Not to mention that during this game, the town didn't accomplish anything useful at all. So, here, you shouldn't be guided by likes and dislikes, but by reasoning. Anyone who has been paying attention has some assumptions about who Hosto is, and that's what makes Plesen look even more interesting, as he supposedly, after revealing himself as a checker, wanted to get Hosto killed. In the very first night, he was shocked, which eliminates half of the mafia roles he could possibly have.
Do you think he would have blocked Arandor if Arandor claimed to be a dog person? Or used his ultimate on a free player like Spir, or wasted his first ultimate for some completely unclear reason?
Executing Hosto now would be a big mistake. It's better to pay attention to other candidates, including the one who has been voting against everyone who turned out to be a townie for three days, without offering anything.
