It had been a while since the Doctor and I had last been on Earth. It was nice to come back every now and then and feel a bit of… normality. Although, you can't get much normality when you're with the Doctor, whether you were on Earth or not. But it was still nice. While it still wasn't what I've got used to calling my Earth, it was all the same apart from the obvious. It just gave me a sense of feeling at home again.

The two of us walked through a busy London street, dodging the many people that were out in the morning rush hour as they hurriedly made their way to their jobs that were awaiting them. We stopped as we came to a building that had a rather large plaque with the word 'Adipose Industries' written on it. The two of us looked at each other, giving a small a nod as we both made our way closer to the building.

This whole situation had occurred during one of the many phone calls that I had with Owen, an effort to try and entertain him during the long nights he had to spend alone in his flat. Adipose Industries was a company that sold weight loss pills. Owen's mother had been on them apparently, and she'd lost a drastic amount on them in just a few weeks and both of us had come onto a quick agreement that nothing that was human would be able to do that. Not in this day and age anyway. So, instead of the whole Torchwood team making a long journey out to London, I made the suggestion that me and the Doctor would check it out. We needed something really exciting after all, it had been a few days since we'd had to run for our lives, and as mad as it sounds, I was missing it.

So here we were, going undercover as a pair of Health and Safety inspectors. I'd smartened myself up a bit for the job, wearing a black blazer along with a white top and a pair of black jeans. However, the shoes never changed and I wore my white converse. The Doctor just was wearing his brown suit this time, trench coat and white converse included.

We neared the back of the building, stopping at a fire exit. The Doctor pulled out his sonic screwdriver as I went on look out, checking to see no one was watching as he broke into the door. The exit lit up with a large spark and a loud crack as the Doctor finally got us inside and the two of us slipped through into a long abandoned corridor.

We walked through the rather long corridor as we tried to find our way around the place. The Doctor reached into his pockets as he searched around for his physic paper and turned his head to look at me. "Nina Dobrev, yeah?" I nodded. Ever since I went undercover at the pharm I had grown to like the name Nina Dobrev as my undercover name. The Doctor nodded as well and he pulled the physic paper out as a security guard came walking our way. "John Smith and Nina Dobrev, Health and Safety." He said, flashing the physic paper. The security guard simply nodded as we continued walking.

From there we found our way to a lecture hall where we had heard a presentation was going on, thankfully not bumping into anyone else on the way there. However, just as a small precaution we decided to sneak into the projector room. I stood over on the left side of the projector, peering through the small window into the lecture hall. The Doctor stood behind me, his brainy specs on as he done the same and rested his arms lazily on my shoulders.

Finally, after a couple of dozen people filed into the room and took their seats, a woman stepped onto the platform. I could tell instantly from the way she dressed and the intimidating look she had about her that she was in charge of this whole outfit. She wore a long, black pencil skirt with a matching black suit jacket accompanied by a pair of black heels. Her silky light blonde hair was tied up into a neat, tight bun. A pair of thick, black, square glasses were placed on top of her icy blue eyes. The only colour to her outfit was her bright red lipstick and red polish on her nails which had been manicured perfectly.

"Adipose Industries, the 21st century way to lose weight." She began. "No exercise, no diet, no pain, just lifelong freedom from fat, the holy grail of the modern age. And here it is." She lifted up a small red and white pill in her hands, holding it between her thumb and one of her fingers. "You just take one capsule, one capsule, once a day for three weeks. And the fat, as they say…"

"The fat just walks away." A computerized voice finished off for her as the words appeared on the screen behind her.

"Excuse me, Miss Foster, if I could?" A dark skinned woman in a white striped shirt and brown jacket cut in. "I'm Penny Carter, science correspondent for The Observer. There are a thousand diet pills on the market, a thousand conmen stealing people's money. How do we know the fat isn't going straight into your back account?"

I couldn't help but nod in agreement. Even though I knew this one seemed to work, I knew for fact there were so many false diet plan schemes out there on the market. "Point." I mumbled, listening intently to Miss Fosters reply.

"Oh, Penny." She said in a mockingly sweet voice. "If cynicism burnt off calories, we'd all be thin as rakes." She gave off a smile that seemed alien to her face, trying to be funny, but her voice just made it sound strict and mocking. "But if you want the science, I can oblige." She took her glasses off smugly as the presentation began.

"Adipose Industries." The computerized voice spoke again as a diagram of a human body along with other chemicals appeared onto the screen. "The Adipose capsule is composed of a synthesised, mobilising lipase, bound to a large protein molecule. The mobilising lipase breaks up the triglycerides stored in the adipose cells, which then enter…"

I caught sight of a man entering the room in the corner of my eye, immediately noticing the two of us. I nudged the Doctor lightly, drawing his attention away from the presentation and nodded towards the man. "Health and Safety." The Doctor said, using the default without seeing the flaw as he held up the psychic paper and turned his attention back to the presentation.

The man frowned, his head snapping to look at me for some sort of explanation for why Health and Safety inspectors would even be here. My mind quickly searched for something to say that he would probably buy. "Film Department." I blurted out. However, the man seemed to take it and nodded, turning his attention back to his job.

The presentation ended and Miss Foster reappeared back on the platform. "100 percent legal, 100 percent effective."

"But, can I just ask." Penny Carter piped up again, clearly not done. "How many people have taken the pills to date?"

"We've already got one million customers in the Greater London area alone," Miss Foster answered placing her glasses back on. She was clearly starting to sound annoyed by Penny's questions, but was doing a pretty good job of hiding it. "But from next week, we start rolling out nationwide. The future starts here. And Britain will be thin."

XOXO

The two of us walked into the call centre of Adipose Industries. Many phones were going off with various employees answering the calls, using the same introduction of "Good Morning, I represent Adipose Industries."

We quickly slipped into one of the cubicles, each of us pulling a seat with us as we took a seat next to a nice looking woman who was currently on the phone to a customer. "We deliver within three working days…"

"John Smith and Nina Dobrev." The Doctor whispered, holding out the psychic paper to her. "Health and Safety. Don't mind us."

The woman turned around as she continued talking to the customer on the line, although her attention was obviously all focused on the Doctor who seemed completely oblivious towards it. "The box comes with 21 days' worth of pills, a full information pack and our special gift, and Adipose Industries pendent." Curiously the Doctor picked the said pendent up out of its box and stared at it closely, fiddling around with it. "It's made of 18 carat gold and it's yours for free. No, we don't give away pens. Sorry. No, I can't make an exception. No."

"We're going to need to keep this for testing." I said to the woman as she ended the phone call with her client, pointing to the pendent which the Doctor finally stopped staring at and turned his attention back to the two of us. "And we'll need a list of your clients."

"Yeah." The Doctor agreed. "Could you print it off?"

"Of course. Just give me a second." The woman replied, turning to her computer as she brought the list of information up onto the screen.

"And that's the printer there right?" I asked her, popping my head up and nodding in the direction of where I had spotted a printer earlier on.

The woman looked over in the direction I had gestured in and nodded. "By the plant, yeah."

"Fabulous."

"Has it got paper?" The Doctor asked, popping his head up to look over at the printer as well.

"Yeah, Jimbo keeps it stocked." She answered.

