Who do you think the SK shot, Galzria?
Pfft - Heck if I know. - but I'll dig my hole even deeper for you:
D1 Faust bread crumbed that he was going to track me. Every time my lynch was brought up Faust talked about "Galz can be put off until a future day". I didn't piece it together until after he flipped Tracker D2, but if scum (Mafia or SK) were looking for PR tells that likely led them to Faust. I'm not sure what led to the other scum to choosing Mcmc though, unless they were simply afraid of his reads.
On N2, there are a number of ways that a kill could be prevented:
Mafia shoots SK: This would mean the SK shot 2.718
Mafia Roleblocks SK: This would mean Mafia shot 2.718
Mafia Rolestopper protects a player: This would mean Mafia shot 2.718
Mafia or SK shoot a protected player: We have a 1-shot BulletProofer who targeted N1
Mafia and SK both target 2.718
SK shoots Hidden Commuter: This would mean Mafia shot 2.718.
Most of these point towards 2.718 being the Mafia kill, and actually, only two point towards Mafia knowing the identity of the SK (Mafia shoots SK last night, SK shoots 2.718 /// Mafia Roleblock SK last night and shoot 2.718). So there's a chance that Mafia do not. in fact, know the SK's identity.
