Ok, I feel like me doing any further interrogating is pointless since the game is up on my intentions.
I have contacted every player and questioned them pointedly on the nature of the title of their roles as you will have experienced me do to yourselves.
I will not reveal who said what at least at this stage.
I can reveal that there are three categories of players, evil, civilian and good.
My hypothesis rests on the theme of the game -> which from the role names I have heard is James Bond.
Now this may come as a shock, but we, the staff (made up of evil characters and civilian/generic employees), are the villains and this bunker is our secret base. Infiltrating into our bunker are several good 'heros' , James Bond and co who are trying to stop our plan to take over the world.
Now if this is valid it gives me some idea of who may or may not be staff and infiltrators respectively.
I put forward the names @LyskTrevise, @The_Sane and @Ovog for consideration as infiltrators on this basis.
@Nafen did not reveal a side and I appreciate that some of the categorisation may have been a little woolly.
If I go with this plan then I am trusting @hollifer as I believe the seductress is an evil and hence staff role.
Everyone, please discuss.
