I have this headcanon for Book Two: Spirits of The Legend of Korra. Katara passes away near the end of the series and reunites with her friends and family. In the Spirit World, we see a young Katara laughing with her brother Sokka and Toph as Appa and Momo fly nearby; we see her hugging her mother Kya for the first time since she was a child; and we see Aang smiling with tears in his eyes as he kisses her again.
