Gaia met Jack when she was only 2 days old. She met the Doctor not long after that, but it isn't until the Doctor pulls her out of the burnt remains that is her home planet, Starnet, that everything changed. Covers 10/11, not always in order with Torchwood series 1 and 2 added to the mix. Warning future femslash... Doctor/OC/River

11. So It Came To Pass

Disclaimer: I do not own Doctor Who or Torchwood, both belong to the BBC and their respected writers. But I do own Gaia! :b

A/N: Sorry for the wait, I try to get slightly ahead on chapters before I update them. And I aim to write 5,000 a chapter so they take awhile. Anyway, thanks for the reviews they mean a lot. I'm glad people are liking the story.

Gaia was blinded by a golden light as she stood beside the Master. It numbed her pain, so she welcomed it with open arms and it seemed to hug her back. When the gold light finally receded she was no longer being held by the arm watching her world burn, she was in someone's arms, someone who wore scratchy tweed and a bow tie. "Sh, it's alright. You're safe now." The 11th Doctor said softly to Gaia, holding her close. Gaia leant into the Doctor and wept, happy to be out of that horror.

*10 Minutes Earlier*

The Doctor worked frantically around the console, pulling levers and flicking switches. "What are you doing?" River asked him, but he was too busy to give an intelligent reply.
"I know where she was." He said to himself more than River. His head was now under the console as he stripped and knotted 2 wires together.
"Where who was?" River asked, her patients wearing thin.
"Gaia." The Doctor mumbled a wire in his mouth as he connected another 2.
"But she just left." The Doctor pulled himself out from under the console and ran over to the monitor. "Doctor, how could it be Gaia, she just left!" River now demanded standing next to the Doctor. The Doctor turned to face her.
"It's a younger her. Gaia's known me and you for quite a while, she knew you, in theory, before you even knew her. Anyway, she disappeared once, well escaped really and I never found out where she went." The Doctor explained.
"Where did she go?" River asked, her anger subsided and worry in her voice. The Doctor smiled at her.
"With us" and a golden light filled the console room, emanating for one point. Although blinded, the Doctor made his way to the centre of the light and hugged the forming golden figure. The sound of sobs quickly filled the room and the image of Gaia formed.

*Present*

Gaia had stopped crying now and was eerily silent. River mouthed a question to the Doctor who answered with a shrug. Looking down at the now still form on his shoulder, the Doctor kissed Gaia's forehead. "Are you okay?" The Doctor asked and River face palmed. But to both their surprise Gaia didn't respond. River tried again.
"Sweetie..." River said, hoping to get some reaction of Gaia. But her head remained on the Doctor's shoulder and her mouth shut. River raised her eyebrow at the Doctor.
"She's not asleep, her breathings too shallow." The Doctor assessed and slowly lifted Gaia's head off of his shoulder.

Gaia was very much awake, but so lost inside herself that she may as well have been asleep. Her eyes were open, yet they were glazed and distant. The Doctor gulped at her expression. "Doctor, what's wrong with her?" River asked her voice full of worry as one of the most important people in her life stood in front of her with an expression of the walking dead.
"I don't know." The Doctor replied, his voice hoarse. He brushed a piece of hair out of Gaia's face and looked at her spaced out eyes. He planted a kiss on her forehead before scooping her up bridal style. "Medical room." The Doctor urged and carried Gaia down the stairs, River following close behind.

The Doctor carried Gaia into the large clinical room the Tardis had installed and laid her down onto the hospital bed. The Doctor then pulled a large device over the top of Gaia and set it to scan. The results were instant and they didn't look good. "She's killing herself." The Doctor said gravely, his eyes flittering over the scan results on the monitor.
"What? What's wrong with her?" River said instantly looking over the Doctor's shoulder and reading Gaia's results. "Oh..."

