I watched the first Xena episode last night and also read a bit on Wikipedia. Given that I am a first-timer and don't really know what I'm looking for, these may be a stretch but I'll throw them out there.
Mention of Xena's crucifixion made me think of Jesus so… jesse
The villain in the first episode, who is a former colleague of Xena's, is named Draco so… Drogo
And Ares is Athena's brother
