SUMMARY: What if Rose had a cousin? What if she was there when the alien ship landed in London? What if Rose's cousin wasn't human?

This will be a Doctor/Oc story, Rose will not be a jealous girl but a, well, you'll see. *Sneaky smirk*

I do NOT own Doctor who! Only my Oc's and story idea!

EARTH, LONDON

TYLER FLAT

Jackie sighs as she sat in the living room of her home, it has been 11 months since her daughter Rose had vanished into thin air! Her boyfriend Mickey had almost been charged with murder until no evidence was found and he passed a lie detector test, it was a big relief for Jackie knowing that Mickey was innocent but she was still worried about her daughter!

Jackie huffed she was about to get up and make herself a drink when a knock on the door made her jump, getting up she went over saying "Coming!"

She unlocked the door and opened it only to gasp in surprise at who was standing at her door!

"Hello, Aunt Jackie!" A smooth female voice said.

Said voice belonged to a young lady around the age of 24 with shoulder length brown hair and light blue eyes with golden freckles around her pupils, she had a runner build with a toned form from running and gymnastics. She had on a nice outfit of a brown top with blue jeans, brown shoes, and purple jacket and was currently holding a suitcase, she smiled at Jackie's reaction to her arrival.

"Jane Tyler! I didn't know you were coming!" Jackie said hugging her adopted niece.

Jane smiles using one arm to hug her back, you see, Jane was not a Tyler by birth rather she had been adopted after being found by Peter's brother and his wife. She had been found in a park all alone with torn clothing and a strange watch that she always kept with her, at the time Peter's brother Samual and his wife Louise were going to adopt a child since Louise was unable to have children due to being sterile.

So, after finding and rescuing, at the time 13-year-old girl, they decided to adopt her as their own and since then Jane has been apart of the Tyler family. She got on really well with her at the time 8-year-old cousin Rose who loved her to bits, Rose would often hang out with Jane while they lived in England always doing stuff together like sisters. Then she had to move away when Samual got a job in America, the two kept in touch which is why she was here now.

"I'm glad to see you, Jackie, has there been any sign of Rose?" Jane asked a little bit worried.

"No, it's terrible not one person has seen her in the last 11 months," Jackie said as she let Jane inside.

Jane set her suitcase down a frown on her face, she had recently lost her parents in a car crash thanks to a drunk driver who was now behind bars. She did not want to lose Rose too!

"We'll find her, I'm sure of it," Jane said as she hugged her aunt again.

"I heard about what happened to Samual and Louise," Jackie said making Jane hug her tighter.

"It was quick Jackie, I'm just glad that...they didn't feel any pain," Jane said her voice cracking slightly.

Jackie pulled back to see unshed tears in Jane's eyes making her give a sad smile saying "Come on, let's have a nice cup of tea and chat, better to talk about the happy times then reflect on the bad,"

Jane nods saying "Sure, you always know what to do Auntie,"

"I sure do," Jackie said as Jane picked up her suitcase and went to the guest room to sort things out while Jackie went to make some tea.

Jane smiled as she put her suitcase on the bed while looking around the clean room, she had so many fond memories of this place. Reaching into her pocket she pulled out her most precious item. A gray fob watch with strange symbols on it, for as long as she could remember this had always been with her. While it was broken she always had this urge to open it but...she didn't feel ready for some reason like there was something she needed to do first to open it.

Sighing she put it back in her pocket and went to unpack, she was looking forward to spending some time with her Aunt.

A MONTH LATER

Jane hummed as she sat in her room reading a book while listening to music, which was classical music, while Jackie was in the living room watching TV.

'Another month and still no sign of Rose, where could she be?' Jane thought as she narrowed her eyes at her book as it got to the good part.

Jane was about to turn the page when she heard the door open followed by someone talking, sitting up she put her book down and turn her music off. She tried to listen in when the sound of something breaking made Jane jump up and out of the room.

"Jackie! What's wro-ROSE!?" Jane yelled as she ran into the room to see standing there in the flesh was Rose! Her missing cousin!

"J-Jane? W-when did get here?" Rose asked in surprise while Jane rushed forward and hugged her.

"You've been gone for 12 months! Where the bloody hell were you?!" Jane asked as she pulled back letting Jackie hug her daughter.

Before Rose could answer them a man came through the door panting slightly, Jane narrowed her eyes at him.

"It's not twelve hours, it's er...you've been gone a whole month, sorry," He said giving a nervous laugh.

Jane crossed her arms as Jackie called in a policeman, soon they were sitting down. Well, Rose was sat down opposite the Policeman while Jackie was standing up as Jane kept an eye on the strange man with a mean glare that was surprisingly keeping him in place.

'I'm watching you...mister cousin stealer!' Jane thought as her protective side came out a bit.

Rose bit her lip as she tried not to laugh at the Doctor's situation, she knew Jane was protective and also knew hand to hand combat/martial arts. She had also taken up archery at one point, the last person to bully or hurt Rose ended up in the hospital when Jane visited her in the past. She only hoped Jane didn't hurt the Doctor too badly.