"She's severed the bond with Earth and her body can't cope." The Doctor summarised to River, who now had a tear rolling down her cheek.
"But she can't, you said she was younger, she just..." River sobbed. The Doctor pulled her into a hug. This River was young, still so naive to the true cruelty that the universe could create for him and to those closets to him.
"Time can be re-written River. If Gaia dies here then our time with the older her will be rewritten; the older version will never have existed." The Doctor explained solemnly. River looked up at the Doctor.
"We have to do something." River stated, all previous emotions forgotten and a look of determination on her face. The Doctor smiled.
"Oh you just watch me." He said and untangled his arms from River and got instantly to work.

The Doctor pulled several large contraptions from cupboards and wired Gaia up to near on all of them. He had 3 ECG's set up, each measuring one of Gaia's hearts. He had put her on an IV and had placed 2 patches on her stomach that released hormones to stimulate her liver and kidneys for a short period of time. He had also placed an oxygen mask over her mouth and nose and whilst doing all of this Gaia's eyes still remained wide open.

"What are you going to do?" River asked, helping the Doctor tape the inserted IV onto Gaia's arm.
"We, River, what are we going to do. I need as much help as possible for this to work. We're going to enter Gaia's mind and convince her to reform the bond with Earth." The Doctor explained.
"Will that work?"
"Honestly, I have no idea. But I'm a bit thin on the ground for ideas here. There's probably a way of saving her without the reformation of the bond, but... I don't know how. A Planet Keeper's anatomy was a well kept secret held by every member of the race, even I only know very little of it." The Doctor admitted. "So we're doing this and I need you to trust me." River smiled softly at him.
"Always." She replied.

The Doctor looked on one of the monitors set up next to Gaia's bed. "Alright, the Artemin has reached her heart. Meaning we can get started." The Doctor explained and held River's hand.
"What does Artemin do?" River asked, she had never heard of the drug before.
"It allows us to do..." The Doctor grabbed Gaia's hand and both he and River were plunged into darkness. "...this."

River could still feel the Doctor's hand in hers, but she was completely blind by the darkness she now found herself in. "Where are we?" River asked.
"We're in Gaia's mind." The Doctor explained and started to walk forward pulling River behind him.
"So that's what the Artemin does, allows us to get into her mind?"
"Not quite. It channels her mental synapse into her skin. More or less anyone who touches her at this moment in time would be plunged straight into her mind." The Doctor explained to River.
"Okay, so where is Gaia then?" River questioned.
"I don't know. She's probably hiding out of fear. We're going to have to find her."
"But how are we going to do that, its pitch black in here?" As soon as the words had left River's lips, lights suddenly filled wherever they were.
"I think she heard you." The Doctor said slightly smug to River. River rolled her eyes. "Come along Song, let start looking." He continued and pulled River forward in the white expanse space they now found themselves in.

As the couple walked forward, their white surroundings slowly changed. A path formed beneath their feet and blue grass began to grow down the path edges. In the distance a house came into view and the sound of a sobbing child could be heard from a near-by tree. The Doctor slowly approached the tree with River at his side.

"Hello?" The Doctor called softly and a small head poked itself from the other side of the tree.
"Hello..." The little girl sobbed. "Who...are...y...you?" She asked, now standing up and facing the Doctor. She was only a little taller than his knee.
"I'm the Doctor, what's your name?" The Doctor replied crouching down to the girl's level. The girl didn't answer him, but instead looked past him at River.
"Who are you?" She asked.
"I'm River."
"Oh..." The little girl said and started to fiddle with her hair. "You better get through the door so Gaia can find you." The girl continued.
"What door?" The Doctor asked and the little girl pointed behind them.
"That one." Both River and the Doctor turned to see a plain wooden door standing in the middle of the path, their seemed to be nothing on the other side of it, but both time travellers were experienced enough not to judge on appearances.

