The selected eight
The assembly hall was split into two equal half's, with all the first year students standing on the left of the stage, and the second year students standing right of the stage. The fact that all the students in the school were told to gather together, and not just a single year told them it would be a big event.
Then the two section on each side would be further split up, they were grouped by each homeroom class which contained about fifty students. Quinn and Vorden were standing relatively close to each other while Peter was standing a row in front of them so they could keep an eye on him. While the girls stood directly at the front of the class.
