Мафия 53. X-men: The Return

Funny. To suddenly eliminate a random player (who might not even be a Mafia member), risking oneself and practically revealing one's true role. Gumer is such a Gumer. Or is this a clever move by the twins?) But still, I don't understand why.

Omega couldn't have been poisoning anyone; he had a block on all night actions.

I mean, during the second night. It's unlikely Omega was just sitting around. Although, he could still have been poisoning Toria, Morny, or Gur.

In principle, Mercury could have been infected if he was protecting his sister, and she was poisoned, as poisoning infects all protectors, except for the Angel and the Night Serpent, right?

But in that case, the sister would also have been infected, wouldn't she?
