When Geoffrey is making his confession to the family, we learn in the video he shows that, fittingly, his last name is Butler.
The title is a play on the phrase "tis better to have loved and lost than to have never loved at all"
Duane Martin makes only one other appearance on the show, when he plays a doctor, as well as Hillary's brief love interest, on the season six episode, "I, Ooh, Baby, Baby."
When Geoffrey has the family gathered he says "I beg your forgiveness for bringing this pox upon your house." He's paraphrasing a line from Shakespeare's "Romeo and Juliet" in which Mercutio curses the Montagues and Capulets as he is dying by saying "A pox on both your houses."
