A/N: It's gonna be switching from third person to first person POV, because it felt wrong to just plop the Doctor in with no explaination. Please don't hate me for starting with 11 and Amy, I just needed to have a Doctor who already knew her, and I want the majority of the story to be with 10. (It's my first real story, please go a bit easy on me!)

"So, um, crash of the Byzantium. Have we done that yet? ... Obviously ringing no bells. Right, um - oh, picnic at Asgard. Have we done Asgard yet? ... Obviously not. Blimey, very early days, then. Hoo! Life with a time traveler - never knew it could be *such* hard work." ~River Song, Silence in the Library

Age 6

"Come on, kid, can we just stop for a minute?" Cameron moaned and grabbed my hood as she stopped. I glared up at her.

"No! I wanna go on the swings!" I grabbed her hand and pulled with all my weight. My sneakers left little ditches as a pushed off and fell.

"Can we walk then?" God, she was so lazy. If I could run four blocks and still have breath, why couldn't she?

"Never!" I exclaimed and hauled myself off the ground, running away from my sister at top speed.

"Krista! Get back here!" She rolled her eyes and chased after me.

"Last one to the swings is a rotten egg!"

The Doctor glanced at his companion with a grin.

"Where are we?" Amy asked.

"I set the TARDIS for a Magical Mystery Tour. Go check it out." He held the door open for his newest companion.

Amy glanced out. "We're in a park. A park, full of little kids, and one of them is staring at me." The Doctor looked around the playground. He spotted a little brunette girl looking at the TARDIS with curiosity. A young woman snuck up behind the child and scooped her up into her arms.

"God, kiddo, you scared the crap out of me!" The teenager said as she tickled the squirming child.

"Cammie, Mommy said you're not allowed to say crap in front of me, because I'll start saying it, too."

Cameron rolled her eyes. "Come on, I'll go push you. You still want to go on the swings, right?"

"But, look! They came out of the box!" Krista pointed at the TARDIS with a look at her sister. Cameron smiled at her sister. She came up with the cutest things sometimes.

"Who did?" Cameron played along.

The child pointed at Amy and then the Doctor. "The girl! Then the floppy hair man came out!"

"The floppy hair man? What does floppy hair look like?" Cameron enjoyed Krista's crazy stories much more than pushing her on a swing. Krista put her hair in front of her face and made a 'pft' sound. Cameron smiled.

"And where is Mr. Floppy Hair Man?"

"Right there!" Krista ran towards the Doctor. Cameron reached out to grab her, and caught a handful of air. She hadn't meant for Krista to disturb them. She wouldn't like it very much if she was being called 'Rainbow Hair Girl' by a little kid, and she guessed neither would the man. Cameron ran after her little sister.

"See?" asked Krista when Cameron caught up to her. "He has floppy hair!"

"I'm sorry," Cameron apologised to the Doctor, "She thinks you came out of the blue box. I'm really sorry about this." The Doctor remembered something, something from a long time ago, in his last regeneration. One of his companions had mentioned...no, it couldn't...could it? She'd mentioned first seeing him when she was a child. She said he had floppy hair, and that she'd never seen that Doctor ever again. Could the little girl standing right next to him be one of his companions? He had to be sure.

Cameron took Krista's hand and started to walk away.

"Wait!" Cameron spun around at the Doctor's voice. "I didn't catch your name. What was it?"

Cameron looked at the Doctor. Why did he want to know her name? "I don't see why you would care."

Krista held out her hand. "My name's Krista. Krista Blaire."

"Oh, nice to meet you, Krista Blaire! I'm the Doctor, and this is Amy," he looked at Amy, "Go ahead, Amy, say hello to Krista." Amy looked at him questioningly, and turned to Krista.

"Hello, Krista. I'm Amy." Krista grinned.

"That's Cammie. She's a little crazy sometimes," she pointed to her sister. Cameron's jaw dropped.

"That's enough! Come on, Krista, Mom'll be worried if we don't get home soon."

"But we just got here!" Krista whined, "And I'm talking to The Doctor!"

"Oh, I'm sure The Doctor wouldn't mind if we left. Come on, Krista." Cameron was alarmed by the man's sudden friendliness. She picked Krista up and started to walked away, ignoring her sister's protests and squirming.

"Cammie! Put me down! PUT ME DOWN!"

"PUT ME DOWN!" I screamed at my annoying sister, and I bit her arm. Her grip loosened, and I jumped out of her grasp. I pretended to cry, and Cammie froze.

"Are you alright?" I showed her my knee, which I had skinned as I landed. "Oh my God, I'm gonna get Mom, stay there!" As I watched her run away, I slowly got up, and went back the way we'd come. I wanted to see that blue box again.

"Come on, Krista." Cameron picked her sister up, and walked away from the Doctor.

"Amy, we've got to go." The Doctor looked at his companion.

"Is it because of the little girl? Is she an alien?"

"No...I knew her," Amy glanced at him. "I'll explain when we're in the TARDIS." They walked back to the time machine and went inside.

Amy crossed her arms and leaned against a railing. "Who is she?"

The Doctor ran a hand through his hair. "Amy, you remember when I came back for you. On the roof? The Atraxi?"

"Yeah, the big eye thing."

"You remember the men on the hologram?"

"Yeah, after you asked if Earth was protected, it was only last week, Doctor, I can remember it just fine."

"Those men were me. Do you remember the last man?"

Amy was only slightly surprised. After what she'd seen, she'd believe anything. She'd ask more about it later, when the Doctor was in less of a rush. She nodded.

"Krista used to travel with me when I looked like that. She told me that the first time she met me, I had floppy hair, and there was a girl with me."

"Which would be me."

"Yes. And I'll tell you more later because she'll be here in a moment." Right on cue, there was a knock on the door.

I knocked on the door of the box, feeling quite silly. The door opened, and the Doctor looked out.

"Krista! Hello, what're you doing here? Where's your sister?"

"Cammie went home to get Mommy because I fell."

"She just left you here? Well, that wasn't very good! Come in!" I grinned and stepped inside. I gasped.

"What's this? It's so pretty!"

"This is my spaceship." The Doctor smiled at me.

"It's a spaceship?"

The Doctor nodded.

"Are you an alien?"

The Doctor nodded again.

"Is she alien, too?" I looked at Amy.

"No, she's human." Amy waved slightly.

The door opened. "Krista..." Cameron trailed off as she took in her surroundings. "Krista! Are you alright? What has he done? Did he give you anything?" I stared at her.

"Cammie! He's an alien! This is his spaceship!"

She grabbed my hand and pulled me away from the Doctor and towards the door. "You-You lot, you're crazy, you are. You don't talk to her ever again, you got that? Stay away from my sister." She pointed at the Doctor.

"Cammie, it's okay!"

"Shush." Cameron picked me up and walked backwards until she hit the door. She opened it, and stepped back onto the grass. She put me down and grabbed my hand, starting to run. There was a sound from behind us, and I wiggled out of her grasp. I stared at the box, which was making the Vwroop, vwroop sound, and it disappeared, the leaves that were near it blowing slightly.

"Come on, Krista, we're going home." I turned my back on the now empty spot, and sadly walked away.
