Jhon goes to the staff room and notices that there are a group of guys and girls. The guy look exactly alike and have the same voice and talk about the same thing and this applies for the girls as well. Jhon gets terrified by this. No one is an individual. Jhon makes a speech and says Linda was a slave and others should be set free. Jhon decides to tell everyone if they like being slaves. Also says he came to set them free. They think he went mad and send him to the hospital. Jhon takes the Soma tablets and throws them. Benard acts like he is helping but he's really not. Police come and settle the situation.
