A/N - Wow guys, your response to this story has been amazing! The next story called The Woman Who Killed The Master has now got it's first chapter up so go have a look! :)
Zara pulled out of the hug, her and The Doctor moving and using the controls when The TARDIS suddenly spun out of control and a klaxon blared, sending The Doctor and Zara flying. The Doctor struggled back to the controls, pulling on a lever and making The TARDIS calm down.
"Stop that! Stop it!" He called. "What was all that about, eh?" He reached up and tapped the time rotor. "Eh? What's your problem?"
He moved over to the controls and Zara's eyes widened as she watched as The Doctor in his fifth form, made his way around the console, "Right, just settle down, now..." He called to The TARDIS, bumping into Ten.
"Excuse me..." Ten apologised.
"So sorry..." Five muttered, the two moving past each other before stopping to look at each other.
"What?"
"What?"
"What?"
"What?!" Zara gasped sarcastically, laughing as the two Doctors looked at her.
Five looked back at Ten, "Who are you?"
"Aw, brilliant!" Ten grinned.
Zara moved over to the two of them, looking between them, "I mean, totally wrong, big emergency, universe goes bang in five minutes, but..." She laughed. "Brilliant!" She looked over at Ten. "It's you!" She whispered, nodding at Five.
"I'm the Doctor, who are you two?" Five snapped.
Ten grinned, chuffed, "Yes, you are, you are the Doctor."
"Yes, I am, I'm the Doctor."
"Oh, good for you, Doctor. Good for brilliant old you."
Five looked at Zara, "Is there something wrong with him?"
Zara shook her head, smirking.
"Ooo, there it goes, the frowny face!" Ten grinned. "I remember that one! Mind you," He grabbed hold of Five's face, squishing his cheeks. "It's saggier than it ought to be," He fiddled with his sideburns. "Hair's a bit greyer."
"That's cos of him, though," Zara clarified. "The two of you together has shorted out the time differential, should all snap back in place when we get you home." She nodded to Five.
Ten grabbed his lapels, trying to shut his coat, "Be able to close that coat again. But never mind that, look at you! The hat, the coat, the crickety cricket stuff, the..." He glanced at the stick of celery on his jacket. "Stick of celery, yeah... Brave choice, celery, but fair play to you, not a lot of men can carry off a decorative vegetable."
"Shut! Up!" Five snapped, making Zara laugh as he snatched off his hat in anger. "There is something very wrong with my TARDIS, and I've got to do something about it very very quickly, and it would help, it really would help, if there wasn't some skinny idiot ranting in my face about every single thing that happens to be in front of him!"
Ten looked at Zara, pouting, "Am I skinny ranting idiot?" Zara giggled, shaking her head. He looked back to Five, "Oh, okay. Um, sorry. Doctor."
"Thank you." Five sighed, turning back to the console.
Ten glanced at the back of Five's head, "Aw, the back of my head!" He cheered enthusiastically.
"What!?" Five called over his shoulder.
"Sorry, sorry, it's not something you see every day, is it, the back of your own head. Mind you, I can see why you wear a hat... I don't want to seem vain, but could you keep that on?"
Five turned back to face him, "What have you done to my tardis? You've changed the desktop theme, haven't you?" He glanced around the console room. "What's this one? Coral? It's worse than the leopardskin." He reached into his pocket and pulled out a pair of half moon spectacles, putting them on and turning back to the console.
"Aw, and out they come!" Ten cheered, bouncing on his toes. "The brainy specs! You don't even need them! You just think they make you look a bit clever!"
A klaxon sounded.
"That's an alert... Level five." Zara and Five said in unison.
Five stared at Zara in shock as she continued, "Indicating a temporal collision!"
"It's like... two tardises have merged, but there's definitely only one TARDIS present..." He finished, confused. He pulled his gaze away from her as he rushed around, pressing buttons. Ten strolled across, leaning on the scanner, watching him as Zara moved round and stood on his other side. "It's like two time zones at war in the heart of the tardis... That's a paradox. Could blow a hole in the space-time continuum the size of..."
"Belgium." Zara smiled, making Five frown at her and Ten beam at her proudly. She thought about it for a moment, "Yeah, Belgium, I'm pretty sure." She reached out across both Doctors and pulled over the scanner to show Five.
"That's a bit undramatic, isn't it?" Five frowned. "Belgium?"
Ten pulled out the sonic as Zara took out The Master's laser screwdriver, "Need this?" He asked, the two of them holding them out to Five.
"Nah, I'm fine."
"Oh no, of course," He threw the sonic in his hand before putting it back in his pocket as Zara gently threw The Master's laser screwdriver onto the console. "You mostly went hands free, didn't you, like 'eh, I'm the Doctor, I can save the universe using a kettle and some string, and look at me, I'm wearing a vegetable'."
Five stalked over so he was nose to nose with Ten, "Who are you?"
"Take a look." Zara said softly.
"No." Five said after a pause. "Oh, no..."
"Oh, yes." Ten nodded.
"You're... oh, no..."
