"Right. Okay. Interesting."
"What's wrong? You're acting like we've never done that before."
"We haven't."
"We haven't?"
"Oh, look at the time, must be off. Um, it was very nice, it was…it was good, it was uh…unexpected. You know what they say, there's a first time for everything."
"And a last time."
After the Doctor had left, and she was left standing in her prison cell, wishing it didn't have to be this way. That maybe, just maybe, she could go with them, and just travel forever with her Doctor. He would never forget her then. They would make so many new memories together, ones that they both hadn't have lived before. Everything would be okay.
But no. She gripped the iron bar of the cell and squeezed her eyes shut, feeling her defenses not slowly falling, but faster and faster with each longing thought. She knew very well why she couldn't, and it obviously didn't do her any good to dream about things that could never ever happen. But wasn't the way they rolled always going for the impossible…?
No, stop that thought right now. It was enough to know that he had wanted her to come with him. But it would really never be enough. To know that at one point, one small point in time, he had loved her. That she had been the luckiest girl in all the galaxies, in all of space and time.
He had forgotten her. Not completely, but the fact that he knew her less and less…it burned a hole in her heart. One that could never be replaced. One day, that worse day that was coming for her which she could not avoid. Where he would take a look at her face…and there would be no recognition in those beautiful eyes.
She truly thought that it would kill her.
