[Death by Mirrors]

Not attempting to move any more people around before I've had a good night's sleep, lest I goof a second time. But mdom, you stand at the place you stood when you could go straight (to the scream) and right (to the alien; who would normally have chased you out of the maze but I gave you a 50/50 chance to succeed on the encounter to make up for offering you a "left" when it should have been "right")

Except now you're facing north, whereas when you approached that place from another direction, you were facing east. In conclusion right is where you heard the scream.
