Really i can't fantasize Gabrielle living and fighting without Xena. What did she became after Xena's death? Maybe she became a great warrior trying to keep alive the memory of The Warrior Princess. Like Xena did when Lao Ma died ( she tried to keep alive her memory and she was folowing her way).
Gabrielle is a perfect warrior with many skills and very very smart! Maybe she couldn't live without Xena. Xena was the reason why Gabrielle became that warrior. Maybe it was very difficult for her to live without Xena (her soulmate). Maybe Gabrielle went to Eve. To travel together like mother and child.
Maybe Xena became the angel of Gabrielle!!!!
