I'm trying to read through the thread to ascertain where the whole "cultists killing Blarg will lead to a double night kill" rumor/theory/speculation started. Was it Matt Attack? I can't seem to pin it down.
As for the Blarg vs Coppa vs Matt Attack thing...here are my thoughts
1. I don't think Matt Attack is a cultist. Sure, he's got information on Blarg, but that doesn't mean he's not town-sided. It just means he has information and he's been holding it close to his chest. I don't see anything in his playstyle that would point to him being cult. Possibly neutral.
2. Blarg is neutral, he even admitted as such. He could be hiding a something about his role easily. Everything we know about him comes from himself or Matt Attack, two people we are admitting we can't trust since we are considering lynching them. Lynching Blarg today will at least give us a lot of information and finally eliminate the unknown quantity that is Blargonaut from this game. Plus, we could have a kill free night.
3. Coppa does seem suspicious, and is probably our best option if we want to try and go for a cultist. I'm OK with going for Coppa, but tonight I still feel like Blarg is the better candidate. However, if someone has some really, really concreted stuff as to why coppa is cult, I say we go for it.
As it stands, its between Blarg and Coppa for me, and, as I said before, Blarg still is the better choice, at least for me.
