I don’t think she had any weaknesses. She was a higher power unto herself - humans are the ones that have the weaknesses. All Delvians are highly evolved and Zhaan was the only Delvian able to be violent. It’s completely against a Delvian’s genetic structure to be evil or anything less than blessed, but because there was some kind of genetic hiccup she was able to be evil.

That’s why she was chosen to be a political activist. Zhaan killed an evil dictator to save Delvia, and that’s when she was caught by the peacekeepers and shunted off into jail.

Maybe in her own mind she saw [herself as] weak for not being able to give more love to everybody. She didn’t see herself as perfect and I think she wanted to. I think she probably would have seen a weakness in that she was not able to completely rid herself of the dark side. She so desperately wanted to; she prayed everyday to try to rid herself of it and it took her hundreds of years, yet she still reverted. Which was fabulous, as an actor to play, that kind of complex character.
