"Explain it again." I requested. I was laid on the medical chair, Dad next to me with all sorts of monitors running scans.

"Don't you remember?" He asked.

"Sort of," I frowned. "I know why. It's there in my head. I just can't put it into words." He took a deep breath.

"You are a creation of the TARDIS," he began, plonking himself down on the stool next to me. "She can see all of time at once, and she could see it coming. She could see me going to my grave and dying on Trenzalore. So she made me a companion," he smiled. "Someone to save me. Someone to jump into my time stream and keep me alive."

"What about Clara?"

"The TARDIS can see all of time as an overview, I suppose," he sighed. "She doesn't see details until she gets there. She didn't see Clara coming. Much like the rest of us," he fiddled with the stethoscope, untangling the cords. "That's why she didn't like her before. Clara was messing up her plans," he put the ends in his ears. "All she knew was that I was going to die before my time, so she found Messaline. I thought it was a mistake, she got there early and you were created as a result, but apparently not. She orchestrated it so that you were made from me. She didn't want to create someone who could die the next day. That would've been a waste of her energy."

"Is that why I can't die? Why I don't regenerate?" I asked.

"I'll get to that in a second," he replied as he put the stethoscope to my chest. "Your hearts sound normal. That's good. How did you get from Messaline to Earth?"

"My pod," I answered. "When I was flying away from Messaline, I saw…"

"Saw what?"

"The TARDIS," I swallowed. "It felt like she was towing me."

"She was making sure we found each other," Dad said delicately. "After I left you there."

"And that's why Vastra's letter dropped into my room," I wondered. "But when we were above Trenzalore, she wouldn't take us down there. We had to turn off the anti-gravs."

"I think she's grown to love you," he said. "You're a child of the TARDIS. She wanted me to be saved, but she didn't want you to die." I smiled at the warm vibrations under my fingers.

"I'm a child of the TARDIS?" I repeated. "What does that make me to River?"

"You and River are sort of… sisters."

"That is one screwed up family tree," I chuckled. "And Rose? She had a little bit of TARDIS in her, didn't she?"

"Not Rose as such," he replied. "You're related to the Bad Wolf. But not sisters. More like cousins, I suppose." He turned to one of the screens and examined it.

"So what actually happened on Trenzalore?" I asked. "What's happened to me? I wasn't split into echoes, like Clara."

"Like you said, you're a part of me," he explained, still watching the monitors with Amy's round glasses perched on his nose. "When I went into my own time stream, I wasn't scattered across my life. I was already there. You are a clone of my potential DNA, so you weren't either. But, because of that very slight difference in us, you were split," he turned to me. "Your echoes weren't scattered over history. Yours go back into yourself."

"My regeneration." I said.

"Yes," he nodded. "Whereas my DNA rearranges and creates a new body, your echoes feed back into you each time you die, like they're stored up inside you. You regenerate, but your face doesn't change because you've got lots of Jennys all waiting for their turn."

"Does that mean there's a certain amount, like you have thirteen regenerations?" I asked.

"Possibly," Dad nodded. "But it will be millions. No need to worry just yet." He tapped my hand with a smile, like a kindly old medical doctor would to reassure you. I returned a beam.

"So I'm not technically immortal, then. One day I will die?" He looked at me, his eyes widening sadly as realisation hit him.

"Yes. Yes, I suppose. Why does that make you happy?" He mumbled.

"Well," I shrugged. "I don't want to live forever. I don't want to be alone. I don't want to see all my friends leave," I wrapped my fingers around his palm. "It's good, Dad. I don't have to do those things anymore." He paused, considering my words thoughtfully, before planting a light kiss on my hand.

"Of course," he nodded. "Understandable. Nobody would want that. Unless you're a Dalek, of course," he turned to the monitors. "Ah! Scans are finished." Then, slowly, his happy expression fell.

"What?" I asked immediately. "Dad, what? What's wrong?"

"Nothing," he murmured. "Nothing's wrong."

"Well, what is it, then?" I frowned.

"All that stuff about millions of regenerations? Forget it." He replied, turning back to me with a grin. I sat up as he started bouncing about the room.

"Will you please tell me what's going on?" I shouted over his whoops of joy, chuckling slightly at the sight.

"Oh, Jen!" He cried, pulling me off the medical chair and spinning me round.

"What's happened?" I laughed.

"You!" He exclaimed, kissing my forehead. "You, Jenny Smith, my daughter! My wonderful, brilliant daughter!"

"Explain, Dad!" I ordered.

"You've fulfilled your role," he began. "You've completed your destiny. You've done the job you were born to do!"

"So?"

"So!" He continued, still leaping up and down. "Remember what I said about the TARDIS?"

"She can see all of time, but not details." I nodded.

"Yes!" He laughed. "The TARDIS didn't see me jumping into my own time stream. She never thought you and Clara would survive. Don't you see?"

"See what?" He groaned exaggeratedly.

"You're an anomaly, Jen," he said. "Or rather, you were."

"What are you saying?"

