Clara.
That tale of the brave Oswin Oswald in the Alaska Starliner in the Dalek Asylum? The barmaid and governess of Victorian London? Some of the incarnations of Clara Oswin Oswald. There were many across time, many were lost and forgotten. But the voice of their actions remain. Saving the Doctors throughout time, undoing his defeats and correcting them to victories. This is Clara Oswin Oswald.
Clara found herself flying through the Doctor's timeline, finding another defeat made by the Great Intelligence to undo, and saving the Doctor, every incarnation of him. Eleven.
She saw the Doctor's past victories, but they were really Clara's. She felt proud. She wasn't only saving the Doctor, but the universe.
But alongside his victories was his tragedies. Clara saw the sadness that the Doctor tried to hide from Clara, but he can't hide it anymore. One minute, she was looking at one of the Doctors, the Tenth incarnation, she thought. It was a beach setting. He was facing a blonde girl. Clara saw the tears in the Doctor's eyes, as well as the blonde girl's.
"Rose Tyler." the Doctor had said, and faded away. Clara saw the blonde woman's tears again, with another woman, her mother, at her side. Clara didn't understand why she had to go through these tragic moments.
Another moment flashed in front of her. The Eleventh incarnation. The clever boy she knew best. This time, it was set in a graveyard. No doubt it was going to be tragic. There was the Doctor and that River woman that Clara had just met, knowing her as the Doctor's wife. Another woman was present, however. She had long, red hair, and she was standing next to an angel statue. One that Clara found to be a bit strange. There were tears in the red haired girl's eyes. She had lost something.
"Raggedy man, goodbye." the red haired girl said, and vanished into thin air. Suddenly, something was inscripted on the gravestone she stood by. Then the moment vanished from her thoughts.
But there were some memories where the Doctor was truly alone once again. Another moment flashed beside Clara, of the TARDIS. It looked a bit different from the one she was accustomed to. This one was orange, and was smaller. There were pillars by the console, and there were more of those round things. She recognized the lone Time Lord as the Tenth incarnation of the Doctor.
He walked around the console with a regular pace, his expression clearly not showing any happiness, Clara thought. He stopped, and Clara saw his face closer.
"I don't want to go."
The memory faded instantly, and surprised Clara. Suddenly, a bright flash was present in her eyes, she closed them, and everything silenced.
The ambience of the Doctor's timelines ceased. There were no more tragic memories. It was time. She was in the Doctor's memories, rather than simply viewing them. It was her move this time.
