Aw man... This is hard... This is painful! It feels like I'm betraying a close friend, but... there's only one answer, and I have to go with it.
I'm sorry Webadict.
Please, let me explain my reasoning, from my perspective.
Day 1: I'm given the role of Kook by Meph. I'm unhappy with such a crap role, but I accept it.
Day 3: Beacon PM's me, certifying that he has checked me out and knows that I'm harmless. He tells me that on night 1, he checked Webadict, and got the result "kill".
Now, to gaurantee that we don't wrongly convict a AWV, I concoct a brilliant plan: I PM Webadict, telling him that I'm the detective, and that I checked him and got the result of "no role" which, according to the rules, a dopp would get, so I wanted him to convince me personally if he was a townie. If he went a long with the lie and claimed townie, then I'd know for a fact that he's lying and would be able to correctly convict him, HOWEVER, if he saw through my lie, then I'd know that he's either a:
1)AWV
or
2)exterminator
The result? Webadict saw through my lie, but because Beacon still didn't trust WA, we formed a town base by proxy through me. He confirmed himself as a AWV and we were happy. I never told WA of Beacon's identity.
However, there were a couple possibilities that dismissed, mainly that it's possible for the dopps to have a role character, thus rendering the detective ploy moot.
Also, I PM Zai to try to squeeze info out of him and hopefully make him subservient to the town base. I purposefully lied to Zai during day 3, making it seem as though the town base was much larger than it actually was. I never told Zai anyone's identity.
Day 4: Beacon dies, the town base is just me and WA now.
Day 5: Bob dies, and it's revealed that he's the AWV. I PM Meph to clarify the rules, and he says that there can only be one of each role. Webadict way lying through his teeth, and I have to take action.
So, in conclusion, everything else is impossible, WA cannot be a townie, he can only be an exterminator, a VERY clever dopp, or some combination thereof including roles and mindshields.
There is only one reasonable, guaranteed way of killing a killer, and that's voting Webadict.
