Well, the reason why I deliberated and removed my lynch was because AliB tends to inadvertently incriminate himself as a townie, so I had that in mind.
Obviously, in a fully fledged game I would never make a lynch this early/with this amount discussion. However since time is running out, taking into account the fact that AliB decided to leave me one vote from the hammer with a sudden changing of lynch added to the fact that he frequently changes his lynches in general and him seeming quite willing to confirm me as town:
Lynch: AliB
If zwarrior turns out as Mafia I'd question why he didn't just grab the opportunity to hammer and win the game instantly instead of dragging the game on further. What's the point of doing that when victory is within arms reach? If he's Mafia then he clearly didn't want to win the game at that point, why else.
Perfect Squared seems more town to me but only on the basis of comparing him to AliB, since there is only one Mafia Goon in play.
I'd say one of either PS or AliB is most probably Mafia. Just by chance and not reads I could easily vote for PS as I could for AliB.
