The Town has at least one role guaranteed, and even if Charlie swapped items, I still don't see any combination that would only produce negative results. What's the point of the Villager panicking?

I just want to remind you that both Villager roles are mine. I thought long and hard about whether to lend one of them to Tox, but he didn't agree. So for now, they will be in the bank, behind an iron door, the code to which only I know. And besides me, only one other unnamed Villager has the right to possess one of them – and by the way, I wouldn't recommend that he get involved in this for now. Although he probably understands that himself.
Lochen, in your theory, I'm the Mafia member who initially tried to get close to you as a pair, right?
