okay everyone seems confused so I will post some pictures
Tahn
This is an Earth Kingdom refugee heading to Ba Sing Se with his family. He is a jolly man who is always happy to say hello to fellow refugees. Tahn has been traveling for months up the west coast of the Earth Kingdom with his wife and sister. The three of them fled from their home in the south after their village was raided by the Rough Rhinos. Tahn and his wife, Ying, crossed paths with Zuko in Book 2 Earth - Chapter 7 ??? they are the couple Zuko stumbles across in the opening scene.
Ying
This is Tahn's wife. She is surprisingly nice to be around even though she is nine months pregnant. She is a very optimistic woman ??? hopeful about what the future will bring for her and her family.
Hope
This is Ying and Tahn's new born baby girl that Ying gives birth to on the Serpent's Pass. When Aang sees how happy and hopeful the baby makes them, he remembers how he feels about Appa.
