A/n: This chapter is a bit longer. Just to let you all know, this story takes place after "The Idiots Lantern" for the Tenth Doctor, and it takes place after "Vampires in Venice" for the Eleventh Doctor. The Tenth Doctor has not met Martha yet, or Donna, and Rory and Amy aren't married yet. :) Enjoy and please comment. Sorry for grammar mistakes.
"Oh, it's beautiful!" Rose Tyler exclaimed to the Doctor, as she stepped out of the Tardis. The wind blew her short hair back and she smiled at the scenery. She hadn't been to many beaches in her life, and the ones she had been to were always dirty. But this beach was another story. The rock formations created a wonderland for Rose. And the water was so clear that Rose was mystified. The Doctor stepped out beside her.
"It's alright." He said, shrugging.
Rose scoffed and looked over at him. He smiled cheekily at her. "Just joking." he said.
"You better be." She replied, bumping her shoulder into his.
He simply laughed and grabbed her hand before pulling her with him toward the majestic water. Just as the Doctor was about to run into the water, she pulled her hand out of his. He turned back toward her. "Aren't you coming in?" He asked, his hair wild from the wind.
"I'm not wearing proper clothes." Rose said, gesturing to her jeans and sweater.
"Well, that never stopped me." The Doctor said, his smile never fading as he shrugged off his converse, before diving into the water.
Rose laughed, watching him as his head popped out of the water. "C'MON!" He exclaimed.
Smiling, Rose pointed back to the Tardis. "I'm going to go change." She said.
"Hurry!" He replied, diving back down into the water, chasing a school of fish.
Rose laughed and ran toward the Tardis. Rushing inside, it seemed to greet her with like a lost companion. She stopped short. It looked different. Weirder. Bigger.
Curiosity getting the best of her, she began walking down a random hall before picking a random door and pushing it open. "He's got a swimming pool?" She murmured out loud. She took a step into the room and raised her eyebrows. "He's got a swimming pool, in the library?" She muttered, before bursting into laughter.
"AMY! RORY! WHERE ARE YOU?" an unfamiliar voice called out.
Rose looked around, eyes wide. Someone had gotten into the Tardis! Quickly, she found the most threatening thing she could find, which happened to be a fishing net, and began her way back up the hall. A strange man was running around the Tardis. Hesitantly, Rose called out, "Who are you?"
He stopped running and looked at her. His expression turned from panic to a pure blank stare. "How are yo- what are you doin-" He stopped and rubbed his eyes.
"Tell me who you are." Rose said.
He simply stared at her.
"I'm warning you!" Rose said, "I've got a net and I'm not afraid to use it."
His lips twitched, before he broke out into a smile. "A net?" He asked.
"A net! A big one." She said. "Now I demand you tell me who you are right now!"
The stranger straightened his bow-tie. "I'm the Doctor." he said.
Rose scoffed. "I know the Doctor. You're most definitely not the Doctor." She muttered.
"Rose-"
"How do you know my name?" Rose exclaimed, threatening him with the fish net.
He put his hands in the air as a surrender motion. "Calm down and think. You knew me when I wore a leather jacket and when I wore a suit. I changed my face. I regenerated. I'm my eleventh regeneration." he said in a calm voice.
Rose swallowed. "How am I supposed to believe you?" She asked. "You could be lying to me."
"Because I know you." The man said. "Rose Tyler, daughter of Jackie and Pete Tyler. Ex-boyfriend, Mickey Smith-"
"What do you mean ex?" Rose exclaimed.
The man's eyes widened. "Whoops." he said. "Not that far yet, eh?"
Rose was beginning to panic. She held up the net and began to make her way toward the Tardis doors. Facing the man who called himself the Doctor, she opened the door before sprinting out. He wasn't far behind her.
"DOCTOR!" She exclaimed.
There was no reply, just the sound of footsteps of the stranger in the bow-tie behind her. "Ros-"
"DOCTOR! DOCTOR, WHERE ARE YOU?" She said, before taking out in a sprint. She ran up and down the beach, ran into the water, and swam as far as she could, but she couldn't find him. He was gone.
When she returned to the Tardis, the man in the bow-tie was standing there with a towel. He offered it to her, and she took it after a moment of hesitation. He sat down on the sand and patted the spot next to him.
Swallowing down her emotions, she sat down beside him. "So, where's the Doctor, my Doctor, I mean." She asked.
He looked at her. "I don't know yet." he said.
"But you'd have to know. It would be your past!" Rose exclaimed, fury leaking out. All she wanted was the Doctor. Her Doctor.
"No. It doesn't have to be. We're rewriting the course of history. Changing the laws of time." He said.
"What do you mean?" Rose asked sharply.
The Doctor, if that was who he was, swallowed. "I believe, that right now, on this very day, I've crossed my own time-stream, and by doing that, I've changed it." He said, looking down.
"How did I end up here with you?" Rose asked, her voice calmer.
"Well, there are cracks... cracks in time. Some lead to parallel worlds while others lead into complete nothingness. When the cracks open, if you are pulled in, you could be put anywhere, any time frame, any place." He said.
Rose concentrated on his face. "You really are the Doctor." She said.
He nodded, looking up and meeting her eyes. "I am." he said.
She swallowed and shifted her gaze to the water. "If you're the Doctor, where am I?" she asked. "Who were those people you were looking for? Jamie... Kari..."
"Amy." He said, cutting her off. "Amy and Rory. They're my friends." he said.
"I was your friend. Where am I?" She asked.
He swallowed. "I can't tell you... but you're safe, with a man you love." He said.
Rose nodded. She took that moment to study him. He was slim, just like her Doctor. His hair was a floppy mop which could stand a bit of ruffling. He wore a nice button down shirt, tucked into black pants that stopped an inch short of his ankle. His shoes were laced-up, black boots, and Rose decided they complimented him nicely. Over his shirt, he wore red braces and a tweed jacket.
Then, she noticed his bow tie.
"A bow tie?" She asked, and couldn't stop the smile that spread across her face.
He looked over at her and smiled a bit. Straightening it, he said, "I like bow ties, bow ties are cool."
