This is the first "clip show" of the series, where clips are shown from previous episodes, as the characters reminisce.
In the first remembrance clip, Kelly does the hula (Hawaiian dance), in the second she performs a veiled dance (not quite a belly dance, but Arabic nonetheless). In both instances, Jaclyn does well, although neither dance is performed properly, which is as it should be, because Kelly improvised in both instances. In the third clip, Kelly is at the circus, doing the can-can, a French---Parisian---dance, then ice-skating. In real life, Jaclyn Smith had studied ballet.
This is the first directorial credit for Kim Manners. While he would go on to have close to 150 directorial credits, he is best remembered for being the producer of the cult classics The X-Files (1993) and Supernatural (2005).
Even though the Angels, Bosley and Charlie are reminiscing about their past three years of working together most of the cases they talked about were only ones that featured Chris and none with her sister, Jill Munroe.
