I'll do the setup analysis again. this has been done already, but it's better if I go through it myself
1. Detective, 1-shot Commuter, Goon Cop; 1-shot Investigation Immune + Serial Killer
2. Watcher, Jailkeeper, Psychologist; 2-shot JOAT
3. 1-shot BP Townie, Jailkeeper, Bodyguard; Traitor Knows Mafia
4. 1-shot BP Commuter, Psychologist, Detective; Mafia Knows Traitor
5. Watcher, 1-shot BP Townie, 1-shot BP Commuter; 2-shot JOAT
6. Detective, Jailkeeper, Psychologist; Mafia Knows Traitor + Serial Killer
7. 1-shot Commuter, Jailkeeper, Detective; Traitor Knows Mafia + Serial Killer
8. Goon Cop, Psychologist, Bodyguard; 1-shot Investigation Immune
crossed all that don't have JK. These 4 were possible from Day1 on based on my role alone
2. Watcher, Jailkeeper, Psychologist; 2-shot JOAT
3. 1-shot BP Townie, Jailkeeper, Bodyguard; Traitor Knows Mafia
6. Detective, Jailkeeper, Psychologist; Mafia Knows Traitor + Serial Killer
7. 1-shot Commuter, Jailkeeper, Detective; Traitor Knows Mafia + Serial Killer
crossed 2 because there is no way that watcher doesn't claim. town!watcher just has zero reason not to claim. Same goes for 3 with 1-shot BP, so cross 3
6. Detective, Jailkeeper, Psychologist; Mafia Knows Traitor + Serial Killer
7. 1-shot Commuter, Jailkeeper, Detective; Traitor Knows Mafia + Serial Killer
so, we really have a SK. I thought this was extremely unlikely. like, a few percent or something. in james bond mafia, I knew voltaire was lying, because his claim could only be true in a scenario with 0 randomed T's, which was less than 1%. This is similar. One one-kill night - okay, but a 0-kill night AND a 1-kill night? well, it happened. This is like the first time there's a real reason to mistrust me, and now you're starting to believe me. I don't get it. If I were you, I'd kill me based on the fact that me lying is the only scenario without a SK.
But alas, these two setups are akin to Ichi/Jimmm lying. So, one of them is scum, most likely the traitor. At least this doesn't change the fact that Eevee is most likely the non-traitor scum.