"Excuse me everyone if I could have your attention." Someone called, and I recognised the cold, strict voice to be Miss Foster. Both me and the Doctor popped our heads up slightly over the cubicle to look at her as all the employees stood up. As she began talking, she turned her head around in our direction and we quickly shot down behind the cubicle and out of sight. "On average, you're each selling 40 Adipose packs per day. That's not enough. I want 100 sales per person per day. And if not, you'll be replaced. 'Cause if anyone's good at trimming the fat, it's me. Now, back to it."

Miss Foster walked off, with two security guards in tow. The Doctor and I both turned to look at each other shuddering slightly at the woman's harsh cold words. "Anyway, if you could print that off, thanks." The Doctor said, getting back to the point. Neither of us really wanted to stay here much longer, risking exposure. Especially with that woman in charge of the whole business. The woman nodded, pressing the print button. "Thanks, then." The Doctor said happily as we both stood up to leave, but the woman pulled him back down in his seat again and handed him a piece of paper and I smirked, leaning against the cubicle. "Oh. What's that?"

"My telephone number." She said simply with a flirtatious look in her eyes.

"What for?" The Doctor asked, still not quiet getting it, still oblivious.

"Health and Safety." She answered, looking at him suggestively. "You be Health. I'll be Safety."

It was then that the Doctor finally got it, and I had to bit my lip to stop the giggle that was threatening to escape my lips. "Oh, ah… but that contravenes, um, paragraph five, subsection C. Sorry." He placed the paper with her phone number back down on the table as he grabbed my hand pulling me away towards the printer without another word.

It was then that I began to giggle, causing the Doctor to shoot me a glare. "Sorry." I looked at him with an innocent smile. "But it's too funny. That was a classic. And you really had no clue." We stopped at the printer and I looked down to see that it was completely empty. I frowned. "Where's the printing?"

The Doctor frowned, looking around to see if it had been put anywhere else. I looked to see if it generally did have paper, which it did while the Doctor looked around the photocopier to see if it was there but all to no result. "Better go back to her then." I said, nodding towards the cubicle we'd previously been in with a smirk.

The Doctor groaned running a hand through his hair as he made his way over, leaning against the outside of the cubicle. I followed doing the same. The Doctor chuckled as the woman turned and smirked at him as I done the same. "Hi. Us again."

XOXO

The Doctor walked up to the door of one Mr Rodger Davey with me walking closely behind him. He was the client that's house that was situated the closest to the TARDIS, and since we were both feeling incredibly lazy, we choe him. As we both reached the door the Doctor knocked on it and we waited patiently as Rodger opened the door. I frowned momentarily; the man didn't look like he needed to lose any weight at all. But I soon brushed it off as the Doctor spoke.

"Mr Rodger Davey, I'm calling on behalf of Adipose Industries." He said and flashed up the psychic paper.

"We just need to ask you a few questions." I added, flashing him a small smile. "Mind if we come in?"

The man looked between the two of us and nodded, smiling as he ushered both of us into the house and into the living room. Rodger went and sat in his chair, while I went and sat to the left of the room on his sofa, the Doctor's trench coat placed next to me. The Doctor however just paced up and down the living room.

"Anyway, I'm Nina Dobrev and this is John Smith." I said as I gestured up to the pacing Time Lord. "Tell me, how long have you been using the Adipose pills?"

"I've been on the pills two weeks now. I've lost 14 kilos." Rodger answered, sounding rather proud of himself.

"That's the same amount every day?" The Doctor asked him, turning around to look at him for one short moment before he began pacing again.

"One kilo exactly." Rodger confirmed. "You wake up, and it's disappeared overnight. Well, technically speaking, it's gone by ten past one in the morning."

Both mine and the Doctor's heads turned around to look at the man, surprised by his accuracy. "What makes you say that?" The Doctor asked.

"That's when I get woken up." Rodger explained and shrugged. "Might as well weigh myself at the same time." The two of us shared a look before we continued listening to him. "It is driving me mad. Ten minutes past one, every night, bang on the dot, without fail, the burglar alarm goes off."

The Doctor and I frowned. "Can you show us?" The Doctor asked, becoming increasingly suspicious.

Rodger merely shrugged as he stood up from his chair and led us back outside the front door again. The three of us stood outside his house, looking up at the burglar alarm installed just outside the house. "I've had experts in, I've had it replaced, I've even phoned Watchdog. But no, ten past one in the morning, off it goes."

"But with no Burglars?" I asked, turning to him with a frown.

"Nothing. I've given up looking."

"Tell me, Rodger, have you got a cat flap?" The Doctor suddenly asked. I turned to him with a frown before my face turned into one of realization. That was a brilliant idea.

"Uh, yeah I do actually." Rodger replied. He pointed down to the small cat flap at the bottom of the front door. The Doctor and Rodger both went inside kneeling down so and peered through it while I knelt down on the outside so that I would be able to have a look at it as well. The Doctor had his sonic screwdriver out, holding the cat flap open so he could inspect it. "It was here when I bought the house. I've never bothered with it really. I'm not a cat person."

"No we've met cat people." The Doctor said sort of distantly as he nodded over to me. "You're nothing like them." I grinned, remembering Thomas Brannigan from the New New York motorway. He was right. Definitely nothing like them, looks and personality wise.

"Is that what it is, though, cats getting inside the house?" Rodger asked. My eyes moved down to the floor as I sighed. It certainly wasn't going to be that simple.

"Well, the thing about cat flaps is they don't just let things in, they let things out as well." The Doctor commented, continuing to eye the cat flap.

"Like what?" Rodger asked.

My eyes widened slightly as I remembered something from back at the Adipose building earlier in the day. "'The fat just walks away'" I quoted, mumbling slightly before looking to the Doctor. "They can't mean that literally, can they?"

The Doctor was quiet a moment before he shrugged. "Who knows, maybe. Now, come on you." He dropped the cat flap and I saw him jump onto his feet on the other side of the door followed shortly by Rodger. The door then opened not too long after at the Doctor stepped outside as he pulled his trench coat on. "Well, thanks for your help." He said happily.

"Tell you what," I piped in, my eyes moving over to Rodger. "Maybe you could lay off the pills for a week or so." I said, concerned for him. He didn't exactly need them anyway, and I didn't want him to be at risk. There was a sudden beeping coming from the Doctor's pocket and my head shot up to him. "Have we got one?"

The Doctor said nothing as he pulled out a device he had made only the other day, which was flashing red, confirming my earlier question. "Ooh, gotta go! Sorry!" The Doctor shouted over to Rodger as he grabbed hold of my hand and we ran down the street in the direction the device was indicating to.

The device led us blocks and blocks away. We had run for about two blocks when the Doctor stopped suddenly, almost ripping my arm off in the process. I retracted my arm suddenly as I turned to look at him. The bleeping coming from the device which was fading. He banged his hand on it, blowing on it a couple of times and the device began to work again. He grabbed hold of my hand once more as we bolted down the street again, only for him to stop suddenly again after a couple more streets. I slapped him on the arm but he just ignored my shaking the device as it dinged and he took off again.

We ran into the street, stopping as we tried to make sense of where the device was indicating. I suddenly felt someone grab hold of me by the waist and almost screamed, until I realized it was the Doctor. He pulled me back onto the path just as a black van came speeding past us, beeping at us. I was about to stick my fingers up at the driver when the device suddenly beeped and I looked down confused. Quickly realizing the signal was coming from the van itself, we chased after it, taking a short cut as it turned a corner. However, it wasn't long until the van went out of range and we lost the signal. We both came to a halt, looking down at the device in disappointment.

