A/N: Hello lovely readers! Oh it's good to be back! I wasn't planning for this to be my next story but the plot bunnies would not leave me alone, so here we are :) Well as you have probably figured out this is my re-telling of Human Nature only it has Jack (plus a surprise guest!) in it as well. Instead of the the events of Utopia happening when Jack shows up, the events of Human Nature/Family of Blood happen. You should all be aware that while I have borrowed many many lines from Utopia (because let's be honest, it's brilliant!) I will for sure be putting my own spin on the lines from Human Nature/Family of Blood. I don't want to just use the original lines but have other characters say them (not that there is anything wrong with that!). I would really really love some reviews for this! Alright... extremely long A/N done!

"Here we are! Cardiff," the Doctor exclaimed as he landed the TARDIS.

"Cardiff?" Martha shot the Doctor a disgusted look. "We can go anywhere and you brought me to Cardiff?"

"Ah, but, the thing about Cardiff is it's built on a rift in time and space. It's like California and the San Andreas Fault. The rift bleeds energy. Every now and then I need to open up the engines, soak up the energy, and use it as fuel."

"So it's a pit stop?"

"Exactly. Should only take twenty seconds. The rift's been active," replied the Doctor with a hint of interest in his eyes.

"Wait a minute, they had an earthquake in Cardiff, a couple of years ago. Was that you?" Martha asked, already figuring the answer was "yes." She was just beginning to truly understand how involved the Doctor has been with major events throughout history.

"A little trouble with the Slitheen. Long time ago. Life times. I was a different man back then," the Doctor answered while avoiding eye contact with his inquisitive companion. But Martha knew what that look on his face meant. Knew who he was thinking about. Out of nowhere everything felt off to the Doctor. Something felt... wrong. He glanced at the monitor and saw a figure running towards the TARDIS and realized what he had been feeling. It was defiantly time to go. "All powered up!" he said as he pulled the lever down and gave a smile. Leaving just in the nic of time. The TARDIS began to dematerialise, but, suddenly the console began to shudder and spark, sending the Doctor and Martha flying backwards.

"Whoa! What was that?" Martha asked, seeing the frightened look on the Doctor's face. He seemed just as confused as she was. She gave a scream as the TARDIS began jerking even harder, causing a shower of sparks to reign down on her.

"We're accelerating! Into the future! No, no, no! Stop this now!" The Doctor began twisting various knobs and pulling at different levers. Eventually he pulled his trusty mallet out and began banging on the control panel. The TARDIS landed with a sudden thud, leaving The Doctor and his companion flat on their backs.

"What happened? What's wrong with the TARDIS?!" Martha had never seen the ship act like that and now it was darker in the control room than it had ever been for her before.

"She's fine. Something spooked her, but she'll be okay. Just needs some time to recuperate," the Doctor answered in a hushed tone.

This made Martha feel slightly better. If the Doctor wasn't too worried then she shouldn't be either. "So where are we then?"

"No idea."

"Say that again! Not often you don't know something," Martha exclaimed, giving the Doctor a cheeky grin.

"What do you say Martha Jones, care to see what lies beyond those doors?"

"You bet!" She took a step outside but gave a sudden gasp at the sight of a man laying face down, next to the TARDIS. "Oh my god! Hold on, I got my medical kit inside..." Martha rushed past the Doctor, who just stared at the collapsed figure, without showing any surprise.

"Hello again. Oh, I'm sorry."

"Here we go! Get out of the way," said Martha as she pushed past the Doctor and began checking the man's pulse. "Where are we? This looks like a different planet but this coat looks more like World War Two."

"I think he came with us."

"How do you mean? From Earth?"

"Must've been clinging to the outside of the TARDIS. All the way through the Vortex. Weelll, that's very him."

This seemed to surprise Martha, who was still crouched down by the man the Doctor seemed to know. "What?! Do you know him?"

"Friend of mine. Used to travel with me back in the old days," he answered with nonchalance.

"But he's... I'm sorry there's no heartbeat. There's nothing. He's dead." Martha found the Doctor's lack of a reaction to her diagnosis troubling, but before she could even dwell on it, the supposedly dead man in question gasped back to life and grabbed hold of her, causing her to scream with freight. Her shock didn't last long though, as her medical training kicked in, and she tried to calm the man. "It's alright. Breathe deep. I've got you."

The now alive man turned on his full attention to the woman holding him. "Captain Jack Harkness, and who are you?"

"Martha Jones."

