Seasons 1-3 Gabrielle isn't really involved with Ares. In fact she seems to give him the benefit of the doubt in the Quill is Mightier, even becoming slightly friendly with him. In fact we don't see her angry and against Ares until Chakram. I'm not saying they were friends and in the furies she used her knowledge of Ares to save Xena.
So here's my question... I'm not too concerned about why we as writers of shipper stories do this to Gabrielle (usually it's just easier). I want to know how we as shippers view Gabrielle in regaurds to Xena and Ares' relationship.
