While in a case like this I would normally go with what seems to be the best lead in a situation this dire, I'm gonna have to disagree about apart. Someone'll have to be the devil's advocate, after all. And if that puts suspicion on me...well. I was the one they voted for, after all.
This is a Beginner's Mafia, so there are some things that I expect certain people to do. Random voting is one, especially if they don't know that they can vote for no one. I'd not be surprised of apart didn't, especially considering they didn't vote on the day No-one received the most votes. Coupling this in with my thoughts that day, where I was briefly confused (before reading it) about whether we had to vote for someone or not because, since Darkest Dungeon was the only Mafia I'd ever really played and there attacking was obligatory (opting out came with a pretty hefty penalty).
I can't say that not voting is a particularly solid option, however. If day 3 was any indication, the vigilante has the potential to be as much of a detriment to us as the mafia. I'm going to assume that they realized that randomly voting for people wasn't the best choice, and that's why only one person died today- though I do find it fairly odd that they only did it on night 2 and didn't go for it the night before, considering killer really didn't do or say anything incriminating other than...ask a question. Point is, max, 2 people will die tonight. Assuming we kill somebody today, that's 3 over the course of an in-game 24 hours.
Speaking of killer, I thought his last words were cryptic and in reference to apart, but considering he was town I don't know if that's possible. Still standing by my assertion.
Ah, actually, this all reminds me. Lize, her role being known, is definitely in danger, and the vigilante's just about the only person who can save her assuming she's targeted. Well, them or votes. After all, considering she's the Fool, she's probably the most important piece we have. Especially as we dwindle in number. I won't recommend the vigilante using their ability on her in an attempt to block a kill, though. Certainly not if we vote someone today, the risk of the max toll being reached in that scenario is pretty high. But it is worth keeping in mind, as taking this into account, we could minimize the deaths today to either 1 (with the death of the vigilante only, at night) or 2 (with the death of 2 non-vigilantes, hopefully a mafia member being among them). The former scenario is semi-ideal (only in that there'd be minimal deaths- losing the vigilante could potentially be quite the hit to the town's speed and the endgame, plus no progress'd be made- so not exactly great), the latter has a hire chance of flubbing but is possible and would hopefully cripple the mafia, putting them in dire straits.
God I hope this is coherent, I've been writing this for the past hour at 2-3 in the morning. Work today's gonna be fuuuuun.
Well, assuming I'm not on by the time the day ends, I'll go [VOTE] No-One and edit it if something comes up or we decide on something.
