I'm talking about shapeshifters.
Now, random stuff with little relevance: Ideally we want to lynch a knife guy. This gives us the best chances. With one SS and one knife guy, they each have a chance of killing each other, which would be one less person we have to root out.
Scary thought I had: Remember how I mentioned ages back that SS might have some special ability other than killing, what with the seemingly horrible odds they had (Us having a ton of specials, there only being three of them)? Well, this is HUGELY unlikely, but maybe the people they attack went crazy.
Actual relevant and possibly important ponderings: No knife attacks on the first day. Either they get to attack every other day, or both were blocked. This would mean we have one SS, and the two knife guys are Frisian and Ruthven.
