Lucy Lawless was actually naked in the sequence where Xena is standing unclothed in the middle of a town square, threatening to punish the villagers for some imagined wrongdoings. Her bare buttocks were glimpsed and only her bare shoulders and upper chest were seen.
Argo is back after an absence of many episodes.
After Xena is struck by madness, she asks one of the ruffians what is the capital of Assyria. This is a nod to Monty Python and the Holy Grail (1975).
In Greek mythology, the Furies were the three goddesses of vengeance: Tisiphone (avenger of murder), Megera (the jealous) and Alecto (constant anger). They were also called the Daughters of the Night, but were actually the daughters of Uranus and Gaea. Without mercy, the Furies would punish all crimes including the breaking of rules considering all aspects of society. They strike the offenders with madness and never stopped following criminals. The worst of all crimes were patricide or matricide and first and foremost, the Furies would punish this kind of crime.
