Remain in Themyscira. It's home now.

Bruce trained just like before after her parents were murdered. Just this time it was a little different. She wasn't learning to make her body into a weapon so she could become the Batman. No, now her body was already a weapon. A damn fine one at that. She was practically a walking nuclear arsenal.

Maybe Bruce felt bad at one point for having contingency plans to take down the Justice League should they ever become evil. But now that she could experience how powerful they are firsthand with powers of her own, without a doubt they needed to be put in check somehow.

She was taught by the strongest warriors Themyscira had to offer: Diana, Artemis, Donna, Cassie, and countless others. Her powers took some getting used to but she got the hang of them with time. She even learned to use her equipment. The vow to not kill seemed null and void now that she carried a sword.

Over the course of several months she became acclimated to her new home. She was Wonder Woman now and the champion of Themyscira. She needed a new name. Bruce didn't quite fit her extremely feminine body. So she took on the name Brianna. It was in honor of Diana yet still clung to her original identity.

Gotham had plenty of vigilantes there to protect her in Brianna's absence. Damian would likely inherit the Wayne family fortune and become the Batman once he got old enough. The new Wonder Woman was only a call away from the Justice League should they ever need her help. In the mean time, she just served her queen and protected her lands while continuing to learn more about her heritage and the ways of the amazons.

The End
