Why we shouldn't lynch Coffee today
If Coffee is town:
* On nights when I can use my ability, I'm protected.
* Solaris can redirect all targeting abilities on rob to me, protecting rob.
* Coffee can target Solaris
At some point, mafia has to decide if they want to break this protective chain and use a NK on Coffee, saving us the lynch. If NK ever fails to go through as a result of this protective chain, we have a nearly-confirmed town in Coffee.
If Coffee is scum:
We still do the above, but at some point mafia has to decide to either waste a NK (highly unlikely) or give away Coffee as scum by breaking the chain.
If we lynch Coffee now and he flips town, we lost a protective role. If he flips scum - great. But there's still value in having a scum protective role trying to maintain his cover. The longer he survives the scummier he will look. Let's wait it out and see how things play out.
