I wrote a story for cosmic-shine featuring the Ninth Doctor, Fitz Kreiner, Donna Noble, and Susan Foreman; with appearances from the First, Eighth, and Tenth Doctors, Sam Jones, and Barbara Wright. It's three pages for me, and I may even continue it (in which case Tegan may appear, as I've been introduced to her now). This was a great deal of fun to write, and I hope you enjoy it too!
Fitz Kreiner had his hands in his pockets and whistled as he walked along the street. The Doctor was shopping. With Sam.
And so, Fitz watched the windows and marveled at the future. It didn't look particularly future-like to him— none of the cars flew, and he couldn't see a single hologram or robot— but it certainly wasn't the 1960s.
Fitz turned a corner and saw the TARDIS. That was strange— this wasn't where they'd landed. They had, in fact, landed in a dumpster. Fitz turned around and saw the TARDIS.
Three TARDISes? The impending doom, paradoxes, shouting, running, and lack of proper explanations was already giving him a headache. Maybe if he walked away and ignored them, nothing would happen...
“You big outer space dunce!” shouted a woman's voice, “Running off, leaving me here. What's he even doing? Probably just doing his— four. Four TARDISes. What is so special that he's got to be here four times?”
“Feminine products?” Fitz offered, turning to see the woman. Red hair, brown leather coat. “I'm Fitz Kreiner.”
“Donna Noble. So you're with him too?” Donna put her hands on her hips and surveyed the pair of TARDISes. “That makes two of us, and four TARDISes.”
“So who's in the other ones?” Fitz stood beside her, folding and re-folding his arms.
“And what's going to try to kill us?” Donna added, looking from TARDIS to TARDIS. “Nice to meet you, by the way.”
A TARDIS door opened, and a small, dark-haired girl stepped out.
“Grandfather? Are you— you're not Grandfather.”
“Donna Noble and Fitz Kreiner,” said Donna, “We travel with the Doctor.”
“But— oh! You're from the future? Oh, I'm dreadfully sorry. He can't get you back home either?” The girl looked at the other TARDIS in mild alarm and locked the door of her own. “I'm Susan.”
“No, I'm pretty sure he can get us home,” Fitz said. Donna nodded in confirmation. “We just travel with him. Adventure and all.”
“Oh, goodness.” Susan blinked at them. “I knew Grandfather was starting to like people more, but I never thought he'd choose to travel with anyone else.”
“Grandfather?” said Donna.
“...is your grandfather?”
“Well, yes,” said Susan, “Oh, I do wonder what's happened if neither of you have ever met me... I hope I'm all right. Running into your own timeline can be devilishly complicated. I'm not entirely sure how it works in terms of temporal mechanics, but it does make my brain hurt a little.”
“The universe is probably in danger of exploding. There are at least four TARDISes...” said Fitz, sighing. A granddaughter. The Doctor had children.
“Two here, my Doctor landed by a shop...” Donna knocked on the door of the mysterious fourth TARDIS.
“Mine landed in a dumpster,” said Fitz.
“That does sound like Grandfather,” Susan admitted. She stood behind Donna. “I have a key— I suppose it'll still work...”
The door opened. A man with a leather jacket— Fitz was struck by its similarities to his own— and large ears poked his head out. “Yes?” he said.
The man noticed Susan, and it was as if someone had punched him in the gut. “Susan,” he whispered.
“Grandfather?” Susan wrapped her arms around this new Doctor, resting her head on his chest. “How long has it been for you? I'm here with Ian and Barbara, and this is Donna Noble, and that's—”
“Fitz,” said the new Doctor. Fitz raised a hand and grinned.
“Doctor,” he said. He couldn't imagine a man more unlike his Doctor— hair cropped intead of long and curly, dressed more like Fitz himself than the Doctor.
But there was something in his eyes. Something old, and kind, and Fitz knew this was the Doctor.
“You're not the Doctor,” said Donna. “The Doctor's all... skinny. Wears a suit. Hair like...” Donna made hand gestures to demonstrate the Doctor's hair.
“I'm a Time Lord,” said the other Doctor, holding Susan close. “Sometimes, we get a new face, new mind... Same man, though. Mostly.”
“There's at least four of you running around here,” said Susan. There was a worried look on her face. Something was going to happen to her— something that had made this Grandfather hold her like he would never let go.
“Fitz and I think it means something's going to try to kill us,” said Donna. She wasn't nearly as sure as Fitz or Susan about this Doctor. If somebody might go and change their face on you, Donna thought it was only polite for them to warn you quite far in advance. How was that even meant to work? Did he just take off one face and put on another whenever he pleased?
“Most things do,” Fitz pointed out.
“Don't know why I put up with it, honestly...” Donna sighed. If something was going to try to kill her, she'd have liked it to hurry up, please and thank you.
“I'm standing right here,” the Doctor pointed out. “Now, why don't we get into my TARDIS and figure out what's going on?”
