As anyone who's read most of my other stories probably knows, I've kind of got a thing for Jenny- The Doctor's Daughter, from Doctor Who. To me, she's such an interesting character, with so much untapped potential, and I'm kind of annoyed that they haven't brought her back to the series yet. Even two Doctor's on, it's still possible, as is evident by the return of Sarah Jane. Anyway, as she is one of my favourite characters, I thought I'd write my own accounts of her adventures after she left the planet Messaline. However, I've also developed a liking for crossovers, so she has these adventures inside worlds other than her own. So, then I thought, why not bring her onto a show I've started watching recently, The Librarians, but also bring them onto the Doctor Who episode Stolen Earth at the same time. This is the result of the union of these two ideas. Characterisation may not be spot on for Librarians characters, and Jenny doesn't have that much to draw on, only being in one episode, but I hope you like what I've written.

The alley looked like any other alley. It could have been in any city, on any planet, in any realm. The only thing distinctive about this alley was what was about to happen within it. A fuzzy image began to fade into existence. The fuzzy image coalesced into a well-built young woman. She wore combat trousers and a green t-shirt, and had blonde hair, put into a ponytail. She looked up from the strange, ovular device on her wrist, and looked around, her brow furrowed in confusion. She scanned the top of the buildings that made up the alley. She rummaged in her pocket, bringing out a white envelope, opening it to reveal a sheet of paper. The paper and the envelope were inscribed with golden lettering. The envelope revealed her name to be Jenny Smith, a simple name, but the only one she had.

Jenny Smith was not human, like the inhabitants of the planet she had just landed on. She had emerged fully grown from machine around four Earth years ago. Her father, was the Doctor, and he was her only parent. She had spent the last four years looking for him, but Time Lords are, as she found out, notoriously difficult to track down, especially when the two of you are the last two Time Lords in existence. How this envelope had found her, Jenny wasn't entirely sure. She never stayed in one place more than a few days, always chasing the next lead about her dad, but one day, she had awoken to find the letter, addressed to her, in her room, inviting her for an interview at the Metropolitan Public Library.

It was then, that the second unusual thing happened in the alley. Jenny heard a strange whooshing noise, and immediately shrunk against the wall, as a door right beside her glowed at the edges, and four humans exited. Two male and two female, they didn't immediately notice her, which gave her time to examine them. The older female was blonde, and wore black trousers, and a black jacket, while the younger female wore a brightly coloured dress and had long, red hair. The two males were closer in age, or so it looked to Jenny. The taller male had slicked back brown hair. The younger male had slightly darker skin, and from his posture, Jenny could tell he oozed confidence. Jenny was deciding whether or not to follow them, when the entire Earth jolted, and the sky went dark. Well, not entirely dark, but when it had once been day, it was now dark as night. Having been forced to the ground by the movement, Jenny slowly looked up, to find the older woman with her gun pointed at her.

"Who are you, and why are you following us?" said the woman. Jenny began getting up slowly, putting her hand in her pocket, going for the psychic paper in her pocket "Don't move!" said the woman.

Jenny removed her hand from her pocket.

"Get up. Slowly."

"Eve," said the older man, staring up at the sky "Look at the sky."

The woman, apparently Eve, looked at the sky. Jenny rose to her feet, and looked skywards. Multiple planets were hanging in the sky above them.

"Tell me I'm not the only one seeing this," said the younger woman.
"No, we see it," said Jenny "But I don't believe it." She looked at the woman, who still had her gun on her.

"My name's Jenny, I was following you to ask you where the Metropolitan Public Library is, I got sent a letter inviting me to an interview there. Now, put your gun away before you hurt someone."

All eyes turned to Jenny.

"Show me the letter," said Eve. Jenny pulled the letter, embossed with gold lettering, and handed it to Eve.

"I don't understand. How is this possible" asked Eve, passing it round to the others so they could see it.

"What's not possible?" asked Jenny

"We should talk inside," said Eve "This will be alot to process."

She led the way back through the door they had just come out of, and suddenly, they were somewhere else. They seemed to be in a small library. In-front of them, was a table with various pieces of paper on it, as-well as a globe in the centre of it. An elderly man sat at the table, reading a book, and he looked up, annoyed as the five of them entered.

"Honestly, it's like I don't get a moment of peace in this place," said the old man "You can't possibly have completed your mission already."

"Do you have any idea what just happened, Jenkins?" asked the youngest man. He had a different accent to the others "Just for once, leave your post and look outside."

The man, apparently Jenkins, looked outside at the sky. "Oh my, what have we gotten into this time?"

Jenkins looked over at Jenny "Who is this? Why did you let her into the annex?"

"Name's Jenny," said Jenny "And I've been waiting for ages for someone to explain this."

She pulled out the letter that Eve had given back to her "Everyone here seems to know what it is, and why it's significant, but I have no idea. Who are you people?"

"Ezekiel Jones," said the youngest man, seeming slightly offended that Jenny did not know who he was "World-class thief and entrepreneur."

"Entrepreneur?" asked the second youngest "You wouldn't know an entrepreneur if one was staring you in the face." He held out his hand "Jacob Stone. Academic." Jenny shook it.

"Cassandra Killian," said the red-haired girl, holding out her hand, as-well "Who are you? Why did the library choose you?"

"Surely you know," Jenny shrugged "Didn't you send this to me? And how did you send this to me? This planet hasn't even developed long-distance space travel yet."

"It's complicated," said Eve "But why would we need space travel to send you a letter?"

"It's obvious, isn't it?" said Cassandra "She's not from Earth. She's from somewhere else."

Everyone looked at Cassandra.

"How do you know that?" asked Jenny "I've been on the planet less than five minutes."

Cassandra brought her hands apart, as if she was expanding a motion-activated hologram.

