AN: So, I thought about it and well it seems completely plausible to me that if the walls between worlds were falling, then another version of the Doctor could arrive. And if there are infinite universes, then there has to be one that includes Doctor/Martha. So while I won't bash Rose, Rose fans are warned: I'm no 10/Rose shipper, it actually disgusts me. It was just too, *waves hands in splat motion* too squashy. The universe obviously agreed with me. Lol [no really don't read and review mad that I don't like Rose. I'll only delete it...]

Warning: This is only a teaser right now. I may or may not continue this. If I do, it will be in this story. So feel free to place it in your alerts.

Disclaimer: I don't own Doctor Who. This is just a random bit of something, that I'll one day expanded. Maybe.

"Right, new plan." A tall, skinny man said to his companion. His companion, a female teen no older than fourteen looked amused at the idea.

"Run?" She replied. He grinned at her in a manic way. The man pulled her in a direction of their ship, a blue police call box. "Dad!" The two made it to their ship, evading angry blue aliens from the planet Xyon.

The man circled the console pulling a lever that allowed them to take off. "Let's not mention this to your mother."

The girl grinned, her father always said that. "It was supposed to be shopping dad. For a dress, for a school dance. I should have went with Aunt Tish."

The Doctor pouted at his daughter over the console. "Really, I would have thought this would've been a fun experience."

"You just wanted to make sure my dress isn't compromising and I still haven't got one." The girl leveled a glare on him that reminded him of his lovely wife. "Because someone decided to annoy a security guard."

The tall man in a pinstripe blue suit and red trainers, straightened his tie. "I wasn't annoying him. I was merely making an inquiry on why the surveillance system seemed to include the restroom stalls. How was I suppose to know that the public wasn't aware of it?"

"Dad, how did you even figure that out?" The teen with olive skin, dark hair in a spiky ponytail and brown eyes asked. She wore a blue button down shirt with a gray vest over it, jeans and gray trainers. Her hands were shoved in her jean pockets. The teen was definitely her mother's child.

"Well Miranda, let's not talk about that? I know another place we can go." This time the Doctor seemed even more excited. Miranda bit her lip, for some reason she was sure her father was about to drag her into even more trouble.

Miranda grabbed on to a nearby rail, "This is worst than usual." She commented as the TARDIS experienced turbulence. The Doctor looked worried for a second before he started pulling more levers and examining the screen. The TARDIS gave one big shake before holding still. Pulling herself to a more steady stance, she moved towards her father. "What happened?"

"We were pulled into a rift."

"A rift, like the one in Cardiff?"

"Well, no. Like the one in Norway." The Doctor stared at the doors of his TARDIS wearily. "We can't stay, we shouldn't even be here." Miranda knew her father was serious. She also knew he was curious and she would be lying if she said that she wasn't as well. "The rift looks like it'll be open for another few hours. Right then..." The Doctor clapped his hands and looked at his daughter.

She looked at him, her expression was obvious. "A bit of exploring?"

"As long as we don't take too long." He replied before taking off for the door.

"Oi wait for me!" Miranda shouted a gleeful expression on her face. "Woah." Her expression became serious as she looked at the damage around her. Her father's face held a frown. She walked over to him and clutched his hand. He gave her a reassuring squeeze before looking around.

"EXTERMINATE!"

"Why am I not surprised?" The Doctor muttered to himself as a dalek arrived on the scene destroying a car that had been driving by. "Go back to the TARDIS, now."

"Dad?" Miranda asked, she didn't want to leave him.

"Now Miranda." The Doctor wasn't sure how he'd get rid of the dalek nearby. The sonic had no affect on it and Ace wasn't around to blow them up. [He was thankful for that and yet he missed the girl.] His daughter released his hand, but didn't move. The lucky part for either of them was a blast destroying the dalek.

A familiar American face appeared. "Hey Doc!" The Doctor looked at him with shock. The last time he had seen Captain Jack Harkness, the young man had died in the Game Station. Why was he alive now? How had he survived?

"You're alive?" The Time Lord asked in bewilderment. Jack frowned at him before his eyes landed on Miranda.

"Funny. You know very well I'm alive." The American retorted. "And you've got a younger companion."

