The Poison Sky

Rose was waist deep in the bonnet, the Doctor was frantically using the screwdriver on the bumper, Donna was furiously tugging at the door handle, and Wilf was slowly being choked by the smoke.

"He's gonna choke! Doctor!" Donna screamed at the Doctor who was now cursing under his breath in Gallifreyan

"It won't open!" He yelled before he slowly moved from the back of the car to see Sylvia's feet rushing to the car with an axe.

"Woah, wait a sec!" He heard Rose shout slightly flinging her small form away from the car as Donna's mother swung the axe over her head and through the windscreen, glass flying everywhere while Rose shielded her face from the onslaught of broken glass. Donna was merely looking at her mother with her mouth hanging open, not having any idea what to think about what just happened.

"Well, don't just stand there! Get him out!" She complained, waving her hand towards her father.

"Thanks!" Wilf said as he was helped by his daughter and granddaughter back into the house. The gas floating all around them while the Doctor and Rose trailed behind them

"I can't believe you've got an axe!" Donna scoffed over at her mum

"Burglars!" Sylvia simply smiled, all the while the Doctor was trying to pull small shards of glass from Rose's hair, and Rose picking the material from her coat, praying it wouldn't break the delicate material.

"Get inside the house. Just try and close off the doors and windows." Rose said to them gently, as she guided Wilf back up the stairs with them a small smile present on her lips.

"Doctor!" Ross yelled from his position in a black Cab. Rose and the Doctor snapping their in the direction of his voice "This is all I could find that hasn't got ATMOS." He finished just too find the Doctor and Rose bounding over to him and climbing into the back of the car before the Doctor shouted over his shoulder to Donna who was still helping her grandfather back into the house

"Donna, you coming?"

"Yeah!"

"Donna! Don't go! Look what happens every time that Doctor appears! Stay with us, please." Sylvia snapped, The Doctor now helping Rose into the car while the Doctor held open the door even further

"You go my darling!" Wilf encouraged pushing her slightly in the direction of her time lord friends

"Dad!"

"Don't listen to her! You go with the Doctor! That's my girl!..." Wilf continued as he watched as Donna got into the car. She simply shoved the feelings of guilt to the bottom of her stomach before she continued to travel with the Doctor. The Taxi finally pulled up the ATMOS factory swiftly after leaving Donna's estate just for the trio to fall out of the car and outside into the gas.

"Ross, look after yourself, get inside the building." The Doctor voiced through the window of the cab while Donna moved away slightly coughing, Rose struggling to breath but it wasn't affecting her as much as Donna

"Will do." Ross said with a smile before talking into his radio "Greyhound 40 to Trap 1, I have just returned the Doctor to base safe and sound, over."

"The air is disgusting!" Donna chocked up at them, her face in a frown, the Doctor and Rose simply looked at her concerned

"It's not so bad for me" The Doctor voice, his eyebrows in a frown, mouth in a straight line "I don't think its effecting Rose that much either" He said as he looked over at Rose who said she was alright, just slightly uncomfortable "Go on, get inside the TARDIS." The Doctor said just as she turned away but cried out slightly "Oh, never given you a key!" He cried happily, pulling out a key from his blazer pocket "Keep that! Go on, that's yours! Quite a big moment really!" The Doctor said quickly and happily.

"Keep it on you at all times" The Doctor said to her in all seriousness "Don't want it falling in the wrong hands" He smiled again, just for Donna to notice Rose pulling at a large chain which was hanging around her neck which held her own key. A smile on her face as she welcomed her officially to the TARDIS. Donna simply coughed slightly, a small smile playing on her lips

"Yeah, maybe we can get sentimental after the world's finished choking to death!" She joked

"Good idea!" The Doctor nodded before taking a few steps away from the pair of them and over to the UNIT factory

"Where are you going?" Donna asked over at him

"Stop a war!" The Doctor smiled as he watched Donna rushing off and he simply turned his attention to Rose "Go with Donna"

"No I'm not leaving you" Rose stated as she looked up at her husband, the Doctor simply smiled at her and placed his hand to her cheek

"Rose, she's upset and worried about her family, she needs you more than I do" The Doctor said to her gently, knowing that she hated to be parted from him, this being the first time they had been separated on an adventure

"Alright good point" She smiled, letting out a small sigh of a laugh

"I knew you would understand" The Doctor said to her again, smiling a small soft smile

"I'm just that good" Rose stated again. She moved onto her tip toes before placing a kiss to his cheek, smiling over at him before running after Donna. The Doctor watching her as she disappeared into the smoke hoping that she would be alright before he walked over to the barrier, ducked underneath it and rushed to the UNIT field base.

