In light of recent events, I'm less suspicious of ultron than I have been previously, but I could see myself voting for him today. The only thing sticking out in my mind is LoC listing him as very suspicious on Day One. As I said, he also soft-bussed Prodigy in the same post, and the question I'm asking myself is whether or not he would double up on that kind of gambit. This is a classic Wine In Front Of Me situation.
I'm also considering throwing a vote at Timeaisis. He and ultron have been a bit of a pair in my eyes since the game began, because their playstyles have been so similar: low conflict, commenting mostly on gameplay mechanics, and never taking too strong a stance on anybody but Blarg. I've long thought that one of them is likely a Cultist, but not both. And then we have LoC, who was also playing along those lines, but in a considerably more visible manner. Three people, all exhibiting the same shady behavior, and one of them is a confirmed Cultist. It almost seems too obvious, but it also feels like I'm talking myself out of a good bet.
