You were unarmed because your group just kicked you out

While trying to find some place to hide, you were attacked by a zombie

You tried to wriggle it out of its grasp, but it was futile. Accepting your fate, you closed your eyes, hoping the pain wouldn't be too much

But the grip the zombie had on you suddenly disappeared

When you looked down, you saw it had been massacred with a machete

"It didn't bite you, right?"
