Mafia 101. Disputed Island

And yes, Sesama, I would still like to see an answer to my question :)

Okay, let's talk about it.
According to you, Dag is Mafia. Then there's no point in lynching him today. Perhaps tomorrow he will cause a lot of trouble for both Mafias with his Date.
Snowman. There's nothing on him. No evidence, no revealed roles. On what basis should he be lynched? And psychologically, he's not a Townie. Although he could be a Zero. Theoretically, psychologically.
I won't be lynching myself. Firstly, I'm not a Shaman to be into self-lynching, and secondly, I'm not Mafia. There's also a third reason, but the first two are enough.
That leaves Alex. There's evidence against him, and he's been inactive.
Therefore, from your list, I choose to lynch Alex.

Based on his behavior, and it's been noticeable since the very beginning. Plus, there's evidence.

You haven't played with me enough to judge me based on my behavior :)

Wow... So it turns out I infected myself...

That's why I don't like solving clues :(
