Regarding the 3 watchers situation, Mango and Nat will be resolved this day phase. I don't believe that there can be 3 watchers, even 2 seems less likely, but 3 just seems impossible.
Also, if Nat really flips Mafia, then we can confirm that some scum were on TAC's wagon last day phase. How many, we probably don't know. I'm also suspicious of Lanji who just voted himself at the end of the phase and didn't want to vote queen before because it would look like OMGUS.
I don't really know why a townie would not want to vote someone he's suspicious of if he's got reasons for it, just because it might look bad. It struck me as odd tbh.
