Sara's mother laughed while imagining how William would react when getting attacked by Jacky, "this isn't your typical spirit master, he is one from a mysterious force that I accidentally tapped into. If normal methods can't deal with you, then let's see how Mystic ways will, hahaha!"
She was quite confident in Jacky's ability to kill William. Jacky wasn't a strong master himself in the outer world, but he inherited weird methods from the master she once assassinated. She knew from that mission about the existence of that weird side of Mystic Arts. and since then she made sure to keep Jacky around.
Jacky would never guess it, but a big part of his affection towards her came from her mind games that she kept playing around him. She knew how special Mystic Arts were, and what was weirder was that no one else in the palace knew about that side of the world.