"Okay..." The Doctor said turning back to the little girl, only to find that she had gone. He then stood up straight and brushed his trousers down.
"Doctor who was she?" River asked, now taking a hold of the Doctor's hand again.
"I think it was Gaia's daughter. Luna." The Doctor answered, now approaching the door.
"Oh..." was River's only response.

Gaia, older Gaia, had told her about her only daughter, Luna. River herself had been in tears when told. She knew from first experience what it was like to be in a life and death situation at such a young age, River was just fortunate enough to survive her ordeal.

The Doctor turned the rusted handle on the door and pushed it ajar. "What's through there?" River asked, not able to see what lay beyond the door. The Doctor was currently closer to the door but could make out little of what lay beyond.
"I don't know." The Doctor admitted. He then turned back to River and offered his had to her. "But let's have a look shall we?" He continued. River laid her hand in his and squeezed his hand tight. "Come along Song." The Doctor said, worryingly giddy and walked through the door, River at his heels.

What was on the other side came as a surprise to both time travellers. They were in the TARDIS console room, but it wasn't the current console room. They were in the coral console room; 9 and 10's console room. "Doctor, are we in another TARDIS?" River asked as she begins to inspect the coral beams.
"No, this is what the console room looked like before." The Doctor explained and ran up to the console. He inspected it for every detail. "This is a hell of a replica though; every button is in the right place, every lever..." He ducked under the console and pulled out the mallet. "Every hammer. It's an achievement I'll give you that." The Doctor admitted and turned around to face River.
"Okay, if we're in a TARDIS, or at least a replica of yours, where are we?" River asked. The Doctor raised his finger and opened his mouth to reply, but then realised he didn't know the answer.
"I don't know." He conceded and pulled round the monitor to have a look. River walked up to his side and read the Gallifraen symbols over his shoulder.

"WHO IN RASSILON ARE YOU?" A voice bellowed from behind them. Both River and the Doctor slowly turned to see the 10th Doctor standing there, trench coat and all.
"Err..." The 11th Doctor uttered speechless at the sight of his past self. He couldn't help but ponder why he thought the sideburns were a good idea.
"2 of you, the mind wanders." River joked, causing the 11th Doctor to blush. 10 also, quite randomly, started to laugh.
"You should have seen your faces." He laughed and both River and 11 looked at him confused. "You'll be wanting to go to Gaia's room, that's the next door." 10 explained, but 11 and River stood their frozen with confusion. "Come on chop, chop. Geronimo or whatever you say these days. Gaia hasn't got long and your wasting time talking to me." 10 said and pushed River and 11 down the corridor.

The push seemed to be exactly what 11 needed and as he entered the corridor he broke into a run, dragging River along behind him. "Okay now I'm confused." River stated as she ran next to the 11th Doctor down the Tardis corridors.
"Well that makes for 2 of us." The Doctor admitted.
"Was that actually you?"
"I don't know."
"If you don't know, then why are we listening to him?"
"...because we don't have much else to go on at the moment."
"Fair point." River conceded and came to a halt next to the Doctor as they stopped outside Gaia's door. The Doctor looked up at River.
"Ready?" He asked. River nodded in response and the Doctor opened Gaia's bedroom door.

The scene that lay before them was a vast difference to one they had left. They now found themselves in the storage hanger of a rather large star ship. There were several large crates within the room, all coated in a layer of dust and grim. The air smelt stagnant and stale; it was an obvious deduction that no one had been in here for ages.

"Okay, now where are we?" The Doctor asked himself, licking his finger and putting it up in the air. River rolled her eyes at the Doctor's actions and looked behind her at the way that they'd come.
"Well wherever we are sweetie, there's no going back." River told the Doctor. The door the couple had entered the hanger through now no longer existed. All that lay behind the pair now was a rather grimy wall.
"Hmm..." The Doctor mused and took a step forward and began sniffing the crates.
"I wouldn't." River advised and the Doctor promptly sneezed from inhaling the dust. "Told you so." River chuckled. The Doctor wiped his nose on his sleeve and continued investigating.