"Damn it." I cursed as I tried to regain my breath.

The two of us sighed and we slowly made our way back to our home, the TARDIS.

Little did we know that just down the other street, standing there was Donna Noble.

XOXO

I sighed, bending down onto my knees as my eyes scanned the fridges contents, trying to find something that I wanted to eat. After a few minutes I made my decision and grabbed a handful of jubbly ice lollies and a bottle on banana milkshake and went on my way back to the console room where the Doctor was currently examining the Adipose Industries pendant we had collected earlier today.

"Ooh fascinating." I heard the Doctor talking as I got closer to the console room. "Seems to be a bio-flip digital stich specifically designed for…" He stopped mid-sentence as he probably finally realized I wasn't in the room. It was then I heard him call out for me in a whiny tone. "Kat."

I rolled my eyes, quickening my pace as I finally reached the console room. "Mhm." I mumbled as I sucked on one of the ice lollies.

The Doctor turned around to look at me slightly surprised. "Where did you go?"

I rolled my eyes again. Obviously he hadn't been listening to me while he had been working. I swear that he just carries on talking while I'm away. Just a minute ago had been proof of that. "I told you, I needed to the loo."

The Doctor raised an eyebrow, obviously not being able to recall me saying that. "When did you say that?"

"About five minutes ago. I was hungry so I went and got food as well. Here, catch." I threw one of the ice pops at him, which he caught easily and began to open it.

"I didn't hear you say you were going." He mumbled, sucking on the ice lolly as continued to look at the pendent.

"Of course you didn't. You never listen when you're caught up in these things." I said, moving over to join him at the console. "Anyway, what did you find exactly?"

"Oh, right, yeah." The Doctor moved me around so I was standing in front of the capsule and placed a magnifying glass over the top of it as I looked down. After a few seconds I looked up at him confused, and he went on a little scientific rant.

I shook my head. "Make it into a one liner so I can at least try to understand?"

The Doctor sighed. "Basically, one touch and the pendent bio-tunes itself to its owner." He stated simply.

I nodded slowly. Although, I still didn't quite understand it completely. "So, we're going back, right?"

"Oh yes." The Doctor nodded. He finished off his ice pop and quickly rushed around the console, sending us into flight. He danced around it, flicking various buttons and leavers on his way around. He grabbed a metal hammer, banging it on the column. I winced. It didn't sound very nice. But I never brought it up. After pressing a few more buttons, we landed and slowly made our way back to the fire exit.

The routine went the same as it had done just twenty four hours ago. I kept a look out while the Doctor soniced the door open, causing it to crackle loudly and send sparks everywhere and then we crept inside. We walked along the corridors quietly, before we came across what looked like a cupboard. The Doctor took one long down either end of the corridor before he opened it, grabbing me by the hand as he pulled me inside, locking the door behind us. I sighed, leaning against one of the walls, as the Doctor done the same thing.

"Now all we have to do is wait." I mumbled quietly, staring blankly into the air.

"Yep." The Doctor shrugged. "Can't be that hard, can it?"

"Nope."

XOXO

I couldn't have been anymore wrong. Waiting was torture. I could barely even sit still through a 3 hour long film, so sitting here; waiting for a full day was hell. The Doctor had done a scan to search for any alien tech in the cupboard just out of plain boredom. But surprisingly there was. He had tried to hack into it, but it happened to be triple deadlocked, which was surprising as well. There had been things deadlocked and double deadlocked. But triple was new. A good thing was we had official proof now that Adipose Industries was indeed alien. We just needed to wait for night to come so we could truly investigate.

We'd tried to do a lot of things to entertain ourselves during the extremely long time we had to wait. We had a go at rock paper scissors, which came up to a draw when we got bored. We tried thumb wars, staring competitions. We even played mercy, but that didn't last long. It turned out I had an infinitive amount of pressure points. As did the Doctor. It ended up with the Doctor in the end just fiddling around with the settings on his sonic screwdriver. I on the other hand, tugged at my hair, re-laced my shoes and then began tapping out tunes on my knee again.

Finally, after nine hours and twenty minutes of waiting, the employees left their work and were heading back home. The Doctor jumped up, helping me up as well and he soniced the door open again and we stepped back into the long corridor. We were quiet as we walked around, Miss Foster was in the building somewhere and we didn't want to catch her attention just yet.

We decided to make our way outside and up to the roof. A building like Adipose Industries would probably have all sorts of intruder alarms after work time, and we didn't want to be setting any of them off. The Doctor bounded up a window cleaners cradle nearby and outstretched his arms to help me get inside.

"Ha, no." I said shaking my head vigorously. "Not happening."

"Kat." He whined. "Please get in."

"No." I said simply. "This building's like 20 stories up. And those things wobble. I don't like heights. It was bad enough on the Titanic, and climbing up the empire state building after you and—"

"Yeah, yeah, I get it. You hate heights." The Doctor cut me off. "But this is the only way we can find out what they're doing."

"Well, how about you go down and find out what they're doing and report back to me later."

"Oh for God sake." The Doctor mumbled. He clambered out of the cradle and I frowned slightly. He walked up to me and the next minute I knew he was picking me up and throwing me over his shoulder, carrying me towards the cradle.

"Doctor! Stop it! Put me down!" I hissed at him, not wanting to speak too loudly in fear someone might hear us. He finally complied as he stepped into the cradle placing me down in it as well. Before I had a chance to clamber out, he pressed a button and the cradle began to descend down the building. "I hate you." I glared at him, not even daring to look down. The Doctor said nothing, pressing a button pulling the cradle to a halt as we reached what looked like Miss Foster's office. Our thoughts were confirmed when the door opened and Miss Foster walked through, two security with her as they dragged the science correspondent from the other day Penny into the room. Both the Doctor and I ducked down so that we were unseen and the Doctor pulled out his stethoscope placing it on the wall so that we could hear.

"You can't tie me up." Penny exclaimed. I rolled my eyes slightly. Well, clearly they can seeming as they're doing it right now. "What sort of country do you think this is?"

"Oh, it's a beautifully fat country." Miss Foster replied. "And believe me; I've travelled a long way to find obesity on this scale."

"So come on then, Miss Foster. Those pills, what are they?" Penny asked.

"Well, you might as well have a scoop, since you'll never see it printed." The Doctor placed the stethoscope cautiously up onto the window so we could hear better. "This is the spark of life."

"And what's that supposed to mean?" Penny asked, clearly getting annoyed. Although, she had pretty much every right to be. She was tied up in a room with a scary mad woman after all.

"Officially the capsule attracts all the fat cells and flushes them away." Miss Foster explained. "Well, it certainly attracts them, that part's true. But it binds the fat together and galvanises it to form a body." My eyebrows shot up at that, and I turned to give the Doctor a look.

"What do you mean a body?" Penny asked, clearly confused.

"I am surprised you never asked about my name. I chose it well." A fake name. So she is an alien. I thought. A part of me had been thinking that maybe she was just a human working under alien commands. "Foster. As in 'foster mother'. And these…" There was a sound of a drawer opening before Miss Foster finally spoke up again. "Are my children."

