Other mistake: In Season 5 the majority of the gods are trying to kill Xena, Eve and Gabrielle. However, what happened to the gods that didn't intervene, like Demeter, Hestia or Cupid? We don't hear about them again, but they weren't killed, so what happened?
Fallen Angel - S5-E1
Continuity mistake: When Amarice shows Joxer that Xena and Gabby are dead, Joxer immediately puts his right hand up to his mouth in anguish. The shot changes and instantly his left hand is over his mouth. (00:01:25)
Continuity mistake: In the scene where Gabrielle and Joxer are lining up the rockets, Gabrielle takes on a whole bunch of troops and she has armlets on matching her chin outfit, but when it cuts to Renee's stunt double, she doesn't have on the armlets. And it is like that throughout the whole scene.
Factual error: When ares says "In my brothers realm i have no power" What he should say is "In my uncles realm I have no power", as Hades is the uncle of Ares, not his brother.
Married with Fishsticks - S5-E15
Continuity mistake: When Gabrielle pushes Aphrodite into the cake, you can see her wig move back from her forehead.
Married with Fishsticks - S5-E15
Revealing mistake: In the scene where "Crustacea" is being hung upside down in the water by the children, you can see her wig detaching on the sides by her ears.
Looking Death in the Eye - S5-E19
Plot hole: Ares stops Xena from 'committing suicide' by sword on the beach after the chariot crash, before she drinks 'poison'. How did Xena know that Ares would stop her from 'killing herself,' thereby allowing her to drink the 'poison' when she obviously hadn't revealed any of her plan to him and she didn't believe that he was in love with her? (00:32:40)
Motherhood - S5-E22
Continuity mistake: When Athena falls on the ground after mortally wounded, she was not holding her wound. When her body was shown again, she is.
