sokka trying to get katara to give up on her waterbending bc it could get her killed. and katara refuses to give up and continues to practice anyway. bc sokka and katara represent the survival of both the people and the culture. sokka had the safety of their people thrust upon him by his dad, while katara is the only one in their tribe that can carry the weight of their culture. both are heavy burdens, and they're struggling with their roles bc they're just two kids trying to rebuild in the wake of genocide. but they refuse to give up, bc that's what the story is about.

holding onto hope, regardless of what you face.
