If the Cult was our only concern, then we would have won right away. It appears that we have a two ways to look at this.

1. There's another Cultist or two remaining. Be cautious!
2. The Cult is gone; the Mafia becomes our main threat.

I want to say that it's very likely that we have a Cult member remaining, but I don't think the remaining member is a real threat, so we should focus on finding the scums.
