Who said that i'm not trusting you? I didn't said that. Also i said that i'm not protecting Ali, do you think that i would really protect someone with only just one vote? I said that i didn't do that for protecting someone, but i only find it strange.
Cas, there are only two roles where they can roleblock someone: Drunk and Mason. As you said you didn't do your action on the first night and Nano said (assuming that he didn't lie) he was roleblocked, and with that we can delete already one of the two roles of this list. The role Mason only roleblock someone when that player is a cultist, but they aren't informed about that. This is why i found strange that you roleblocked Ali. I didn't say that you're a cultist by the way.
