This episode sees Xena still trapped inside Callisto's body, to cover for Lucy Lawless breaking her pelvis. The episode was actually originally written as a standard Xena episode, with the body swap shoehorned in at the last minute.
Hudson Leick makes a great stand-in Xena, and at times it's even almost possible to forget about the change.
This is the first time that we see Ares as a mortal, and Kevin Smith plays it well, with good comedy timing.
We also encounter the slippery King Sisyphus again, previously seen in the first season's 'Death in Chains', and 'Hercules: The Legendary Journeys'' second season episode 'Highway to Hades'. Here, episode director Charles Siebert takes over playing the role, although the character is essentially the same.
Gabrielle and Joxer don't really have much impact on the plot, but the few scenes where they follow Xena and Ares to the island, and slowly start to go mad as they wander around the caves, are fairly amusing, and it's great watching Gabrielle when she's angry(!)
[Mild spoiler] At the end of the episode, in return for her helping him, Ares returns Xena to her own body, although it is clearly a stock close-up of Lucy Lawless used, and a double as she walks away with Gabrielle. [End of mild spoiler]
This is a fair, watchable episode, but beyond the novelty of Xena being in Callisto's body, it is a pretty average one.