"Soil on your boots is certainly not of earth, small stain on your left trouser leg appears to be blood, smells like blood, but is the wrong colour, also, that device on your wrist is definitely not from this world,"

"Wow," said Jenny "You are certainly observant. Where did you learn that?"

"It's not learned," said Cassandra "I'm a synesthete. I see things that nobody else sees. It's over-whelming sometimes."

"Is that normal on this planet?" asked Jenny "Because that's brilliant."

"Not normal, no," said Cassandra, her eyes downcast "And it comes with a cost."

The girl, who seemed excited just a second ago, now looked sad. Jenny wasn't programmed with instruction about how to deal with people. What she had learned, she had to learn on her own.

"You don't have to tell me if you don't want to, ok?" said Jenny, and Cassandra nodded.

"Everyone here knows," said Cassandra, giving a small smile "I have a tumour that gives me the ability to process information from all five senses at once, but one day it is going to kill me. What day that is, I don't know, so I live everyday like it's my last."

"You are right, of course," said Jenny, electing to change the subject "I am not of this world. I was born on the planet Messaline, a genetically grown soldier, from a tissue sample of my father's DNA. My father is known as the Doctor, and he is of an advanced race known as the Time Lords, who have the ability to travel through time. Beyond that, I've not found much information about them. I've been travelling the universe, looking for my dad, so that I can find out who I am."

A man wearing a suit ran into the room. "Have you seen what's happening outside?"

"Flynn," said Eve "What's going on? Planets have appeared in the sky, and the Library sent out another envelope."

"We're being invaded," said Flynn, putting his hands on his knees, as he panted "I barely got away without them following me. It's an alien invasion out there, how are you not aware of this?"

"We've been kinda distracted by the arrival of an alien in our midst, with a white envelope," said Ezekiel, brandishing the envelope Jenny had left on the table.

"The Library chose her?" asked Flynn "She must have been called to help with this crisis."

Before more speculation could be made of how Jenny was here, they heard a strange beeping noise coming from the clippings book.

"Does it always do that?" asked Jenny, running over to the clippings book.

"This would be the first time," said Flynn, running down the stairs towards the book

"Can anyone hear me?" as the book flipped open. Instead of newspaper clippings, however, as the Librarians were used to, a fuzzy image of a woman was present across the two pages "The subwave network is open, you should be able to hear my voice."

"Who is that?" asked Jacob "What's going on?"

"Captain Jack Harkness, shame on you," said the woman, as her image coalesced. It was a middle aged woman, with short brown hair came on the screen "Now stand to attention, sir."

"Why is this coming through the clippings book?" asked Jenkins "This doesn't make sense."

The woman in the book held up her id, and said: "Harriet Jones, former Prime Minister."

It seemed the woman was having a conversation with someone on the other end of whatever communication this was, but they couldn't hear the other end of the conversation.

"Sarah Jane Smith, 13 Bannerman Road," said Harriet "Are you there? Good. Now let's see if we can talk to each other."

The first screen shrunk, and two other screens appeared, one to the right, and one below, as well as a fourth that was still crackling. The bottom screen showed a woman about the same age as Harriet, and a young boy, while the screen to the right showed three people, two men, one in a suit, one in suspenders, and a woman. A fourth screen on the bottom right was grey.

"The fourth contact is having some trouble getting through,I'll just boost the signal," said Harriet. The fourth screen coalesced into a familiar dark-skinned woman, familiar to Jenny, anyway.

"That's Martha Jones," said Jenny "She was travelling with my dad when I met her."

"Why aren't we getting through?" asked Cassandra "Do we need a webcam?"

"Shh, I want to know why they've been called," said Flynn, waving at Cassandra to be quiet.

"Hello?" asked the woman Jenny had identified as Martha

"Martha Jones," said the man in suspenders, smiling "Martha, where are you?"

"I guess Project Indigo was cleverer than we thought," said Martha "One second I was in Manhattan, and then I ended up in the one place I wanted to be. Home."

Another woman sat down next to Martha "You came home. At the end of the world you came back to me."

"But then all of a sudden," said Martha "It's like the laptop turned itself on?"

"It did," said Harriet "That was me. Harriet Jones, former Prime Minister."

"Yes, I know who you are," said Martha

"I thought it was about time we all met, given the current crisis," said Harriet "Torchwood, this is Sarah-Jane Smith."

"I've been following your work, nice job with the Slitheen," said Jack Harkness

"Yeah, well I've been staying away from you lot," said Sarah-Jane "Too many guns."

"Can we work out where they're broadcasting from?" asked Jenny "They could certainly use our help."

"Well, they've all got British accents," said Stone "Specifically London area, so that narrows it down a little. What else we got?"

"Martha had some trouble getting through," said Cassandra "It might be because she was in an area where internet reception was patchy."

"Narrows it down," said Flynn "But we've still got a long way to go. It might be better to go there and find out what we're dealing with before we think about continuing."

"Jenny," said Jenkins "You said your father was called the Doctor?"

"That's correct," said Jenny

"I knew I'd heard that name somewhere before," said Jenkins "Hang on."

He walked over, and summoned up a book from the main library. Pulling it out, he opened it up, showing a page with Jenny's father.

"That's him," said Jenny "How is there a book about him? I've been searching the universe for him, and you happen to have a book."

"Perhaps you were looking in the wrong place," said Jenkins, not un-kindly "But, this book also details all companions known of him, and-" he flipped a few pages, to show Martha "It tells us exactly where you need to go."

"Jenkins, set the door," said Flynn, as Jenkins began pulling levers on the table. The globe above them glowed, and the doors to the left they had entered through glowed, too. The Librarians, their Guardian, and the visitor from another world, ran through the doors, into the unknown.
