I'm guessing that Ibby is legit based on her nabbing of Raj as the SK. So I think things are between PJ and myself.
Since I know I'm innocent, and that Ibby likely investigated PJ already (hence her turn-around regarding him earlier in the game), I'm going to assume that she investigated me as innocent last night, and that we can conclude that the GF is investigation-immune.
So, either PJ is scum, or I'm scum.
First, the issue of PJ's role and his resulting guilt or innocence.
While I'm perfectly willing to accept that PJ did indeed search out and find CoolBot, becoming masons with him. I'm also willing to accept that his interaction with Lacey is as he says it is. I had figured something similar when PJ mentioned voteblocking the other day. However, that doesn't mean that PJ is a confirmed innocent. I've scoured the initial posts, and nowhere have I found any indication that masons are guaranteed-legitimate.
The timing of CoolBot's death also fits in very.... conveniently... with this revelation. Consider the fact that yesterday, for a massclaim, we knew there Ibby was a cop and that there would be a doc, most likely, who would be accepted as being innocent. With five players left, that leaves three claims to be had. Suppose Beaker been killed instead of CoolBot. CB and PJ could claim masons, but when the question of "guaranteed innocence" came up, we don't know what that answer would have been. It seems to me that PJ had to shut up his mason-mate in order to protect the notion of "guaranteed innocence of masons."
Consider also Night Three. That's the night in which nobody died. We know from Pwnz that he protected me that night. As I said, there are two scenarios that come from such facts. Either Raj and the Mafia GF both targeted me, or Raj targeted me, and the Mafia GF (be it me or someone else) chose to No-Kill.
The former scenario is pretty self-explanatory. SK and scum made their choices. The latter scenario means that the GF must've had a reason to No-Kill. To set up a WIFOM situation? A possibility. However, to set up a WIFOM like that would take several assumptions and/or risks that, quite frankly, I cannot believe any reasonable player would take.
To explain myself, I'll pose the hypothetical situation in which I am the GF and elected to No-Kill. In such a scenario, I could be cleared if in fact the Doctor were to protect me. Lo and behold, that's exactly what happened! But is it feasable to assume that the doc would protect me of all people? Absolutely not.
I can't see any other feasable explanation as to why there would have been no deaths on Night Three.
