By this post and action, are you saying that you don't think Hi IQ is mafia?
I agree that DD seems "different", but tying it up only forces action IF someone does move. Otherwise it results in no lynch and effectively protects IQ.
At this point No I don't think Hi is mafia. They thought the same thing I've been thinking about all day at work.
It does no good for mafia to want to lynch a UD on night 1. By lynching an innocent UD they lose an innocent.
If you keep a definite UD alive they can get 2 innocents night 1 and 3 innocents night 2
If you lynch a definite UD night 1 then they still get 2 night 1 but only 2 night 2.
It goes from 5 innocents to 4 innocents by lynching the UD night 1.
