They stand and watch as Lazarus pose in front of photographers getting fawned over by the rich snobby crowd, Fallon shakes her head as she watches people touch him, something about it all makes her feel sick, so she turns back as she watches the doctor examine the chamber surreptitiously.

this is wrong.. just wrong.

"It can't be the same guy" Martha murmurs to them, she leans on one of the chambers columns as she leans in closer to the doctor "It's impossible. It must be a trick."

The doctor looks up at Martha and mutters back darkly "Oh, it's not a trick. I wish it were."

Martha frowns "What just happened then?" The doctor is quiet for a moment his voice sounding hollow as he starts to speak "He just changed what it means to be human."

we got that doctor.

Fallon has seen a lot of things in her time, dark horrible things, things that would make you shiver, been to places that were the stuff of nightmares, she knows that sometimes because you can do something doesn't mean you should do it.

"Yeah maybe he has, but this is going to go abysmally wrong and others are going to get hurt for something so dumb like youth" Fallon says as she watches Lazarus across the room.

The doctor watches Fallon as she speaks he reaches to touch her arm in comfort and she pulls it away.

she wishes he would stop doing that, stop being so familiar with her, when she isn't with him.

The doctor sighs and frowns but he accepts her pulling away from him.

They watch as Lazarus stiffens and gasps, as he moves his body in an awkward way and suddenly grab a tray from a passing waiter and starts to proceed shovelling the food on it down his throat, the old rich hag from earlier watches him with shock.

Now thats not normal..

With that cue the doctor heads towards him "we need to talk to him come on" Martha follows him like a well trained subject.

Fallon rolls her eyes and grudgingly follows after them.

not because she wants too, only because she needs him to get her back home or she will die trying.

Just as the approach they hear Lazarus say "I'm famished."

"Energy deficit." The doctor informs him, Lazarus looks at him curiously as the doctor continues "always happens with this type of process"

Lazarus notes "You speak as if you see this every day, Mister..?"

"Doctor." The doctor supplies before adding "And well, no, not every day, but I have some experience of this kind of transformation."

Lazarus scoffs at him "That's not possible."

Fallon rolls her eyes at his ignorance, the doctor not one to be beat, rattles off at him "Using hypersonic sound waves to create a state of resonance. That's inspired."

Lazarus was surprised but that soon faded in to suspicion "You understand the theory, then."

Fallon notices the doctors look grow darker as he speaks his voice completely flat with disapproval "Enough to know that you couldn't possibly have allowed for all the variables."

Lazarus gives him an unbothered look "No experiment is entirely without risk."

The room temperature drops and so does the doctors face into something even darker.

Fallon contemplates whether she should step in he's not all light and fun all the time it seems.

"That thing nearly exploded." The doctor said darkly. "You might as well have stepped into a blender."

The rich hag from earlier snaps at the doctor You're not qualified to comment."

She was glaring at the doctor with cold hard look.

Her look rubbed Fallon up the wrong way, and Fallon can't help but snapping back for some reason "If he hadn't stopped it, it would of exploded! Probably killing everyone in this room and then there would be a problem" The doctor rest his hand on Fallon to calm her down and she brushes him off annoyed.

The doctor glanced at her to say something when the Lazarus butts in giving her a look of interest which makes Fallons skin crawl "Then Thank you doctor" he said silkily but certainly not sincere.

"But that's a simple engineering issue. What happened inside the capsule was exactly what was supposed to happen. No more, no less."

"You've no way of knowing that until you've run proper tests." Martha decides to interject without missing a beat.

Lazarus gives a slimy smile "Look at me. You can see what happened. I'm all the proof you need."

The rich hag starts to speak again and her voice starts to grate on Fallons last nerve "This device will be properly certified before we start to operate commercially." Fallon goes to say something snappily back but stops when the said woman in front of her form changes to a skeleton looking from before changing back.

Fallon blinks what the hell?

"Commercially? Martha says incredulously. "You are joking. That'll cause chaos."

"Not chaos, change." Lazarus corrects them. "A chance for humanity to evolve, to improve."

The doctor scowls at that "This isn't about improving. This is about you and your customers living a little longer." The doctor spits back getting more worked up the more Lazarus speaks.

