The Bison, judging by his constant eagerness to eliminate someone, is Mafia.
Execute the Bison.
There's no need for the Mafia to eliminate anyone in this game. They don't kill anyone on their own; they only infect. In a few days, votes and special abilities simply won't affect them, and they'll win. Right now, the only thing they've done is during the second night, when a Scientist encountered one of them. THAT'S IT!
And you, Tox, didn't even describe the Night Doctor's action correctly.
7. Scientists search for each other/upon finding, they try to cure each other from the virus - they lie together in the grave.
11. The Monster kills/heals (healing is not displayed) - it went to kill the Rogue.
8. The Analyst checks the status - ???
Judging by the fact that they weren't in a hurry to execute Vistrita.
We must execute someone! If there's a No Night Vote, we won't be able to identify the infected.

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!
