Good to know

Beside: on one of the four squares directly above, below, left or right, in the same room. Diagonally does not count, and neither does through a wall. A window or door in the wall of your square is beside you.
Alone: nobody else in the same room, the victim included. Alone with someone: those two, and nobody else in that room.