The Doctor didn't get to explain, before a familiar grinding sound was heard. Miranda glanced behind her, their TARDIS hadn't moved. "Is that-?" She asked. Jack frowned at them.

"Sounds like the TARDIS." Jack concluded.

The Doctor nodded, "Too right. What's happening here? And how did the rift open this wide?"

"The Dalek's Crucible would be your best place for answers." Jack replied. He looked over at them, but didn't get to ask anything as another familiar voice cried out "DOCTOR."

Miranda glanced at her father and noticed he had gone pale. "Rose Tyler?" The Doctor ran around the corner, Jack and Miranda following.

Jack glanced at her, "How old are you?"

"Fourteen, give or take a few years. Dad likes to make it difficult to keep track of." Miranda replied, only to stop short as she caught sight of her father- no her father of this world falling. Jack froze as well, but only to aim his gun and shot the offending dalek. Miranda ran forward only to be held back by her father. "Dad?"

"We need to get him to his TARDIS."

"Will some kind of paradox be created considering there's two of you in one TARDIS?" Jack asked as he ran to the side of the other Doctor.

The Doctor scratched his head. "Not from this world, the TARDIS should be fine."

"Doctor?" Rose asked as she looked up from her position beside him.

"Rose Tyler." The Doctor replied, his eyes swept over her and the body of his counter part. "Its always a pleasure to meet myself. Jack grab his other side." The Leader of Torchwood Three handed his gun to Rose. The blond had tears streaming down her face that she hastily wiped away, as she slung the gun over her shoulder. Rose followed Jack and the Doctor, only glancing at the other girl once. A redheaded woman looked over the group coming towards the TARDIS. Her hands covered her mouth as she stared in horror at the dying Doctor. "Right everyone inside, he needs to regenerate and I'd like an explanation on some things."

The Doctor laid his self down and smacked himself awake. "Really, the Earth's being destroyed by Daleks and you get hit by one? How thick are you?"

"Where did you come from?" The other Doctor asked.

The Doctor grinned, "Pulled in by the TARDIS. You should get started regenerating. Its like spoiling myself. Think we'll be ginger this time?"

"What?" Rose asked as she kneeled next to the Doctor. She reached and grabbed the dying Doctor's hand. "He...you promised." Jack held on to the distraught redhead. Miranda was staring at the blond as if she'd never seen blonds before. Jack reached out and placed a hand on the younger girl's shoulder. "You promised forever."

Jack glanced away from Rose and the Doctors, and caught the sight of the girl's eyebrows raising. It reminded him of...of the Doctor actually. "Rose, you need to step back." The Doctor placed a hand on the blond and nodded to himself.

"Forever? Funny concept with me." The Doctor told Rose as he watched the golden energy of regeneration surround his counterpart.

Miranda tugged on Rose's shirt attempting to get the blond's attention. "Were you telling him to not regenerate?" She wanted to make sure her assumption was right.

"Don't." Her father said flatly, before perking up. "Ooo...wonder what sort of face I'll have this time?"

"Why are there two of you?" The redhead woman asked.

As the light of regeneration died down, her Doctor's voice replied. "His TARDIS was pulled to our world. I'm assuming that was because of the Daleks." He surprised everyone by still wearing the same face. In fact, he had shot the regeneration energy into a jar containing his hand. "Same genetic material, just took enough energy to heal myself." He smiled charmingly at his companions.

"How did they manage to open a dimensional rift?" The Doctor asked himself. "Very clever. Where did you get the hand?"

"Lost it Christmas day in a sword fight." The other Doctor replied. "Nothing should have been able to penetrate the walls. Rose, you mentioned Bad Wolf?"

The blond nodded. "The stars in my world started going out and then the dimension cannon started working."

"I noticed a few planets were missing in my world as well." The Doctor stated. He frowned, "What do you mean dimension cannon?"

Rose looked at both Doctors and grinned. "I promised forever and so I needed to get back to my Doctor."

"Gag me." Miranda retorted. "We get pulled here because you built...had built a cannon meant to destroy the walls between parallel universes? How many worlds did you destroy before ending up in this one? Better yet, dad and I got ripped from our world to this one."