Lazarus smirks "Not a little longer, Doctor. A lot longer. Perhaps indefinitely."

The rich hag from before sharply interjects "Richard, we have things to discuss, upstairs."

Lazarus nods "Goodbye, Doctor. In a few years, you'll look back and laugh at how wrong you were."

Doubt that very much..

He takes Martha's hand and presses a kiss to it before turns to take Fallons.

Fallon puts her hands behind her back and sneers at him "like I would let you touch me"

He gives Fallon a smirk eyeing her up and down "hm.. you are something" The doctors hand balls in fist at the way he's looking at her, Lazarus gives them one last look and then walks away.

"Oh, he's out of his depth." The doctor mutters to them before adding in "No idea of the damage he might have done."

Martha turns to her eagerly "So what do we do now?" She asks him.

"Now? Well, this building must be full of laboratories. I say we do our own tests." The doctor tells her.

Martha pauses and then looks down at her hand before saying to him "Lucky I've just collected a DNA sample then, isn't it?" The doctor beams brightly at her "Oh, Martha Jones, you're a star." Martha smiles back it shouldn't but feels really good to get his praise she thinks.

"I'm going to stay here in the reception room" Fallon states to him.

She needs to take a step back it's been all go.

The doctor and Martha both freeze at that

"What?" The doctor questions.

"Look, it doesn't take all three of us to go to laboratories, I don't need to be stuck at your side, anyway that stuff isn't a strength of mine" Fallon mutters out a little.

The doctors eyes soften a little "Lovely... I know what you are good at, I just wanted you too be with me, and well you are also early and still getting used to everything"

Fallon sighs "Look I get you keep saying that you know me and that you trust me, but just back up a little and let me think"

Oh crap Fallon that was a little harsh..

She feels even worse at the hurt look in his eyes before it's gone and he sniffs "okay, consider this me backing off a little, we won't be long" The doctor says as he turns around, he gives her one last look before he walks on with Martha.

well now she awful.

She considers going after him... crap how stupid is it..that she's feeling bad for upsetting someone she doesn't even know?.

She stares down at the glass she's nursing in her hand when she feels something brush up against her mind, a weird feeling, something she hasn't had before, it wasnt awful, it almost felt intoxicating..she takes a shaky breath when the feeling disappears.

She suddenly hears a new voice behind her "you look happy so to be here, not enjoying the event?"

Fallon turns around and finds a man standing behind her in a black suit, but something in his eyes stand out to her "I'm sorry do we know each other?"

He gives her a smirk "not yet... Harold... Harold Saxon, it's such a pleasure to meet you..." He says taking her hand in his and he presses a kiss to it.

"Yeah nice to meet you, I'm Fallon"

"You don't recognise me, I'm currently running for Prime minister, such a shame what happened with the old one right? Harriet Jones started out so well" He says mockingly he grins even more when he sees her confused look "don't pay enough attention to politics?"

Fallon shakes her head and looks at him suspiciously, there's something about him "sorry kind of... new to the area you could say"

Saxon laughs a little "Mmm new too the area yes you are"

Fallon notices the way he says it, is like he knows more than what he is saying.

"You know I'm surprised he left you on your own especially how fine you look in that dress, he never does appreciate what he has" He says to her with a good amount of disdain.

His comments catches her attention "I'm assuming when you say He, you mean the doctor? I take it you know each other?" Fallon asks him curiously.

who is this man, she cant help feel intrigued by him..

"You could say we go way back, though I wouldn't mention our little meeting to him just yet.. timelines and all, wouldn't want to break the doctors precious codes now would we? Then again he's keeping a lot from you already isn't he?" He says to her grinning a little.

"You just expect me to take the words from someone I just met, I don't trust you, there's something about you..." Fallon spat out at him.

Saxon just laughs again and leans in closer to her taking in her scent and he tries to brush against mind a little harder this time, making her step back a little she puts her hand to her head as it pulses a little with an odd beat.. "I know you aren't going to say anything yet... I just know..don't worry Fallon it was all be clear in due time... I'm looking forward to seeing you again, that when the fun will begin" he grins at her manically before walking away from her.

