The Godfather, Part 2 [Concluded]

[Xiahou]

Xiahou: there's been only one time of us voting and then unvoting for each other, and that was because Don used a random voting thing, which got him votes from other people who he didn't select.

Even with the vote exchange withstanding, Don is most likely mafia. He sent the PM as a clear attempt to gain a defender in lynch votes and when that didn't pan out he's now using the PM to frame up one of his main accusers(me).

edit: I suppose, following the PM saga, that Proletariat can't be entirely ruled out either...
