Well, I guess that isn't
bad for the town. Being not innocent, he probably didn't factor into our win condition, but also he didn't add to the Mafia's win condition either.
I'm thinking some sort of third-party vig role? The mafia group I play with IRL every week often includes Serial Killer (must kill every night; win condition is to be one of the last players standing) as a pressure role on both the town and the mafia. And in a game this size, it would make sense to have two roles that are obligated to kill, so that it doesn't last forever. I would wager that in addition to the Mafia we also have a town-aligned Vigilante somewhere. Whoever you are, you'll be useful to us.
This theory would imply two things:
1 - The healer got lucky and blocked the Serial Killer (JackPK)'s killing attempt on who was statistically most likely to be a townie
2 - The Innocent Vigilante chose not to kill on the first night, which is reasonable, especially on this forum.
Other than that no third-party roles really come to mind, at least none that would go down in a single blow. Cannibal (like Serial Killer except dies if is unsuccessful at killing) is one we play with sometimes, but that still fits the mold we have here. Jester (wincon: get lynched) is not used much here, as Alien (bulletproof, wins if lynched after being shot once) lends itself better to asynchronous Mafia. There would be little point to an investigative or supportive third-party role, too, and also I'm just uncreative and unused to actually playing non-IRL mafia.
Also, take the flavor text into account. Knives were mentioned and if flavor is at all relevant here I'm willing to assume that they're a
Checkhov's Volcano. No other reason to mention them, really. And knives are hardly useful for much other than killing.
As a postscript, I am curious about the usage of the word rifle: It might just be selective attention on my part, but I have to wonder whether or not it was intentional priming.
