The angel from this episode was intended to have made a return in season 3 had Cara DeLizia and the original executive producers had stayed. The angel would have played a major role in helping Fi discover her true destiny.
Mackenzie Phillips performs the song "More Like a River" in this episode. The song is about Molly having trouble expressing her feelings for Rick, and how even after he's gone, she has trouble moving on from the memories.
In a scene where Molly is playing her guitar and singing the notes of a song that she plans to write in the future - the song is "She Sells", which she does sing in a later episode in season 2.
