Мафия 39. Piece of emptiness for the small December.

and if we're going there, a dog doesn't provide defense. it's a different story if Koshi had some kind of weapon/gun and supposedly left it at home

That's true, I don't see any other options - South and Bio have armor that provides defense, so you wouldn't forget about that.
Or maybe she's one of those with a weapon, but no defense... And "forgot it at home" indicates that she didn't use that weapon that night. North would have killed the attacker. Techcrazy? Mafia?))
