Zuko was just crowned Firelord of the fire nation after his father, Ozai, was defeated by Aang..He seems excited to right his father's wrong & change the fire nation

But, the prisoners from Ozai's control, you being one of them stayed. You were (u choose)-bending & Fire Nation guards caught you and threw you into jail for 5 years, there were four parts, all having weaknesses for water, fire, earth, & non-benders. The guards let you & the other prisoners see Zuko's coranation to Firelord.
