Мафия 108. Haunted asylum

By the way, am I correct in understanding that the girl only blocks actions that were performed on the same night as her ultimate ability? Meaning, we might have clues tomorrow?

That's correct. In the next night, we won't have blocks or a kill from the person who killed in this night's Mafia game. If we believe Yashchur, it was a physical attack by the guard.
