In the AV room, you can find a hidden Repair A on the teacher's desk. Go up the stairs. In the library, you can find a hidden Escape H in the last book shelf against the wall. Go through the back door of room 5A. Lan will sneak to his desk. Ms. Mari will introduce Mr. Higsby as an assistant for the class. Talk to all the classmates and the bell will then ring. Mr. Higsby will begin class since Ms. Mari is sick in the nurses office. A WWW re-education program will start playing. Talk to Dex and he will try to take on the viruses, but fail. Talk to Mayl and she will give you Roll R. Jack into the blackboard.
