AHSOKA: What do you want with Anakin Skywalker?
MAUL: He is the key to everything.
AHSOKA: To bring balance to the Force?
MAUL: To destroy. He has long been groomed for his role… as my Master’s new apprentice.
AHSOKA: You lie.
MAUL: I’m afraid not. In fact, I was so certain of his fate that I orchestrated this war to lure him here with Kenobi, to kill him. Thus, depriving Sidious of his prized pupil.
