Once Melanie, Izzy, and their backpack were safely inside, the twins slumped up against the door in a collective sigh of relief. Without warning, the TARDIS started to shake and crash. The twins exchanged a glance and lunged for the nearest handrail. Izzy and Melanie squeezed their eyes shut as the Doctor frantically pushed buttons and flipped levers.

"WE'RE GOING TO CRASH!" They could hear the Doctor shout.

Donna screeched in reply, "YOU DON'T THINK I BLOODY KNOW THAT, SPACEMAN?!"

The Doctor ignored her. "MORE IMPORTANTLY, WHY ARE WE CRASHING?! YOU'D ALMOST THINK WE'D LANDED IN ANOTHER PARALLEL UNIVERSE!" he yelled over the noise of stuff crashing all around them.

All of a sudden, the lights went dead, and the shaking and crashing stopped. Using each other as support, Izzy and Melanie shakily got up.

"Are you okay, Donna?" The Doctor's estuary English accent could be heard through the silence.

"Yeah, I'm okay, spaceman," came Donna's reply.

Melanie spoke up too. "We're okay too, If anyone asked."

They heard a thump and a few bits of metal clanking against each other. "What? How'd you get on the TARDIS?" The Doctor ran up to the source of the noise.

"We walked through the doors, like any sensible person would." Izzy responded. Good. I'm actually able to clearly talk to him now. Getting a grip.

"Ahhh, OH, you're the twins I met!" the Doctor slapped a palm on his forehead. "How did you two know to come to the TARDIS when it landed? Normally people don't even notice, but you two came running!"

Melanie's grip on Izzy's hand tightened. "Don't tell him about the show Izz, not yet," she quietly whispered into Izzy's ear.

Izzy gave her a silent nod, not that she'd see it, but just because. "We heard a weird noise, and with all the aliens and stuff, we thought one had finally landed in the states. We got...excited," she told the Doctor.

There was a pause in the conversation.

"Okay! Right then! I can turn on the emergency backup lights by reversing the auxiliary feedback loops and re-initialising the command structure!" The Doctor's shoes could be heard thumping up to the TARDIS console, following be the whirring noise of the sonic screwdriver.

"What?" was all Donna could say before some lights came on, casting a dim yellow glow into the console room.

Izzy and Melanie looked around in absolute awe. This place was so much bigger in real life!

"Right then! Power! And as a bonus, we're back in our home universe!"

Izzy silently gasped. Parallel universes! So that's how any of this could possibly be real! Didn't someone say once that there were infinite parallel universes, so logically that should include fictional ones?! OH, we are GOOD!


Melanie glanced over at her twin, who seemed to be having an "a-ha!" moment. After a quick moment of indecision she walked over to the Doctor, who was at that moment tinkering with some stuff under the TARDIS console.

"Anything I could help out with?" she asked.

"Er, no, not much right now. But, I'm quite surprised at how well you're taking all of this in. Usually everyone stares around in awe and says, it's bigger on the inside," the Doctor replied.

Melanie smiled, thinking about Clara saying it's smaller on the outside. "I can't imagine the amount of times you have that conversation. One day you'll get so tired of hearing that that you'll just say, 'yes, it's bigger on the inside, no, I don't have time to talk about it!'"

The Doctor looked up at Melanie from under the console. "That's actually a great idea. I'll probably just say that next time then!"

The conversation was interrupted by a cascade of sparks coming from the top of the console. Everyone besides the Doctor jumped a bit, startled by the sudden light show.

"HA!" The Doctor shouted. "Got'cha!"

Donna looked at him questioningly from across the room. "What did you do this time?"

"I rerouted a few wires and leads in the dematerialisation circuit, don't worry I have a spare, so we'd end up at..." he got up and ran to the doors, "Cardiff Bay!"

With a flourish, the Doctor opened the TARDIS doors revealing the dazzlingly blue sky outside. "Which happens to be right on top of a rift in time and space that can boost the power in the TARDIS!"

Izzy, having finally regained her bearings, walked up to the others and said, "So, anyone up for some fish and chips while we're here? I'm starving!"
