Its not easy for him to deal with you, even when he's the strictes caretaker at this station.

He comes into your room because you haven't come out for dinner, again. He holds your food tray. its really filled. He puts it down on your bed, where you're laying in, and he asks you, sounding annoyed. "why weren't you at dinner?"
