The little girl in a Rat costume who looks like Ashley is her little sister Anastasia N. Ali. She also played as Bashley in the 100th episode "What's Will Got to Do With It? (1)".
This is one of the few episodes to feature the opening immediately into the episode (with no prologue scene).
The title is a reference to "Someday My Prince Will Come".
When this episode premiered on BBC1 it was aired as with the preceding part in a 45-minute special for Halloween.
