Episode 1. Chapter 4.

Around lunch time Leonard met his English teacher and his father, who worked as a substitute for the music teacher, in the hallway.
Leonard talked to the English teacher about next week’s homework.
Then the teachers hurried away.

Leonard was surprised to see that the teachers weren’t walking towards the teacher’s lounge, like they usually did before and after lunch.
Then it hit him: some of the teachers were going to have a lunch meeting in a restaurant today - at the mall!