"Nice to meet you, Martha Jones." Jack flashed her his winning smile when he suddenly heard a new voice with a familiar tone.

"Oh don't start!"

"I was only saying hello!"

"I don't mind," Martha told the Doctor, as she began to blush while helping Jack to his feet. This Captain was quite the charmer, however as he stood before the Doctor, Martha could feel the tension rolling off him in waves. She was beginning to wonder just what had happened to these two friends.

"Doctor," Jack said stiffly.

The Doctor responded, "Captain."

"Good to see you."

"And you. Same as ever... although... have you had work done?"

"You can talk!" Jack said with surprise.

The Doctor was momentarily confused but then realised what he meant. "Oh yes the face! Regeneration. How did you know this was me?"

"The police box kind of gives it away." The Doctor gave a nod at that as Jack continued, "I've been following you for a long time. You abandoned me."

"Did I? Busy life. Moving on."

The was no regret in his tone yet, Jack could sense the sadness, and was afraid for the answer to his next question. "Just got to ask, the battle at Canary Wharf, I saw the list of the dead... It said Rose Tyler..."

The Doctor gave a sudden grin. "Oh no! Sorry! She's alive!"

Relied flooded through the Captain. "You're kidding!?"

"Parallel World. Safe and sound. And Mickey! And her mother!"

"Oh yes!" For the moment Jack seemed to forget his anger with the Doctor and ran to embrace the Time Lord.

Martha looked away. Here she thought perhaps this new guy would give her some of the male attention she had been lacking from the Doctor only to find he was just as fond of the mysterious Rose as the Doctor was. "Good old Rose," she muttered.

The trio began to walk around to try and figure out where they were since the Doctor, after checking on his beloved ship, announced the TARDIS needed a bit more time before they could leave. The Doctor remained quiet for the beginning of their walk letting Martha be the one to question Jack. The Doctor was feeling very troubled. The wrongness of Jack was getting to be a lot and on top of that whatever strange planet they were on didn't feel right. It seemed to be deserted, yet he could still feel a presence all around him.

Meanwhile Jack was explaining to Martha what happened the last time he saw the Doctor. "So there I was, stranded in the year 200,100, ankle deep in Dalek dust, and he goes off without me. But I had this!" he said as he pointed to his watch. "I used to be a Time Agent. It's called a Vortex Manipulator. He's not the only one who can time travel." Jack pointed to the Doctor.

"Oh excuse me, that is not time travel! It's like I've got a sports car and you've got a space hopper."

"Oh, boys and their toys!" Martha exclaimed. She was a little surprised a the Doctor's outburst. It made him seem very human.

"Alright so I bounced," Jack gave in. "I thought 21st century, best place to find the Doctor. Except I got it a little wrong. I arrived in 1869, this thing burnt out, so it was useless."

"Told you," said the Doctor with a smirk.

"I had to live through the entire 20th century waiting for a version of you that would coincide with me."

Now this truly shocked Martha. There was no way this young guy has lived that long. "But that makes you more than 100 years old..."

"And looking good don'tcha think?" Jack asked her with a grin before turning his attention back to the Doctor. "So I went to the time rift based myself there, cause I knew you'd come back to refuel, until finally I get a signal on this," He gave a point to the bag on his back, "detecting you and here we are!"

"But the thing is, how come you left him behind, Doctor?" Martha, who was suddenly angry for this Captain she had just met, questioned.

"I was busy," was the Doctor's answer.

Martha couldn't help but feel hurt over his response. When would the Doctor abandon her? Would he even leave her at home? "Is that what happens though? Seriously? Do you just get bored of us one day and disappear?"

"Not if you're blonde!" Jack injected with an old joke he and Rose used to have, not realising the hurt it would cause the Doctor.

"Oh, she was blonde?! What a surprise!" Martha was beyond frustrated.

"You two! Honestly, we are on a planet we have never been to before, it is dark, and suspiciously deserted and you're busy blogging!" The Doctor was trying to sound angry but both Jack and Martha could detect the hurt in his voice.

Out of nowhere voices began to surround them exclaiming, "Time Lord.. Time Lord... It's a Time Lord..." Jack and Martha both turned around, towards the direction they had been coming from trying to find the source of the voices when suddenly a laser beam shot past them. The Doctor pushed them both forward.

"Run!"

The three travelers continued to run while ducking the various beams that were being shot at them. Jack went to grab his gun when the Doctor stopped him. "No, Jack, don't! Don't turn back! Just keep running."

