Continuity mistake: When Callisto and Xena first battle on horseback, Xena knocks Callisto's sword to the ground and Callisto escapes. When Callisto is training with Theodorus and the army at their hideout, her sword has reappeared, although she didn't pick it back up at the village.
Continuity mistake: When Xena starts chasing down Callisto after the attempt on the Oracle's life she has her sword in the sheath on her back, as can be plainly seen when she jumps on Argo. A couple of seconds later, there are a few shots of her charging after Callisto without her sword, which comes back in the sheath once the chase gets in open field. (00:23:00)balistener
