Extend the Story - Add a Room

"The key is my only option." you think. Dave limps towards you slowly. You walk toward him slowly. "I'm sorry Dave." you say with guilt. He falls to the floor as you kick him in the back of the leg he tries to get up as swiftly as possible, but a kick to the head ends any hope of that happening. You quickly grab the key and stab him in the head multiple times. His body goes limp, turning the ground around his head a scarlet red. You start to feel the tears in your eyes but brush away those feelings. That wasn't Dave, that was a zombie, not a human.
The radio turns on from inside the car. A faint voice could be heard from inside, stating the beginning of the zombie apocalypse. You had no where to go and no plan to follow. For the first time in a very long time you felt:

Scared.
