My thoughts are...
while this is really thin reasoning (and this is coming from someone who's tried to make a case with even less), I think Zubz' behavior so far is weird and at best, anti-town.
The first thing Zubz does is come into the game without even reading his role. The problem here is that town benefits from any information it has; if you have none, then you don't know how to act. What's more, even if he had read it and pretended to not have, that is a pretty significant act of misdirection just to try to get us to talk about something. More importantly, there was a shift when people reacted negatively to "I have a secret~" and Zubz trying to dangle what is probably non-existent information in front of us. He said he'd reveal what it is if he survived, but he hasn't said anything. Frankly, I don't even want to know what the information is, because this whole thing smells like Zubz was too hot out the gate and it backfired, now he's just trying to cover his ass as best as he can. It's pure self-preservation, and he's trying to coat it in "not hurting town" so we don't badger him.
