“No, Xanatos," Obi-Wan said. "I grieve for a life lost. And I thank all who taught me for my grief. It does not make me weak. It makes me strong."
Suddenly, Obi-Wan's lightsaber whirled. Qui-Gon was astonished at how quickly and gracefully the boy moved, leaping off a mound of lava to strike at Xanatos. Xanatos stumbled backward from the ferocity of the attack. A cloud of steam suddenly erupted, and he quickly lurched to one side, losing his balance and landing on one hand.
"Stronger than you," Obi-Wan added fiercely, leaping after him.
Qui-Gon followed, admiring Obi-Wan's focus. Now the two fought as one. Xanatos had weakened, and they used this to drive him back, back against the black pool. If they could get his back against it, they would be able to disarm him or defeat him. It would be his choice.