River also started looking around, but found nothing of interest, until her ears pricked up at a very familiar sound. "Doctor, there's gun fire on approach." She warned and quickly stood by the Doctor's side.
"I know, I heard. We're just going to stand our ground okay. This is just an illusion, it's not real." The Doctor explained and River nodded her head in agreement. They linked hands and stood facing the direction the sound of gun fire was coming from. The sound slowly got louder and the beginning of running footsteps could be heard; both River and the Doctor couldn't help but hold their breath in anticipation.

With a flourish a concealed door, bang in front of the duo, flew open and one of the most unlikeliest people ran in. Captain Jack Harkness. "What are you both doing just standing there? RUN!" Jack shouted, grabbing a hold of the Doctor's arms and pulling him, as well as River, across the room.
"Jack? What are you doing here?" The Doctor yelled as he ran next to Jack, River on his other side.
"I'm not Jack, but I'll explain in a minute when we're not running for our lives." The Not Jack replied.

The trio continued running towards what River and the Doctor presumed as another wall, but at the last minute the wall opened to reveal itself as a door to another room, almost identical to the last. This pattern of running at `walls` repeated itself 3 more times until, in the 5th room, Jack swerved right at the centre and ducked behind a crate, dragging a surprised Doctor and River with him. The thundering footsteps of whatever was chasing them passed the trio and they all took a sigh in relief.

"Well that was close." The Not Jack said relieved.
"What was that thing?" River asked, breathless from all the running.
"I'm not quite sure; I think it's like an anti-body of sort, resetting the brain. It's already trashed its way through the other levels; it was only a matter of time before it got here." The Not Jack explained, his head leaning back against one of the crates.
"Wait levels, that means... this is Gaia's mental security system." The Doctor realised with raised eyebrows. The Not Jack nodded.
"Yes and the fact you've been able to figure that out means Gaia is incredibly weak. You've got to help her. Please." The Not Jack pleaded.
"We're trying, but how do we get to her?" River retorted to the Not Jack. The Not Jack let a smile grace his lips.
"She's behind you." He said and disappeared in a puff of black smoke.

Both River and the Doctor turned around. In front of them was Gaia, but she was the Gaia they had left on the hospital bed, a dying woman. "Hi." Gaia said softly to the both of them, she looked tired and could only muster the smallest of smiles.
"Hello." The Doctor replied softly and slowly approached Gaia.
"I should probably ask what you're both doing here, but it's kind of obvious." Gaia admitted.
"Yeah..." The Doctor agreed.
"But I had too, they were all dying and I couldn't do anything." Gaia began, tears now rolling down her cheeks. "He butchered them and I could only watch it happen. What kind of planet-keeper am I if I can't even look after my own planet?" Gaia sobbed and fell into the Doctor's outstretched arms. The Doctor stroked Gaia's hair.
"I know, but everything's better now. The Earth's safe and back to normal." The Doctor said attempting to comfort Gaia.
"How? It was in ruin, the Master had won." Gaia retorted her voice lost of all hope.
"Martha did it. She saved the world. And if you want proof, just look at River. You know as well as I do what year she left Earth." The Doctor assured.

Gaia looked up at the Doctor questioningly, her face still glazed with tear tracks. She then turned to face River. Unwinding her arms from around the Doctor, Gaia approached the other woman and proceeded in prodding her in the arm.
"Ow?" River stated, proving to Gaia that she was really there. Gaia instantly wrapped her arms around the other woman, much to River's shock.
"You're real and Martha did it and..." Gaia blabbered, not stopping for breath.
"Breath sweetie." River chuckled and wrapped her arms around Gaia. Gaia took a deep breath and laughed.