"The hours I've sat here, days and weeks and months, all on my own. I thought you were dead, and where were you? Travelling. What the hell does that mean, traveling? That's no sort of answer, you ask her, she won't tell me, that's all she says. Travelling," Jackie ranted to the policeman.

"That's what I was doing," Rose said with wide eyes.

"When your passport's still in the drawer? It's just one lie after another!" Jackie said as Jane went over and gave Jackie a one arm hug trying to keep her calm.

"I meant to phone, I really did, I just I forgot," Rose tried to explain as Jane let Jackie go who sent her a thankful nod.

"What, for a year? You forgot for a year? And I am left sitting here with Jane, I just don't believe you! Why won't you tell me where you've been?" Jackie said worry lacing her voice.

"Actually, it's my fault, I sort of er, employed Rose as my companion," The man said making Jane look at him.

"When you say companion, is this a sexual relationship?" The Policeman asked making Jane's eyes darken as she glared at the man.

Both him and Rose yelled "NO!" Disgust on both their faces at the thought of it making Jane calm down.

"Then what is it? Because you, you waltz in here all charm and smiles, and the next thing I know, she vanishes off the face of the Earth! How old are you then? Forty? Forty-five? What, did you find her on the Internet? Did you go online and pretend you're a doctor?" Jackie questioned stepping forward to the man.

Jane stepped forward asking "Are you really a Doctor?"

"I AM a Doctor!" He said as Jane growls stepping forward while Rose moved back a bit in her seat knowing what was coming next.

"Well then, prove it mate! stitch this!" Jane yelled before proceeding to slap the 'Doctor' hard across the cheek.

Jackie nodded in an approving way while Rose bit her lip trying not to laugh as the Doctor stumble back a bit holding his now red cheek in pain, that slap hurt! He was suddenly glad the girl didn't punch him, he winced a bit backing up from Jane who looked satisfied.

"That was very refreshing, I am no longer mad," Jane said crossing her arms with a pleased smile.

After a few more minutes talking the Policeman left since no charges were being placed since Rose was now safe and sound back home, Jane stood in the living room with the man simply called 'The Doctor' for some reason it felt familiar to her but she shook it off and ignored her pocket watch which was warm for some reason.

Rose and Jackie were talking in the kitchen as Jane watched the man.

"So, your name is the Doctor?" She asked making him look at her.

"Yep, you?" He asked keeping his distance until he knew she was no longer mad at him.

"Jane Tyler, cousin to Rose Tyler through adoption, so, you and Rose have been traveling? How you been keeping her safe?" Jane asked eyeing him.

"Yes but she likes to get into trouble," The Doctor said rubbing his neck.

Jane nods saying "That's Rose for Ya,"

After a few minutes Jane looked the Doctor over, he didn't seem like a bad guy he just had this edge to him. An edge that made him feel...dangerous yet you felt like you could trust him, he also had a hard look in his eyes that Jane had only seen in soldiers during her medical course. Had he been in a war or lost someone close to him?

She came to a desition after a few minutes thinking it over, if Rose trusted him then she might as well trust him to.

"Since you don't seem like a bad guy I'll let you off the hook," She said with a clapped her hands.

She pushed off the chair she was leaning on and went over to the Doctor and held out her hand saying "Let's start fresh here, I'm Jane Tyler,"

The Doctor watched her carefully he could still feel a faint throb in his cheek from the slap but he didn't want to get on her bad side again, he knew how creative females got when they dish out punishments take Mary I of England or Queen Bloody Mary with her creations.

Reaching over he grabbed and shook hands with her making Jane grin saying "Sorry about the slap, I get protective over Rose at times," Unseen by the Doctor Jane placed a finger on his pulse point and smirked. She was glad to have taken that medical course in college and university.

"So I've figured," He said releasing her hand as he rubbed his cheek.

"By the way," Jane said leaning over. "Care to explain the double beat?"

The Doctor froze at that question, how did she? He looked at her as she smirked before pointing at her wrist where her own pulse point was, what a sneaky female! She used the handshake to check his pulse! Very clever.

"Very clever, but, to answer your question I'm a...well in better terms an alien," He said watching her reaction closely to see how she reacted.

'Holy! He's an alien!...Cool, he's handsome with big ears though' Jane though before grinning saying "Awesome,"

The Doctor smirked feeling oddly pleased with her reaction for some reason, he was beginning to like this human despite the fact that she almost slapped his teeth out.

"Why did you check my pulse point by the way?" The Doctor asked.

"To see if you were healthy or lying about something a force of habit, I'm a nurse took a 4-year medical course," Jane said as she placed a hand on her hip.

"A useful habit I say," The Doctor said he was going to remember that little trick for the future.

Jane smirks as she glanced over to the kitchen to see Rose and Jackie leave the kitchen, it was easy to tell that something was still weighing Rose down so Jane decided to do something about it.

"Alright, you two! With me, were going to the roof!" Jane said as she grabbed the Doctors hand and Rose's.

"What are you doing?" Jackie asked as she watched Jane drag the two out.

"Make sure they don't run off! Again," Jane said over her shoulder making Jackie relax a bit.

