI, which threatens her life and also might result in the BO's existance being exposed to the public. How could she be that easygoing not to fake Sharon's death when she's aware of the possibility. You said
"It might not have been convenient to the BO for Vermouth to lose her ability to move in high society. " but it seems like that's not inconvenient to the BO because Vermouth as Chris is actually taking a rest now from her cover life. In Pisco's case when she said "I wanna rest for a while. I'll stay in Japan. There are some things that I need to take care of." Gin and Vodka didn't stop it. It seems like her acting life is not a order from the BO but she's doing it on her own decidson making.
Well, I assumed "Sharon" when I said "she".
I agree to the idea that Vermouth's double duty period was to make a separate identity for Chris since it's suspicious if one person disappreared and then someone new appears but I doubt that this is to make it harder for the FBI to reveal her switching.
Second, I'll discuss the part 2)Vermouth was aware of the possibility that the FBI has identified some of her crimes as her doing before her switching. As for her crime 20 years ago, the FBI(Jodie) first laid an eye on Vermouth as Chris when Jodie heard Vermouth's cathing phrase" A secret makes a woman woman." and considering the age contradiction they connected Chris to her mother Sharon Vinyard and confirmed that the crime 20 years ago was actually Sharon's doing. So that was after Vermouth switched to Chris and has nothing to do with her switching. And it's unlikely that the FBI had already suspected Sharon for the crime 20 years ago since if that's the case it follows that Vermouth as Sharon had already been arrested. I don't know what is required specifically to issue an arrest warrent but it seems like fingerprint matching is enough to do that. In Halloween Party case Jodie said "That's how I finally found the proof that could explain the mysterious fact(age contradiction) that prevented your arrest." So fingerprint macthing can enable the FBI to issue an arrest warrent. Unlike Chris, Sharon is not too young to have commited a crime 20 years ago and Jodie has a fingerprint on her father's glassees as a proof. Thus I doubt the part 2)the FBI has identified some of her crimes as her doing before her switching And regarding her other crimes, even if the FBI don't have a proof(needed to issue an arrest warrent) to identify some past crimes as Sharon's doing the BO wouldn't allow her to keep Sharon identity if she was already in the process of being arrested. I thought it's their way to erase whoever could threatens the BO's existance.
I agree to the Vermouth stopped aging theory but I doubt which happeded 50 years ago in two ways.
Firstly the above theory entails that "Sharon" hadn't existed but I find that weird.
My point was a background as one's history and not a background as one's speciality when I said "it's weird that a star appears out of nowhere". Kir could use a resume to assure her background as Mizunashi Rena, who also hadn't existed. So it doesn't matter if "Mizunashi Rena" hadn't existed. Also the resume was revealed to be a cleverly disguised one later according to the FBI. So bacically the BO couldn't actually create one's background but they could just think of a good tricking way. On the other hand I think there's no resume in an entertaiment world. Suddenly a person appears in the world and make a debut on screen...? How could have she done that? That's where I have a question. What I feel weird is the phenomenon itself. I mean one should have some career before that. Seeing the way Sharon was speaking about her debut in a NY case I think Sharon's part on screen debut was not a tiny like without a line but rather big, at least memorable one, if not a lead part.
Also I think she wasn't lying when she said " My parents died on the day I debued, for which I'd had a tough time." After all I doubt that someone can make a screen debut without any training in advance. For me a TV personality job seems just ordinary and anyone could do the job such as interviewing a person and reading a script before a camera, which doesn't need a talent or skill.
You might have felt the surplus in this argument. This is where my conviction is. Sharon once said that "if there is such an existance as god shouldn't all honest hard working people be happy?" This is terriblly beside the point if we assume the speaker is a criminal. She should be killing a lot who are honest and working hard like Jodie's father. So I'm guessing that she was expressing herself when she was saying this line. Vermouth should have been honest and working hard before she joined the BO and I think that this line reffers to the period when she was getting an acting training before her debut on screen.
Secondly the theory includes Sharon's mom is Vermouth but if that's the case the time frame doesn't make sense.
I think differently. The BO's project seems to have begun over 50 years ago but if that's something to do with the Vermouth stopped aging then that doesn't make sense. Vermouth as Sharon's mom must have been around 30 when she drank some medicine and stopped aging because she's now around that age. The manga says Chris Vinyard age 29 so whatever your perception tells you Vermouth is now 29 years old in this series' setting. But it takes 5 - 10 years(I think at least 10 years) for an adult to notice that one isn't aging at all. So when she and the BO realised that she isn't aging Vermouth must have been around 35 - 40 as Sharon's mom. And then the project had started but I think Vermouth kept Sharon's mom identity until she reached to around 50 since Vermouth kept Sharon's identity until that age, which I think means it is around 50 that makeup for disguising will be harder. So it was after 10 - 15 years after the project had started that Vermouth switched her cover to Sharon. And then how old did Vermouth set Sharon as for her age? She is around 30 but it doesn't matter if she set herself her late 20's, that could expand the period of being Sharon and hence save her swithing times. So let's just say that Vermouth created Sharon at the age of 25. Then there's more than 40 - 35 years left until the current timeline. And if we add the period to the age 25 it entails that sharon must be over 60 - 65 years old in the current timeline. However Sharon is around 50 and thus [the BO project and Vermouth noticed her aging stop at the same time theory] doesn't make sense. I think Sharon is under 60.
I thought I proved the timing is also a fact. If that was not clear enough I'll be more specific in this.
Sharon:"Can you believe it? My daughter was standing in front of my husband's grave disguised as him.
Yukiko:"Ah if I recall you were sayng that your daughter beged you to give her a disguising lesson.
Sharon: "I haven't met her since then. It's been about 10 years..."
If it's only Sharon's word it could be a lie but this time her words are assured by Yukiko. If Sharon's word "it's been about 10 years" was a lie then Yukiko would question on this. It doesn't make sense if she says she's been out of contact with her daughter for 10 years when she had contact with her and told her friend about it within 10 years.
