I think you are misunderstanding. Vermouth as Sharon knew she was being investigated for her past crimes by the FBI. By switching to Chris she has a clean record again. She knew perfectly well who Jodie was, but didn't know her past. In V42-9 on page 2, Vermouth says, "This is Japan. Let's follow its customs and speak in Japanese. The FBI's star investigator Jodie" . This doesn't make much sense and I don't see how it is relevant to the point I made. The argument I put forth was that the way Sharon appeared, her mother died in a fire on the day of her debut, is very similar to the way Chris appeared, Sharon died and Chris suddenly quit her secretive private lifestyle after that. Basically that would hint that Vermouth was Sharon's mom as well and is actually a lot older than 50. The reason Vermouth might have switched from Sharon's mom to Sharon could be because of investigative pressure or her disguise skills back then weren't as good (she hadn't learned from Toichi yet) and she needed to switch to someone with a more youthful face. You are misunderstanding Sharon's words. Basically she said that Chris had an easy time breaking in because Sharon was already an actress and had the connections. We also know from other character's commentary that Chris Vineyard is a superstar and very popular. She's not just a pretty face, she acts well too. Also, plenty of actors in real life break into acting without familial connections, so Sharon breaking in on her own power isn't that hard to imagine, especially since she is a Black Org agent and could very well have tapped the Black Org's power to help. Hidemi easily became a television personality and she had no prior background. The Org might have helped, but Sharon had the Org to help her too. APTX 4869 was only known to work as a poison and was called the incomplete detective because it didn't work as intended. Vermouth must have used something else because it doesn't make sense for her to try to commit suicide. There was extensive debate about the existence of Sharon's daughter at DCTP. After pages of debate and going back to the japanese, there was no evidence other than Sharon's word that she had a daughter who was a separate existence from her. Basically the reader is forced to take it on Akai, Jodie, and Conan's good word that they didn't botch their investigations. Yukiko's words in the NY case, if you look at a good translations, don't imply direct knowledge of Chris, only what she has heard through Sharon.
