I totally called that Lily Chen was mafia! Twice over, in fact. She was the investigator who revealed to Miranda, and look at the conversation Miranda and I had on day 1:
Me:
"I would like to request that you PLEASE don't give the medkit to someone who asks for it claiming to be investigator/that they know an investigator or something. Mafia (or more specifically and terribly, rogues) have gotten their hands on medkits the past two games in this way. Medkit, as nice as it is for keeping a townie alive, is really valuable due to its ability to catch a mafia. To maximize this, I say you should give it to an innocent child.
To accomplish this, I would recommend posting something similar to the above on forum, and then asking ONE innocent child to reveal to you. As soon as they do, you post that you have located an innocent child so we don't have more role leaking than there needs to be. Then, you should give the medkit to that innocent child ASAP."
Miranda:
"Thanks for the tip! Also, a certain person asked for the medkit, and claimed investigator when I said I'd rather give it to an innocent child. So you may have already been right."
Me:
"Keep suspicions of that person in the back of your mind then. I haven't actually seen real investigators be so forward in getting the medkit so far, although it's possible that one is this time. Probably be even more suspicious if that "investigator" isn't using you as their proxy (because why would an investigator be spilling their role like that?) or if the "investigator" is a newbie (because then how are they so on the ball about going after items?)
We of course don't want to risk lynching an investigator, but they should be higher on the prophet smite list."
So, I called that Miranda's investigator was sketchy. I was also super sketched out by both Miranda and Lily Chen, since they were both running for mayor. As of Day 2, when Isaac was smited, I knew that we were both innocent. So, I thought it was VERY unlikely that mafia didn't have anyone running for the elected roles, so I put it at very high likelihood that one of Miranda and Lily was mafia. Then Miranda dies, and suddenly I'm super suspicious of Lily. However, this isn't a suspicion I can use as fodder for a lynch mob though, because it's based off me knowing that I'm innocent and that Isaac was innocent, which was not something that could be objectively known.
I was so suspicious of Lily, in fact, that I sent this message to Isaac at one point:
"Lily wants to talk to me in private. I may be irrationally paranoid of her being mafia, but I may get conscripted. I guess you would have no way of knowing afterwards though. So I guess this is mainly to say "I called it!" if I do get conscripted."
Ironically, he would have had a way of knowing afterwards whether or not I was conscripted.
