I nodded my head woodenly, trying to follow her."Well in one of those science classes we talked about cloning. Did you know that it is theoretically p...ossible to recreate an entire organism or being, from a few of its cells? Each and every cell contains the genetic blueprint of the organism. So when my bitch of a mother gave my fucking kidney to your girlfriend, I had my way in.