The Doctor and I looked at each other before nodding and the two of us slowly rose up to risk a look through the window. My eye brows shot up as soon as I did so. Placed onto the table was a small blob of white fat, a small, cute little grin plastered on its face. I had to try my best not to allow a 'aw' to escape from my lips. The little thing was so cute. Certainly not what I had expected.

"Are you kidding me?" Penny stammered, rather alarmed as she stared at the little blob on the table. "What the hell is that?"

"Adipose." Miss Foster answered, walking round her desk and standing in front of penny. "It's called an adipose, made out of living fat. Stripped from ordinary human people…"

Something in the corner of my eye suddenly grabbed my attention. I stopped listening to the conversation between Miss Foster and Penny as my eyes flittered over. My mouth dropped open instantly as I saw the fiery redhead spying though the office door. The fiery redhead in question was Donna Noble. I had stop myself from letting out a little squeal as my eyes moved back to the Doctor, whose attention was still focused on the other two. I nudged him arm and he turned to look at me, pointing over in the direction of Donna, the Doctor's eyes moved to look at her, just as Donna's eyes moved to meet us. A gleeful look on her face as she caught sight of him. The Doctor was stunned, having to do a double take to see if it was really her.

"Donna?" The Doctor mouthed to her through the window.

"Doctor!" Donna mouthed back, extremely excited. This was the start of a silent conversation between the two of them, and my eyes flittered between on the two of them. Trying to keep myself from jumping down in excitement. I loved Donna in the Christmas special. And now here she was! It was brilliant.

"But… what? Wha… what?" He responded, completely and utterly confused.

"Oh. My. God." Donna mouthed. A grin was still plastered on her face as she stared at the confused Time Lord.

"But… how?"

"It's me!" Donna pointed to herself. Yes, it's you. Donna Noble. Oh, my God. I thought to myself, resisting the urge to jump up and down in excitement.

"Yes, I can see that." The Doctor mouthed and mimed in response.

"Oh, this is brilliant!" Donna stuck her thumbs up, ecstatic. Yes, Donna, it really is! It was then I realized how much she actually looked like Catherine Tate, and the urge to jump up and down became even stronger. But then again, the Doctor does look like David Tennant. My eyes moved back over to him and my eyes widened, like I was only just realizing how much he truly looked like him. I squeal suddenly escaped from my lips and the Doctor's head snapped to look at me.

"Oh, no. You're fangirling now? Really?" I just stared at him grinning and he rolled his eyes, his attention moving back to Donna as he allowed me to continue to fangirl to my heart's content. "What the hell are you doing there?" He mouthed to her and pointed a finger at her.

"I was looking for you!" Came Donna's reply.

The Doctor pointed at himself questioningly. "What for?"

"I came here, trouble, read about it, on the internet." Donna mouthed and mimed her explanation. "I thought trouble = you! And this place is weird! Pills! So I hid. Back there. Crept along. Heard this lot. Looked. You! 'Cause they…" Donna stuck a thumb in Miss Foster and Penny's direction, stopping suddenly. Both mine and the Doctor's eyes moved and froze, seeing that Miss Foster had stopped her conversation with Penny and was now watching the three of us.

"Are we interrupting you?" She asked us, looking between us.

Our eyes moved back over to Donna as hers moved back over to us. "Run!" The two of us mouthed at the same time and with that Donna dashed away from the door and out of sight.

"Get her!" Miss Foster commanded her two guards. Trying to buy Donna some more time the Doctor grabbed his sonic, locking the door shut. "And them." She added. The Doctor turned the sonic screwdriver up to the cradle and we were zoomed up to the top of the roof again, with me holding onto the Doctor all the way.

The Doctor scrambled out of the cradle and dragged me out along with him and we both ran towards the doors leading to the stairwell. We ran down them as fast as we could. Half way down one of the few stairs we had run down we bumped into Donna who immediately pulled the Doctor into a tight hug which he returned.

"Oh my God!" She exclaimed, pulling out of the hug to look at him. "I don't believe it! You've even got the same suit!" Her eyes suddenly widened, looking at him curiously. "Don't you ever change?"

"He does." I suddenly piped in causing Donna's head to snap around to look at me. "He has one exactly like that one but it's in blue. Started wearing it when he met me. Not too sure why he hadn't worn it before then. Sorry! I'm Nina—" I stopped, shaking my head as I face palmed. "Nope, I'm not. Sorry, I'm Katherine. And can I just say how great it is to actually meet you?"

"Yeah…" The Doctor suddenly piped back in. "Can you both not do this right now?" A loud bang suddenly echoed through the stairwell and both me and the Doctor peered down to see that the guards had made their way out of the office. The Doctor grabbed hold of my hand and with his free hand grabbed hold of Donna's. "Just like old times!" He grinned as the three of us charged back up to the roof.

"'Cause I thought, 'How do you find the Doctor?' And then I just thought, 'Look for trouble and he'll turn up.'" Donna babbled on excitedly as the Doctor made his way back to the cradle and began sonicing with controls, giving me things to hold when I was needed to. "So I looked everywhere. You name it. UFO sightings, crop circles, sea monsters. I looked, I found them all. That song about the bees disappearing, I thought, 'I bet he's connected.' Because the thing is, Doctor, I believe it all now. You opened my eyes to all those amazing things out there, I believe them all. Well, apart from that replica of the Titanic flying over Buckingham Palace on Christmas day. I mean, that's gotta be a hoax!"

"Actually not so much of a hoax." I said, looking up at her with a big grin. "That was us."

"What do you mean the bees are disappearing?" The Doctor asked suddenly as he finished with the controls, jumping into the cradle as he started messing around with that.

"I don't know. That's what it says on the Internet." Donna explained. "On the same site, there was all these conspiracy theories about Adipose Industries, and I thought, 'Let's take a look.'"

"In you get." You called to the two of us, motioning to the cradle.

"What?" I blinked. "No, please. Not again." The Doctor just shot me a look, which I knew instantly meant that if I didn't get into the cradle right now he'd throw me over his shoulder again and carry me in himself. I sighed, making my way into the steps cautiously as the Doctor helped me in.

"You too, Donna." He called out to her.

"What in that thing?" Said in disbelief as she pointed to it.

"Yes, 'in that thing.'"

"But if we go down in that, they'll just call us back up again." Donna argued. She did have a good point. My eyes moved over to the Doctor and raised an eyebrow at him.

"No, no, no, 'cause I locked the controls with a sonic cage." The Doctor explained. "I'm the only one that can control it." With that Donna complied with his orders and climbed up the stairs into the cradle. "Not unless she's got a sonic device of her own, which is very unlikely."

I groaned, holding my head in one hand as I used the other one to whack the Doctor in the arm. I didn't even need to look up at him to know that he was probably pouting, but I did anyway and shot a glare at him. "What have I told you about saying things that are going to jinx us?" The Doctor went to open his mouth again, probably to only to repeat what he had said early to try and defend himself. "Don't you dare say it again."

In the meantime Donna, seeming to trust the Doctor, had climbed into the cradle and was now standing beside us. "It's like I've gone and walked into the domestic zone. Are you two always like this?"

I shrugged, my brows furrowing together in thought for a moment. It was something that was becoming more common, I had to admit that. "Only when he's an idiot." My eyes glanced over to the Doctor to see him staring down at me. "Which is always. So yes, we're always like this."

