While the survivors under Zane's control had begun a baptism of fire, one that would leave only 1/5 of them alive at the end of it, but would at the same time significantly strengthen their group over all. Ryan's group was once more running out of supplies.
After all, Ryan had a significantly larger number of students and faculty following him. And until now, he had not sent out patrols or scavenging parties. They were relying entirely on what he and Mr. Diaz had managed to take from the cafeteria.
