Until this episode, we knew almost nothing about Quincy's past life or at least his life before the show started. In this episode we learn some maybe surprising facts about Quincy's past life. We learn that he was married once to a woman called Helen, that she wanted kids while he didn't want some, at least not "now". Later we learn, that Helen got a brain tumor and died of it, and that Quincy blames himself for the death of his wife, because he didn't have enough time for her and didn't see the symptoms of the fatal illness. People who see this episode maybe will see Quincy in a different light now. You could say that this is the first episode in the show, where Quincy is portrayed as a "normal" person with personal issues, and not (or at least, not through the whole episode, because he also solves a crime in it) as the kind of superhero, as which you could see him in most of the episodes of the show.
