Zombie Apocalypse.

The zombie falls to the ground, dead.

"Why did you do that?!" Yells one of your teammates.

"Those were our friends!" Screams another.

You protest, "Guys, it was a zombie, those weren't our friend anymore!"

"But there could have been a cure! There could have been a CURE!"

"I'm sorry, but it attacked. Plus, we don't even know if there IS a cure!"

Your teammates scowl and remain silent.