"Right then, here I am, good." The Doctor bellowed when he shoved himself through the glass door and into the base, Mace looking at him in shock slightly while the Doctor continued to talk to them quickly "Whatever you do, Colonel Mace, do not engage the Sontarans in battle, there is nothing they like better than a war. Just leave this to me." He finished quickly, talking right over to Mace who looked up at him open mouthed

"And what are you going to do?" He asked bewildered

"I've got the TARDIS, I'm gonna get on board their ship." He voiced before walking over to Martha, something not right with her, Rose looking into his memories via their connection, he smiled to himself slightly at his wife's words of caution

"Come on!" The Doctor whispered gently as the pair of them walked from the base, the Doctor patting Mace's shoulders in the process. They walked from the factory and rushed down the alleyway the TARDIS had been parked for him to find it gone. He looked at the place it had been parked before he turned around towards Martha. His heartbeats beating quickly in his chest as he realised his Wife was in trouble. Donna too, but he knew deep down in his chest that Rose could look after herself, but it didn't stop him worrying.

"But... where's the TARDIS?" Martha bellowed

"Taste that, in the air." The Doctor muttered, holding his head in the air, his hand held up to his shoulder level "Yecch. That sort of metal tang. Teleport exchange." The Doctor complained, rubbing his fingertips together slightly as he walked back to the entrance of the alleyway "it's the Sontarans, they've taken it. I'm stuck, on Earth like... like an ordinary person. Like a human! How rubbish is that! Sorry, no offence, but come on!" The Doctor rambled, a huge frown on his face as the realization dawned on him. Stuck on earth without his wife and best friend. Great just great.

"So what do we do?"Martha inquired as she took a step towards the Time Lord

"Well... I mean it's shielded, they could never detect it." The Doctor said as he stared down at her

"What?" Martha snapped, taking in the Doctors raised eyebrows, mouth open slightly. Knowing that any human would be coughing and choking... Martha wasn't.

"I'm just wondering, have you phoned your family and Tom?" The Doctor questioned his face being angled so he was looking down at her

"No, what for?" Martha said slightly confused

"The gas. Tell them to stay inside." The Doctor pointed out

"Course I will, yeah, but, what about Donna? I mean, where's she?" Martha said raising her voice slightly, rolling her eyes

"Oh, she's gone home. She's not like you, she's not a soldier." The Doctor smiled slightly as he moved his head away from Martha and then looked back at her

"And Rose?"

"She's with Donna, I was worried that Donna was upset so I asked her to stay with her, Rose is better at that sort of thing. Right. So, avanti!" The Doctor chimed before both Martha and the Doctor bolted from their spot.

Rose and Donna had made it back to the TARDIS safe and sound. Rose watched as Donna coughed up the remain particles of the gas, she was rubbing her back gently as she realised how vulnerable the young woman truly was.

"Thanks" Donna managed to croak out when she had finished

"Not a problem" Rose smiled over at her. But as Rose walked up to the railings and the console the whole of the TARDIS shifted. Rose had to balance herself somewhat by grasping hold of the console, she frowned up at the ceiling as she tried to rake her mind with the conclusion of the disruption. Donna however had her mouth hanging open, her hands clinging onto the railings as she looked over at Rose.

"Well that's not good" Rose muttered to herself slightly before she went to look over at the console screen of the TARDIS. The ancient machine humming in the back of her head as she spoke to the young time lady.

"What do you mean? What's going on?" Donna asked quickly, panic rising in her body slightly as she took cautious steps over to Rose.

