Season 4 Episode 09 - Past Imperfect

Xena is haunted by her past when the village she is in is attacked the exact same way she attacked a centaur village when she was pregnant with Solan. Xena keeps remembering how she poisoned the village's grain and how she sent dead bodies floating up their river. She knows that she has to try and find away to stop the attack but doesn't know how she can defeat her own tactics, Realises that the answer is in the past Xena starts getting flash backs of herself when she was defeating the Centaurs and trying to find the Ixion stone. Then the unknown attacker becomes clear to Xena, it is a woman who helped her though her pregnancy with Solan called Satrina. Satrina always wanted to tunnel under the walls to the village back then so Xena realises that this is what she is doing now. Xena tricks Satrina and defeats her and therefore saving the village. But the pain is not yet over as the flash backs still continue at the end of the episode with Xena giving up her now dead son Solan to Kaleipus of the Centaurs.