Jack couldn't help but give a sideways glance to the Doctor. "Oh I've missed this!" he shouted, which, of course, caused Martha to laugh. Neither realised just how serious the situation had become.

When they finally reached the TARDIS, they all fell in quickly and shut the doors. The Doctor immediately began the dematerialization process and then turned his attention to Martha. He asked, "Did they see you?"

"What?" she responded.

"Did they see you? Did they see your face?"

"I.. uh... I don't think so..."

"Martha, you can't just think you have to know! Did they see you!?" he said as he grabbed her shoulders.

Martha continued to look flustered by the Time Lord's outburst so Jack came to her aid with, "No, they didn't see her. There's no way they saw either of us, we both had our backs turned when they began firing. Now what is going on, Doctor?"

A chime from the console interrupted what the Doctor was originally going to tell Jack. Instead he told them, "They're following us. They'll follow us wherever we go."

"How is that possible? We're in a time machine!" Martha cried.

"Vortex Manipulator," the Doctor answered while glancing at Jack.

"Don't look at me!" Jack defended. "Mine's still on my wrist and I told you it doesn't work anymore."

"Of course it's not your's. Their's must be stolen. But that mean then can follow us any time, any place. They'll never stop... unless..."

"Unless what, Doctor?"

"I'll have to do it," the Doctor said, mainly to himself since neither companion knew what he was talking about. "Blimey." He began to tug on his hair.

"Do what? Doctor, we need some answers over here," Jack stated as he began to grow impatient.

Instead of answering him, the Doctor turned his attention to his female companion, "Martha, do you trust me? This is important. I need to know that you, without a doubt, trust me because this could all depend on you."

"I trust you," she answered while looking him straight in the eyes.

"Good," he replied as he pulled something round off the console. "You see this watch? The watch is everything. This watch is me."

"What do you mean, Doctor? What's happening?"

"I have to stop being a Time Lord. I'm going to become human."

Martha just stared in silence, while the Captain had the opposite reaction, "You're going to do WHAT?! Doc, you can't do that. I mean won't that hurt?"

"Oh yes. I imagine it will hurt quite a bit. But I have to admit, I've always been curious about this particular device," the Doctor answered as he stared at an object dangling from above. "Now listen, Jack, I'm not sure where or when the TARDIS is going to land to hide me out so I can't exactly take you home but I can fix you're 'space hopper' so you can bounce away as soon as we land."

"No way. I don't know exactly what's going on but I'm sticking with you guys. Doc, listen, let me help."

The Doctor stared at Jack. He still made him feel uncomfortable but he had to admit that it would be helpful to Martha to have someone else, who knew the situation, around. "Alright," he answered as he gave Jack a nod.

"Thank you. Now you have to tell us exactly what is happening because, honestly, I don't know about Martha, but, I am pretty damn confused about what is going on."

The Doctor looked at his two companions and then began to explain The Family of Blood and what they could do to him. After that, he told them his plan for becoming human by using the chameleon arch. Neither Jack nor Martha were pleased with the news that the Doctor would have no memory of them or himself as a Time Lord, but, the Doctor explained to them how this would be best. After answering their questions as best as he could he sent them off to the wardrobe room to pack some bags for their three month stay wherever the TARDIS decided.

A short while later, Jack walked back into the control room where the Doctor was just turning the monitor off. "I was just filming a little instructional video for you and Martha to watch after I change," the Doctor told him with a sideways glance. "Where is Martha?"

"Still packing. How long have you known?" Jack asked, knowing the Doctor knew what he was talking about.

"Ever since I ran away from you. How did you know I knew?"

"Could tell by looks you were giving me."

"When did you realize?" the Doctor asked, finally turning and facing his old friend.

"Earth. 1892. Got on a fight on Ellis Island. A man shot me through the heart, then I woke up. Thought it was kind of strange. Then it never stopped. Fell off a cliff, trampled by horses, World War One, World War Two, poison, starvation, stray javelin," he said while the Doctor winced. "In the end? I got the message. I'm the man who can never die. And all that time you knew?"

"That's why I left you behind. It's not easy even just looking at you, Jack, cause you're... wrong."

Jack tried not to look hurt, "Thanks."

"You are! I can't help it. I'm a Time Lord. It's instinct. It's in my guts. You're a fixed point in time and space. You're a fact. That's never meant to happen. Even the TARDIS reacted against you and tried to shake you off."

"So what you're saying is you're prejudiced?"

The Doctor couldn't help but give a small chuckle. "I never thought of it like that."