With that the Doctor set the cradle to descend down the building, making is start with an extra-large jolt as payback for calling him an idiot. I jumped, finding myself suddenly clinging onto him, only for him to smile smugly. As we got further down I began to relax a little and moved away from the Doctor, but still clinging onto the rails. However we were still at a tremendous height and the cradle was going at a ridiculously slow pace.

Suddenly, instead of going down and a controlled, slow pace, the cradle jolted and began to just all down, picking up speed rapidly. I let out a scream as the grip I had on the rails tightened and tried to keep myself standing up. My eyes moved upwards, seeing Miss Foster holding some sort of sonic device in her hand pointed at the controls. I knew it! He's gone and done it again. The Doctor fumbled around in his pocket for his sonic, pointing it up to the controls. The cradle jolted again as it came to a sudden halt and the three of us let out a sigh of relief.

The Doctor jumped up onto his feet, not wanting to even give me a seconds chance to tell him that I told him so. He pointed his sonic at the window. "Hold on! Hold on, we can get in through the window." However, there was a sudden click throughout the whole building as if something was being locked. And the Doctor's sonic wasn't working. "I can't get it open!" He growled in frustration. I sighed, head in my hands once again. Deadlocked. Great.

"Smash it, then!" Donna cried as she picked up a rather large spanner from the tool box and began hammering at the window. The Doctor continued to try with his sonic for short moment until the three of us were all continuously hammering at the window. But the safety glass was far too strong to do any damage.

I heard a crackle and caught sight of a green spark up above. My eyes moved up again to see Miss Foster using her sonic device again, this time pointing it at the cable, which was where the green sparks were coming from as she burnt through it. I gulped, trying to swallow the lump forming in my throat. Shit, shit, shit! "She's cutting the bloody cable!" I cried.

Both the Doctor and Donna only just had enough time to look before for a second before the cable was cut through. It snapped and the cradle swung down onto its side. The Doctor managed to grab hold on the cradle to stop him from falling. However Donna and I weren't as lucky. Donna rolled out first, followed by me. I screamed, grabbing onto the cable around halfway down and clinging onto it for dear life. Donna did the same, but a lot further down than me, only just managing to cling onto a metal piece of the cable right at the bottom.

"Katherine!" The Doctor cried. "Donna!"

"Doctor!" The two of us screeched back.

"Hold on!"

I let out an eye roll, but Donna got to the snarky reply before I did. "I am!"

The Doctor grabbed hold of the cable, trying to pull us both up with it. But the weight of both Donna and me put together was too heavy even for him. He moved away as Miss Foster moved over to the other side, where the second cable that was still intact was. She was going to cut with other one. I only just saw her bring her sonic device up to the cable; ready to cut it and the Doctor raised his screwdriver up as well. It must have caused some shock as Miss Foster suddenly let go of her pen, and it fell down right into the Doctor's hand. The cradle wriggled as he climbed up to the top of the cradle sonicing the windows again.

"I'm gonna fall!" Donna cried form the bottom as she tried to keep her grip on the metal thing.

"Don't say stuff like that!" I shouted down at her as I too tried to keep my grip on the cable. My eyes moved up the Doctor, sending him a glare. "This is your fault you know! Very unlikely she has a sonic device of her own my ass! You jinxed us!"

"Ugh, I should have stayed at home!" I heard Donna complaining from below.

"I won't be a minute!" The Doctor shouted down to the two of us before he crawled through the window he had managed to open now, with the help of Miss Foster sonic device.

The minute he said he'd be felt like an eternity, and I felt my hands start to become sweaty as I continued to try and hold onto the cable. I closed my eyes, praying he'd hurry up at get us soon. My hands became sweatier and a hand slipped off the cable the other one shortly after. Another high-pitched scream came from my mouth, knowing I was going to fall to a certain death when a hand suddenly grabbed hold of my arm. My eyes which had been closed in fear opened to see the Doctor as he pulled me up through the window. I sighed in relief as I got closer to it, scrambling through the small opened and falling to the floor.

"Cut it a bit fine why don't you." I tried to scold him, but couldn't help the laugh that escaped my lips. The Doctor clicked his tongue, helping me up off the floor before darting off to continue his mission and save Donna. I followed him, making our way down to the next floor as we barged through Miss Foster's office. We made our way to the window to open it, as Donna's legs kicked angrily at the air.

"Is anyone going to tell me what's going on?" My eyes moved over, only just noticing that Penny was still there tied up at to the chair like she had been earlier.

"What are you journalist?" The Doctor asked, glancing over at her once before his attention was completely back to Donna as he opened the window.

"Yes!"

"Well then make it up!" The two of us said in unison as I grabbed hold of Donna's legs. The two of us shared and eerie look before I winced in pain as Donna kicked me. "Ow! Donna stop it!"

"Get off!" She shouted down at me.

The Doctor grabbed hold of her as well, trying to stop her kicks. "We've got you! We've got you! Donna, stop kicking!" Despite her protest kicks, we both managed to get her through the window. A lot more graciously that the Doctor had done with me.

Donna let out a sigh, straightening her jacket as she half glared at the Doctor. "I was right. It's always like this with you, isn't it?"

"Oh yes!" The Doctor answered. "And off we go!" The Doctor grabbed hold of my hand again as the three of us darted out the room. There was the sound of Penny protesting and he suddenly stopped halfway down the corridor, turning around as he ran back towards the office, dragging me along with him in the process. He poked his head round the door, flashing his sonic at the ropes she was tied up in. He went to leave again, but poked his head around the door one last time. "Now do yourself a favour. Get out!"

XOXO

We continued to run down the calls, all the way through to the call centre when we skidded to sudden stop, coming face to face with Miss Foster and her two guards. "Well then," Miss Foster remarked, her voice still sounding as patronizing as before. "At last."

"Hello." Donna offered giving a small wave.

"Yeah, hi." I smiled hesitantly as well, waving a little as well.

"Nice to meet you. I'm the Doctor." The Doctor introduced.

"I'm Donna."

"And I'm Katherine."

"Partners in crime." Miss Foster commented with a smile that seemed slightly faked. "And evidently off-worlders, judging by your sonic technology."

"Oh, yes." The Doctor said excitedly as he patted down his pockets. "I've still got your sonic pen." He brought it out and looked down at it. "Nice. I like it. Sleek. It's kind of sleek." He held it out to me and Donna to take a look.

"Oh it's definitely sleek." Donna agreed as she looked down at it.

"Most definitely." I added and flashing a grin up with the Doctor. "I could do with one of those."

The Doctor just rolled his eyes at me, knowing instantly what I was hinting at. His head turned around to Miss Foster as he continued. "And if you were to sign your real name, that would be…?"

"Matron Cofelia of the Five-Straighten Classabindi Nursery Fleet. Intergalactic class." I blinked and shook my head. That name was far long for me to even try and process it in my head.

"A wet nurse." The Doctor muttered. "Using humans are surrogates."

"I've been employed by the Adiposian First Family to foster a new generation after their breeding plant was lost." Miss Foster explained.

"What do you mean lost?" I almost cried. My brows furrowed together and I titled my head to one side. "How can you lose a planet?"

"Oh, the politics are none of my concern." Miss Foster waved us off. "I'm just here to take care of the children on behalf of the parents."

