Sokka got injured a few days ago. He had a few wounds on his chest, arms, legs and back. He was in bad shape.

The Gaang (including Zuko) had left on a mission and you staid with Sokka.

You see Sokka in the lake with his hair down, he was struggling to stand, and now he was in water! You get to him and see he's holding on to a rock, from how tired he is. He looked like he wanted to wash his hair and have a bath.

"What?" He asked when he saw you. His voice was tired yet aggressive and defensive.
