The Watcher has very stalkerish behavior. It appears at midnight each night, watching you sleep. It's... creepy. No one knows what its motives are. It doesn't fight. Will turn into moving black smoke once it notices you, and will leave in its black fog/black smoke form. It doesn't talk. At all. And the only time it does communicate is through single-worded messages on the walls or floor in some strange black substance. The substance behaves like blood. Viscous, but unknown if it's harmful.
