The rain pelted down as Lexi and Jack ran down the dead street cybermen not fair behind.

Jacks coat flew through the wind curling round his soaked body, his clothing clung to him and his shoes squeaked as the water seeped through.

A shot fired towards Jack and Lexi shoved him to the side and the shot hit the space he once stood in.

Lexi let out a laugh as Jack glared and pulled out her gun from her boot and shot three cybermen down with a smirk.

They were about to turn to run again when a man came out of a nearby side street almost running straight into the cybermen.

"FOOL!" Lexi screamed and before Jack could say a word she ran towards the man as a cyberman grabbed the man by the coat. She kicked her leg high and the head of the cyberman holding the stranger flew off. With a shove Lexi set him forward towards Jack.

Whilst grabbing the foolish man by the coat and dragging him they were running again.

"Jacky, next left opposite the church, 20 seconds" Lexi called as she sprinted off into the distance.

Jack grabbed the man's coat now and smiled. "Good to see you again Doctor"

By the time they reached the church Lexi was already waiting in a Jeep. The Doctor and Jack jumped in and Lexi floored it driving at high speeds until they reached Torchwood.

When they arrived the building was dark. Jack walked ahead and turned the power on.

"ARE YOU INSANE!"? Lexi screamed as she stripped of her coat and threw it onto the lobby sofa.

The Doctors eye's grew in shock at the fiery woman. Instead of an answer he took in the woman.

Her hair was as black as night and her skin as white as paper. Her cheeks had the slightest pink to them and her bright neon green eyes shinned in the light. She was very curvy that was very apparent through her soaked clinging clothes.

Jack cleared his throat to snap the doctor back to earth. He blushed slightly as he looked at the woman's glaring eyes as she watched him look her over.

"Hi, I'm the Doctor" He said holding his hand out to her.

Lexi did not shake his hand and just took him in. "This is the Time Lord?"

Jack laughed and nodded. "Handsome isn't he?"

Lexi ignored his comment. "I'm surprised you couldn't feel me and I couldn't feel you."

"Huh?" the Doctor asked VERY confused.

"I'm Lexi, I'm a Time Lady" she said smiling.

"I don't understand" The doctor said shocked. "you can't be, I'm the last of my kind"

Lexi smiled sitting on the arm of the sofa looking between Jack and The Doctor. "Apparently not"

"What is your name?" The Doctor asked still not sure what to think.

"Lexi, I don't remember my real name, I have amnesia, I lost my memory" she said almost sad.

"Jack picked up readings thinking it was you but it was me, when he found me I couldn't remember who I was and where I was from. After a few test's we discovered what I was. Since then I've worked for torchwood."

The Doctor looked at her in disbelief.

Lexi sighed and got up and took his hand and placed it on her chest. In gallifreyan she spoke "I have two heartbeats"

The Doctor pulled away and looked away from Lexi.

"Lexi it is bad enough you talk to yourself in gallifreyan do I now have to put up with two talking to each other in it?" Jack said with a sigh, but his smirk on his face betrayed him.

"Jack why didn't you tell me?" The Doctor asked with a dark look in his eye.

Jack now looked angry "I tried to but you have been avoiding me since Rose"

The Doctor flinched at the mention of her name and turned back to look at Lexi before quickly turning back around embarrassed.

Jack let out a laugh as he saw Lexi stood there in her wet trousers an now just a bra.

"Don't you want to go to another room?" The doctor asked a little red in the face.

Lexi laughed as she put on a dry top and proceeded to pull of her trousers. "I'm not ashamed of my body, and jack has never minded..."

The Doctor interrupted before she could finish "Jack wouldn't complain, he likes anything with a pulse"

Lexi scowled at The Doctor and Turned him around now fully clothed again."Is there something wrong with my body? Because I could be wrong, but you didn't seem to mind it earlier"

Jack smirked "Lexi stop making the poor man feel uncomfortable, we all saw him looking and to be honest it's properly been a while for him..."

"Ok stop!" The Doctor said feeling uncomfortable.

"If you don't mind Lexi I would like to do a few tests, maybe I can get a ID for you from my tardis.

