Well this seems to be something many fans have been asking for and asking for. According to information on this site Evan E. will be reprising his role of Kyle Harman, aka Horatio Caine's son in episode 12 in early January. The episode is called "Friendly Fire". While the murder under investigation has to do with the inventor or a gun. The gun is supposedly faulty and someone is still trying to sell it to the military. Where does Kyle fit in? Is he hurt? Does he hurt someone else though it is not his fault? Is there a totally unrelated reason?
