It just bothers me that Vermouth could disguise herself as Dr. Araide for so long. Of course it is Vermouth and she can disguise perfectly, but what about all the medical knowledge that is necessary to perform such a long-time scheme?
Vermouth usually seems to impersonate someone for only a short time.
Spoiler:
If I recall correctly, she decided to impersonate Araide after she stole the file cases that were connected to Kogoro in some way. Surely there would have been candidates that would be easier to disguise as, that could also be used to investigate in the schools.
It would be plausible if she was a physician, biochemist or pharmacist herself. Ai proved that she can examine people (dead or alive) to a certain degree aswell.
Since we don't know how old Vermouth is, maybe she pursued such a career before her acting career. Maybe that's one of the reasons why she is so strongly connected to the Miyanos and their research. Or maybe she was a scientist before she entered the BO?
Thoughts, anyone? Or did I miss some explanation that was going on?