"I'm saying you're not an anomaly anymore," he grinned. "Those echoes aren't inside you."

"So I can die now?" I questioned.

"No," he shook his head. "Think about it." I paused, examining his excited face for a clue.

"Your DNA rearranges during regeneration," I said slowly. "And I don't have echoes of Jenny in me anymore," he nodded eagerly. "I can regenerate?"

"Yes!" He yelled, throwing his arms into the air. "You've got twelve regenerations left. Twelve new faces to use! Twelve new Jennys!" I couldn't help but join in with his beaming expression. "And what's more…" he sat me back down and bent over so we were eye level. "How's your head?"

"It feels… clear, actually," I replied. "Clearer than it's ever been."

"You've got full Time Lord power in that pretty head of yours," he smiled, pointing his index finger right in the middle of my forehead. "You've got all the mental capability that wasn't there before."

"Which means?"

"You're fully Time Lord, Jen!" He cried. "One hundred percent clever Time Lady. With full brain capacity for psychic ability!" He put his fingers either side of my face. "Remember what I said about Time Lords being able to speak to each other through our minds, back on Hedgewick's World?"

"Yes," I nodded. "You said it wasn't needed before."

"Not strictly true," he corrected. "Your mind didn't have the full capabilities to take on another Time Lord's. It's too big, too noisy… But you could hear Jack. His mind is human, much less for you to bring into your head. Easy for you to handle."

"So you're saying we could use our minds to speak to each other?" I confirmed.

"Yes," he nodded, calming down just a little. "It takes practice, but we can work on it," he lifted me into a hug. "You are going to be spectacular, Jen. Just spectacular."

-~oOo~-

During the following few weeks, we spent a lot of time huddled in the TARDIS library. Both of us wanted to build up and establish my psychic ability as a Time Lady; me because once I found out about the possibility I became very impatient, and Dad because he had been missing that connection with another Gallifreyan for hundreds of years. Not that he said that, of course. I heard it in his mind.

Those hours had been put to good use. Dad said that my mind had progressed faster than he had imagined and I was close to full control. It also came in very handy, we found, when faced with another alien trying to destroy the world; that Abzorbaloff got quite confused…

Once we'd both become slightly mad from all that time in our heads, we decided that it was a good idea to see how Clara was doing, so made our way to the Maitland's house. As we expected, she was in a little bit of a state, but not because of what had happened on Trenzalore.

"Going somewhere?" I asked lightly as we walked into her attic room. Dozens of cardboard boxes were stacked on top of one another, each open with odd bits and bobs spilling out. The bed was stripped down to the frame and a mattress. A large suitcase was laid on its back next to the wardrobe, clothes stretching between the two like they were desperately clinging to the hangers. Clara herself appeared just as flustered as her nearly empty room.

"I don't know!" She wailed, thumping down on to the sheet-less mattress and throwing her hands over her eyes.

"You must be, otherwise you wouldn't be packing," Dad replied without missing a beat, tossing a Rubiks cube between his hands that he'd pulled from a box. "Unless you're unpacking, in which case you haven't got very far."

"No," she groaned, letting herself fall back on to the bed heavily. "I am going."

"And that's a problem because…?" I frowned.

"Because," she huffed, slapping her palms on to her lap. "I don't have anywhere to go."

"Well, that's a lie." I replied.

"You always have somewhere to go." Dad continued, plonking himself down next to her.

"Where?" She grunted.

"The TARDIS, where else?" I grinned, hopping to her other side.

"I mean on Earth." She sighed loudly.

"Clara Oswald, there is nothing wrong with living in a bigger on the inside blue box." Dad cried.

"But I need somewhere to live on Earth," she argued, sitting up again. "I can't go whizzing about space all the time. And I can't go back to my Dad's, that's not happening. I don't even have a job!"

"If you don't have anywhere to live, then why are you moving out?" I asked.

"Mr Maitland found a permanent nanny," Clara began. "Like he said he would. But I haven't found anywhere to go! What am I going to do?" I patted her back lightly as she leaned forwards with her head in her hands.

"I know of somewhere." I smiled.

-~oOo~-

I opened the door slowly, ignoring the cold wind that was biting at my skin. The block itself was quiet and if we didn't know any better, deserted. Only the flinching curtains as we passed living room windows alerted us to the neighbours' presence.

I wasn't there, of course, when it happened. But I was prepared to put money on the fact that everything inside the flat was exactly as it was before, just with a thin layer of dust atop each shelf and coating every photo frame. The hallway was dark when we entered, despite it being midday, as if their departure had damaged the heart of the flat. Hopefully a new tenant would change that.

"Here we go." I muttered, flicking the nearest light switch and illuminating the hall in a yellow glow. I led us into the living room, where the cushions were strewn haphazardly over the sofa and a couple on the floor, as if they'd been sat there a few moments before.

"Are you sure this is empty?" Clara frowned uncertainly.

"Positive," I replied, quickly picking up the cushions and tossing them on to the sofa, trying to ignore the guilt gnawing at me. "This is the living room, obviously. And the kitchen's just through there." I pointed at the opposite wall, where the serving hatch was missing its doors. Clara flicked a couple more switches as she made her way across the room, casting a light over the photos adorning the shelves.

