A/N: I am so, so sorry this has taken so long! I mentioned last time that I was having probems with my ME and just after I posted that chapter I caught a bug and it made it worse! So I was quite ill for a few weeks, then I went on holiday to Cardiff. Now I'm back and feeling ok, so on with the show!

The two Roses crept carefully up towards a door that was covered in high-tech security locks from top to bottom.

'I might be stating the obvious here, but it seems that this door leads to something we're not supposed to get to.'

Rose chewed her lip for a second.

'We're getting through it though, right?'

'Oh, yeah. Absolutely.'

They both stood back from the door and eyed it curiously, remaining silent as they thought.

Rose looked up, and her eyes caught sight of the ventilation shaft. It seemed funny to her that a room so heavily locked up could be easily reached by a shaft. For all their brains, these aliens weren't very bright. She'd seen it before of course; aliens quick to show off their superior technology without a second thought. Did they really think humans were that stupid?

Rose eyed the door one more time, then glanced across to her partner in crime.

'Ventilation shaft?'

'Sure.'

'Dad!' Isabelle whispered urgently.

'What?' he replied, not looking around as he dragged her up another corridor.

'Dad!' she said a bit louder this time. 'Stop.'

Alex stopped and turned to look at his daughter.

'What is it?'

'Back there. I thought I saw something on the ground.'

'Saw what?'

'I don't know but it might be important,' she insisted, dragging him back towards the direction they had come from.

There, poking out unassumingly from behind a corner on the floor, was the shiny side of what looked suspiciously like…

'Jack's pistol!' Alex ran over and bent down to pick it up.

'That means we should go this way instead, right?'

'Right!' He put the small pistol in his pocket and grabbed Isabelle's hand, leading them both down another maze of corridors.

Rose peered down from inside the ventilation shaft. It hadn't been the easiest of things to open, but compared to the door, it was a breeze.

She steadied herself, and reached back down outside the vent, grabbing the hands of her other self and pulling her up.

'Ok?' Rose puffed as she leant back against the cold, metal wall.

'Yeah.'

A noise from down below made them jump, and the girls scrambled to close the grate back over the shaft entrance.

'That was close,' Rose whispered, and they peered through the grate carefully to see what was going on.

Trolon was down below with two guards. They watched him as he swiped four different cards over the locks and let the guards push the heavy door open. Once they'd disappeared inside, the girls shuffled up the shaft as quietly as they could. It didn't take long to reach the grate above the room, and when Rose looked down she gasped.

'What is it?'

'The Doctor,' she whispered. 'And Jack. They're shackled to a wall.'

'The Doctor?'

Rose saw the questioning look in her eyes and shook her head sympathetically.

'Not mine,' she said sadly.

Rose grabbed her hands and looked in her eyes. 'He doesn't know you're alive,' she said gently. 'But you will see him again. I'll make sure of it.'

'So, Doctor,' Trolon sneered. 'It would seem your time is up. What do you have for me?'

The Doctor screwed up his face in thought. 'Um, well… nothing really.'

'Nothing? Is that so?'

'Yeah. Mind you, I've got the answer, I just don't want to give it to you.'

Trolon's eyes narrowed.

'Something wrong?' Jack said.

'You have the chance to escape with your loved ones, but instead you would sentence them to death?'

The Doctor smiled. 'You're not getting the answer. And they are not going to die. Nobody is going to die.'

Trolon looked furious and stormed right up to the Doctor, coming nose to nose with him.

'Give me the calculations!' He spat.

The Doctor idly put a hand up to his face and wiped it.

'Would you kindly refrain from spitting on me.'

Trolon's face went bright red and he smacked the Doctor across the face.

Now the Doctor was angry.

'You will GIVE THEM TO ME!'

'NO I WILL NOT!' The Doctor yelled back in his face.

This stunned Trolon for a second and made him step back. Then he looked to Jack, who was grinning as if he knew something Trolon didn't.

'What are you smiling at?' Trolon commanded.

Jack's grin got even bigger.

'You're about to get your ass kicked.'

Before Trolon could reply, the two Roses jumped from the vent in the ceiling, landing on top of the two guards.

'Rose!' the Doctor cried.

'Do something!' Trolon shouted at the guards.

However, having been caught unawares, the guards were now passed out on the floor.

Trolon let out an angry shriek and stuck his hand in his pocket, pulling out what looked like a small button. Standing in front of the Doctor and Jack to guard them from the two women, he raised his fist in the air and pressed it.

'You want a fight? Well, you've got one.'

The two Roses looked at each other, then at Trolon.

'Bring it on.'
