I think both players are right.
Most likely, Zubr is one of the specialists. They went to Morning, checked him out, found out he's a zombie, and are trying to get rid of him.
But! Morning could very well be infected! They also have a zombie status!
And then the theory that Morning is an infected town member, whose night kill landed on mafia, is quite possible. We have no reason not to think so, right? There was no block on Morning.
So cancel the execution of Morning, execute Toriy.
Zubr, call your specialists and join us. If anything, the doctor will check Morning on the next night.
