Your so-called night investigation would be useless. We thought we had executed a serial killer (which was true) and would block the only Mafia member. That is, there shouldn't be any victims. The Witness (it's a pity I found this out too late) can only see the killer if they are watching the victim. Hence, on the third night, a night investigation by the Witness is completely unnecessary. I even forgot about my own night investigation until Hos knocked and asked me about it)))))
Lynx, think about something else. If Drag is Mafia, then Tox was the Commissioner. This means we should go back to voting for Vervolke. If I were Mafia, why would she first vote for me? Apparently, she thought I could be hanged, but then she saw that Tox was being hanged and changed her vote. Moreover, the Mafia has a better chance of accurately determining his role. So they determined it and realized that they need to hang him now. And they don't necessarily need to hang me - a night investigation won't do them any harm.

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
