Psychopath Ghost.

All the nurses felt scared and/or worried by Ghost's rowdy behavior; Ghost was kicking the door and screaming.
But he was only throwing a tantrum so that she would go brush his teeth.
You went to his rehabilitation room and told him
-If you want me to come in, you have to calm down first.- I tell him, as he already knows.
-I'm calm now.- Ghost said, peeking through the window.