"We've moved, parked somewhere else. These co-ordinated are not the ones I imputed this morning" Rose voiced as she looked at the screen over and then to Donna. The red head simply walked over to Rose and looked down at the screen not knowing how to read the Gallifreyan symbols.

"How?" Donna asked over to Rose again

"The Sontaran's have teleported us" Rose read, her eyebrows in a frown as she studies the screen

"But we didn't feel anything" Donna voiced shaking her head slightly

"That's the clever thing about it. The TARDIS has dampeners which make a flight less bumpy" Rose said smiling up at Donna slightly, Rose started to flick around the TARDIS console, readjusting certain settings while Donna moved up to the central column.

"Not what I would call it" Donna muttered which caused Rose to smile over at her slightly before she went back to her work, still talking over to Donna

"That's because she normally has about 7 pilots, was a hell of a lot worst when it was just the Doctor. But you have me, so we should be able to fly her back down to earth. You might want to hold on to something" Rose smiled over to Donna, still adjusting settings on the console, but when she released the handbrake nothing happened. Rose's face moved into a frown as she realised the TARDIS was completely unresponsive "Well that's not good" Rose mumbled to herself

"What? What's happened?" Donna expressed again while Rose went back to the screen, pressing buttons on the side which caused the console to bleep at them slightly, Rose moving her face closer to the monitor as she tried to understand the writing in front of her

"They've placed a force field around that TARDIS which is acting as a scrambling device, exciting particles and the time vortex, she can't dematerialise!" Rose complained as she leant back from the screen one of her hands going to her hair as she itched her head as she tried to think of something to do.

"So what do we do" Donna asked

"We try to see what they're doing outside" Rose said with a sad smile before bringing up the footage of the outside looking at the Sontaran's rejoicing with their prize, enjoying and taunting the Doctor and his marvellous machine.

The Doctor and Martha emerged back through the doors of the UNIT base. Martha following closely behind the man in front of her as he flung his brown trench coat from his form and onto a neighbouring chair

"Change of plan!" The Doctor said loudly as he walked back over to Colonel Mace's side

"Good to have you fighting alongside us, Doctor."

"I'm not fighting, I'm not-fighting, as in not hyphen fighting, got it? I'm trying to save my wife." The Doctor held darkly before going around the console "Now, does anyone know what this gas is yet?"

"We're working on it." Martha said aloud

"It's harmful, but not lethal until it reaches 80% density. We're having the first reports of deaths from the centre of Tokyo City." A young woman settled from the consoles in front of the Doctor.

"And who are you?" The Doctor asked as he leant up against the back of her chair

"Captain Marion Price, sir. " The Captain chimed as she placed her hand in a salute

"Oh, put your hand down. Don't salute." The Doctor sighed before walking away from her, his hands firmly placed in his blue suit pockets.

"Jodrell Bank's traced a signal, Doctor, coming from 5000 miles above the Earth. We're guessing that's what triggered the cars." Mace stated as he brought up a computer image of a red light orbiting earth.

"The Sontaran ship." The Doctor whispered as he continued to flick switches on the console, his eyes flickering towards the screen, his mind falling back on itself making sure his wife was alright.

"NATO has gone to Defcon One, we're preparing a strike."

"You can't do that, nuclear missiles won't even scratch the surface. Let me talk to the Sontaran's."

"You're not authorised to speak on behalf of the Earth".

"I've got that authority, I earned that a long time ago." The Doctor retorted before he used the sonic screwdriver to connect the UNIT systems to the Sontaran ship " Calling the Sontaran Command Ship under Jurisdiction Two of the Intergalactic Rules of Engagement. This is The Doctor."

Rose snapped her head in the direction of the voice that was embedded into her mind. The transmission the Doctor was sending to the Sontaran's was also being received inside the TARDIS. For a split second Rose had a flash of an image of herself springing to her mind. She simply placed her hand to her head and shook it away slightly, not really paying much attention to it. Donna came to stand next to her as they watched the Doctor calling from the UNIT base

"Here we go" Rose breathed slightly as she smiled over at Donna who was smiling gently over to her.

"Doctor, breathing your last?" Staal taunted while he took a few steps towards the image of Rose's husband.