"What, like an outer space super-nanny?" Donna asked. Her face was one of confusion as she tried to keep up with everything.

"Yes, if you like." Miss Foster flashed us another forced smile.

"So…So those little things, they're made out fat, yeah?" Donna asked. "But that woman, Stacey Campbell, there was nothing left of her."

"Oh in a crisis, the adipose can convert bone and hair and internal organs." Miss Foster explained to her. "Makes a little bit sick, poor things."

Both me and Donna scoffed at that. "What about poor Stacey?" Donna asked.

My body seemed to be working faster than my feet and I took a step forwards. However the Doctor grabbed hold of me and pulled me back. His body was tense and I could see the small scowl on his face. "Seeding a level five planet is against galactic law." He said seriously.

"Are you threatening me?" Miss Foster asked her voice completely calm.

"He's trying to help you actually." I sniped. Like he always does. No matter what bad things they do, he always gives you a second chance.

"This is your one chance." The Doctor told her, his serious tone still there. "'Cause if you don't call this off, then I'll have to stop you."

"I hardly think you can stop bullets." Miss Foster said. The two guards cocked their guns and held them up towards us.

The Doctor instantly stood in front of me and Donna. He raise his arms up as he tried to stop them for a moment, "No, hold on, hold on, hold on. One more thing, before… dying. Do you know what happens if you hold to identical sonic devices against each other?" He asked as he pulled out his sonic screwdriver from his jacket pocket.

"No." Miss Foster said and let out an irritated breath.

"Nor me. Let's find out." He held the two blue tips of both sonics against each other. An awful, high pitched noise suddenly resounded through the room. I covered my ears over with my hands as I tried to block the noise out as best as I could, Donna doing the same. Miss Foster and her two guards, also trying to block out the pain seemed more affected however as the three of them hunched over in agony. A glass pane nearby shattered and I rolled my eyes, pushing the Doctor to stop him.

"Come on!"

XOXO

We ran through the building, sprinting around different corners and through different hallways as we tried to keep the guards as far away from our trail as possible. We stopped as we reached the same corridor that we had entered the building in, reaching the cupboard that both me and the Doctor had spent the whole day waiting in. He opened the door to the cupboard and began chucking its contents out and onto the floor.

"Well, that's one solution, hiding in a cupboard." Donna commented, her eyes flickering between the discarded items on the floor and the Doctor. "I like it."

The two of us stepped inside as the Doctor shifted a stone panel over to the side, revealing the alien tech that we had discovered earlier in the day. "Been trying to hack into this thing all day, 'cause the Matron's got a computer core running through the centre of the building. Triple-deadlocked." The Doctor placed his brainy specs on and pulled out Miss Fosters sonic pen from his pocket. "But now I've got this, I can get into it." The Doctor then turned back to the computer, fiddling around with wires. "She's wired the up the whole building. We need a bit of privacy." He grabbed two sparking plugs and pushed them together. I heard a cry of two men not too far down the hall way.

"Doctor!" I hissed, looking down at him wide-eyed. "Did you just zap them?"

"Just enough to stop them." He reassured. His attention moved back to the main problem at hand. "Why has she wired up a tower block? What's it all for?" He grabbed a load of cables, shoving most of them into my arms as he began to work on them, sonicing a few here and there.

"Inducer online." The computer announced.

"You look older." Donna commented quietly.

"Thanks." The Doctor mumbled.

"I can see you're not on your own anymore." She glanced over at me and smiled, almost like she was thankful.

"Oh, yeah proper introduction." The Doctor smiled pointing in between the two of us as he introduced us. Not that Donna Noble really needed any introduction. "Donna Noble, Kat Stewart. Kat Stewart, Donna Noble."

"I hope you're looking after her." She commented, her eyes narrowing slightly.

"She looks after me."

Donna nodded, giving me a knowing look. When she had met the Doctor she had pretty much saved him too, if she hadn't told him to stop he probably would have drowned himself a long with the Racnoss babies. We both had an idea of what it was like, having to look after the Doctor.

"It wasn't just me, anyway." I added, smiling slightly. "We had another friend along for a bit as well.

"Yeah." The Doctor nodded. "Martha she was called. Martha Jones. She was brilliant. And I destroyed half her life." I sighed, elbowing him hard in the side, causing him to jump. "What the hell did I say then?!"

"You said it was your fault." I said calmly. My eyes were serious as I stared up at him. "Don't you ever say that. It wasn't your fault."

The Doctor just smiled at me, pulling me into a quick hug before he returned to his work. "Anyway, she's fine, she's good. She's gone."

"What about Rose?" Donna asked. I felt myself wince slightly. It was still a relatively raw thing for him, even if he didn't want to admit it. It was something he kept buried, as did I with Ryan these days.

"Still lost." The Doctor answered quietly. He looked up at her and raised an eyebrow as he tried to change the subject. "I thought you were going to travel the world?"

"Easier said than done." Donna said. She had noticed the change in topic, I knew that. But like me, she didn't want to push him. "It's like I had that one day with you, and I was going to change. I was going to do so much. Then I woke up the next morning… Same old life. It's like you were never there."

I just nodded my eyes moving down to the floor. That was the truth of it. The Doctor could blunder into your life; change your whole outlook on life with all the wonder of time and space. But then when he leaves, it's like all of that was just a dream, like it never happened. It made me wonder that if I ever got the chance to go back home, if I would take it. Could anyone ever go back to a completely normal life after travelling with the Doctor?

"And I tried… I did try." Donna continued. "I went to Egypt. I was going to go barefoot and everything. And then it's all bus trips and guidebooks and 'Don't drink the water' and then two weeks later you're back home. It's nothing like being with you. I must have been mad turning down that offer."

"What offer?" The Doctor asked. I rolled my eyes. Is he really that stupid? What else is she here for?

"To come with you." Donna reminded him.

"Come with us?" the Doctor asked, seeming a little stunned. I couldn't help but smile. The 'us' thing seemed to be becoming more frequent. It made me feel more welcome, more like I wasn't just someone along for a ride anymore.

"Oh, yes, please!" Donna grinned.

"Right…" The Doctor said. He still seemed a little dazed and uncertain about how we had even got to his point. I however was just as ecstatic as Donna was. Never thought I'd be meeting her, but now she was even probably going be travelling with us! This was brilliant!

"Inducer activated." The computer announced, making the attention of all three of us quickly turn back to it.

"She hasn't has she…?" I asked my eyes moving up to the Doctor.

He just nodded gravely. "She's started the programme."

"Inducer transmitting."

The Doctor quickly bent down, working rapidly at the wires as he tried to stop it while me and Donna couldn't do anything except watch and hope. "So far they're just losing weight. But the Matron's gone up to emergency parthenogenesis." The Doctor quickly explained.

"And that's when they convert…" Donna couldn't even finish her sentence.

"Skeletons, organs, everything." The Doctor finished for her. "A million people are going to die!" He pulled out the golden Adipose pendent from his pocket. He pulled off one end, revealing a chip. "This contains the primary signal. If I can switch it off, the fat goes back to being just fat. He began to hook it up to the computer, but it seemed Miss Foster had other ideas.

"Inducer increasing."

The Doctor's face fell at that and my heart sank. "Bollocks." I muttered. There really wasn't any way out of this now.

