John,
Thanks for the FDK!
CJ is a child of the 21st going into the 22nd century. Even today we have HS students taking AP classes and getting college credit. It is conceivable that in 2108 an 18 YO can be completing his college degree.
Sorry if you were confused, but they are two separate and distinct entities. I've seen stories where there are dire consequences for two incarnations of the same individual meet, however I do not subscribe to that. The only problem would be in the older tried to harm the younger, because he would be harming himself. Think 'Butterfly Effect'.
Also, keep in mind who his parents are. He would have inherited the eidetic memory of his sire which would make learning easy.
I, personally, have encountered a number of 18 YO's and even some younger that are very focused and know just what they want to do with their future.
