Author's Note: And it's finally finished! This story took about twice as long as I expected but at least it finally got done. Hope you all enjoy!
The fight was over. All five of them stood on Bad Wolf Bay, a Doctor on each side of Rose. Tears streamed down Rose's face, her emotions going in every direction. Her Doctor was trying to leave her, and yet here was another version of him, a human version of him, who was going to stay.
"Alright, both of you answer me this- when I last stood on this beach on the worst day of my life, what was the last thing you said to me?" Rose stared at her Doctor, "Go on. Say it."
"I said "Rose Tyler"." The Doctor answered back.
"Yeah, and how was that sentence going to end?" Rose needed to hear him say it at least once.
"Does it need saying?"
Rose just stared at him. He couldn't be serious.
"And you, Doctor?" She turned to the copy, "What was the end of that sentence?"
The clone reached for Rose's arm and leaned in to her ear.
"I love you." he said, "So, so much."
As he leaned back Rose gazed at him, trying to soak it all in. All those years, waiting for confirmation, and there it was. She couldn't hold back. She grabbed his collar and pulled him to her. Passion washed over them. The wall they had created in those months of being together, always keeping their emotions in check, never wanting to push the other too far, came crashing down in that moment.
Rose heard the TARDIS door close. She spun, breaking her grasp on the Doctor and running after the disappearing time machine. But it was too late, they were gone. The Doctor, Donna, and the TARDIS closed off in their own dimension.
Rose felt the Doctor come up beside her and take her hand. They looked at each other and a wave of realization washed over Rose. Her Doctor, the Doctor that she had spent years trying to get back to, was now gone. Again. This man standing beside her, he wasn't the Doctor, he was just a copy.
Rose shook off his hand and glared at him, remorse, disgust, and resentment all boiling up inside her. This Doctor wasn't the one she had traveled with. He knew nothing of the first hand conversations Rose and her Doctor had shared late at night in the TARDIS, or of all the exploring they had done on alien planets, saving the lives of millions.
She stood there, devastated. How could her Doctor have done this to her, left her here with a man who claimed to be the person she loved?
"I'm going to call dad now." Jackie called over to them.
Rose just kept her gaze on the Doctor.
"Rose..." He tried to gauge where all this was coming from.
"No." Rose held up her hand, "Just... Don't speak. I don't know who you think you are, but you're not my Doctor."
The Doctor didn't know what to do, so he just stood there, staring at the woman he adored, heartbroken by her words.
Rose saw sadness glaze over his eyes and instantly felt guilty, but not guilty enough to change her mind. She turned her head away from him. She couldn't even look at him without feeling overwhelming misery.
The drive home was silent. Rose sat on one side of the car, the Doctor on the other. The tension in the air was so palpable that not even Jackie dared to utter a word. When they got back to the house, Rose slid out of the car and walked to her room, not making a noise the entire time. Once she was in her room, she slumped down on to her bed. What was she supposed to do? Here she was, stuck with someone who looked just like her Doctor, who acted just like her Doctor, but who wasn't him. She had spent years trying to get back to him, and now he was just… gone.
Rose curled up in the middle of her bed, trying to clear her mind. She kept hoping that this was all just a dream, that in the morning she would wake up back in the TARDIS and be on her way to seeing the real Doctor.