In all honesty Lexi didn't want to. When she met Jack they took blood and tested this and that and was made to feel like some kind of animal. She had hoped it would be over with now. But here she was going through it again, with a man who was carless in battle and refuses to believe she is what she is.

Shouldn't he be happy? She thought to herself...No longer alone.

Lexi sighed and looked to Jack then The Doctor. "Yes it is fine, but first we have a cyberman infection to deal with"

"yes, of course" The Doctor said smiling.

Jack walked over to the computer and pulled up the file on the cyberman case.

Lexi and The doctor joined him, each one side.

The Doctor pulled on his glasses and Lexi stifled a laugh whilst he glared at her.

"The situation had started small, we had a few disappearances, we hadn't even had any sightings but in the last 4 hours we have had 12 deaths and sightings all over cardiff." Jack said showing clips from the news and photo's from the crime scenes.

Lexi now turned to the doctor "We evacuated the area's of contact not long before we saw you to reduce the risk of more deaths, luckily it was in our jurisdiction so we could do this as swiftly and as sensibly as possible"

"But why are they killing the victims? they usually put them through transformation.." The doctor asked now pacing.

Lexi pulled out a small silver device from her pocket, it had a flashing blue light on it and she tossed it to the doctor.

The doctor pulled out his sonic screwdriver and scanned it checking the readings.

"If I'm correct someone is controlling the cybermen, and me and Jacky found the headquarters." Lexi said smirking.

The doctor looked at Lexi raising an eyebrow whilst Jack walked over and put an arm around her and kissed her head.

"Isn't she fantastic!?" Jack said beaming.

The doctor looked at Lexi not blinking.

"He's not used to competition is he?" Lexi asked smiling to jack.

Jack shook his head and they both looked to the doctor who was now walking towards the doors.

"Doctor don't you dare!" Jack called to him.

The doctor stopped in the doorway but did not turn around. "It's not safe for you both, I'm going on alone"

Lexi scoffed and the doctor turned. "Look pretty boy! I have been working with Jack and the team for 4 years now. Not one case has been closed and it's not going to start now. This is our case and I'm sorry but if you want to come that is fine but you are not telling me or Jacky what to do. I get you have been alone and I get you thought you were the last of your kind. It's scary I know, imagine how I feel? I have no idea who I am. So you ain't leaving my sight!"

Lexi put a gun in her boot and grabbed a big knife and put it through her belt on her now dry clothes before pulling on her coat again. With that she walked out of the door not even looking at the doctor and Jack followed smiling at the shocked doctor.

Once Lexi parked the Jeep The three of them ran to a crate and hid behind it looking at the dark abandoned warehouse for activity.

Jack typed something into his vortex manipulator and looked to Lexi "I'm going to open the doors for you and space boy over there. It looks clear."

"1. it's not safe, and 2. you shouldn't have that" The doctor said pointing at the vortex manipulator.

Jack ignored the doctor and turned to Lexi. He placed a hand on Lexi's cheek and looked into her eyes. "Be safe" Lexi smiled and then he was gone.

"Ok pretty boy, you heard the boss, let's go" Lexi said pulling out her gun.

Lexi and the doctor walked silently and slowly across the dark quiet court yard.

"I don't like guns, and I don't do killing" The doctor said in disapproval.

"The way I see it doctor is not to kill. If I can I won't but if it's a choice between them and the people I love...I will do anything to keep them safe." Lexi said strength in her voice.

"You don't know me, why would you need to protect me, and trust me Lexi I don't need protection" The doctor said confidentially.

"I have read all about you doctor, the man with all the power. I also know you will do anything for your companions. And I will not let you die...your my future." Lexi said sadness in her voice.

They reached the door and it was slightly open. Lexi stuck her gun through first and checked and it was clear. The doctor waltzed in and scanned the air with his sonic screwdriver and Lexi looked down the quiet halls.

"Jacky?" Lexi called her face filled with worry.

The doctor started walking down one of the halls and Lexi followed covering them from behind.

"Where's Jacky?" Lexi asked the doctor as he muttered to himself.