Fallon watches him walk away, having the feeling that nothing good is going to come from him in the future.

The odd pulsing beat in her head stops, it was like drums .. weirdly enough .. she needs to remember and ask the doctor about it later.

She turns and decides to go find The doctor and Martha this time, she starts to walk through the hallways of the laboratories.

god damn it they got to be somewhere around here.

She's not paying attention when she walks around the corner and literally runs into someone, she gets that much of a fright she pushes the person up against the wall hard.

"woah woah Fallon... lovely it's me, what's wrong" The Doctor exclaims quickly.

Fallon quickly let's him go "oh sorry doctor, I didn't realise it was you sorry"

He gives her a concerned look "it's fine really... are you okay?"

Fallon gives him a quick nod "yeah I'm fine, you keep saying I can trust you, that we are close, but I don't feel that right now, I mean are you hiding things from me purposely or because you can't because of timelines or whatever?"

The run in with Harold Saxon has made her slightly paranoid

He frowns a little at her questions especially at the part where she doesn't believe or trust him.

He sighs and reaches out to touch her face but stops himself "You can trust me full heartedly, I know you aren't there yet and that's okay, but I just need you too know I would never purposely hide anything from you and I would never hurt you" he gives her a sad smile.

She returns his smile with one of her own, "I'm trying, really I am but it's hard, I'm thrust into a new universe I don't know and my biology is slowly changing and it's feels too much and hard, and that's coming from someone who's been up against demons, death and hell"

The doctor gives her a tender smile "I know and you Fallon Winchester is one of the most strongest and most stubborn person I know and you will get through it I promise"

Fallon takes in his words and wants to believe them so badly.

She gives him a nod, just as Martha runs towards them "Doctor his genes have changed again"

The doctors eyes widen and he rushes after her and Fallon follows them "his genes have what?" She asks them.

She stops when the doctor stops in front of a computer screen,with what she can understand is a gene sequence.

that's as far as scientific she goes, she better add that on to the list of research

She stares at the screen when the gene sequence changes then flips back "what's going on? Can you explain please? That just changed is it supposed to change?" Fallon asks them

Martha shakes her head "it means Lazarus has changed his own molecular patterns."

The doctor explains further "Hypersonic sound waves to destabilise the cell structure, then a metagenic programme to manipulate the coding in the protein strands."

Fallon and Martha both this time give a confused look, and he sighs "Basically, he hacked into his own genes and instructed them to rejuvenate."

Martha points to the screen "But they're still mutating now, he's made a mistake somewhere?"

"Well more like he's missed something, Something in his DNA has been activated and won't let him stabilise. Something that's trying to change him." The doctor says to them in a low voice.

Fallon frowns a little thinking about her own biological DNA changing "is that like what's happening to me?" She decides to ask him.

He glances at Fallon and shakes his head "no no completely different" he says trying to reassure her as much as he can.

Martha jumps in and changes the subject "okay but what is he changing into?" The doctor shrugs "I don't know, but I think we need to find out."

"That old rich Ha- woman said they were going upstairs" Fallon says changing her words to a more polite answer after the other twos looks. "Let's go the doctor orders as he moves for doors and the girls follow behind him.

They step out of an elevator and switch on the lights, the room is filled with screens and art and a large mahogany desk with beautiful carved symbols on it "This is his office, all right." Martha commented quietly.

Fallon agrees "yeah pretentious dick written all over it" surprisingly this time the doctor doesn't comment on her use of language, he can't disagree with it.

So where is he?" The doctor muses as he walks further into the room, "Don't know. Let's try back at the reception..." Martha begins to say before she trials off when she sees a skeletal leg with a ladies shoe on it sticking out behind the desk, she gasps and quickly rushes over to the desk, the doctor and Fallon follow only stop when the see what Martha has found, it was a mummified corpse, in a fancy black dress.

the same woman from earlier the same woman Fallon kept getting flashes of earlier, is this her fault? Could she of stop this? The woman sounded awful but she didn't deserve that.. was she too distracted with being here and this has now happened.

The doctor sees the way Fallon was staring, he nudges her back a little and gives her a small reassured smile.

