The four of them moved back towards the TARDIS, the Doctor and Rose with their arms snaked around each other's waists at the front, Jack and a very flirty Donna behind. Just before they got to the TARDIS, the Doctor stopped and grinned at Rose.
"Check it out," he said, raising his free hand to click.
"Woah, stop right there Doctor," said Rose, slightly worried. "If you've gone and got one of those stupid holes in your head like Adam, I really don't want to see it."
The Doctor looked put out. "Just because I'm good looking," he said with a wink, "doesn't mean I'd go and do something stupid like that so called 'genius' that you liked."
"You are so full of it!" laughed Rose. "Anyway, what were you going to show me?"
"Oh, just a little trick I learnt in a library," said the Doctor. He then raised his hand, and clicked.
As the TARDIS doors swung open, Rose gasped. The Doctor took advantage of her shock to sweep her up in his arms and carry her in.
"Welcome home," he said, as he carried her over the thresh hold into the TARDIS.
"Aren't you supposed to do that for brides?" she asked, grinning up at the Doctor as he placed a kiss on her head and set her on her feet.
"Well..." he said, rubbing the back of his neck, "I'd better remember that then."
Before Rose had a chance to respond, the Doctor had bounded off to the TARDIS doors. "Come on, you two, haven't got all day!" he yelled at Donna and Jack, who were taking their time. "The Daleks will find us if you two don't stop flirting."
Donna and Jack ran through the door as the Doctor dashed around the console. He jumped around like Tigger on red cordial, flicking switches with an enthusiasm not seen since before Canary Warf. He ran to the other side of the console to flick the temporal stabiliser, only to find that Rose had got there first.
"Got it," she said, grinning. The Doctor's face lit up as Rose flicked the switch, her tongue poking out at him.
He bounced over and pulled the leaver, sending the TARDIS in to flight with a massive "Allons-y!"
Rose laughed. "You still say that?" she said.
"Oh yes!"
"He never really shuts up about it," piped up Donna, who had been leaning against the railing with Jack, watching the reunited couple with an amused expression.
The Doctor flung his head around with a startled expression, having forgotten that there were others on the TARDIS. Rose saw his expression and burst out laughing, recalling the time he forgot that Mickey had been holding down a button for half an hour.
"Yeah, we're still here," drawled Jack. "Got a plan?"
"Hmm... Daleks. Should be able to get a better view, hold on." He fiddled with some dials went over to the display, pulling out the brainy specs before taking a closer look at the screen.
"That's a lotta ships." noted Donna, peering over his shoulder.
"Hold on, what's that?" Rose asked, pointing to a flashing point on one of the ships at the centre.
The Doctor zoomed in. "Seems to be some sort of signal, that controls the whole lot,' said Jack.
"The Dalek Crucible!" cried the Doctor. "I've heard of these, they're like the mother ship of the Dalek fleet. Everything that the Daleks do is controlled from there!"
Rose caught on quickly. "So if we want to stop the Daleks..."
"...we have to get to the controls!" finished the Doctor. Jack chuckled at how easily the Doctor and Rose slipped back into their old ways, finishing each other's sentences.
"So hold on a minute..." said Donna. "There are these really dangerous things called Daleks, who want to kill you, and you want to fly directly in to the heart of their operation?"
"Yup," replied the Doctor.
"Pretty much" agreed Rose.
"Well, what are we waiting for?" yelled Jack, cocking his gun.
"You're mad, the lot of you," said Donna.
The Doctor replied with a manic grin before flicking a switch on the console, sending the TARDIS into the heart of the Dalek crucible.
