Sam held the door for a while longer, every scream tearing at him as she threw herself against the door. Gretel had taken care of him through his fever, they had spent a lot of time together and seeing her like this was deeply unsettling. The way she had looked at him and the force she was using to try and get to him, while gut wrenching, was oddly familiar. It reminded Sam of the people he'd seen affected by the croatoan virus. God he hoped that wasn't what this was.
It occured to him that if there was even a remote possibility then Gretel would have to be contained, for her own safety and the safety of the others in the compound. The last thing they needed was her to infect others and to have the place swarming with croats.
Sam sighed, this was not going to be easy. He eased his grip on the handle and stepped slightly to the side of the door, hoping that she would come through without noticing him and he might be able to grab her from behind, and with any luck manage to over power her without getting bitten in the process.
