Plan
Hope's soul situation right now could be said to be a complete mess. Because the inappropriate palm technique had been used, all of her souls had bits and pieces of it taken away.
It had to be remembered that Old Wan's initial target was Ryu, so he had used the Yang version of his palm. But because his target ended up being Hope instead, an unexpected variable, things went wrong.
Back then, Old Wan hadn't even known about Hope's existence because she was always hiding within Leonel's world. Otherwise, he would have certainly planned for such a potential outcome.
Regardless, this ended up being both a good and a bad thing.
The good was that since Old Wan had used the wrong palm, it was impossible for him to use Hope's soul like someone of this Taboo Path might have otherwise. As such, Hope wouldn't have to suffer the usual rounds of humiliation and Dual Cultivation she might have had to otherwise.