He knows he said he would back of a little but he needs her to know what ever she is thinking or knows, he's always got her back.

She looks at him and gives him a small smile back that she appreciates his attempt.

"Is that Lady Thaw?" Martha asks quickly.

oh so thats her name, she didnt even learn that.

"Used to be. Now it's just a shell." His voice a little too curious for Fallons liking. "Had all the life energy drained out, like squeezing the juice out of an orange."

"Lazarus?" Martha queries.

Fallon looks away from the corpse "what else could it be" Fallon asks her brow still furrowed.

Doctor nods in agreement "Could be."

"So he's changed already?" Martha asks full of dread at the answer.

"Not necessarily." He shakes his head "You saw the DNA. It was fluctuating. The process must demand energy. This might not have been enough."

"So he might do this again?" Martha asks him seriously, the doctor just hums with the possibility, "Mmm."

Martha sighs and scampers to her feet rushing out the room, the doctor is quick to follow, but Fallon has remained rooted to the spot staring at the corpse a second too long as the doctor comes rushing back in.

Shes seen many horrible things, she doesn't understand why this is affecting her so much..

"Fallon!" He calls running back over to her "come on, I promise we can talk about this later and whatever else that's on that lovely mind of yours"

He holds out his hand and she stares at it before she nods and takes his hand and they rush out the room and into the lift with Martha.

"What do you think he will do next?" Martha asks them while they wait for the lift to stop, The doctor shrugs "well if it's life energy he's after then probably his next victim" Martha gulps at the thought "and after that, will he even stop?"

"Honestly I don't think he will ever stop" The doctor answers back and Fallon sighs, her jaw tenses and adds "that's why we need to stop him and fast" before stepping out the lift and looking around the Reception.

"I can't see him." Martha calls to them over all the chatter and music playing.

"He should be easy to spot if he was here" Fallon says back as loud as she could.

the doctor squeezed her hand and nods "He can't be far. Keep looking."

"Hey, you all right, Marth? I think Mum wants to talk to you." Martha's brother says appearing in front of the three of them, the doctor and Fallon decide to leave her to her brother and continue to scan the room.

Have you see Lazarus anywhere?" Martha asked her brother.

"Yeah, well, he was getting cosy with Tish a couple of minutes ago." Leo tells her with a smirk

Martha gives a horrified look as the doctor and Fallon come back over their search unsuccessful "With Tish?" she asks her brother anxiously.

When Martha's mother comes storming up to them like a mad woman on a mission "Ah, Doctor. Fallon"

"Where did they go? " The doctor snaps at Leo ignoring Francine, he has no time to pacify anyone at this time, Fallon doesn't answer the woman either.

"Upstairs, I think. Why?" Leo asks innocently, the doctor grabs Fallons hand and doesn't explain anything he runs past Francine, spilling her drink as he does, Fallon winces a little as he pulls her along by the hand.

"Doctor- I'm speaking to you!" Francine hollers at them , appalled by the lack of manners.

Martha sighs "Not now, Mum."

"That was a little rude doc" Fallon mutters at him as they get in the lift, he glances at her and scoffs a little "sorry Lovely.. but manners are a little low on the list right now don't you think?"

Martha joins them "is he going to do to Trish what he's done to that lady Thaw?"

He looks at her "do you want the truth or a reassuring answer?"

Martha gives him a dry look "the truth"

"Then yes he is"

Martha glances away crossing her arms over to hide her trembling fingers at the thoughts going through her head, Fallon reach out and gives her arm a squeeze "It's not over yet, so don't think those thoughts okay?"

Martha gives a nod and they step out the lift and into Lazarus office, but it's still empty.

"Where are they?" Martha demanded looking around.

"Fluctuating DNA will give off an energy signature. I might be able to pick it up." He says as he pulls out his sonic screwdriver and starts to scan, it lights up and makes a noise "Got him."

"Where?" She asks him anxiously, worried about her sister, he answers by pointing upwards "But this is the top floor." Martha argues.

"Yeah but what's higher than the top floor?" Fallon asks her raising an eyebrow.

"The roof." Martha gasps.
