I really do think IM2 is Sawneeks, not only because of posting style, but also because she's been exactly that way in the main game - a bit hedgy, and making a lot of noise over minute details. I haven't played with her in a long time, so I dunno if this is just her still getting her bearings as town... But she's not really solving, IMO.
I wouldn't vote there because of this phase, but I think I would vote there if I can more accurately tie IM2's behavior to Sawneeks' previous behavior in my head.
