Tanya looked at Zara for a long moment before saying in the most even and cold tone of voice she could muster.  "Pleased to meet you Dr. Miller.  What do you have your degree in.  You know I was actually surprised when I was told that Dr. Raker was going to be taking over as Elaine's personal Doctor.  There really isn't any test or act that I can think of that has not already been performed on either of the twins.  Unless it has something to do with the two possibilities for why you Dr. Raker might have been invited here without having to give them much thought to the subject... The first has been tried before and has failed miserably but that does not stop them from trying again and again.  They want to clone the twins and sell off the clones as the ultimate expendable soldier.  The problem is doctor the twins share a gene that no one has been able to identify making it impossible for them to be cloned.  The second idea is even more simple... Doctor what would happen if someone were to take the results of your research and reverse your 'repair' process?
