||During the fifth season, Xena gave birth to a daughter, Eve, whose birth was believed to herald the end of the Olympian Gods. Her background is...unique.
Eve was conceived in the episode Fallen Angel [91/501], when Callisto touches Xena as a gesture of forgiveness. Xena learned that she was pregnant in Animal Attraction [94/504], but was bewildered as to how she got that way. The mystery was solved in Seeds of Faith [99/509], when Callisto reveals that she "gave" Xena the child as a way to make amends. To make matters more interesting, she tells Xena, "my time has come to be reincarnated into the mortal worldand the body that will bear my spirit has been ordained. I can think of no greater mother than you."
Callisto, therefore, is both father and child!
