Disclaimer: I do not own Doctor Who.

A/N: Okay, so I'm having some major family issues right now so I haven't been able to write anything for a while so I thought I'd just post this short little ten chapter story that I wrote a while back but never updated. I'll update it once every week and hopefully before the end of this I'll be back to writing for my other stories, I'm really sorry but I don't know how long it will take to resolve the issues. Hopefully, all will go well.

Enjoy!

Clara was fed up. No, she was more than that. This Doctor was grouchy, yelling at her all the time. Sure, there were a few times when he seemed to need her support, but he could be so stubborn and, well, rude. She sighed. Of course, it could just be the fact that he had regenerated from the craziest man she's ever met. He was looking at her expectantly. Had he been talking?

"Um, what?" She asked. He looked at her like she just dribbled on her shirt.

"I was saying, Clara," he added more emphasis on her name, "I think we should go to Argo, lots of different things to do this time of year." Clara raised her eyebrow at the 'this time of year' comment. They were in a time-and-spaceship, why did it matter what time of the year it was? Oh well.

"Sure, but what is Argo?" She questioned. He looked to her with a slight smile on his face like he was expecting her to ask that.

"A small planet that becomes a major trading port in the early 62nd century." He explained, typing the coordinates into the TARDIS.

"Interesting." Clara drawled for lack of anything better to say. Personally, she was hoping it could be more of a spa planet but she highly doubted the Doctor would take her to one, especially this regeneration. He didn't reply, choosing to walk to the door instead. Clara sighed again and followed him to the door. They walked out onto a crowded street, her ears instantly insulted with the yells of buyers and sellers. The streets were lined with a plethora of shops. Some of the shops sold items she easily recognized, others had nothing she could identify. The Doctor slipped into the throng of people, not even bothering to warn Clara. She followed him into the crowd, keeping her eyes on the red lining of his outfit. He was pushing his way through the crowd, leaving her to slip behind him as best she could. She received several glares and more than a few threats from some of the people she had pushed through. When they finally made it through the crowd, she turned on the Doctor. "Did you really have to push through them?" She grumbled.

"It doesn't matter." He replied. His eyes were staying trained on something in the distance she couldn't see.

"What are you looking at?" She finally asked when she couldn't hold it in. His eyes snapped to her.

"I think I just found somebody who could use our help." He said before taking off running at a surprising speed. Clara followed him, dodging large groups of people. The Doctor navigated through the streets relatively well, his eyes still focused on something that seemed to be just out of her eyesight. He led her to an alley filled with fog so thick she could barely see her own hands.

"Doctor?" Clara questioned. He frowned at her.

"Quiet." She stayed silent for a minute, waiting to hear something. Nothing could be heard except for the distant noise of chattering from the stalls.

"I don't-" She was interrupted by a yell in the distance.

"What the hell do you want?" The voice echoed. The Doctor looked to Clara before taking a sharp right further into the alley. Clara followed closely behind him looking for the source of the noise. Three figures slowly came into view, starting as a shadow but becoming more detailed as they got closer. As far as Clara could tell, it was a girl with two guys on either side of her. As they got closer, Clara could make more out. The girl looked to be just over five feet with straight, brown hair and defiant, chocolate eyes. Something about her was almost familiar to the Doctor. What was it about her? She appeared to be glaring at the men, refusing to back down. Two taller men, six foot at least, were on either side of her. The one closest had his reptilian arms crossed over his muscular chest. The other seemed to be in more of an aggressive stance with sharp, yellow teeth barred out at her.

"Give it back." The closer one stated with a calm demeanor. The Doctor took a menacing step forward, revealing himself through the fog.

"Leave the girl alone." He said calmly. The three turned towards the Doctor.

"She stole from us, nobody just gets away with that." The man spat.

"Anyone with half a brain could get away from you." The Doctor replied. The man growled ominously at the Doctor who didn't even flinch.

"Nobody." The man restated.

"No, pretty sure he's right." The girl said in a smooth American accent. "It doesn't take much to get away from you guys." The Doctor looked to her with a raised brow.

"Says the one who got caught." He contradicted. She smirked at him.

"I only get caught when I want to." She replied. Again, something extremely familiar. It's right there. He knows her, or somebody like her from somewhere. She almost reminds him of… oh but no. That's not right.

"What could possibly make you want to get caught?" Clara couldn't help but ask. She shrugged.

"I wanted to know where the factory is. It would be easiest just to get thrown in its jail." One of the men sneered at her.

"Factory?" Clara asked. The girl looked to the two men next to her who weren't speaking but already in an offensive stance.

"They have the last vortex manipulator available at this time." She replied. The Doctor looked to them, surprised. Vortex manipulators should have been entirely impossible to find in the 62nd century. "And it seems," the girl began, holding a damaged vortex manipulator, "that some things just don't come back from a laser blaster."

"Aren't you a little too young to be a Time Agent?" The Doctor spoke with evident disgust at the thought.

"Aren't you a little too old to be stopping fights in an alley?" She replied. Clara bit her lip from laughing at the girl who just insulted the Doctor. He looked completely taken aback, not expecting her to reply like that.

"Never too old for that." He replied. She smirked at him.

"Whatever you say, pops." She gave a mock salute and looked to the creatures in front of her. "Are you two going to arrest me or are you going to watch all day?"

"Why arrest you when we could just kill you?" The closest replied. The girl's eyes widened and she let out a nervous chuckle.

"Right, didn't exactly think about that." She looked apprehensively at Clara and the Doctor, wracking her brain for an escape plan. The reptilian like alien closest to her pulled out a gun at the same time the Doctor pulled out his sonic screwdriver. A soft whirring emitted from his device and the gun sparked in the alien's hand. He pulled the girl in front of him.

