Corrected entry: Samantha supposedly is trying to leave clues and such so that Tom will find out what really happened to her. But in the scene where his wife, Maggie goes in the basement to light the water heater, Samantha turns the light out. Why exactly? This wasn't a clue for anything, and the least it did was cause Maggie to smack her head on the wall. Also, Tom goes down there later and simply turns the light back on, so what exactly was her reason for turning the light off in the first place? Boredom?
