You had been banished from the fire nation because you escape there ship when everyone was on the land. You had tracked Zuko and headed his way. He thought that you weren't going to come his way to be with him so he tried to get over it when you found him and he saw you, he realized you didn't want to be there alone. After walking to the others because you were with him now. When Sokka and Aang saw you, they're jaws dropped at how pretty you were. The way your black hair swayed through the wind, with that red rose in you hair. Katara stood there with her arms crossed with pride because she wasn't the only girl anymore.

"I thought he was the only one banished from the Fire Nation?!"

Sokka screamed in confusion yet also suprise because if how pretty you looked. Katara put her arms on her hips with her smile still there on her face.

"At least I'm not the only girl here now!"

Kataras voice was filled with pride, and happiness not that you were here despite you being an ex fire nation queen or whatever.
