I've got plans. Like plans that won't see the light until after the finale. Maybe after the finale then before Donna but I'm completely undecided. I'll use it when the time comes.

"Doctor," Charls sauntered around the console as he parked a place closer to the event, "Do you happen to have a suit? Or maybe a dress? I'm not sure if jeans are the best thing for a formal event. Wait! Is this a formal event?"

Martha nodded, "Yes, it's formal. Black tie and all that...stuff."

Charls face lit up, "Black tie! Can I wear a tie?"

The Doctor smirked, "There's a whole wardrobe. Not really sure what's in there now."

Charls jumped off of the platform and ran down a corridor without another word.

"I suppose I should get changed, too." The Doctor sighed and walked to the wardrobe.

"Ugh, black tie." The Doctor sighed, fixing the cuffs of his suit, "Whenever I wear this, something bad always happens."

He and Martha walked down the sidewalk at a regular pace, while Charls was skipping around and looking at buildings. They seemed to enjoy the new sights that they'd forgotten about. Earth. London. Home. Or at least, what used to be home.

"Ah! There's that place I passed by that one time I went to buy a sandwich but got lost!" They exclaimed and pointed at a streetlight." They sighed happily and bounced back to Martha's side, "This new brain really is magnificent for remembering things. Much easier to read books rather than search around in the dark inside a box."

Martha smiled at them then went back to talking with the Doctor, "It's not the outfit, that's just you. Anyways, I think it suits you. In a James Bond kind of way."

"James Bond?" The Doctor sounded slightly offended, "Really?"

Charls frowned, "Who's James Bond?"

Martha looked shocked, "You don't know who James Bond is? The whole library in your brain and you don't have a book about James Bond?"

Charls closed their eyes and ran through a few books then opened their eyes again, "Nope! So are you going to tell me?"

"He's a character in a spy movie series." Martha said simply.

Charls tilted their head, "James Bond wears a bow tie?"

"Yeah." Martha nodded, "James Bond wears a suit and bow tie."

Charls examined their outfit then looked at the Doctor, "Do you think I'm underdressed for this event?"

Charls was wearing black suit pants, a white collared shirt, and an unbuttoned waistcoat. Their shoes looked worn down and weren't dress shoes but rather combat boots. The waistcoat seemed strange at a certain angle, it shimmered with all the colors in the world but maybe it was just the light that made it look like that for a split second.

"The shoes, maybe." Martha examined Charls, "Are you going to button the waistcoat?"

Charls shrugged, "It feels too suffocating when I button it."

They approached a building with the words 'LAZARUS LABORATORIES' above the entrance.

"I don't suppose a plus 2 is allowed?" Charls commented as they crossed the street.

The Doctor paused, "I suppose not."

"Then how are all three of us supposed to get in?" Martha asked as they approached the stairs.

Charls whispered, "I read a book in my library so I'll meet you inside. Trust me."

Before Martha or the Doctor could protest, Charls quickly skipped up the steps and disappeared into the crowd. The two stood at the top of the stairs, looking for Charls. It was almost like they'd disappeared into thin air. Again.

"Well, they said to trust them." Martha pointed out and walked into the building.

Charls P.O.V. (to be honest, I like writing from Charls' view because it's not just repeating script but I'll try to not use it too much. maybe.)

I took a deep breath and broke away from Martha and the Doctor. I remembered what I'd read in the book I found. Think that people cannot see you. Blend in. You aren't noticeable and you cannot be found. Believe that and it will be true. I felt the looks of the people around me fade away. I glanced behind me, the Doctor and Martha had made it in successfully and were meeting up with who seemed to be Martha's sister.

I passed by a server holding a tray of food, little crackers with some sort of cream on top. It's like sushi but crackers! I found myself following the plate of crackers so I decided that it wouldn't harm anyone if I just took one. I straightened my jacket and strolled casually to the waiter, snatching up a snack before anyone could notice.

I smirked, I'm brilliant. It's like I'm invisible! I shoved the little sushi cracker into my mouth and wiped my hand across my face. Now, there's obviously something very fishy around here.

I danced around the people, avoiding bumping into anyone so I wouldn't get caught. Eventually I made my way back to the Doctor, staying hidden, of course. I put my back to his so he'd know I was there but I didn't make myself visible yet.

His expression only shifted slightly, "Charls?"

"Yeah?" I whispered back, "What do you think?"

He straightened up and shoved more crackers in his mouth, "You're invisible!"

