The final lines in the episode are a slight misquote of John Greenleaf Whittier, "Maud Muller" (1856); the actual quote is, "For all sad words of tongue or pen, the saddest are these 'it might have been.'"
The guest star in this episode is Melissa Anderson (of Little House On The Prairie fame) who is married to the co-creator of "The Equalizer" Michael Sloan.