"Run!" He yelled. Clara, the Doctor, and the girl were running before the alien's had even processed what happened. Clarity hit them like a bullet and they took off after the three who they'd been threatening only moments ago.

"Follow me!" The girl exclaimed to the Doctor and Clara. "I know a shortcut." She took a sharp left into a darkened alley. The sounds of the marketplace were growing by the second, drowning out the yells of the aliens who were still giving chase. They were far enough away that they could lose them with just the right movements. Just before they entered the overcrowded streets, she pulled the Doctor and Clara to the right and up a steep flight of steps. Upon reaching the top, she pushed them into a window of what appeared to be an abandoned shop. "Down the stairs." She informed the Doctor. He and Clara went down three flights of stairs, stopping at a locked door. The Doctor pulled out his sonic screwdriver again fully intent on opening the door. "I don't think that sonic screwdriver will do much good to a deadbolt." He looked at her curiously, very few people ever knew what a sonic screwdriver was, let alone what it was capable of. She pulled a chain from under her shirt and held up one of the many objects on it, which happened to be a key. She swiftly unlocked the door and held it open for both Clara and the Doctor. They entered rather hesitantly. "Oh come now, do I really look like the kind of person who will murder you?" She asked, closing the door and locking it behind them. The Doctor and Clara inspected the mess of papers pinned to the wall indicating different time periods and places.

"This doesn't exactly strike me as normal child behavior." The Doctor grumbled, indicating her mess of papers.

"That's," she paused and let out a heavy sigh, "nothing. It's useless."

"But it wasn't intended to be." He turned back to the brunette. "So what was it intended for? And why exactly did you want to get the vortex manipulator? I'll tell you why, because you're looking for someone! So who are you looking for exactly?" He questioned her. She raised a single brow at him.

"That is none of your business." She replied rather defensively.

"We might be able to help." Clara suggested. The Doctor shot her a look.

"That depends entirely on who you're looking for." The Doctor said. "If you're looking to murder somebody, sorry can't help there." She shook her head, the ghost of a smile on her lips.

"No, I'm not looking to kill anyone. It should be okay to leave now, just stick to the streets until you're ready to leave." The girl said.

"You never did say what you stole." The Doctor prompted. She laughed quietly.

"Oh nothing very important just a few telecom devices and a long range teleport." She replied.

"Any particular reason why you chose to steal those items?" He asked her. She shook her head.

"It was that or some of their weapons and I prefer to stay away from guns, thanks." He gave her a genuine smile.

"Smart girl, don't you think, Clara?" Clara smiled to him.

"Just brilliant."

"I do think now that it's quite safe and it's about time I got this troublemaker back home." He said as a way of goodbye, moving closer to the door.

"It was nice meeting you!" Clara said. She smiled to them.

"Yeah, see you around." She responded quietly. The Doctor and Clara unlocked the door and walked out silently. The Doctor stopped and spun around almost as if he just remembered something.

"I forgot to ask, what's your name?" She looked to him with a quirked brow.

"Alena, why?" She asked. He just shook his head.

"Hello, Alena, I'm the Doctor." He said before moving to exit. Alena's eyes widened and her breathing stopped.

"What?" She whispered almost inaudibly. She spoke so quietly that Clara couldn't hear but the Doctor could. He turned back into the room, taking note of the clear shock written on her face.

"Doctor?" Clara asked. She followed him back into the room, looking from the girl to the Doctor.

"I take it you've heard of me?" The Doctor asked her. She looked up at him with wide, innocent eyes. The sense of familiarity screamed at the Doctor again.

"The Doctor? As in the Doctor with the TARDIS? As in the Doctor with the TARDIS from Gallifrey? As in the Doctor with the TARDIS from Gallifrey that's a T-"

"Yes!" The Doctor interrupted rather grouchily. "That Doctor." She looked at him, her surprise still shining in her eyes but there was something else, hope? Fear? He couldn't tell.

"No way." She breathed more to herself than anyone else. "How… what… but I wasn't even… what?"

"Oh, just spit it out already." The Doctor said frustrated. The way she was talking and the look of her eyes seemed so eerily familiar.

"M-my mom." She whispered shakily. Clara noticed the telltale sign of tears in her eyes and dropped down to comfort the young girl.

"Yes, I'm sure she's a wonderful lady." The Doctor snapped. Clara glared at him.

"That's who I'm looking for." She continued, almost oblivious to what he was saying.

"Well that's lovely but what's this got to do with me?" He asked anxiously. Clara shot him another look, rubbing the young girls back in soothing circles.

"My name is um…" She looked up to him with meaningful eyes, "My name is Alena Kassandra Tyler." The Doctor's world froze. Not the kind of freezing where everything come to stop slowly, all processes and functions just slowly dying out. No this was the kind of freeze where everything stops in an instant. His thoughts came crashing down making the connection to why she was so familiar. The big brown eyes, the ability to think quickly, the straight brown hair, how had he not thought of this earlier? This, this girl, she was Rose Tyler's daughter! And apparently she was looking for Rose Tyler herself! Clara noticed the look of pure shock on the Doctor's face. This had something to do with his past apparently.

"Tyler." The Doctor repeated softly. "The daughter of Rose Tyler." He stated matter-of-factly. She nodded slowly. "And," his voice wouldn't allow him to continue.

"And John Tyler." She finished for him. She laughed nervously, "I guess that makes you my father too."

A/N: Okay, there's chapter one, chapter two will be up next week. Not going to lie, I cried writing a few chapters of this. I hope you all like where this story is going to go. I promise it gets better and it actually gets really sad. I thought Twelve was the perfect Doctor for this story simply because he seems so adamant about not letting anyone break down his emotional barriers. So yeah, this will get kind of angsty. Anyways, I hope you liked it and I'll see you next week.
