I never really adapted to Gin,I like Vermouth better :p

**SPOILERS. I WARNED YOU SO, READ AT YOUR OWN RISK**
Definitly Vermouth. Even though she's part of the Black Organization, she keeps Shinichi/Conan's secret and actually (in my opinion), she doesn't seem that bad. Although, I do wonder WHY she's keeping the secret. I know that Shinichi saved her life back in New York, so I can understand her saving his ass once (maybe twice), but I think there's more than just oweing him for one. (This is just my opinion) :P