"My God, they're like trolls." Rose saw Mace say next to the Doctor. Rose noticing the Doctor's eyebrows in a frown, eyes slightly dark. Rose smiled a small smile over at her husband as she took in his worried features as he tried to save the planet and to some extent herself and Donna

"Yeah, loving the diplomacy" Rose muttered to herself slightly causing Donna to laugh.

"So, tell me, General Staal, since when did you lot become cowards?" The Doctor said loudly to the Sontaran's as he moved from behind the console to the vacant chair in front of it. His feet automatically going to the surface of the desk

"How dare you!" Staal snapped "Doctor, you impugn my honour!"

"Yeah, I'm really glad you didn't say belittle cos then I'd have a field day" The Doctor joked, putting enfaces on certain words. He was shaking his head, his eyebrows raised as he spoke "But poison gas? That's the weapon of a coward and you know it. Staal, you could blast this planet out of the sky, and yet you're sitting up above watching it die. Where's the fight in that? Where's the honour?" The Doctor shouted again, his eyebrows moving into a frown, his head raised "Or, are you lot planning something else? Cos this isn't normal Sontaran warfare. What are you lot up to?"

"A general would be unwise to reveal his strategy to the opposing forces."

"Aaah, the war's not going so well, then?" The Doctor chimed happily, his legs swinging him on the chair, his torso leaning on the back of the chair, his face looking away " Losing, are we?"

"Such a suggestion is impossible." Staal snapped

"What war?" Mace interrupted

"The war between the Sontarans and the Rutans. It's been raging, far out in the stars for 50,000 years. 50,000 years of bloodshed, and for what?" The Doctor said quickly, not once taking his eyes from the Sontaran's as he spoke over to Mace and then back to Staal.

"For victory. Sontar-ha!" Staal shouted before punching his fist to the palm of his hand the rest of them following his lead

"Sontar-ha! Sontar-ha! Sontar-ha!"

"Give me a break." The Doctor muttered before he rolled his eyes. He pulled out the Sonic Screwdriver and changed the channel to the cartoon of Dexter's Laboratory. Rose smiled at his choice

"I always new he was a Dexter fan" Donna smiled

"I think he just likes to laugh at it, or it's because the American has a German accent" Rose joked which caused Donna to smile. Donna was currently sitting on the Captain's chair, her legs crossed while Rose was leaning on the console

"So these sontaruns" Donna asked

"Sontarans" Rose corrected

"Yeah them? They enjoy warfare?" Donna said, pointing over to Rose as she corrected him

You could call it that. There a clone race, bred only for war, to win the war with the Rutans. Thousands of people have died, the two planets nearly consumed, all goodness and any hope of the war to end soon is lost" But Rose swiftly stopped what she was doing and moved her head back to the screen when she realised the Doctor had soniked the screen back to the Sontaran's and he reappeared on the screen.

"Finished?" He asked, his face sceptical

"You will not be so quick to ridicule when you'll see our prize. Behold!" Staal stated as she gestured towards the TARDIS which was behind him "We are the first Sontarans in history to capture a TARDIS."

"Well. As prizes go, that's...noble" The Doctor said gently, his eyebrows raised, eyes wide. Rose looked over at Donna as she motioned her forward as she looked at him via the screen, taking in his leant form as they spoke." As they say in Latin,Donnanobis pacem."

"That's me. I'm here!" Donna said quickly

"Did you never wonder about its design? It's phone box. It contains a phone. A telephonic device for communication. Sort of symbolic. Like if only we could communicate. You and I." The Doctor said staring at the screen, his fingers moving into a phone sort of shape.

"All you have communicated is your distress, Doctor".

"Oh my god." Donna muttered to herself as she grasped hold of Rose's phone picking up on the thought while Rose was working on the console, springing into action

"Oh I am way ahead off you" Rose said with a smile as she continued to fly around the console as if she knew it like the back of her hand. -

"Big mistake though. Showing it to me coz I've got remote control" The Doctor voiced as he showed the Sonic Screwdriver. Rose simply rolled her eyes, knowing exactly that he was bluffing.

"Cease transmission!" Staal snapped and the transmission was completely cut off.

