occasionally he will sprint into your room and you have to stay completely silent for a few seconds until he goes away due to his poor eyesight, if you make any sound he will kill you. his face could also appear in your camera with a small minigame you will have to complete (sort of like old man consequences). if you don't complete it in time or you mess up three times you will either lose 10 power or his aggression will be raised. overall i think he is a pretty elaborate character and it would be awesome for him to be in this