"Dad?" Rose repeated looking from the teen to the Doctor. Even the other Doctor, Jack and his redhead companion were looking at the teen in shock.

"Yes and I'm Miranda Jones. Apparently I don't exist here."

Jack recovered first. "Captain Jack Harkness." He smiled charmingly at her. Miranda blushed and glanced away.

"Honestly Jack, you never change." The Doctor replied sending him a warning look.

"Donna Noble." The redhead introduced herself before looking at Miranda closely. "Your mum wouldn't be a Doctor Martha Jones would it?" Donna had a grin on her own face. She had liked the younger woman and thought she was mad to leave the Doctor.

Miranda grinned, "She exists here? I thought something happened and that's why dad's got a blond stalker."

"Miranda Jones, what would your mother say?" The Doctor replied. "Honestly, you don't know any of these people and its not like we're in my TARDIS." He made a face at, "can't throw people out for trying to kill you. Your mother would have my head if something happened to you and I happen to like this face too."

Miranda shrugged, "I swear dad, you've got the worst luck in the world. Dalek invasion, while shopping for a dress." The girl hung her head. Donna patted Miranda's shoulder.

"Nothing will ever go right with him."

"Mother mentioned that."

"Did Martha warn you about going out with him?" Jack asked with a small smile.

Miranda sighed, "She mentioned I'd end up in a cell and saving some planet."

"Upside, you aren't in a cell." The Doctor reminded her as he examined the hand in the jar. "And Martha would know, did we tell you about our trip to Scotland?" He inquired as he turned around and straighten up, shoving his hands into his pocket.

Rose was still in shock. "The one where she was arrested for wearing her jeans?" The other Doctor asked recovering.

"Happened here as well?"

"She thought it was hilarious."

"She wanted a trip to a bar afterwards."

"Took mine to the library, she read up on medical history."

The Doctor patted himself on the shoulder. "Where is she?"

"With UNIT, when she left me I made sure they got her." The other Doctor replied. "So I got with Martha Jones in your world? We've even got a daughter." Something in his face showed longing as he glazed at Miranda. At least the Doctor figured that's what it was, he did know himself for the most part.

"Two." The Doctor replied. "Jennifer Jones. Incident on Messaline...happened here as well?"

The Doctor examined the face of his counterpart. "What happened to Jenny?" Miranda looked up at that point curious.

"Shot in her left heart. Martha was there. She died in my arms."

The Doctor frowned. "B-but that doesn't make sense." Whatever else he had to say was cut off as the TARDIS was apprehended by the Daleks. "Forgot about them. We'll continue this talk."

"What happened to me?" Rose finally asked. "You replaced me? Or...or did I not exist in that world?"

The Doctor held on to the railing near the corridor. "You existed there Rose. We even traveled together."

"You didn't love me?" The blond finally asked. Miranda looked ready to comment, but her father shot her a look.

"Rose, I love all my companions. Its just...I didn't love you in that way. In my previous body I cared for you a great deal. However, I couldn't keep you around. I realized that I was becoming the center of your very empty and unsatisfying life. It wasn't fair to Ricky and you needed to ground yourself. Don't get me wrong, Rose and I had great times, but Rose was more like a child to someone my age. Playing dress up, always wondering off and complaining when things don't go her way. Maybe you're different from my Rose, I don't know. But I do love Martha Jones."

The power in the TARDIS cut off. The doors were forced open and the Dalek leader reigned supreme. After forcing the TARDIS occupants to leave, before Miranda or Donna could leave the doors slammed shut. Both Doctors tried to get to the daleks to open the door. Jack winced, as he looked at his Doctor. He may not have known either female long, but he knew both were about to be devastated. Then the floor opened up and the TARDIS dropped.

Neither Doctor spoke, before the Doctor (from the other universe) rounded on the Daleks. "What did either of them do to you? Nothing! You want to see me in pain. Fine." The Doctor reached for his sonic, but was stopped when Jack decided to distract the Daleks.

"Let me go."

"No."

"That's twice." The Doctor replied.

"I know." His counterpart replied. His counterpart squeezed Rose's hand in reassurance. "Martha will kill you."

"I'd deserve it." Neither Doctor spoke as they found themselves trapped in cells with Rose between them.