"Doctor, what number are you on?" Donna yelled at the vacant screen "You haven't even got a number!"

"Oh yes he does" Rose smiled as she looked over at Donna around the central column. "If I use the wavelength the Sontaran's are they wont be able to pick up the transmission, we can bounce that off their sensors and beam it back to earth to get a communication back to the Doctor. You need to use this number for it to work" Rose smiled over at her, finishing her job before typing in the number and walking back to the screen

"You're a genius you know that?" Donna smiled over at her to find she was connected to

"Oh here we go!" Rose said smiling

"I knew you would get it" the Doctor chimed from his seat causing Rose to return his brilliant smile "you both ok?" The Doctor asked as he got to his feet and leaned forward slightly

"Yeah, were fine" Rose smiled

"Just a bit shaken" Donna voiced just as both of them stumbled, Donna reaching out for Rose who caught her and steadied her to her feet.

"What's going on?" The Doctor asked concerned, his eyebrows moving into a frown

"Feels like were being moved, most likely beyond a transmission field, we might have to keep in contact via my mobile or our link" Rose said as she clung onto the railings as she tried to look at the screen properly. Mace looked over at Rose with one of his eyebrows raised when she said the last part of the sentence. There was very little written on the Doctor but they did know about a strong emotional bond that can exist between two Gallifreyans. This woman really must mean a lot to the Doctor if they shared this sort of connection.

"Rose do you know why they need the TARDIS?" The Doctor enquired, she just shook her head and shrugged her shoulders

"If I'm honest, I think they are using it as a trophy, knowing what this means to their race. But they want to keep you earth bound, causing you to die with the rest of the human race"

"Well isn't that just Wizard" He complained. Rose just smiled at his gently

"But knowing Sontaran's they will probably cut all links with the planet, deadlocking the teleportation pads." Rose voiced. The Doctor nodded "We can bring the systems back online so we can teleport back to earth, bringing the TARDIS with us"

"Good plan, ok, you know what to do?" The Doctor nodded

"Of course, you made me study their ships remember" Rose smiled, being sarcastic

"Oh you never cease to amaze me" The Doctor beamed

"Must be the reason you married me"

"Right ok, hop to it and ill contact you soon"

"Alright, talk to you soon" Rose finished before cutting the link and getting herself and Donna ready as they waited for the Doctor's orders.

The Doctor was striding around the room, his eyes dark as the task of trying to help and save his wife was weighing down on his hearts. He walked over to Martha who was standing in front of the canisters of Gas, a clipboard in her hands before he plucked it from her hand.

"There's carbon monoxide, hydrocarbons, nitrogen oxides but 10% unidentified. Some sort of artificial heavy element we can't trace. You ever seen anything like it?" Martha asked up at him, her eyes falling back to the canister before the Doctor leant forward to get a closer look, his glasses present on his features his eyebrows in a frown

"Must be something the Sontarans invented. This isn't just poison, they need this gas for something else. What could that be?" The Doctor said quickly and quietly before standing up again before snapping his head back to the direction of Price's voice

"Launch grid online and active."

"Positions ladies and gentlemen, Defcon One initiatives in progress." Mace informed as he moved to the centre of the room, the Doctor simply stared at him, marching over to him angrily, his eyebrows still in a frown his mouth in a harsh line

"What? I told you not to launch!" The Doctor bellowed

"The gas is at 60% density, 80% and people start dying, Doctor. We've got no choice." Mace said calmly looking over at the Doctor

"My wife is aboard that ship" The Doctor managed to say through gritted teeth

"I'm sorry Doctor but we've got no other option" Colonel Mace said again, this time trying to be polite and considerate.

"Launching in 60, 59, 58, 57, 56… Worldwide nuclear grid now co-ordinating. 54, 53... " Price counted down, the Doctor simply stepped back, his hands going through his hair as he watched the count down commencing. He thought weather the TARDIS could protect them, if Rose could be clever, figure out that whatever was keeping the TARDIS there was broken and she could escape. Because once again the Doctor was facing a life time without the TARDIS and without Rose.

