Khushrenada pretty much covers it. I slipped up in PMs with Sir_Stabbalot, and while trying to cover my role, I asked SS to show me his PM from TVman to prove he was a townie, while attempting to pose as normal townie, myself. He then noted that normal townies didn't get a message telling them they are townies, which, essentially meant that I had unveiled to him that I had some sort of role.
But yeah, basically, at that point, if SS had gone on what he had learned from us, his cover would have been blown. Then, at the end of day 2, it was two late. All but 18 Days, NuclearSpeed, Dasmos, oohhboy, and Sir_Stabbalot's roles had been revealed to Khush and I. Then Dasmos was voted out, leaving the other four. At this point, I checked oohhboy, and we found that he was mafia, while NuclearSpeed starting PMing me. Eventually, he claimed to be a townie, and knowing there was only one townie left without a verified role, while there were only two players claiming to be townies, we knew we had to go after one with the vote, while we got ShyGuy to go after the confirmed Brain. It was just out luck that 18 Days was a Brain, but 18 Days could have only been a Brain or a townie at that point, so letting him die from vote abstinence was fine by us, since it could kill a brain or it could kill the last townie, confirming who the brains were.
At this point, NS died, and Sir_Stabbalot became the only person who's story didn't line up, though we had been listening it to the longest. I think it's pretty obvious from this thread that SS has given up and is pretty guilty through the evidence, but I guess that's left to everyone else to decide.
Edit: Well, that's five people, over half the vote, voting for Stabby, including himself...
I'm also for ending the day.