I elbowed him, "Quiet!"

Martha's sister looked at the Doctor funny then carried on, "Is he with you?" She asked Martha with a stiff smile.

Martha nodded, "Yeah."

"But he's not on the list. How'd he get in?" Her smile began to frown at the corners.

Martha shifted her weight from one foot to the other, "He's my plus one."

I elbowed the Doctor again, urging him to speak and ask questions rather than eat finger food.

He jumped into the conversation, "So, this Lazarus, he's your boss?"

Martha's sister turned to him, "Professor Lazarus, yes. I'm part of his executive staff."

Sounds a bit stuck up to me. I huffed and kept my back on the Doctor's. Sorry, Martha.

Martha sounded like she rolled her eyes, "She's in the PR department."

Her sister sounded very offended, "I'm head of the PR department, actually."

I whistled. Proud girl. Probably smart, too. That time the Doctor elbowed me back, I rolled my eyes and kept quiet.

"You're joking."

"I put this whole thing together." The sister said proudly.

"So do you know what the professor's going to be doing tonight?" Doctor pushed a little on my right side before he turned around fully. "That looks like it might be a sonic microfield manipulator."

I barely had time to react, stepping and turning in sync with the Doctor.

"He's a science geek. I should have known." Martha's sister sounded like she knew everything, "Got to get back to work now. I'll catch up with you later."

I heard her walk away so I stepped out from behind the Doctor but decided to stay invisible.

"Science geek? What does that mean?" The Doctor asked as Martha watched her sister walk away.

"That you're obsessively enthusiastic about it." Martha informed him.

The Doctor smiled and wagged his head, "Oh, nice."

"Personally, I think that he's just being a smartass and likes to show off." I joked before running off, noticing that they had company incoming.

Martha's eyes widened, "Was that-"

The Doctor cut her off, "Yes, but we'll get to it later."

I circled around the giant, white rectangle that stood in the center of the room. It seemed to look completely normal but I couldn't help but feel that something was off. Stupid Gray. Giving me pieces but no way to complete the puzzle. I huffed and walked up the stairs to get an aerial view. I snickered as I saw the Doctor being very awkward around Martha's mother.

I nearly fell down the stairs as an old man, Lazarus apparently, tapped a glass to get everyone's attention. I'm way too jumpy. Have I always been jumpy? I thought about it for a minute before deciding that yes, I have always been jumpy. I shook my head and focused on Lazarus.

"Ladies and gentlemen, I am Professor Richard Lazarus and tonight I am going to perform a miracle. It is, I believe, the most important advance since Rutherford split the atom, the biggest leap since Armstrong stood on the moon. Tonight, you will watch and wonder. Tomorrow, you will wake to a world which will be changed forever."

I leaned against the handrail of the stairs as he spoke, This man gives me the creeps. At that moment I decided to, at one point in the night, punch Lazarus in the face. I frowned, Why am I going to punch him in the face? Am I violent!? I realized with shock. I'd never been one for violence but there was something about that man that made me want to punch him or send him flying across the room. I growled then made myself calm down, we were there for a reason.

I perked up as he stepped inside the white rectangle and a few seconds later a really bright light nearly blinded me. I ducked my head then forced my eyes to adjust. It was bad enough that the light hurt by the high pitched screech made my ears ring. The rectangle was then surrounded by electricity and began to spin. A new noise rang above the screeching, an alarm. I looked towards the scientists who were by the computers and saw the red font flash 'System Overload.' I sighed and rubbed my eyes, I hopped over the railing and ran towards the computers.

I guess that the impact of the jump or the flashing lights made me lose my concentration because the Doctor shouted a command at me once he'd reached the computers, too.

"It's overloading." He shouted as I leaped over the desks.

I huffed, "I can see that." The brilliant thing is that I didn't feel a huge burden on my chest as I ran, really a man's chest was way easier to run with. He pointed towards some controls and told me to adjust a few things.

I heard a lady shout at us, "Somebody stop them! Get them away from those controls!"

I waved a hand at her, "We'll go away later."

"If this thing goes up, it'll take the whole building with it." The Doctor looked up at the woman shouting, "Is that what you want?"

I growled and dashed towards the other computers, not exactly knowing what to do but at the same time doing exactly what needed to be done. I stopped and ran over to the Doctor as he jumped over the desk and pulled out a chord. The high pitched whine slowed and faded as the contraption stopped spinning. I relaxed as Martha opened the box and a fog fell out.