“That sounds like a good plan, Grandfather.” Susan smiled up at this Grandfather, doing her best to hide the pit in her stomach. What was going to happen to Grandfather? What was going to happen to her?
As they were about to step into the TARDIS, Donna took Fitz's wrist. “About this whole granddaughter thing.”
“Yes?” Fitz just managed to peek inside and see a totally different TARDIS— like a metallic forest, and not the cross between a library and cathedral he knew. Susan gaped at it, then quickly rushed to assist the Doctor at the console. They smiled at each other and took places across the console. Yes. Yes, Fitz could believe that was the Doctor's granddaughter.
“The Doctor— my Doctor, the skinny one— well. He said he was the last of his kind.” Donna turned to watch this Doctor and Susan discuss the readings with each other. “Don't you think his granddaughter would be a part of that?”
“Oh.” Fitz could feel a lump rising in his throat. “So you're saying...”
“Well, it wouldn't explain everything. But...” Donna sighed and shoved her hands in her pockets. “Seems like a sweet girl.”
“She does,” Fitz agreed, “and if you're right...”
“Fitz!” called Susan, “Donna! Come look at these readings! If I'm right...”
“Then we're looking at...” the Doctor added, pulling a lever.
Sam Jones skidded into the TARDIS, putting an arm around Fitz and Donna. She was followed by another woman (Fitz thought she was probably from his own time), Fitz's Doctor, a skinny man who was probably Donna's Doctor, and an old man. “Trouble,” said Sam. She pushed Donna and Fitz into the TARDIS, and the woman and probably-Doctors followed.
“What have you done to the place?” the eldest demanded, shaking a walking stick.
“Hello again, Fitz! Susan!” Fitz's Doctor beamed and shut the TARDIS doors along with Donna's Doctor.
“Hello, Grandfather, Grandfather, and Grandfather.” Susan held back a giggle. This was a grave situation. “Barbara!”
“Sam Jones,” said Sam, not wanting to be left out of the fun.
“What's the meaning of all this?” demanded the Doctor in leather.
“Well, if we're right,” said Fitz's Doctor.
“And I usually am,” continued Donna's Doctor.
“Then we, young man, are about to fall through a tear in reality itself!” finished the eldest Doctor. “Now, where's Chesterfield?”
“Our TARDIS, Grandfather.” Susan turned to the companionless Doctor. “See, I said it was a tear in reality.”
“Tear in reality,” said Fitz. “Wish I could say that was new.”
“Fitz!” Donna's Doctor said excitedly, grabbing hold of him. “And Sam Jones! And... Barbara! Susan!” The Doctor bounced along to grab onto all his old friends and beam.
“Yeah,” said Fitz, “that's definitely the Doctor.”
“Well, he should better be,” said Donna, charging up to him. “Why didn't you tell me you could change faces?”
“Well, it's not exactly easy to bring up in polite conversation,” Fitz's Doctor broke in. “Hello, have I met you yet?”
“Will you stop this idle chit-chat and help me keep us from falling through a tear in reality?” the eldest Doctor demanded.
The TARDIS swung violently to one side, then the other. “And what exactly have you done to the place, hmm?” he demanded, ignoring the fact that gravity had forced most of the others onto the wall.
“I don't like it,” Fitz's Doctor agreed from under Fitz.
"I do." The companionless Doctor rolled his eyes.
“Ten seconds until we hit the rift,” Susan said anxiously. “Oh, Grandfathers, do something!”
“Would you mind getting off me?” Barbara asked Donna's Doctor.
“Barbara!” he said, not getting off her. “Lovely to see you again.”
“Lovely to— now I know these aren't the Doctor.”
“We're going to die,” said Donna.
“We aren't going to die,” said Fitz's Doctor nonchalantly, “I can't die before I become me, or him, or him. I haven't been either of you, have I?”
“No!” both Donna's and the companionless Doctor agreed.
“And so obviously we aren't going to die.”
“Unless that caused the tear in reality,” the companionless Doctor pointed out.
“Seven seconds.” Susan gripped onto the console, looking between Doctors. “Oh, Grandfather, there must be something we can do!”
The TARDIS tilted violently, and everyone was thrown into the console.
“Sorry,” said Sam Jones, grabbing onto Susan's legs.
“What if we go into reverse?” Donna asked, pressed against the eldest Doctor.
“That isn't how it works,” said Fitz's Doctor, clinging tight to both of his future selves.
“Well excuse me for trying to save us!”
“We're going to die,” Fitz said, squeezed against the console by everybody else.
“Four! We are not going to die. Grandfather will think of something...”
“Of course we're not going to die!”
“We'll just be trapped outside of reality for all eternity.”
“Well, at least we'll all be together.” Fitz's Doctor beamed.
“Oh, God, eternity with four of him,” Donna moaned.
“One,” said Susan, reaching across the console for her grandfather.