"No, no, no! She's doubled it! I need…" He looked around frantically. "I haven't got time. It's too far. I can't override it. They're all going to die!"

"Don't say that, Doctor." I said to him, sternly before my voice softened. "Is there anything we can do?"

"Sorry Kat, but this is way beyond you two. I've got to double the base pulse. I can't…"

"Doctor, tell us, what do you need." Donna pressed.

"I need a second capsule to boost the override, but I've only got the one." The Doctor explained hastily. "I can't save them."

Donna's face suddenly seemed to relax. Her hand reached into her pocket as she casually pulled out a gold chain, and on it was an Adipose pendent. The Doctor's head snapped around and looked at in shock. The three of us grinned bursting into laughter before he snatched the pendent and began wiring it up to the machine. The lights powered down and the small alarm blaring from the computer turned silent.

"Donna Noble you are brilliant!" I grinned at her happily. However the smile dropped from my face just as a loud horn sounded, shaking the entire building.

"What the hell is that?" Donna asked, the three of us looking up to where the sound had come from.

"It's the nursery." The Doctor answered simply.

"When you say 'nursery', you don't meant some crèche just up the road." I said quietly. "You mean…"

"Nursery ship." The Doctor finished my sentence.

"Incoming signal." The computerized voice spoke again and the machine began to light up with its green colour again. A voice message began to sound from the computer. It was spoken in some alien language that I couldn't understand, but by the focused look on the Doctor's face, I could tell he could make sense of it.

"Hadn't we better go and stop them?" Donna asked.

"Hold on, hold on." The Doctor held up a hand to shut her up. "Instructions from the Adiposian First Family." It was silent for a moment as he continued to listen before he began to translate for us. "She's wired up the tower block to convert it into a levitation post…. Ooh." His eyes widened as he pulled back. "We're not the ones in trouble now. She is!" He jumped up, grabbing our hands as we darted off again.

XOXO

We reached the top in a matter of now time. The three of us watched as thousands upon thousands little Adipose babies flew up towards the nursery ship in the blue light of the levitation beam. "What are you going to do, then?" Donna asked. "Blow them up?"

"They're just children. They can't help where they came from." The Doctor defended, looking up as he watched the babies.

"Oh, well, that makes a change from last time." Donna commented. She nudged me lightly and smiled. "Katherine and that Martha must have done you good."

"Yeah, they did. Yeah. Yeah." The Doctor agreed, he looked down at me and smile before looking back to Donna again. "She fancied me. Martha, I mean."

Donna resisted the urge to roll her eyes, but it seemed her mouth moved faster that he brain thought. "Mad Martha, that one. Blind Martha. Charity Martha."

I giggled slightly and shook my head. One of the reasons I loved Donna, she always seemed to make me laugh no matter what. "Leave them alone."

Donna just grinned as we all looked back up. An Adipose baby caught sight of us and waved at us. The three of us waved back. "I'm waving at fat." Donna remarked.

"Actually as a diet plan it sort of works." The Doctor shrugged.

"Create new life and lose weight." I shrugged as well. "Better than any other diet plan out there."

"There she is!" The Doctor suddenly called out, catching sight of Miss Foster as she rose up in the levitation beam. We all rushed over to the sight, as the Doctor called out trying to get her attention. "Matron Cofelia, listen to me!"

"Oh, I don't think so, Doctor. And if I never see you again it'll be too soon." She sneered.

The Doctor just groaned, looking at me annoyed. "Why does no one ever listen?" He then turned back to Matron. "I'm trying to help! Just get across to the roof. Can you shift the levitation beam?"

"What? So you can arrest me?" She snapped.

"Just listen. I saw the Adiposian instructions." The Doctor explained. "They know it's a crime, breeding on Earth, so what's the one thing they want to get rid of? They're accomplice."

"I'm for more than that. I'm Nanny." Matron corrected, raising her hands up to gesture to the babies. "To all these children."

"Yes exactly. You're the nanny." I tried to emphasize the point to her. "Mum and Dad have got their kids now haven't they? So what would they need you for anymore?"

The smile that had been on her face suddenly fell as she realized. But it was too late. The last Adipose baby had reached the ship, and the levitation beam was turned off. Matron instantly plummeted to the floor screaming. The Doctor pulled to him and I buried my face in his chest so I couldn't see, but I still heard the loud thump of her body hitting the pavement.

"Better phone Torchwood." I mumbled as the ship flew away. I pulled away from the Doctor but still refusing to look down. "Don't want people cutting up her body to find she's alien."

XOXO

"Yeah, Owen. I'm fine honest." I said for the second time. I was starting to think that maybe I should have phoned Jack, but I would have probably just got the same with him as well. "I wouldn't be talking to you now if I wasn't okay now, would I?"

"Yeah, yeah. Point taken." He grumbled.

"How's your mum?" I asked concerned. She lived here while he lived in Cardiff. But I'm sure she would have got in contact with him somehow.

Owen just sighed. "She's fine. Shocked. But she'll get over it. Nothing a bottle or two can't fix." He didn't sound phased at all that his mum could have died tonight. But then again, he had already told me before his relationship wasn't the best. She had kicked him out with he was 16, and never really loved him when he was a child. He still tried to make it work, hence how he had found out about the pills in the first place. But something told me it would take a lot more than that.

"That's good." I said, smiling weakly. I caught sight of the Doctor outside the building and walked up to him. "Listen, Miss Fosters body. Could one of you guys pick it up?"

"What for?" He almost whined. Something told me he'd rather not have to do it.

"She's an alien." I said, like it was obvious. "Wouldn't be a good idea if someone found that out now would it?"

"But why do we have to." His voice was still whiny. "Can't you—"

"Oh just do it will you!" I snapped. The Doctor's eyebrows shot up and I winced slightly as a couple members of the public shot around to stare at me. "Please?" I asked my tone a lot softer than before.

"Fine." Owen sighed. "Will I see you there?"

"Probably not. Sorry, we sort of have a companion situation." I explained as I saw Donna walking up to us.

"What?"

"Oh, ask Jack. He'll get it. Anyway, really got to go. See you around?"

"Yeah. Bye, sweetheart."

I hung up placing my phone back in my pocket as the Doctor held out Marton's sonic pen to me. "Sorry. But why are you holding that out to me?"

"You don't want it?" The Doctor raised his eyebrows. I instantly shook my head, taking it out of his hand. "I was going to throw it in the bin but…. Well, you said you would like one earlier back in there. And it's better that just leaving it in there and risking it getting into the wrong hands. So have it. It's yours."

I looked at him, slightly shocked. I grinned like a manic, pulling him into a tight hug which caused Donna to laugh at us.

"Oi! You three!" Someone called out. Our heads snapped around to see Penny walking towards her. Her back was hunched as she was tied down to the chair with ropes yet again. "You're just mad! Do you hear me? Mad! And I'm going to report you for… Madness." And with that she scuttled away, probably to find someone that could get her out of those ropes.

"You see, some people just can't take it." Donna said. Both the Doctor and I nodded our heads.

"No." The Doctor voiced his agreement.

"And some people can," She added, her voice becoming bright and higher pitched. "So then. TARDIS. She grabbed hold of both and mine and the Doctor's hands and dragged us along. "Come on!"