Around the trio, the beginning of many soft murmuring could be heard and dozens of little white lights began to appear. River and the Doctor were both entranced at the sight, yet to Gaia it was nothing new. "Thank you." She muttered to the both of them and gave them each a kiss on the cheek. Within a flash she was gone, as was the murmuring and lights.
"Doctor, where did she go?" River asked, concerned that they were back at square one.
"No where." The Doctor replied casually. "I think we're..."

Before the duo knew it they were back in the medical room, Gaia now sleeping peacefully on the hospital bed and them sitting at her side. "...waking up." The Doctor finished. He quickly got to his feet and rescanned Gaia.

"We did it." River squealed happily, reading the test results over the Doctor's shoulder. The Doctor sighed in relief.
"Yeah, we did." He admitted and fell back into the chair behind him in relief.
"Does you head hurt?" River asked, rather out of blue as she swayed a little and sat back down.
"A bit." The Doctor admitted. "It's probably the Artemin. A caffeine boost should handle that."
"Well that settles it then." River announced. The Doctor looked at her fearing the worst. "I'm going to have to stick the kettle on." She declared with a grin and the Doctor laughed at her and at his mind, it was forever thinking the worst.

Over the next few hours the Doctor remained at Gaia's bedside, whilst River was constantly in and out of the room, providing herself and the Doctor with a constant stream of tea. The couple talked a little, usually about River's time at university, although the Doctor would, on occasion, talk about one of his adventures. They both were particularly careful though; although Gaia was asleep they had no idea if there was a possibility that she could be listening, hence they didn't mention any adventures with her.

The Doctor also got round to explaining to River about the Master and `The Year that Never Was`, he described to her how Gaia had disappeared on the first day of the Master's ruling and how Gaia had been basically kept prisoner by the man for 18 months beforehand. Although River kept telling him otherwise, he also told her how it was all his fault and how he took any punishment from the Master almost happily for penance of what he put Gaia through.

A little after that Gaia showed signs of waking up.

Cracking open her eyelid, Gaia caught the blur image of brown with a spot of red. The Doctor. "Hi." She managed to croak.
"Hello." The Doctor replied cupping her face with his hand.
"I feel like I've been out on one of Jack's stag dos." Gaia joked, causing a chuckle out the Doctor and River.
"I can imagine" The Doctor replied. Gaia chuckled and attempted to sit up. "Ah, ah, ah." The Doctor said. "Bed rest and general non-moving for you, Doctor's orders." Gaia rolled her eyes, muttering something under her breath. "I've always wanted to say that." The Doctor admitted happily, turning back to River. River rolled her eyes.

A few days later Gaia was back on her feet and back to full health; she had made a full and quite remarkable recovery. She had now managed to get the Doctor on his own and she had a few questions to ask him. "Doctor I need to ask you something, well two something's and there important so don't give me some ramblings. Okay!" Gaia stated, not giving the Doctor to say otherwise. He just nodded and let her talk. "Firstly, on the Byzantium, you left to my right yet reappeared on my left. And then you kissed me. Care to explain?" She asked, hands on hips. The Doctor ran his fingers through his hair and sighed.
"As much as it kills me to say it... spoilers." He muttered and Gaia groaned in frustration.
"I hate whoever taught you and River that damned word." Gaia retorted and the Doctor out rightly laughed. "What?" Gaia asked, confused at the Doctor's amusement.
"Nothing." The Doctor replied, his laughter dying away. "What was your second question?" He asked.
"Well it wasn't so much as a question, more that I'm going to state a fact and you're not allowed to disagree or argue. Okay?" Gaia said and the Doctor agreed reluctantly. "It wasn't your fault." She said and walked away.