POWELL ESTATE ROOF

Jane sat on the stone wall to the Doctor's left while Rose sat to his right while he leaned on the wall, after making Rose sit down Jane had asked her to simply 'talk about her alien trip' which stunned Rose before the flood gates opened.

Rose told her cousin all about the plastic dummies coming to life which is how she met the Doctor, saving him from said plastic creatures then traveling with him. How she saw the end of the world, met a gas creature that could make the dead walk around. Needless to say, Jane felt amazed and slightly jealous.

"No fair! I'm stuck here and you're off traveling through space and time, oh well, that's life I guess," Jane said rubbing her neck with a chuckle.

Rose sighs saying "But Mum, I can't tell her, I can't even begin, she's never going to forgive me and I missed a year, was it good?"

"It was okay," Jane said leaning back on her arms.

"Well, if it's this much trouble, are you going to stay here now?" The Doctor asked glancing at Rose.

"I don't know, I can't do that to her again, though," Rose said fiddling with her hands.

"Well, she's not coming with us," He said making Jane grin.

"No chance!" Rose said with a chuckle.

"I don't do families," He said crossing his arms.

"Just be glad Jane slapped you, my Mum would have added her nails into the mix," Rose said as Jane grinned.

"True, the last person aunt Jackie slapped ended up getting stitches," Jane said remember the said guy who tried to flirt with Jackie.

"Nine hundred years of time and space, and I've never been slapped by someone's cousin," Doctor said while reaching up to rub his cheek.

Jane giggles saying "Your face!"

He turned to her saying "It hurt!" Jane would be lying if she didn't find his whining cute.

"You're so gay! Wait, did you say Nine hundred years old?" Rose asked sharing a look with her cousin who raised an eyebrow in amusement.

"That's my age," He said looking at Rose who smirks.

Jane moved to sit cross-legged saying "You're nine hundred years old? Blimey! That's one hell of an age gap compared to my 24 and Rose's 19,"

Rose sighs jumping down from the wall and walked ahead of them saying "Every conversation with you just goes mental, There's no one else I can talk to except Jane, I've seen all that stuff up there, the size of it, and I can't say a word. Aliens and spaceships and things, and I'm the only person on planet Earth who knows they exist,"

"True," Jane said when a loud horn made her jump.

Spinning around she saw a huge spaceship! Holy cow! "Hit the deck!" She yelled jumping down and crouching behind the wall with the Doctor.

The spaceship flew overhead and over London, Jane stood up watching it fly while small parts dropped off due to the damage it had taken. Jane had to wince as it flew into Big Ben taking a chunk out of it before landing in the River.

"Oh, that's just not fair," Rose said with a gobsmacked look.

"Oh yeah! My first alien spaceship!" Jane said jumping up and down as the Doctor began to laugh grabbing the girls hands and dragging them along.

IN THE STREET

Jane couldn't help the grin on her face as she looked around at the chaos that the ship was causing, the army was already here cutting off access to the river and closing the roads down.

"It's blocked off," Jane said as she looked around.

"We're miles from the center, the city must be grid locked, the whole of London must be closing down," Rose said trying to see past the people and cars.

The Doctor looked very excited saying "I know! I can't believe I'm here to see this, this is fantastic!"

"Did you know this was going to happen?" Jane asked.

"Nope!" Was his answer.

"Do you recognize the ship?" Rose asked while the Doctor smirked.

"Nope," He said.

"Do you know why it crashed?" Rose asked again.

Jane spoke up saying "Let me guess, nope?"

"Correct, I like you, Nurse," Doctor said confusing Jane.

"Nurse?" She asked herself as Rose said "Oh, I'm so glad I've got you,"

"I bet you are, this is what I travel for, Rose. To see history happening right in front of us!" The Doctor said as Jane jumped trying to see over the crowd.

"Well, let's go and see it, never mind the traffic, we've got the Tardis," Rose said unseen by Rose at the mention of the Tardis Jane froze.

'T-Tardis?' Jane thought as a stab of pain hit her head.

Run!...Get g- to the...Tardis!

Use it!...camel-on ar...de-a-e...so..sor-y...my dar-

We...lo-...yo...Lei-...

Jane shook her head as she tried to focus on the event before her. Reaching down put a hand into her jean pocket where her pocket watch was and strangely it was warm.

"Better not, they've already got one spaceship in the middle of London, I don't want to shove another one on top," Doctor said while glancing at Jane from the corner of his eye. He saw her daze off at the mention of the Tardis, he wanted to know why but now was not the time.

"Yeah, but yours looks like a big blue box, no one's going to notice," Rose said as Jane shook her head.

"Uh, Rose? Emergency like this, there'll be all kinds of people watching. Trust me, the Tradis? was it? Stay where ever Doc here parked it," Jane said gensturing to the gathering mass of cars and people.

"Jane's right," Doctor said.

"So history's happening and we're stuck here?" Rose asked before an idea hit her.

Looking at her cousin who also got the same idea as Rose shared a smirk with her and nodded.

"Well, we could always do what everybody else does," Rose said as Jane smirks finishing what Rose was going to say "And watch it on TV!"

The Doctor looked between the two human girls with a bewildered and slightly confused look, the two girls high-five and proceeded to drag the Doctor back home to their flat.
