In the opening scenes as the camera draws back from the teacher reading, the second student, a boy, on the left is wearing a headgear with a blue neckstrap. Later in the scene, as students are leaving, he can be seen again briefly standing. In the following scene in the school hallway, as the teacher is taking with another teacher, the boy with the headgear walks past them and down the stairs.
Remark: Sorry, these are the best grabs we have.
