"Good question, let me explain. To skip most of the boring details, I was detained in this base, Christie found my cell on guard duty, and I struck her a deal. She gets to kill me if I become a zombie. Well, she jumped at the offer and convinced Alan, through lies I'm sure, to give her a sample of the virus in a vial and a syringe. Christie breaks me out of prison and infects me, at which point I begin writing down my symptoms as per our agreement. I thought I would become some shambling buffoon and be bludgeoned to death, henceforth putting me out of my misery. I start hearing voices in my head before I pass out in excruciating pain and 'die', if you can call it that. By a strange twist of fate however, I find that not only am I a special infected, but I am mentally and verbally able to not only control the zombies, but hear them. So every infected from the standard shambler to the strangest and strongest of special infected reports to me now, and I can hear every word they want to say with every moan." Jack said neutral faced as he looked at them.
"I can and I will let at least one of you leave. Lisa, you are the last bastion of pure humanity I have seen since this began. You are selfless, honest, altruistic to an unquestionable degree, and most importantly, innocent. I hold nothing but respect and the highest regard for you, so if no one else will survive this, I will make sure you do. I am not so sure if the other two of you will live or die, but that is Lisa's choice. I will let Lisa keep those close to her alive as she deems fit, but if any of you try to stop me or the coming evolution, I will not hesitate to stop you. That is my deal and the terms are non-negotiable. Kaufman will die though, that is not up for any debate or discussion."
