I was wondering why the deciding vote of Advocate Vervolki was cast against Tox; perhaps it was because both of her companions were the only candidates for execution. In her place, anyone would have preferred to execute Tox in that situation.
And to withdraw the vote at the last moment? With a live serial killer and a commissioner present? To sabotage the execution and then, in the worst case, both of them end up dead at night? Don't make me laugh.
Anyway, Zubr is the one who raises the most suspicion, so I suggest he reveal his role and the results of his actions. He claims to be a town role, and if there are no more of that role, that's fine; we move on.
