The car crash that kills Shannon's father is the same crash that nearly crippled Jack's future wife, Sarah. When the doctor is talking to Shannon and her stepmother in the hospital emergency room, you can see the younger-looking Jack walk behind Shannon.
There are two unaired flashbacks scenes in this episode. The first is between Shannon and her step mother at her fathers wake. They discuss beef stroganoff. In the other Shannon visits Philippe's home, and meets his wife Dominique. Both these scenes appear on the Series 2 DVD.
