I love Avatar: The Last Airbender and The Dragon Prince. I think Zutara (Zuko x Katara), Sukka (Suki x Sokka), and Taang (Toph x Aang) should be canon.
Aaron Ehasz is a phenomenal writer and I love his new show. I think Rayllum (Rayla x Callum) is adorable but I absolutely love Sorayla (Soren x Rayla) with a passion.
