Lee

History
Lee was the second son of two Earth Kingdom farmers, Gansu and Sela, and had an older brother named Sen Tzu, who enlisted in the Earth Kingdom army to fight the Fire Nation.

Lee is the boy Zuko meets in "Zuko Alone". Zuko first meets Lee when he is buying food for his ostrich horse and himself. Lee and his friends throw some eggs at Gow, and quickly leave. Seeing Zuko as the only one around, the Gow blames him and take his food. Lee regrets getting Zuko in trouble and invites him to his house for food. Lee warms up to Zuko, thinking of him like an older brother. Lee also reminds Zuko of himself as a younger child. Late at night, Lee steals Zuko's broadswords and practices with them in the fields. Zuko wakes and confronts the boy, but instead of scolding him for the theft or the harm Lee could do to himself, Zuko gives Lee a short lesson on how to use the broadswords. Before he leaves, Zuko gives Lee his knife, the one given to him by Iroh and the one used to cut his knot in "The Avatar State." After a confrontation with Gow once more, Lee pulls the knife on them and is taken away from his mother. Zuko eventually rescues Lee from the guards but uses his firebending to do so. After the battle, Zuko tells Lee to keep the knife, but Lee quickly shuns him away, refusing to take the gift and saying "No, I hate you!" after realizing Zuko's origins.
