If that's the case, then it would make sense that both Town and Mafia would have defenses against thieves.
I'm trying to think of a way to build on this aside from "iLikeToSnipe is likely telling the truth," but I'm drawing a blank.
In any case, maybe keeping an eye on the Infinity Stones isn't a bad idea. If we can keep them spread out amongst town, we can counter anyone with a collection ability. Of course, that's only if something happens to FRAYDO and/or someone other than Irish turns out to be a thief.