Gaia entered the console room, where she found River sitting at the bottom of the stairs. She walked down and sat beside her. "You alright River?" Gaia asked. "You've been awfully quiet." River brushed her hair out of her face. Gaia couldn't help but notice she looked very nervous a stark difference to the confident River she had met on the Byzantium.
"It's just... don't take this the wrong way, but its weird having a younger you here." River admitted quietly. Gaia chuckled.
"No worries, I get it. I guess it's kind of looking at a photo of someone before you knew them, they look like them but their not `your` them." River nodded in response. "If it's any consolation, it's kind of the same with you. I've only met you once before now and you were older then." River chuckled.
"We could never have a normal life use three, could we." River stated it was a fact not a question.
"Nah, where's the fun in that?" Gaia joked and both women laughed.

"What are you two laughing about?" The Doctor asked as he came walking in from the other corridor. This just caused Gaia and River to burst out laughing again. The Doctor pouted. "Oh come on sweetie, it wasn't about you." River assured the Doctor.
"Yeah, we were just having a girly chat. You know about..." Gaia didn't get to finish her sentence as the Doctor interrupted her.
"Alright, alright I get it no need to mentally scar me." The Doctor said putting his hands up in defeat. Gaia laughed at the gesture.

"Anyway, where are we going?" Gaia asked.
"We are going no where at the minute. You on the other hand have to return to younger me, Martha and Jack." The Doctor said, handing Gaia a vortex manipulator.
"Oh..." Gaia said, taking the strap and placing it on her wrist. "I have to go now?" She asked and the Doctor nodded solemnly. "Well thanks for everything I guess." Gaia muttered, trying to prolong her departure. She then had an idea. "First though." She said and turned to face River. She then kissed her on the lips, the taste of bubblegum and cherries filling her mouth once again. River stood there, slightly shocked as Gaia kissed her and remained in that shocked position when Gaia broke the kiss. Gaia laughed at River's expression. "Returning the gesture." Gaia joked.
"No kiss for me then?" The Doctor asked half-heartedly. Gaia turned to face the Doctor and chuckled.
"You'll get yours in a minute." She answered and disappeared in the usual crackle of the Vortex manipulator.

Seconds after Gaia's departure the doors of the Tardis swung open, scaring the hell out of the Doctor and River. At its door stood an older Gaia who marched in and straight up to the Doctor. She then proceeded in kissing him senseless. "Told you so." She gasped in between kisses, causing River to laugh and the Doctor to smile as they kissed.

Younger Gaia meanwhile, back in 2007, landed, rather unceremoniously, on the pavement on the Plass, much to the shock of 3 near-by people. "Ow." Gaia stated, standing up and brushing herself down, still not noticing the 3 shocked people staring at her. When she finally did look up, she couldn't help but feel a little self conscious. "Err... hi." She said with a little wave to the 3 shocked people, who happened to be Jack, Martha and the 10th Doctor.

"Gaia?" The Doctor said in disbelief.
"The one and..." Gaia didn't get to finish her sentence as the Doctor had ran over and hugged her so tight she couldn't finish.
"You're okay, you're fine." The Doctor said reassuringly.
"Aren't I always?" Gaia joked. "Although I may not be if you don't loosen you grip a little." The Doctor let got of her a blushed.
"Sorry." He muttered.

Martha had now walked over to the pair and prodded Gaia in the shoulder.
"Ow." Gaia responded much like River had not too long ago in the future.
"It's really you." Martha said shocked and gave Gaia a hug, much to Gaia's shock.
"Yep really me. Blue hair and all." Martha released Gaia with a smile.

Gaia then turned to Jack. He was still frozen in shock. Gaia pulled a joke. "Did he catch himself in a reflection again?" Gaia asked jokingly. "I swear it took me almost an hour to pull him away last time. He kept trying to seduce himself." Gaia joked, causing both Martha and the Doctor to laugh. Jack pulled a smile. He stretched his arms out and wrapped them around Gaia, bundling her in a hug.
"I'm just happy you're okay." Jack muttered. He towered over the Gaia and hence only got a muffled response from her.
"Almost sounds like you missed me." Gaia joked when Jack had finally released her. There was an awkward laughter out of the other 3.