"I told him it wasn't safe" The doctor said "It was too quiet for a warehouse storing cybermen"

There was a scratching noise and the doctor pulled Lexi into the dip in the wall.

The doctor held his hand over her mouth as the cyberman passed . When his footsteps faded he released her and she sighed.

"I'm letting my judgement get clouded" Se said looking to the floor.

The Doctor took her hand. "That's what makes us different from others...like cybermen...we feel, we love..."

Lexi smiled and he released her hand.

"Let's find Jack" The doctor said leading the way

The doctor and Lexi continued down the corridor until they came across a hall, it was lit and they could hear the sound of cybermen walking.

The doctor walked through the open door and they stood on a balcony above a hall filled with cybermen and a woman standing above Jack's motionless body.

"Jacky!" Lexi whispered as she tried to run to the stairs but the doctor pulled her back down.

"hold on...that's Cassandra...The judoon took her last summer, she was convicted for killing the queen of Dido. She used to be a torchwood employee. She had stolen the vortex manipulator and was fired when she returned. Next thing we know the receive word from the Judoon she had been reported and to hand her over. We tried to help her but it was too late." Lexi said.

"It seems she has escaped, and she brought some friends." The doctor said eyeing the hall full cybermen. "We need to inform the judoon of her location. They aren't exactly to the book...and if we don't I don't doubt they will hold earth responsible.

The doctor and Lexi were so caught up in there plan they didn't see the cyberman who was behind them. The cyberman sent a wave of electricity through their bodies.

Lexi and the doctor fell to the floor shaking as the pain flowed through them. The cyberman finally stopped and Lexi looked at the doctor her vision going blurry. The doctor was unconscious. Lexi fought the blackness as hard as she could but her body had other ideas. Before unconsciousness took over she reached for the doctors hand and took it in her own and then everything went black

Jack was the first to wake. His eyes felt heavy and his body sore. When his vision came into focus he tried to move his hand to his pounding head but couldn't. He was perched up against a wall and his hands were bound in chains.

Jack thrashed against the bounds a few times before giving up with a huff.

Suddenly the once dark room lit up and Jack flinched from the bright light. When his eyes adjusted he was shocked by what he saw, there were rows of cybermen but in front of him sat Cassandra. She smiled down to him in her chair and just stared.

The doctor now stirred and caught Jack's attention next to him sat an unconscious Lexi.

Her body was limp and the only thing holding her head from the floor was the chains. At the far end sat the doctor who was still coming round.

"Ah, it seem's our mystery guest has decided to join us" Cassandra said quite amused.

The doctor now looked over to Jack and smiled. "Jack! Glad your still with us"

Jack rolled his eyes and looked back at Lexi. The doctor did the same and both boys frowned in worry.

"You better have not hurt her Cassandra!" Jack spat, hate dripping from every word.

Cassandra just laughed. "some things never change Jack, Lexi is still your main concern"

Jack frowned at her comment. "All of my employees are my concern" he said.

"Please!" Cassandra almost screamed. "If you cared half as much for the rest of us as you did for her then I wouldn't have been taken!"

The doctor now joined in. "Cassandra what you did is through no fault of your own, you used a device illegally, travelling to a planet of tree people. I met the queen once and she was most charming, wouldn't hurt a living thing. Whether you killing her was an accident or not it happened.

The judoon hadn't sentenced you to death so therefore you weren't found guilty. So what Is it you want?"

Cassandra now stood and walked over to Lexi and grabbed her by the hair pulling her face up so she could look at her.

Jack struggled against his chains as he watched her look at the Time lady's face.

"I want torchwood to pay for what they have done to me. They fired me and left me alone for those...THINGS to take me away. I was scared and they abandoned me." Cassandra said sadness in her eyes.

"Why do you need the cybermen?" the doctor asked watching carefully as Cassandra pushed the hair back from Lexi's face.

Cassandra let Lexi's body drop again and stood. "I can't take down torchwood on my own, and I don't want to be sent back to that awful prison again. I have control of those robots and I am going to send them to torchwood to gain control."

