I've had the time to go back and skim through a couple finished games and I hadn't seen the 'lover duo' before where one dying automatically suicides the other, but I kinda like it in a demented sort of way.

So we have:
1) Poisoner, about to make a hit on unknown individual. (Pancakemix)
2) Victim of Poisoner, who did not get poisoned in any way... but maybe he picked up one of the leftover syringes? (I doubt it though. Mob makes a good point)
3) Killer, who killed the poisoner before the poisoner finished his action
and lastly,
4) Suicidal Lover, who kills herself after discovering her lover's dead body. (Deuceswild222)
Is it at all possible (this is directed at some of the more experienced Mafia players in this game) that the mafia was blocked tonight (I know we already lost one roleblocker, could there be two in a game this size?) and the individual who killed the poisoner is a watcher, or cop or something? I guess I'm wondering if there is a 'protecter' role, who, when seeing that Pancakemix was about to poison someone, was able to step in and kill Pancakemix instead. If there isn't a second roleblocker, than the first guess isn't even possible. And for the second theory, it would require a really good guess on that person's part to "watch" Pancakemix.
