Armageddon Now: Part 1 - S4-E13
Character mistake: Callisto's sword is missing. When she appears in the Xena Season Three finale "Sacrifice", her sword has reappeared. It is never explained why Callisto doesn't have her sword during her three appearances on Hercules the Legendary Journeys.
Answer: It's a matter of plot. Having multiple characters who basically would have the same purpose, to kill Hercules, complicates and confuses the story line. It would lose the focus on the characters themselves and the interaction between them. In film and literaturea, characters, plots, scenes, etc. have to be crafted in a way that serves the story in an understandable and satisfying way for the viewer.