"You're making a mistake, Colonel! For once, I hope the Sontarans are ahead of you." The Doctor snapped

"North America, online. United Kingdom, online. France, online. India, online. Pakistan, online. China, online. North Korea, online. All systems locked and co-ordinated. Launching in 10, 9, 8, 7, 6, 5..."

"God save us."

"...4, 3, 2, 1..."

"0." The screen snapped off, leaving the UNIT soldiers confused, frustrated and leaving them a blank screen full of static.

"What is it? What happened? Did we launch? Well, did we?" Mace demanded, watching as the people around him was trying to get readings and information

"Negative, sir. The launch codes have been wiped, sir. It must be the Sontarans." Price said with a frown while the Doctor looked over at Martha suspiciously, taking cautious steps towards her

"Can we override it?" Mace asked, looking down at his soldiers

"Trying it now, sir." Price voiced as she continued to work on the console.

"Missiles wouldn't even dent that ship, so why are the Sontarans so keen to stop you?" The Doctor said over to them before he leant down slightly and looked down at Martha "Any ideas?"

"How should I know?" Martha confessed, shaking her head slightly, having a frown pressed on her face.

"Enemy within! At arms! Greyhound 40 declaring absolute emergency. Sontarans within factory grounds, east corridor grid six." The Doctor heard the voice of Ross over the radio the Doctor walking over to the console his lips pursed open slightly as he listened to what was happening around him

"Absolute emergency, declaring Code Red. All troops, Code Red!" Mace ordered over the radio

"Get them out of there!" The Doctor snapped quickly, his face looking right at Mace who ignored him

"All troops, open fire!" Mace demanded over the radio, the sound of guns clicking sounded over the radoi

"The guns aren't working. Inform all troops, standard weapons do not work." Ross shouted again, just for his answer to be his whole company screaming "Tell the Doctor it's that Cordolaine signal. He's the only one who can stop them." But he was cut short and static filled the line over the radio. The Doctor simply staring into space as he realised what this meant, his mouth dry, his eyes wide with sorrow.

"Greyhound 40, report. Over. Greyhound 40, report. Greyhound 40, report!"

"He wasn't Greyhound 40, his name was Ross." The Doctor said to him darkly, his voice harsh and raspy, his eyes staring into the distance before he flicked them towards Mace "Now listen to me, and GET THEM OUT OF THERE!" He yelled

"Trap One to all stations. Retreat. Order imperative, immediate retreat!"

"They've taken the factory." Mace informed which caused the Doctor to frown, rub his chin as he walked around the console to the screens

"Why? They don't need it. Why attack now? What are they up to? Times like this, I could do with the Brigadier. No offence." He ranted slighted

"None taken. Sir Alistair's a fine man, if not the best. Unfortunately he's stranded in Peru." Mace said, shaking off the Doctors insult

"Launch grid back online." Price stated just for the screens to turned back on showing the map of the world and then suddenly going blank again

"They're inside the system, sir. It's coming from within UNIT itself." Price said over her shoulder towards her commanding officer

"Trace it. Find out where it's coming from, and quickly. Gas levels?"

"66% in major population areas. And rising."

"Why are they defending the factory only after we were inside?" Mace asked, his question directed purely to the Doctor. The pair of them having walked into his office, sheets of maps and paper littering the desk in front of them, the Doctor having his glasses pressed to his nose

"Because they wanted UNIT here. You gave them something they needed. Something now hidden inside the factory. Something precious." The Doctor said gently, the revelation springing to his mind, his head moving upwards slightly, his glasses still on his nose, Mace was looking up at him

"Then we've got to recover it. This Cordolaine signal thing, how does it work?" Mace asked

"The bullets. It causes expansion of the copper shell." The Doctor answered, standing to full height and pulling off his glasses before replacing them in his pocket

"Excellent. I'm on it." Mace chimed as he got up and left, causing the Doctor to sigh a heavy sigh of frustration

"For the billionth time, you can't fight Sontarans!" He yelled before he walked out too towards the nearest officer, making sure that Martha couldn't hear him

"Phone. Have you got a phone? I need your mobile, quickly, hurry up!" He whispered just to be handed a mobile and walked back towards Mace's office. The Doctor closed the door behind him, looking out towards the others as he pressed the phone to his ear, hoping Donna would pick up

Donna jumped when she heard the phone that was ringing in her hand. Rose was underneath the console slightly, she was doing something to the TARDIS while they waited for the Doctor's orders, but at the sound of the phone she snapped her head in the direction of Donna and removed herself and stood, watching as Donna got to her feet and pressed the phone to her ear.

