On the island, they find Lian, making more machines. She fears that Aang will not be able to master all four elements before Sozin’s comet arrives. Aang refused her help, seeing as how the machines were disrupting villages. Lian then voiced her contempt for him as she sends a machine to fight them to flee to the Air temple, attempting to destroy the Avatar statues. They stop Lian, but Katara, Sokka, and Haru are captured by another machine.
