In the end, he wasn't. By accident or by design, who knows? Maybe they thought it was inevitable and didn't want to risk uncovering themselves further.
It's so hard to narrow down suspects with so many people. And it's also much harder playing as a C because you have to defend yourself while looking for the Gs.
Sounds like it would be a smart move by them you mean. I am half tempted to lynch him (Deneb) after yesterday just to confirm some of my suspicions. If it turns out he is in fact a C (which he might be), I am using utilitarian principles to justify my actions. One C to save all the rest of Cs is a small price to pay.
SAB
We won't get anywhere by just going back and forth. If we lynch SAB, and she turns out to be a G, I have a pretty clear idea of who to move on next.
