Vote: Nabe
There's no discernible pattern regarding the '?' so it's likely the double vote ability of a player. I doubt it's the case, but there's also some possibility it's an invisible player. Nabe, Strongbad, and Werekill all expressed interest in the game but didn't officially join. I want to test if one of them can appear in the vote count.
As for who to lynch today, I'd like for either Theo or Ruy. We have to lynch Theo at some point and I'd rather it be when we have some leeway than during crunch time. The longer he is in the game, the more problematic he becomes because each active individual has more influence over the game as it goes on. There are two reasons for this: First, role actions are more efficacious as player count decreases, mainly because targetability becomes more precise. The most salient example is kills (vig, nk). As the game goes on, the killer is able to more precisely hit someone that would be beneficial to them. Additionally the fewer players there are, the more influence a kill has over a game. It's dangerous to keep Theo around until later in the game because not only may he have is own abilities, but we will have to choose between lynching him and another player, guaranteeing that at least one scum player (Theo or other) survives to use an action. Secondly, individual voting power also increases as player count decreases. Since Theo's votes aren't necessarily town-aligned, it's risky to have him alive late game.
One last thing to say about Theo, I suspect from his "betting" comment that he is a marker or gambler who wins if he either guesses correctly who is alive at the end of the game or predicts a certain number of lynches correctly. From my experience with markers, if they win, their victory supersedes all other factions.
Regarding Ryu, I think that his reasoning for scumreading Z25 is poor. Z25's explanation was satisfying but Ruy is still pushing it. I'm also suspicious of the fact that Ryu has no interest in Theo. In past games, Ryu has been gung-ho about lynching indies as soon as possible. Theo flat out claimed 3P and Ruy hasn't reacted to it.
