Nigel

The school is filled with screams and sirens. A teacher has created a zombie virus. The entire school is zombies, and you and your class are the only survivors. Your nemesis, Nigel, laughs, saying that you'll become zombies too, and he'll finish you off. You break down and cry. Seeing this, Nigel realizes he's gone too far and apologizes.

Three hours pass. A few kids from the class decide to take a chance and open the door, hoping to be rescued. But there's a horde of zombies outside. Nigel, your enemy, suddenly rushes to your rescue. He grabs your hand and runs to the bathroom. Bursting in, he locks you in a stall while he remains outside. Taking off his shirt, he looks in the broken mirror and sees a bite mark on his shoulder.
