"Are We Okay?"
On a run to a fire-station for fuel, the group are cornered by a large group of infected. Trying to get out, Simon is bit. Though he tells the others to leave them, Dexter attempts to get him to safety. Dexter then twists his ankle, dropping Simon and causing the dead to pile on him, devouring him.
