 PLOT: In this episode, we learn that "Miles" is really a mob  informant in the Witness Protection Program, and that his name is  just a pseudonym. He also mentions that if Rose is to be with him,  she can no longer have contact with any family or friends. However,  in Season 5 Episode 15 "Triple Play", "Miles" has an adult daughter  who comes to visit, and calls him by his pseudonym, meaning that the  mob informant story line was something created after Season 5  Episode 15, not before.
