Soriku, you shouldn't need to tell me who it is. Well, you can't unless you post in the thread. The way this works is that I'll investigate you, and you'll switch with someone. Then, during the next day, you'll say who you switched with, and I'll share the results of my investigation. That is the genius of Khuutra's plan.
Granted, we're counting on the mafia not targeting you because you might switch with one of them, and they can't really afford to lose one of their guys, and we're counting on them not going after me on the assumption that the doctor will be protecting me. I'd assume that they'll target someone else in hopes of killing the doctor.
