VII - The Chariot (Xena & Ares)

When Xena and Ares get together they are unstoppable, and so 'The Chariot' becomes their mode of transport. Note here that Xena's costume duplicates the card rather well. The Chariot is hte unstoppable force, although it also suggest stasis as its energy is not used to best purpose.

Before joining Ares, the soldiers strip Xena naked. This could be taken as an image of the Star, but as the same thing happens to Gabrielle I'm not convinced. The nakedness is more representative of the two heroines getting stripped down psychologically to begin the healing process.