"So what are you doing in Cardiff?" Gaia asked.
"Dropping me off." Jack answered and the Doctor turned to face him.
"I really don't mind though. Come with me." The Doctor insisted. Jack looked over the Plass and at Gaia.
"I had plenty of time to think during, well, anyway... and I kept thinking about that team of mine. Like you said Doctor, responsibility." The Doctor nodded and turned to Gaia.
"What about you?" He asked. "I can't deny I have millions of questions concerning your whereabouts, but it's your choice." Gaia ran her fingers through her hair, contemplating her decision.
"As much as I would love too Doctor, I should stay with Jack. And as to where I was, you'll figure it out eventually, you always do." Gaia replied and stood next to Jack.
"Defending the Earth can't argue with that." The Doctor conceded.

The Doctor then went to give Jack a hand shake but pulled his sleeve back at the last minute, revealing his Vortex manipulator. "Hey I need that!" Jack defended, but the Doctor wasn't having any of it and pulled his sonic screwdriver out of his pocket.
"I can't have you walking around with a time-travelling teleport. You could go anywhere, twice. The second time to apologise." The Doctor argued and disabled Jack's manipulator.
"What about hers?" Jack retorted pointing to Gaia.
"What about mine?" Gaia argued back, making the pair truly sound like arguing siblings.
"Aren't you going to disable hers?" Jack asked the Doctor, his tone whiney and childish.
"No." The Doctor replied sternly, like a parent would to arguing children. "She'd just re-enable it again if I did." The Doctor added and Jack pouted.

Jack sighed. "Sorry, brings out the worst in me. What about me, by the way, can you fix that? Will I ever be able to die?" Jack asked the Doctor seriously. The Doctor put his hands up.
"Nothing I can do. You're an impossible thing Jack." The Doctor replied and Gaia laughed.
"Been called that before." Jack began, elbowing Gaia to stop her from laughing. "I keep wondering though, what about ageing? Cause if I can't die but I keep getting older. The odd grey hair, you know? What happens if I live for a million years?" Jack asked hands on hips. The Doctor shook his head.
"I really don't know."
"Okay vanity. Sorry. Can't help it. Used to be a poster boy when I was a kid back on the Boeshane Peninsula. Tiny little place. I was the first one ever to be signed up for the Time Agency. They were so proud. The Face of Boe they called me." Jack chuckled at the memory. He gave both the shocked Martha and Doctor a salute. "I'll be seeing you." He said and turned and walked away.

Martha and the Doctor looked at each other shocked, before the latter turned to face Gaia. "I know." She said with a smile. "I better be heading off, God knows what trouble he's already got himself into." Gaia said with a little wave and began to walk away. She then doubled back on herself and walked towards the Doctor. "Last thing though..." She said and like River before, she snogged the Doctor senseless.

This was her first time kissing the 10th Doctor and he tasted different to the 11th. He tasted more refined, rather than the sweet explosive flavours off the 11th Doctor; 10 tasted like cinnamon and apple with a hint of whiskey. It was the taste of experience and age and it fit rather well with the 10th Doctor's personality.

The Doctor stood there dazed when Gaia broke the kiss and Martha stood there even more shocked than before. "Returning the gesture." Gaia chuckled and ran across the Plass to catch up with Jack.

"`Kiss, Kiss`." Martha said.
"`Bang, Bang`." The Doctor muttered and they both watched the 2 retreating figures with amusement.

"Oi, wait up." Gaia called running towards the retreating figure of Jack. Jack laughed and turned to face Gaia.
"Come on; let's see what the kids have been up to after we left 'em home alone." Jack joked and put his arm around Gaia's shoulder.
"I hope that was a metaphor." Gaia stated with a look of disgust on her face. Jack burst out laughing.
"Well..." Jack began. Gaia promptly whacked him on the arm, before she began laughing herself. The best friend, practically sibling, duo walked away into the city, heading back to the day (& night) job.
