People really underestimate this relationship and favor Katara’s grief over Aang so much that we never really get to see fan art of her and her brother.
Ultimately, I feel like Sokka’s death had the potential to hurt her the most - especially if we consider that Aang could have died before him, and she was all she really had left.
But that’s all speculative.