"Here it comes... yeah, yeah, I am..."
"A fan."
"Yeah..." His eyes widened suddenly. "What?" Zara looked at him, stiffling a laugh.
The console beeped, making Zara stop laughing and look over, "Level ten, now."
"This is bad." Five stressed. "Two minutes to Belgium!"
"What'd'ya mean, a fan?" Ten asked. "I'm not just a fan, I'm you!"
"Okay, you're my biggest fan. Look, it's perfectly understandable, I go zooming around space and time, saving planets, fighting monsters, and being, well, let's be honest, pretty sort of marvellous..." Ten nodded in agreement. "So naturally, now and then, people notice me. Start up their little groups. That LINDA lot. Are you one of them? How did you get in here? Can't have you lot knowing where I live..."
"Listen to me, I'm you. I'm you with a new face." He slapped his own cheeks. "Check out this bone structure, Doctor, cos one day you're gonna be shaving it."
The cloister bell suddenly sounded.
"The cloister bell!" Five called.
"Yep, right on time." Ten nodded. "That's my cue..." He moved over to the controls.
"In this limit, we're gonna generate a black hole strong enough to swallow the entire universe!"
"Yeah... That's my fault, actually." Zara quickly explained. "I was helping you, well the future you, rebuild the TARDIS, cause you can't do it on your own-"
"Oi!" Ten pouted.
"Forgot to put the shields back up. Your tardis and his TARDIS... well, the same TARDIS, different voyages in the same time stream, collided and wurp, there ya go, end of the universe, butterfingers-"
"But, don't worry, I know exactly how this all works out, watch..." He looked at Zara laughed, suddenly realising what she had to do and began to fiddle with the controls.
"Venting the thermo buffer... Flooring the helmic regulator... And just to finish off, let's fire those zyton crystals." She laughed.
Five tried to pull her hands away,"You'll blow up the TARDIS!"
"Only way out." Ten shrugged.
"Who told you that?" Five frowned at him.
"You told me that!" He hit the last button for Zara and everything turned white, before everything returned to normal.
Five looked at the scanner in awe, "A supernova and a black hole at the exact same instant..."
"Explosion cancels out implosion." Zara laughed.
"Matter remains constant."
"Brilliant." Ten grinned at her, placing a kiss to her head.
"Far too brilliant." Five said in awe, staring at Zara. "I've never met anyone else who could fly the TARDIS like that."
Ten smiled, putting his arm around her, "And you probably never will."
"You didn't have time to work all that out. Even I couldn't do it!" He looked to Ten. "And how could you have known she would have worked it out?"
"I didn't have to know. I didn't have to."
"You remembered."
"Because you will remember."
"You remembered being me, watching her doing that... You only knew she would know because I saw you do it."
"Wibbly wobbley..."
"Timey wimey!"
Zara laughed, raising his hand to high five him, only for Five to stare back. Zara shook her head, high fiving Ten with a laugh before another alarm sounded and he lept to the console.
"Right! Tardises are separating." He called. "Sorry Doctor, time's up, back to long ago. Where are you now? Nyssa and Tegan? Cybermen and Mara and Time Lords in funny hats and the Master? Oh, he just showed up again, same as ever."
"Oh, no, really?" Five asked as Ten shot Zara an apologetic look. "Does he still have that rubbish beard?"
"No, no beard this time. Well, a wife. And a daughter. Well, same daughter twice." He smiled at Zara. "She's a bit of a mysterious paradox isn't she?" He mumbled. "The Zarantheon paradox." Zara smiled softly back at him.
"Oh." Five said as he began to fade, catching their attention. "I seem to be off. What can I say? Thank you. Doctor."
"Thank you."
"I'm very welcome." He dissappeared.
Zara ran over, grabbing Five's hat that he'd left on the console, throwing it to Ten and flipping a lever, making Five reappear.
"You know," Ten began, handing him the hat. "I loved being you. Back when I first started at the very beginning, I was always trying to be old and grumpy and important, like you do when you're young. And then I was you. I was all bashing about and playing cricket and my voice going all squeaky when I shouted, I still do that! The voice thing, I got that from you!" Five smiled at him and put on the hat. "Oh!" Ten put his foot up on the console, showing Five his shoes. "And the trainers! And..." He pulled out his glasses from his pocket, wonkily shoving them onto Zara's face. "Snap!" He pointed at them as Zara laughed, putting them on herself properly. "Cos you know what, Doctor? You were my Doctor."
Five raised his hat, "To days to come."
"All my love to long ago."
Five disappeared and Ten smiled at the empty space.
"Oh, Doctor?" Five's voice called. "Remember to put your shields up."
Zara laughed, hitting a button when suddenly The TARDIS roared, throwing The Doctor and Zara to the floor, the wall smashing as the front of a boat ripped through the side of The TARDIS.
The Doctor coughed, pulling Zara closely to him as she reached out, flipping over a rubber ring that had landed next to her, looking at the black lettering that read TITANIC.
"What?" The Doctor spluttered as Zara stared at it, amused. "What? What?"
