Horrifying the Horror: Done well here. In all of Ares's appearances he seems perturbed about something and strangely insistant that Xena destroy a particular temple in Brittania.
Left Hanging: Right before the climactic battle with Caesar, Xena notices the strange storm over the temple and rushes to help Gabrielle. There is no resolution whatsoever to the Boadicea/Caesar conflict, and in the following episode neither character is even mentioned.
Red Herring: Caesar is made out to be the episode's main villain, but he's just the distraction.
Rewatch Bonus: All of Khrafstar's interactions with Gabrielle suddenly become chilling the second time around. It's possible that the only reason he ever yelled "we will never give into Caesar!" was to get Xena's attention in the first place.
Title Drop: By Khrafstar after his transformation.
Khrafstar: Thank you for Gabrielle. Xena: I don't know what you're talking about. Khrafstar: Look inside yourself. You brought her here. And why did you come? To defeat Caesar. Your hatred brought you here. Dahak appreciates rage.
Wham Episode: The seeds for the Rift arc are planted, while Dahak and his cult are introduced. Additionally, Gabrielle loses her blood innocence, which had been an issue since the show's early days.
Wrong Genre Savvy: Because she believes Khrafstar's people worship the One God of the Israelites, Xena assumed Ares simply wanted to eliminate a rival religion.
