Sokka slowly made his way down another hallway. It was so hard to keep his eyes open these days. Sure, he slept every now and again, caught thirty minutes there, an hour there, but never too much. But the dreams followed him into his waking hours and it seemed as if he would never be able to rest now. He jammed his hands into his pockets, clenching his teeth. He would get through this. He would. As he came to a corner, a flash of movement caught his eye. A vague figure, dark haired and dressed in the clothes of the Southern Water Tribe. His breath caught in his throat. No. It couldn't be...

"Mom?!" He turned, following the shape as it moved down a corridor, around another corner. He sped up, trying to get another glimpse.

"Mom!" He sprinted around the corner to follow and barely caught himself, arms flailing, as the floor dropped sharply away. He reached out, snagging the wall before he could tumble into the dark pit.

What was going on here?