XOXO

We walked through the alleyway, the Doctor in front as we headed to the TARDIS. However, Donna suddenly stopped. "That's my car!" She cried in delight. "Oh that is like destiny!" She moved over to her car, opening the boot of it, revealing a load of packed suitcases. "And I've been ready for this. I packed ages ago, just in case. 'Cause I thought, 'Hot weather. Cold weather. No weather. He goes anywhere. I've got to be prepared.'" She piled a load of suitcases into his arms as she talked, shoving one last box on top.

"You've got a… a… hat box?" The Doctor asked, slightly bewildered.

"Planet of the hats, I'm ready!" Donna exclaimed. I laughed slightly, grabbing the hat box and another bag off of him, lugging them over to the TARDIS along with him. "I don't need in injections, do I? You know like when you go Cambodia, is there any of that? 'Cause my friend Veena went to Bahrain and she…" She stopped suddenly realizing the silence that was coming from the Doctor's mouth. "You're not saying much."

"He's in shock." I told her. "The whole companion thing doesn't usually go this way."

"It's just…" The Doctor sighed. "It's a funny old life, in the TARDIS."

"You don't want me…" Donna's tone and gone down by a drastic amount and her expression had saddened.

"I'm not saying that." He defended.

"But you asked me." She looked from the Doctor to me and then back to him again. "Would it you rather it be you two on your own?"

I shook my head. "No."

The Doctor also shook his head. "Actually, no." He trailed off; trying to find a way to explain whatever was on his mind. He dropped the bags down on the floor before speaking up again. "The last time, with Martha, like I said, it… It got complicated. And that was all my fault…." He sighed again. "I just want a mate."

"You just want to mate!" Donna cried in disgust.

The Doctor's head snapped up, horrified and instantly tried to correct her. "I just want a mate."

"You're not mating with me, sunshine!" She stepped back and tried to shield herself behind to door of the TARDIS. "Mate with her or something!" She pointed over at me, which caused both the Doctor and I to send disgusted look at one another.

"A mate!" The Doctor corrected again. "I want a mate!"

"Well, just as well, because I'm not having any of that nonsense." Donna said as she stepped back out. "I mean you're just a long streak of nothing. You know, alien nothing."

I smiled slightly while the Doctor nodded. "There we are, then." The two of them nodded. "Okay."

"I can come?" Donna asked. The hopefulness was clear in her voice and her eyes.

"Yeah. Course you can, yeah." The Doctor nodded and grinned. "I'd love it." His head turned to me, waiting for my confirmation.

"You already had my vote!" I grinned as well.

Donna exclaimed happily. "That's just…" Words failed her. She flung her arms open to hug as and both the Doctor and I done the same, but she suddenly seemed to stop, realizing something. "Car keys!" She cried, digging her hands in her pocket.

"What?" I frowned.

"I've still got my mum's car keys." She said, waving them in my face before sprinting off. "I won't be a minute!" She called, leaving just me and the Doctor to carry all her stuff inside.

XOXO

3rd Person POV

Donna walked out of the alleyway, her phone pressed to her ear as she tried to speak to her frantic mother who was on the phone. "I know, Mum, I saw it. Little fat people. Listen, I've got to go. I'm staying with Veena for a bit."

"But it was in the sky…" Syliva's bewildered voice came down the line.

"Yeah, I know. Spaceship. But I've still got the car keys." She was silent for a moment before she suddenly came up with an idea. "Look, there's a bin on Brook Street about 30 feet from the corner. I'm going to leave them in there." She chucked the keys into the bin, thudding as they hit the bottom.

"What? A bin?"

"Yes, I said 'bin'."

"But you can't do that—"

"Oh, stop complaining. The car's just down the road a bit. Got to go. Really got to go. Bye."

"But, Donna you can't—"

Donna hung up the phone before Sylvia could even finish her sentence. She looked around the place for a moment catching sight of two blondes. One was a man, his blonde hair spiked up messily in all sorts of directions, wearing a simple pair of black skinny jeans, a white shirt and black leather jacket. The other was a woman; her blonde hair was left down straight, wearing a pair of black trousers, a dark pink top and purple leather jacket. Donna rushed over to them. "Listen!" She called out to them. The two blondes turned. "Listen, there's this woman who's going to come along, a tall blonde woman called Sylvia. Tell her, 'that bin there.' All right? It'll all make sense. 'That bin there'."

"Oh, uh, sorry." The man spoke up, his accent telling her he clearly wasn't from London. More like somewhere up north. "We were just here looking for some friends of ours. But it turns out they're not here." He smiled sadly. "And we should be on our way so…"

"I'd go tell one of the police or the journalists." The woman suggested, her accent showing she was most definitely form London. "You'll be able to count on them. They're going to be here a while."

"Yeah." Donna smiled at them as she began walking away. "Thanks anyway." She went up to one of the journalists that had turned up, desperately trying to get a report. She repeated exactly what she had said to the two blondes before walking away. She turned around looking back at the scene for one last moment. The two blondes were gone, leaving the police, journalists and a couple of onlookers.

XOXO

Katherine's POV

"Off we go, then!" Donna said as she stepped into the TARDIS.

"Here it is, the TARDIS." The Doctor began introducing. "It's bigger on the inside than it is on the outside."

"Oh, I know that bit." Donna stopped his, waving it away with her hand. "Although frankly, you could turn the heating up."

I laughed and shook my head. "You don't know how many times I've said that to him."

The Doctor pouted for a moment before letting the interruption pass. "So… Whole wide universe. Where do you want to go?"

"Oh, I know exactly the place." Donna said.

"Which is?" I asked, leaning against one of the pillars with a raised eyebrow.

"Two and a half miles that way." She said with a nod in the direction she wanted to go.

XOXO

The Doctor complied with Donna's request. We flew across London until we were just above a hill. Donna fled down the ramp to the doors and opened them, waving enthusiastically.

"That's my Donna!" I heard someone call out. Both me and the Doctor joined Donna by the doors, only just seeing the elderly man who Donna was waving at, standing by a telescope. He pointed up at us, getting more excited by the moment. The Doctor and I smiled sheepishly, waving at him. We only just caught him doing some funny little dance. Then the TARDIS doors closed and we zoomed off. Into time and space.

XOXO

Authors Note: And back to the Doctor Who episodes! This chapter was extremely chunky. The episodes rather fast paced so… I hope I fitted Katherine in all right. I tried my best.

It appears that Rose is now back. But the big question is… who was that second blonde man that was with her? All will be revealed in later chapters, and I mean later ones. Although, you will get a few more hints a little sooner. You have no idea how excited I was to write just that bit to be honest. Things are going to get interesting, I promise you.

Oh and Katherine has her own sonic now. I don't know, I just felt the pen went to waste. And the Doctor likes giving her presents so there you go. You might see her wander off and use it to get herself out of sticky situations herself now. You never know. ;)

This may be the last chapter for a while. I'm on half term, but I have two exams ending two of my GCSE course in June on the 13th and 14th, then I have a Maths mock on the 19th. So some time after that you may get the next chapter. I have work experience on the first week of July, but that won't get in the way too much I don't think.

Let me know what you think of the chapter, how the blonde man is, whatever! I like to hear everything. Also what did everyone think about The Name of The Doctor? John Hurt… wow.

Also, don't forget I made a blog on tumblr. The username is "thekatstewartseries" or you can just use the link on my profile.

Until the next time.:)
