Demons
The motel room is silent, dark apart from the squares of light painted onto the ceiling by the lantern in the parking lot. You don't know why, but you can't sleep. A moment later you are glad you're awake because if you had been asleep, the scream from Sam's bed would probably have given you a heart attack. Instead, you stand and shake your brothers' shoulder until he wakes up. For a moment you think you see the afterglow of Hell glinting in his wide, panicked eyes, but it's just a reflection, easily dispelled. You wish his demons were, too
