I've really been thinking but I can't for the life of me figure out what Minish's role could be (not that I would say it out loud even if I did), so I have no clue as to how she can be so sure of whatever she's sure of. But I really want to survive just one more day and if Minish is Town there's probably a pretty good chance she's right with her suspicion. Seeing as I know that I'm Town, that would mean there's possibly a decent chance All Might isn't.
Vote: All Might
To reiterate I vote this way because I don't want my last night action to go to waste and because I'm choosing to trust Minish's theory for now.
