Continuity mistake: When the episode starts Xena and Gabrielle are talking in voiceovers. When they are shown from a distance, you can see Gabrielle wearing the outfit (long brown skirt and light blue shirt) that she wears at the beginning of season 1 (right after leaving with Xena and before being with the Amazons). She also isn't carrying her stick. The next scene in the temple she's wearing the green top and short brown skirt and also has her stick with her.
Girls Just Wanna Have Fun - S2-E4
Visible crew/equipment: When Gabrielle is entering the festival, after the camera is done showing all the dancers and returns to her, look at the right side of the screen by the entrance. There is a propane tank visible.
Revealing mistake: After Xena gets out of that chair, she does a swinging kick from her whip and you get a shot of her feet connecting with her victim's chest. The fake feet that are used are seen bending backwards.
Continuity mistake: During the battle in Callisto's cave hideout, Callisto leaves her sword behind when she runs to her chariot. When Callisto sinks in the quicksand, her sword and dagger are not seen. When Xena encounters Callisto in the underworld in "Intimate Stranger", Callisto's sword and dagger have reappeared.
Other mistake: As Xena and Gabrielle are walking along the river, the upper story of a modern A-frame house comes in and out of camera view in the upper-left corner.
Other mistake: When Callisto (in Xena's body) enters the cave hideout of Theodorus and his men, Theodorus assumes she's the real Xena. However, she walks in a Callisto-like way, indicating she isn't. Callisto's army never appears again either, not even after she becomes an immortal and a goddess. On her own in future episodes, Callisto still wears the same warlord outfit she wore when she led Theodorus and the army on village rampages.
Continuity mistake: When Autolycus jumps out of the dagger vault, the door swings shut. In the rest of the scene, the doors are open.
Revealing mistake: When Xena and Gabrielle are in the hot tub, there is a part where Gabrielle turns to face Xena, and when she does the actress stood up to far. You can see her bathing suit when she is supposed to be naked.
Blind Faith - S2-E18
Continuity mistake: When Xena ties Palaemon to the board, the close ups show the rope going through his palms, and around his wrist. When he stands up, the rope is tied near his elbows. (00:08:10)
Audio problem: In the scene where Xena is telling Gabrielle there is a side effect to the pressure point for sea sickness, one of those being you can't taste anything, Gabrielle comes to that realization and says "raw squid" but her mouth movements are "raw fish"
Revealing mistake: Just as Cupid's son flies up to get an arrow, you can see the wire holding him up to make him fly. Only visible in the quick shot of the child over the bed. (00:01:50)
Continuity mistake: There is a shot on the ground of all of Xena and Draco's body armor that they've taken off while arm wrestling. Soon after, Xena gives Draco a rub down, and her arm bands are back on. (00:18:10 - 00:19:30)
Continuity mistake: While Xena is putting back on all her armor after her swim, her hair constantly changes. First it is under her right strap, then over, then behind her shoulder, then back over her strap again. (00:22:45)
Audio problem: When Xena says "It seems so haphazard" the word haphazard is said with her Kiwi accent. (00:29:30)
