Peace on Earth is an example of a few production scheduling issues the series suffered from during it's run. Intended to be aired after the five part episodes involving the introduction of character Princess Aleta, this episode was aired early to fit the Christmas timing of the year. During the episode a young women, from The Misty Isles, Lady Daniella, attends the celebrations in Camelot on behalf of Hugo and Aleta. Denys gives Daniella a necklace, a gift from Valiant to be given to Aleta. The character of Aleta has not yet been introduced into the series, and Hugo is still an enemy of Camelot. The early airing of Peace on Earth distorts the story flow and should be ordered after The Parting for continuity sake.
