PART ONE- THE TIME LORD
The familiar sound of the TARDIS landing fills the console room, but does nothing to rid the Doctor's face of the seemingly-permanent frown etched upon his countenance. River hit some buttons and pulled some levers, and the sound stopped. She knew how to fly it properly, without any noise, but she thought that maybe the sound would cheer him up.
Two weeks of normal time had passed inside the TARDIS since the Doctor had watched his best friend disappear into a time he could never visit. Of course, in the course of those two weeks, the Doctor and River Song had traveled to many planets and met many new friends, and foes.
"Sweetie, we're here," River said, donning on a red sundress, a small handbag, a rather large hat, and a pair of overpriced sunglasses she had expertly swiped from a department store that was 60 years in the future. "Sebastian, Florida, 1953."
The Doctor nodded, not even taking the time to complain about the ridiculous ensemble River had made him wear instead of his usual clothes (it included surprisingly tight swim trunks and a sailor hat). He blinked furiously as they stepped from the Console Room out into the bright and warm Florida sun.
As they walked along the beautiful town of Sebastian, River took out a slip of paper with a name on it, Ferndal, and an address. It was a lodge right on the beach that she had found and wanted to stay at. As lost and lonely as the Doctor was without the Ponds, he still wanted to make River happy whenever he could, so whenever she asked for something such as a vacation, he always gave in.
As they came to the lodge, the pair passed by a young girl of about seven with jet black hair wearing a white dress and holding a red balloon. She stared at them as they passed, and began to follow them, not taking her eyes off of the back of the Time Lord's head. River and the Doctor communicated through some sideways glasses, indicating that they had both noticed the suspicious behavior and were currently running through every species they knew as they glanced back to survey their pursuer.
The little girl had stopped a few feet back and had let the balloon go. She was staring straight at the Doctor. He immediately felt something in his gut, something very, very not good.
"River," he whispered, "what are the chances that you have your blaster with you at this very moment?"
His companion smiled, and whispered back, "Do you really have to ask, sweetie?" as she took the sonic blaster from her handbag, discreetly hiding it behind her back, with her finger on the trigger. The Doctor took his screwdriver from the pocket of his shirt and slowly approached the girl, who had begun to smile slightly.
"Hello, miss," the Doctor said quietly as he got down on one knee to be at her level. "Are you okay?"
She tilted her head to the side and said with a sickeningly sweet and innocent voice, "Yes, sir. I just couldn't help to notice that your girlfriend is very pretty." She was now staring at River, whom the Doctor could sense tensing up and pushing down slightly on the trigger of the blaster. The young girl turned on one foot and walked away without another word.
The Doctor and River shared a confused look, sure that the danger wasn't over, but ready to forget it happened and have a nice lunch. They continued into the Lodge and checked in, not even slightly aware of what was about to happen in the town of Sebastian.