I walked over to the steps again, making eye contact with the Doctor. I pointed towards the elevators that would take me to the upper floors. He gave me a small nod then focused on the box. I took a small look at the man exiting the box and kept going, not letting myself get distracted by the magic that just happened. An old man become young again.

I made my way into an elevator before totally rethinking everything aloud. Hopefully no one was nearby to see me go to a probably restricted area.

"Holy shit!" I ran my hands through my hair, thankful that I decided not to gel it back, "Holy shit! That was weird." I watched my hands shake as I examined myself, "That was too weird."

I took a breath, I didn't want to recall the strange force that made me know what buttons to push and how to act. I knew that I wasn't supposed to be able to do that but yet I just did.

"What was that? Why did that happen? It was like autopilot...was it a good thing? I suppose it isn't." I paced in the small area, "Is it a Gray thing or a human thing. Wait. No. According to the books, humans don't have any natural abilities like that, yet. What do you mean yet?" I shouted at myself. "I don't understand! Why do I know these things?"

There wasn't a reply to any of my questions. There would be answers but I wouldn't be able to get them yet, and I was not okay with that. I slammed my hand against my head.

"Cut it out!" I scolded myself, "Focus. No overloading right now. We'll have time for that later."

I put my hand over my heart and took a breath. A shaky breath. I screwed my eyes shut and focused on breathing. After a few minutes, I opened my eyes and concentrated, becoming invisible again. Once I was sure that it was nearly impossible to see me, I stepped out of the lift.

Now to snoop around. I smirked, apparently I liked snooping. I had made my way around the corner when a ding of the elevators caught my attention. How long had I been in the lift? Couldn't have been that long…

I poked my head around the corner and saw Lazarus and the old woman walking towards a room. I followed them, quietly. They were overlooking the view of the city while sharing a drink. I snuck behind the desk they were leaning on and peeked over. He really is young again. That's very strange. I stayed in my place behind the desk, listening.

"A tiny flat above a butcher's shop." Lazarus sounded almost sentimental.

So he has emotions, good to know.

"It'll have a blue plaque soon." The lady sounded extremely snarky, "Richard Lazarus lived here."

"It's gone. Destroyed in the war. The bombing." Lazarus took a sip of his drink.

"Of course."

"1940. Do you remember? Night after night. Explosions, guns, firestorm." I glanced up at the window, looking at Lazarus' face in the reflections. I was surprised to see that he looked sad, but I guess that meant he was still human.

"My parents had sent me to the country by then." The lady noted, for some reason she pissed me off too. Acting like she was something great when really she probably wasn't. Isn't it rude to add comments about your life when someone's recalling their backstory? Humans…

"When the sirens went, we'd go to the cathedral there. We used to shelter in the crypt. The living cowering among the dead."

"But look what you've built here, now. You've laid the foundations for an empire. An empire we can rule together." She pulled Lazarus towards her and kissed him.

Gross, you're the same age but gross. He looks like he's 30 and you're an old lady. I looked away, cringing.

"Well, what's wrong?" She asked, offended.

I looked back at them, Lazarus had wiped his mouth and turned her head towards the window.

"Look at yourself, woman." He said in a low voice.

Rude and rejected. I huffed, of course he wouldn't want to kiss her looking like he did now. Humans are too proud and care too much about their visual appearance. I frowned, I'm human...only two-thirds but still. I hope I didn't gain that portion of their human tendencies.

Meanwhile…

Martha and the Doctor watched as Lazarus' DNA spun around on the computer screen.

"It's impossible." Martha shook her head.

"And that's three impossible things we've seen so far tonight." The Doctor smiled, "Don't you love it when that happens?"

"That means Lazarus has changed his own molecular patterns."

"Hypersonic sound waves to destabilise the cell structure, then a metagenic programme to manipulate the coding in the protein strands. Basically, he hacked into his own genes and instructed them to rejuvenate." The Doctor explained more thoroughly than needed.

"But they're still mutating now." Martha noted.

"Because he missed something. Something in his DNA has been activated and won't let him stabilise. Something that's trying to change him." They watched as the DNA mutated again.

"Change him into what?"

"I don't know, but I think we need to find out."

"That woman said they were going upstairs." Martha looked at him.

The Doctor's eyes widened a little, "Charls is upstairs."

"What!" Martha exclaimed as quietly as she could.

"Let's go." The Doctor ran as quickly as he could to the stairs.
