You find out that the inmate is known as Karl, and that he is delusional in that he believes that large Grays (aliens from another planet) can read and steal his thoughts. Karl tells the officers that he has been looking for a method to keep the Grays from getting his thoughts. The corrections officers told him that the foil is special antialien foil. They tell him that it is in the corrections officers hats as well, and it protects them from aliens reading their minds. You find out that the corrections officers have been entertaining themselves with Karl for the past year and a half. Nobody has made any attempt at getting Karl a mental health referral, and they have been encouraging his delusions for their amusement. Although it is not clear to you what the exact nature of Karls problem is, it is evident that he is the victim of declining mental health. In addition to the incident, it is clear that the other inmates locked in nearby cells are not happy with what the corrections officers are doing to Karl.
