"love" at first sight

Chapter 4

~Alisa's Pov~

I couldn't do it. I tried to, but I couldn't. It would have been so easy to slit his throat then and there, but something in me just wouldn't let me. I stood there, still and silent. I guess the bastard was waiting for me to move first because he stood still as well.
"Do it," Colton says.
"I-I can't," I stutter.
"C'mon just do it."
He was trying to make me pity him and let him go, but that's not how I do things. I settle for his arm. A deep cut that probably hit bone. He screams in agony and falls to the floor while I watch in pleasure. His fresh blood splatters the wooden floor and he gasps for breathe. I stand over him like a lion over their prey. I punch him, hard in the nose. He yells again with blood covering his face. A couple more blows to the face and he's knocked unconscious. I drag his limp body to his couch. The rope that I had escaped from so easily was where I had left it, on the ground beside the couch. I find more rope in a hallway closet and I tie him down. I make sure to double knot so he can't escape. I'm not sure how long it is until he finally wakes up. It could've been minutes or days, I was too busy talking myself into doing it. Into killing him.
"Why didn't you kill me?" Is the first thing that escapes his mouth.
"I don't know," I respond calmly.
"You're a CEK."
"A what?" I ask.
"A Chemically Effected Killer," He explains.
"What is that suppose to mean?" I ask annoyed.
"You're programmed to kill. I've only heard myths about people like you, I didn't think it was possible. The chemical that escaped with the bombs, it's making people ill."
"What do you mean by ill?" I ask nervously.
"Well for few, like you, it makes them kill crazy. But for most of the country it makes them age ten times as quickly," Colton explained.

The bodies. The empty streets. It now all made perfect sense.

"You're different, you didn't kill me. Why?" He asks.
"I don't know, I was about to. But-But I just couldn't. I looked at you and my arm froze." I say.
"Well clearly you aren't completely gone and I know where to go to save you."
"Where?" I ask.
"California, I can find us a ride," he says.
"Okay, but you didn't tell me, how does the chemical affect you?"
"It doesn't, I'm immune." He says.

I'm packed and ready to go in less than ten minutes. With nothing but the clothes on my back and a bag of few belongings I head to an unknown destination with a boy I barely know in hopes of an antidote.
