Ok then.
First of all : faust's claim is very believable to me. On day 1, I noted to myself that faust's play reminded me of what he did in Paris Mafia. In that game... well the setup was complicated, but faust basically played in such a way that he would be suspected while not being lynched. It's a bit more complex than that, but basically he changed his play to avoid both nightkills and lynches because he was a very important PR. I felt that his less involved, less leading playstyle here fit that narrative.
Then there's the fact that I don't think it makes a ton of sense for him to claim a result like this as scum. Maybe he is a Mafia Ninja Tracker, but even then, if he was just claiming to save his life he would not claim a guity result, and if he was trying to frame WW... well that might go poorly for him in a bunch of different ways, very risky for no real reason. As I mentioned before, i'm fairly certain that his claim, real or not, was prepared beforehand.
