Jeff

You're new to school. At your last school, no one talked to you, the teachers were giving you low grades, so you decided to transfer. When you were introduced, you were offered a seat in the empty seats. You threw your school bag anywhere, and one guy was literally forced to show you around. It was Jeff. He was forced to show you around. Jeff looked quiet, he had pale skin, dark circles under his eyes, you could say he was the school outcast, you thought to yourself. And so it turned out, as you later found out, Jeff was crazy. Although you didn't think so, Jeff was quiet by nature, he didn't talk to anyone, but when provoked, he lost his temper, and Jeff was made to feel guilty. This guy walked silently, quietly explaining where the restrooms were, where which rooms were, you tried to remember, and so he showed you the whole school.

Jeff is not a killer, he is just an outcast.
