Essentially, I noticed Zhao's roleclaim early on and asked him about it, he gave a very poor justification and ultimately claimed Jester. This led everyone to prevent a would-be lynch to turn into a flip-flopped waiting game. Essentially, when Zhao claimed to win the game if he was majority lynched (causing the game to end), we panicked. We decided to avoid a majority lynch and instead wait it out.

Diao Chan (God bless her) had a role that allowed her to sacrifice herself to kill another. She asked if she could use it to kill Zhao so the Jester-wins-by-lynching rule would be negated. I said yes.

In the end, Zhao was Mafia, like I had originally thought and we have little time for a decision.
