Thalia PoV
So many years had past since her friends left the world. Her world. But she couldn't leave unless she fell in battle. As years past, the faces of her friends dimmed quickly, and she was slowly losing her grip on the memories that once made her happy. As she battled to keep the memories with her, her own life seemed dim. Every single day seemed the same, the only difference was that every day the memory of one friend would fade, and soon she was only left with a few names. Every time a memory left, she would start panicking.
In order to remember her friends, Thalia had stuffed a photo in her pocket, it was from the end of the giant war. Every night she would see how many people she could recognize. But even the picture didn't help. Soon, Percy, Annabeth, and even Jason were forgotten.
Many Months later
Thalia was rummaging through her bag when she found a piece of crumpled paper in the pocket of her parka. She carefully straitened it out. It was a photograph. Thalia vaguely remembered putting it in the parka. In the picture, there were many faces that she didn't recognize smiling at her. The only person she recognized was herself. She didn't remember meeting any of the strangers.
But the strangers weren't any strangers, they were strangers she used to know.
The End
