"There's no turning back now. Cheryl tried. It was her watch. She tried to save her friend, but failed, leaving a scar on her eye. A bank heist gone wrong and her partner/best friend died trying to stop them. Not before Cheryl got in one shot in, albeit too late.

It was bad order's she couldn't follow knowing the situation was getting worst. She saved other's but that didn't stop her from blaming herself from doing more. Many other officer's and family tried to comfort her and she thought about completely giving up. But she couldn't when others thanked her for being there to help, giving her help too and for helping those in need. And other's needed her now.

Animal's going crazy and eating each other, chaos from beast's trying to survive and kill their way to safety, but weirder, the dead attacking the living. Some order's being to kill some of the survivors to keep the larger group alive seemed worse than what was happening. She made her choice, protect everyone she can, take down the hostile civilian's, fight off the dead. There's no turning back now."
