Other mistake: In Season 2 "Ten Little Warlords," Ares tells Xena that without a sitting God of War, peaceful people can't control their anger. Yet during the whole time in Season 6 that Ares is mortal, peaceful people can control their anger. Furthermore, in Season 6, Ares tells Xena that without the God of War the Goddess of Love becomes unbalanced. Yet in Season 2 there is no mention of this.

Revealing mistake: When Xena 'dies', her pulse is checked, and they can't find one, yet you can see her pulse in her neck. (00:30:30)
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.
