Avatar: the Last Airbender

After attempting to kidnap Katara and Sokka, Southerner Gilak leaves a haunting note for Hakoda: "Soon you will see the truth, chieftain". The vow leaves everyone on edge--including Katara, who remains wary of the two tribes' integration. As Northerner Malina announces a partnership with the company owned by Toph Beifong's father, her own brother comes forward to defame her. Have Katara's worst fears been confirmed?
