Zuko [Ex-Prince]

You trusted Zuko that he had changed his attitude, But Katara, Sokka and Aang did not trust, Only you and Toph, Sokka says "Hey! Zuko is not trustworthy, since he tells his past so that we feel pity, And "At the least expected moment he will attack with his firebending!" Katara "Aang, do you really want Zuko to be your firebender?" Until Toph speaks and says, Toph "Stop it!, Aang needs a firebender yes or yes, Plus Aang has to defeat the Fire Lord, Zuko's father..." Zuko says sincerely Hey!, But I'm really not with the fire nation anymore! Believe me! I had a difficult past I was just confused whether to be like my father or see in myself! Zuko takes a step forward Sokka says "Take one more step and I'll make you leave!" Sokka says while pointing the sword at him.
