I just imagined this situation: Snowman is sitting there, thinking about who to recruit. And he thinks, "Hmm, how about I recruit Yashur! He's very cunning, just like me!"
So, 24 hours pass, and suddenly - Yashur is a zombie. And then he suggests to Snowman: "Let's block Kosh, so that later she can be hanged, and we'll act like we had nothing to do with it!" And Snowman is like: "Great idea! I like it!"