"While my friends there take control of torchwood I have something special planned for lover boy and his time princess. I wasn't expecting you though" Cassandra said now looking at the doctor.

"Who are you?" she asked bending down to his eye level.

The doctor smiled an evil smile and leaned closer to her. "The man who is going to stop you!"

Cassandra stood smiling. "I can see why Jack likes you."

With that Cassandra turned to the cybermen. "My friends, let the chase begin!"

The cybermen all turned and one by one they walked out of the room.

Cassandra turned back to the doctor "I learnt a lot about technology while I was away, amazing how a small chip wedged into the circuits and a master plan embedded into software can go a long way."

Lexi began to stir and they all looked to her "ouchy" she said pouting and tying to reach her head but the chains held her arms down.

Lexi immediately sat up eyes wide before noticing Cassandra.

"I always knew you were unstable" Lexi sad with a smirk.

Cassandra slapped her across the face causing Lexi's to be thrown in Jacks direction.

Lexi just looked back at Cassandra smiling.

"oops" she said whilst Cassandra shook in anger.

"Lexi behave, she has the upper hand here" The doctor said in astonishment.

Lexi turned to the doctor giving him the puppy eyes before saying "Don't spoil my fun"

Jack laughed and looked to the fuming Cassandra.

"You think this is funny Jack?" Cassandra spat at him.

Jack contained his laughter and smiled at Cassandra.

Cassandra pulled walked over to the table and picked up a needle. Making the three prisoners alert.

"Jack you made sure I was completely alone, so now i'm going to show you how that feels. My cyberman are out taking over torchwood but I have also sent one to all of your closest colleagues and friends houses."

Jack sat there in complete shock, his mouth opened and closed but he didn't know what to say.

"But this here?" Cassandra said pointing to the needle. "This is pure spectrox, you can get it all over the universe...and in its pure form it is lethal...even for time lords"

As realisation hit the two men they both looked at Lexi who sat with her face emotionless.

"Don't you dare touch her!" Jack screamed as Cassandra neared Lexi.

"Please don't do this!" The doctor pleaded. "I know they hurt you Cassandra but it doesn't have to be like this. Start your new life. I have a ship, I could take you anywhere you wanted, give you a fresh start...please"

Cassandra kicked Lexi in the face knocking her to the floor.

Lexi let out a moan as she spat out blood from her mouth.

Cassandra unchained Lexi and pulled her by the hair to kneel in front Jack.

"I want you to look the woman you love in the eyes as I kill her!" Cassandra.

"Your a coward Cassandra. I'm sorry we couldn't help you, but this? This is low even for you. Cold blood murder." Lexi said her voice thick with disappointment.

Jack looked into Lexi's eyes as the doctor squirmed in his chains.

"I'm sorry Lexi" Jack whispered

"Don't be"Lexi said smiling. "Been nice knowing you handsome."

Lexi turned to the doctor. "I'm sorry pretty boy, over before it's started. Remember me"

and with that Cassandra Jabbed the needle into Lexi's neck and she screamed as the liquid entered her blood stream.

Lexi fell to the floor in a scream as the liquid burned inside her body as her hearts pumped it around.

Lexi gathered all her strength and kicked Cassandra knocking her off the stage. She then proceeded to crawl across the floor to the table where Jack's vortex manipulator was laying and grabbed it. She pressed a few buttons and threw it to jack.

Jack wiggled around and grabbed the device but hesitated when he looked at Lexi and the doctor.

"Go Jack, help the others." Lily said through clenched teeth before her body thrashed in pain.

Jack nodded and pressed the button and disappeared. Lexi began to grow weak and looked to the doctor.

"Hey, hang in there" the doctor said smiling.

Lexi smiled "I'll try, I just feel sorry for you having to face Cassandra when she wakes up. I'm just glad I got to meet you before this"

The doctor looked to the floor in guilt. He was so wrapped up in hate and Rose that he didn't even think there could be anyone else out there.

The doctor looked up to say he was sorry but he was too late, when he looked to Lexi she was motionless on the floor.

A tear rolled down the doctors cheek as he looked at the time lady...he failed her and now he was truly alone.