"Shame on you!" Jack replied with a chuckle of his own, which caused Martha, who was finally finished packing, to pause in the corridor outside the control room. She was still curious about the friendship between these two and decided to quietly listen in our their banter.

"Yeah," the Doctor replied to Jack. He couldn't deny that he did miss having the Captain around.

"The last thing I remember, back when I was mortal, I was facing three Daleks. Death by extermination and then I came back to life. What happened?" Jack finally asked, waiting for the answer he had been curious about for over 100 years for.

"Rose," the Doctor said matter of factly. Martha couldn't help but shake her head, still hiding in the hall. Who was this amazing girl who could apparently make a human man immortal and a Time Lord fall madly in love?

Jack took a deep breath. "I thought you'd sent her back home?"

"She came back. Opened the heart of the TARDIS and absorbed the Time Vortex."

"What does that mean exactly?" the Captain questioned, remembering their time in Cardiff when Margaret the Slitheen was turned into an egg by the TARDIS's heart.

"No one's ever meant to have that power. If a Time Lord did that he'd become a god. A vengeful god. But she was human. Everything she did was so human. She brought you back to life. But she couldn't control it. She brought you back forever. That's something, I suppose," the Doctor said with a shrug. "The final act of the Time War was life."

"Do you think she could change me back?"

The Doctor answered while avoiding eye contact, "I took the power out of her." He turned his eyes back to his friend and the anguish Jack saw there broke his heart. "She's gone, Jack. She's not just living on a parallel world. She's trapped there. The walls have closed."

"I'm sorry."

"Yeah," answered the Doctor who turned away again to try and school his features. Martha was holding back her own tears caused by the pain in his voice.

"I went back to her estate in the 90's. Just once or twice. Watched her growing up. Never said hello, timelines and all that," Jack told him sadly, realizing he was truly never going to see Rose again. It was like losing his little sister. Even when he saw her name on the list of the dead, he had the hope she was still with the Doctor. He took a deep breath as he stepped beside his friend. "Doctor about the 'not if you're blonde' comment I made. I didn't mean anything by it. It was a joke Rosie and I had about why you liked her more than me. I'm sorry."

The Doctor finally gave a real laugh at that. "It's fine, Jack. Now on to business."

Martha wiped her eyes and cleared her throat as she decided now was a good time to rejoin the men in the console room. "Done! All ready to be human, Doctor?"

"I suppose so," the Doctor told her as he pulled the contraption that would make him human onto his head, "Now, no matter how much pain I'm in, you two must leave this on me until it is finished. I'll be unconscious for a while but don't worry, I'll be fine. Just watch the video I left you and then get me out of here. Oh, and remember to take the watch and the psychic paper with you!" He took a deep breathe as he stared at his companions. "Well, see you in a few months. Allons-y."

The machine turned on causing the Doctor to let out an anguished cry.

The knock at the door brought John Smith out of his day dreams and into reality as his maid walked in the room bringing him his favorite tea.

"Everything alright, sir?" she asked, not recognising to look confusion on John's face.

"Oh yes. Just thinking about this strange dream I had last night. Wait a second, Martha, what are you doing here? I thought you had the day off and you were spending it in the village?"

"Oh I'll be leaving shortly, sir. Just thought I would bring your tea first. Is that alright?" She never knew how to read this human's moods.

"Of course!" he responded with a grin. "You take good care of me, Martha. I'm glad to have you around."

"Thank you, sir. Is there anything you need me to pick up for you in the village?"

"Oh, I'm quite alright, but thank you for asking. Now go on! Go enjoy your day off!"

"I will, sir," she said with a small curtsy, "Have a nice day yourself!" With a final glance at the fob watch on the shelf, Martha head out of the school she was currently employed at, and made her way down the road to the abandoned barn the TARDIS was parked in.

"Jack? Are you here yet?" Martha called out as she made her way into the control room of the somewhat dark TARDIS.

"I'm here, Martha!" Jack answered as he popped up from under the grating. "I was just looking for this!" he held up a rather old looking torch.

"What you need that for?"

"I'm gonna look for my old room! Wanna come?" he asked as he started to head out.

"Nah. This is my first day off in the week since we've been here and I am exhausted. Right now I just want to sit down and pretend it is not 1913 and that I am not a maid." Martha ended her statement by plopping herself down in the chair by the console.

"Have fun with that!" Jack gave a shout half way down the hall.

Martha closed her eyes, just starting to doze off, when she was jerked awake by the sound of the TARDIS door swinging open and a stranger's voice calling out, "DOCTOR!?"

"Who the hell are you?"