"What's happened, where are you?" Donna said over the phone, her voice worried and panicked.

"Still on Earth. But don't worry, I've got my secret weapon." The Doctor whispered over the phone, hoping he wouldn't be heard

"What's that?" Donna asked

"You." The Doctor simply stated, moving around the office as he spoke to her.

"Oh." Donna muttered, her face and shoulder's falling as she realised what this meant. Rose simply looked over at her, her hands being whipped by a cloth which was nearby "Somehow that's not making me happy. Can't you just zap us down to Earth with that remote thing?"

"Donna he doesn't have a remote control" Rose said over to her gently, Donna looked over at her and rolled her eyes, the Doctor smiling when he heard his Wife's voice. Comforting their friend even in the darkest of situations.

"Yeah, I haven't got a remote, though I really should. Can you pass me over to Rose?" The Doctor said and asked her. Donna was nodding her head a small smile on her lips as she realised the Doctor must have been struggling not having Rose next to him

"Yeah, she's just here" Donna chimed before holding out the phone to Rose. Rose smiled over at her before striding around the console and taking the phone from her

"Hey" Rose said gently before readjusting her grip on the phone

"You ok?" The Doctor asked concerned, he looked over his shoulder before he moved further into the corner, hoping this conversation would be private. He knew he wasn't showing it but the Doctor was struggling not to worry about Rose and Donna, they were in a further more dangerous situation he was in and he was worried something could happen and he would lose them. The Doctor just had to keep reminding himself that they could look after themselves that they were strong and he had no need to worry.

"Yeah, were fine you?" Rose breathed, knowing that the Doctor was worried, she could feel it via their link, even if she was 100 million miles away or what ever it was

"Well, you were right about Martha" The Doctor said with a smile, trying to change the topic, to try and make him feel better

"I was?" Rose said into the phone, a frown forming on her face as she tried to understand the Doctor's statement. Knowing that something was wrong with Martha.

"And again you're doubting yourself" The Doctor sung, his head lifted in the air as he leant against the wall, a small smile on his face as he spoke to Rose

"Right, sorry" Rose said clicking her mouth slightly and nodding in the process

"You were right about the teleport system as well, it's deadlocked, your going to have to reopen the link so we can use it" The Doctor said, going back to business finally giving them something to do

"Ok, keep the line open and ill see what we can do" Rose said to him before placing the phone in her pocket and looking over at Donna who was looking at her with a frown, Rose just smiled over at her gently before going over to her "Okay Donna were going to have to go outside"

"But there's Sonterruns out there." Donna panicked, her eyes wide with distress

"Sontarans, but they'll all be on battle stations right now. They don't walk around having coffee. Ill be right next to you so you don't have to worry" Rose ranted, taking her hand slightly and giving it a squeeze of comfort.

"But what if they find us?" Donna sighed slightly defeated

"We're just going to have to risk it" Rose said to her gently before staring right into her eyes "but there's nothing else we can do. The whole planet is choking, Donna." She implored. Donna was looking down at the ground before she looked up at Rose and nodded slightly

"What d'you need me to do?" She said as the pair of them walked towards the TARDIS door

"The Sontarans are inside the factory which means they've got a teleport link with the ship, but they'll have deadlocked it. We need to reopen the link." Rose explained to her, her hands moving in gestures as she explained to Donna what their task was and how they were going to do it. Her features were soft and kind as she watched Donna nodding as she took it all in

"But, I can't even mend a fuse." Donna defended

"Donna! Stop talking about yourself like that. You can do this. I promise." Rose praised, encouraging her, Rose knowing that the woman in front of her could do amazing and wonderful things. Donna nodded before the pair of them snuck a glance out of the door to see a Sontaran a few feet away from them, his back to them. They both silently closed the door behind them before looking t each other and preparing themselves for what was about to happen.
