We flashback in time to see what really happened before Horatio got a DNA analysis from Maxine Valera saying Horatio's son was involved in something. In the beginning of the flashback, we see S.W.A.T. units and the CSI team closing in on a mystery man's home. But instead of getting caught, the mystery man jumps right off the building roof and in to a boat and manages to escape. Afterwards, Eric continues being jealous of the new relationship between Calleigh and Jake Berkeley and Horatio faces emotional moments with his son.
