The Doctor and Donna walked along the New Parisian streets, the sun shining bright above them. They each carried a pastry, and Donna took in the sights and smells. It was nearly identical to the Paris she knew, only this one was futuristic. Her eyes locked onto one particular being that acted in a very abnormal way compared to how it would act on Earth.
"Doctor, that's a cat," she whispered, nudging the Time Lord.
"Oh, the Catkinds!" he said cheerily. "Don't point, Donna, it's rude."
"But it's a giant cat!"
"No, they're like cats, but they aren't cats. They're the Catkinds. They can talk and eat and walk just like us."
"It's wearing clothes!"
"And so are you! What's the big deal?"
"Nothing, I guess. Oh wow!" They were now in front of the Eiffel Tower. Donna felt a wave of awe rush over her.
"That's the same Eiffel Tower," the Doctor explained. "All these years, and it's still in one piece."
"That's incredible," Donna said softly. "So, let me make sure I'm getting this, when my planet dies, people just move here instead?"
The Doctor nodded. "Yep!"
Donna took a bite out of her pastry and chewed quietly. "But what about the others?"
She felt the Doctor's gaze upon her. "What others?"
"The other people who lived here," she said, turning her head to face him. "There were others here before, right?"
The Doctor shifted his shoulders and looked ahead. "Yeah, I suppose there were."
"Doctor-"
"Look, what's happened has happened. We can't change it."
"But why can't we?"
"Because it's a fixed point in time, Donna. You know these things."
"Do I?" Donna felt the ground shake beneath her feet. "What was that?" She looked up and felt incredibly dizzy. "Doctor?"
The Doctor's face was haunting. "Donna, I'm sorry. I'm so sorry."
"Doctor, what's happening? You tell me what is happening right now! I deserve to know."
The ground shook again.
"Doctor?"
"Donna, sweetie, are you alright?"
Donna opened her eyes, shutting them quickly to block out the light.
"Donna?"
She opened one eye, and then the next. Her grandfather was sitting on her bed, a concerned look etched upon his face. "What are you doing in here?"
"You were screaming in your sleep, dearie," he answered. "Is everything okay?"
"Everything's fine, I was just having a dream."
"Not a nightmare?"
Donna thought hard. The man with the untidy brown hair and blue suit was already slipping away from her. "No. I think it was just a dream."
