Betrayal.

That's pretty common in my line of work. We're mercenaries after all. 

I didn't think anything of John walking at me. 

"You feel anything yet?" I scratched my neck. "Supposed to be some kind of energy booster... I don't feel anything."

No answer.

Just the same shuffling step and a glint of light in his hand. Knife...

Before I can ask, the knife is arcing through the air and I catch his arm by reflex, cursing.

But it's his face that gets me. Bloodied and deformed, and not two normal eyes but five, or is it six?

I'm eyeball to eyeball with a fucking zombie.
