A/N: Uuuuhhhhh I kind of don't know what to say… erm, I couldn't help this from happening. This is a crossover between my A2A fic series and Doctor Who. I know being in the crossover section some new readers might wander in and wonder what the hell is going on… basically I've been writing a series of Ashes to Ashes fics for almost 3 years so I totally understand that it won't be of interest to many, this is only going to appeal to a tiny percentage of my readers, but that's OK, I just wanted so badly to write this. For the two people I know will be reading, I hope this meets expectations!

Prologue

"Don't even think about it, Drakey."

"What?" Alex frowned innocently as Gene leaned back against the soft interior of his Aston Martin, waiting for the lights to change.

"'Feels like a strange day', that's what you said."

"Well it does!" Alex shrugged.

"No need to say it out loud!"

"Why not?"

"You've cursed us now, Bols," he told her, "you let those painted lips flap once too often and we're going to have plagues of locusts and be awarded a Michelin star for the bloody canteen sprouts."

"Oh don't be so silly," Alex pushed her hair back behind her ears and laid her head back against the head rest, "I just commented –"

"That the fabric of me world is about to tear and let all the loonies through."

"Gene!"

"You might as well have done, Bolly," Gene warned, "you know what this place is like. One minute we're combing the streets to clear up the dirt in the gutters, the next we've got a bloody circus unloading in the car park."

"Gene, once that happened," Alex told him firmly, "and you know that was only because one of the elephants escaped."

"Bammo didn't have be befriend the bloody thing though, did he?" Gene began to turn a little red with anger as he recalled the incident from some weeks earlier, "flicking it peanuts out the widow, no wonder the sod didn't want to move on."

"Is that juggling club still stuck in the ceiling of the gents?" Alex asked.

"Nope."

"Who got it down?"

"Whoever the poor sod is that's been out cold in a coma for the last two weeks," Gene mumbled, hoping health and safety hadn't caught wind of the incident. He cleared his throat and began to move again as the lights changed and the traffic began to clear, "I'm not taking any chances Bolly. The minute you start saying the day feels a bit coco-loco I start building a nuclear shelter and going into hiding."

"Oh poppycock," Alex folded her arms.

"It's only ten in the blinking morning and we've already put in a bloody day's work," Gene reminded her, thinking of the raid they'd pulled off successfully in the early hours of the morning "let's just show our faces, stamp a few papers, slap a few twats and get back to bed before Neighbours comes on the ruddy TV."

"You watching Neighbours?" Alex frowned, then settled back tiredly in her seat, "I told you today felt weird."

"Doctor, is that supposed to be flashing?"

The Doctor noted Clara's concerned expression as she regarded the Tardis with suspicion.

"The question is," he began, "what is anything 'supposed' to be doing at any given point?" he rushed across to her, almost weightlessly gliding through the air, "when you ask if it's supposed to be doing something you're putting your own boundaries and restrictions on it… and in fact on anything else in the universe... If you believe that it could not, would not or should not be flashing then you're stunting the growth of the possibility. By denying that it's allowed to flash are you stopping it from flashing or simply expressing your own belief that it shouldn't be flashing? It's a universe were so many possibilities exist, we must not try to limit them with our should and should nots!" his eyes turned to a glowing area on a panel and a feeling of dread and anxiety came over him. "But," he swallowed, "that shouldn't be flashing. No."

Clara's eyes opened wide and she looked at him in alarm.

"What does that mean?" she asked.

"It means," the Doctor spun around, jumping between areas of the room to check on every display he could see, "that you might want to hold on tightly."

Clara froze.

"And are you going to share the reason for that?" she asked, sounding a little more alarmed with every word.

The Doctor finished leaping about and came to a halt in front of Clara, laying a hand on her arm. He looked her in the eye and told her seriously,

"Because we've hit an anomaly that's going to make Alton Towers seem like a relaxation tank," he told her.

"What do you mean an anomaly?" Clara demanded.

"If I knew that it wouldn't be an anomaly!" The Doctor told her, "I'd have a nice, reasonable explanation for what was about to occur instead of vaguely naming it an 'anomaly'!"

"You're still not telling me what's about to occur!" Clara said through gritted teeth as they began to experience some turbulence.

"We're about to enter the fifth dimension," the doctor cried and Clara shook her head.

"That was at Chessington, not Alton Towers!" she cried.

Their ride began to resemble the inside of a blender.

"The fourth dimension is time," the Doctor cried grasping the closest object to keep him steady "now we're encountering fifth dimensional space!" he shook his head, unable to work out what had suddenly gone so wrong, "parallel dimensions! Other universes that parallel our own."

"We're entering another universe?" Clara clutched his arm as her feet started to lose their grip on the trembling, juddering ground.

"More or less."

"More or less?"

"Yes. More or less. Less or more."

"Meaning?"

The doctor swallowed. For once he felt out of his depth.

"I don't know," he uttered.

As the Tardis swerved and curved and jumped to a universe whose pull proved too great to decline those were the three scariest words that Clara had ever heard.

"What's that noise?"

Robin stopped still in the doorway of CID. He'd only been bringing up a few papers but the strange sound stopped him in his tracks.

As Simon pretended he wasn't really using Bammo as drawing pin target practice he looked up a little blankly.

"What noise?" he asked.

"That noise!" Robin held up a finger as though that was supposed to help.

"I can't see the noise, even if you point!" Simon complained and Robin sighed.

"Never mind, must just be an alarm or –"

But before he could finish his sentence the dull throbbing noise began to get a little louder and Simon froze.

"Wait, no, I can hear it now," he said.

"What is that?" Robin looked around, glancing accusingly at one of the nearby computers in case the hard drive was going into meltdown, but as the volume increased his eyes rose and focused on the window. "What's going on out there?" he frowned.

"I don't know," Simon walked at quite a pace towards the window and peered outside. To Robin's dismay his face paled visibly and took on a look of distress. "No."

Robin hesitated.

"What?" he asked.

"You have got to be fucking…" Simon swallowed and blinked, trying to clear the large blue item from his field of vision as it slowly faded in and out, accompanied each time by a wave of noise, "kidding me."

"What?" Robin asked again as Simon spun around.

"Someone's having a bloody joke!" he declared.

"Why?" Robin frowned, making his way towards the window, "What's actually ou-"

But before he had a chance to finish his question an almighty boom sounded as the walls of reality found themselves smashed to pieces and a little blue box finally thumped to the ground through the tear that resulted.

All at once a shockwave travelled through the station, through the life that Gene's world had given every one of the men and women who worked within it. Eyes closed, muscles failed and bodies fell as a mass-fainting incident rendered the officers and detectives unconscious.

Outside, a door slowly opened and two faces peered out.

This was not good.

They'd fallen ungracefully into the wrong dimension, they'd taken up some head honcho's parking space and above everything a horrid smell was wafting toward them from the canteen.

Worse than that, there was no chance on earth that the sonic screwdriver was going to work on sprouts.

A/N: If you're wondering where this fits into my fic series it DOES have its place in canon, it's set after The Power Of Goodbye which I've only just started writing but there will be nothing in here that spoils anything coming up! This crossover is set on May 1998 :)
