Continuity mistake: Xena leaves Darius' house, where she forgets her chakram. Then there's a shot of her riding Argo, with the chakram attached to her hip. Later Darius shows up to bring the 'missing' chakram to her.
Trivia: This was the 2nd of a two part episode, and the script had to be totally re-written as a mostly Xena Free episode due to Lucy breaking her pelvis in an accident on the Jay Leno show.