"I'm sorry," I said silently, watching Dad lean against the door frame forlornly out of the corner of my eye. He remained quiet. "Are you OK?"

"I'm always OK." He replied almost immediately. I didn't believe him. I could feel his pain, and he knew that.

"Looks good," Clara smiled as she returned from the kitchen. "Not sure I can afford it, though. Not without a job."

"Not a problem," I beamed. "Bought, signed and paid for. It's all yours, Oswald."

"What do you mean?" She frowned, switching her stare between Dad and me.

"This place," Dad replied, putting on a cheerful tone. "It's yours. If you want it."

"You mean, you've already bought it?" She said, astonished.

"Yep," I nodded. "Ready to move in whenever. No rent to pay, no mortgage, no bills, we've taken care of that, too."

"You're not serious?" She exclaimed.

"For once we really are." I grinned, and in a second, Clara had launched herself at the pair of us.

"I cannot thank you enough," she laughed as we all hugged. "But why?"

"Well, you deserve it." I replied.

"You saved us, Clara Oswald." Dad added. And with that, we turned to go back to the TARDIS, but not before I picked up a smeary, dusty photo of them both in happier times.

-~oOo~-

"Who were they?" Clara asked in a murmur, cross-legged opposite me on my bed with a steaming mug of tea by her lips.

"Don't you remember?" I asked, placing the photo frame delicately on my bedside table.

"I recognise her face," she frowned, sipping her tea thoughtfully. "But nothing more than that." I sighed.

"Rose Tyler," I began. "She lived in that flat on the Powell Estate with her mum, Jackie. Her dad died when she was a baby. That's Mickey," I explained, pointing to a photo of him and Martha on my wall. "He was Rose's boyfriend," I smiled. "Well, until Dad showed up."

"The Doctor? Really?" Clara snorted.

"He wasn't as… clumsy in those days," I chuckled. "Anyway, Rose met Dad and became his companion. Just like you did. Apart from, he didn't meet different versions of her beforehand. So they travelled, did this and that, defeated the Daleks, saved the Earth, you know the way it goes," my face fell. "Then there was a battle. Do you remember back in 2007, those Cybermen everywhere? The ghosts?" Clara nodded. "Well, in order to save the planet, that time Dad had to make a sacrifice. He and Rose had to be separated. And they were… Dad stayed here, and Rose and her mum and Mickey were left trapped in a parallel world with no way of coming back. The walls closed," I paused. "But they're fine. Jackie has a parallel version of her husband, Mickey's married with a baby, and Rose… well. Let's just say she found her Doctor again." Clara took a gulp of tea.

"Blimey. Is the end that dramatic for all of us?" I stared at my wall of photos.

"Yeah." I frowned. She turned to face the photos with me, sliding off the bed to take a closer look.

"What happened to them?" She whispered.

"Rose is living with a human version of the Doctor on a parallel Earth," I started. "Martha's family were enslaved and tortured. Donna lost her entire memory of ever travelling in the TARDIS. Charlie was pulled into the Time War and died on Gallifrey. River was stolen as a baby, made into a psychopath to kill Dad, then died to save him. Amy and Rory are trapped back in time. And Jack… Jack is immortal. He's had to watch so many of his friends die, and it won't ever stop." There was an eerie silence as my voice echoed into the TARDIS walls.

"Better make the most of it then." Clara said quietly, before turning to me with a smile.

-~oOo~-

We may have already gotten Clara the flat and paid for her bills for the next five years, but I wasn't done yet. Clara had a natural ability, and I didn't want that to go to waste. So I put in a favour with a dear old friend.

Ian Chesterton was governor of Coal Hill School, and a rather excellent one at that. When I asked him if he would do something for Dad and me, he didn't even hesitate to say yes. He didn't even need to see the reference that Dad had meticulously written out. Ian agreed immediately.

Miss Oswald was hired to teach English at Coal Hill, a job perfectly suited to her incredible ways with children. We slipped the acceptance letter through her new flat letterbox and left her to settle in to her new life as a teacher.

We dropped in a few times to see how she was getting on (the first time we both got a slap because apparently 'we shouldn't have done that'), but it wasn't until we called her back to the TARDIS one day that things really began to change.

The day things changed for all of us.

The day of the Doctor.

LunaRoseDiCaprio: The beginning of this felt like that chapter in Harry Potter and the Half Blood Prince where it's literally just Dumbledore explaining the plot of the whole series ;)

I'm really sorry if this felt a little rushed... it's because it was. Two assignments due in one week with a six week placement teaching in school coming up the week after is really, really quite tricky to balance. I tried my best :)

Next up, as you can probably guess… it's the big one. On the 9th November, I will be uploading for you a Jenny version of the pure brilliance that is 'The Day of the Doctor', part one… I hope you won't hate me…

I won't be doing the sneak peeks for reviewers this week as I don't want to spoil anything for you :)
