Sidious noticed Maul's reaction and said to him, "That is correct. I am prepared to lose you—what I most value. So must you be to become a Sith. You must be prepared to lose your own life in order to win."
His wound festered. The pain was blinding. He had no doubt that death would come soon. He thought he was hallucinating when he saw a cloaked figure at the mouth of the cave. It was Sidious.
Maul seized the Force, let it whip him up and to the side as if he were attached to a giant elastic band, The metal behemoth missed him by millimeters.
Sidious parried every blow, but Maul could tell his Master was working hard to keep him at bay. As Sidious backed up against the wall, he said, "You want to kill me? You want to kill your Master?"
"Yes," Maul grunted.
