He pursues Guest relentlessly. When the lights are on, he runs away instead, but when the lights go out, he chases Guest. If you fail to evade him... there is no telling what will happen to you. When he chases you, hide in the closet. If you hide too obviously, you will be caught, so hide the moment you hear footsteps. Occasionally he might let it slide if you're found, but there are no second chances. He cannot speak, nor can he communicate through writing.
