Castle followed Beckett through the twisting corridors keeping close to her, though after a while it was clear that they were completely lost, as they circled past the pool for the third time.

'There could be three pools?' Castle asked rhetorically trying to make Beckett feel better.

'Castle even if there were we didn't pass three on the way here.' she said frustrated. All the corridors looked the same but Beckett was sure they were different when they were first in them. Beckett had been fairly certain of most of the route they had taken and yet at every turn it seemed as though it was different to before. All the artifacts and rooms had changed places. When they had stopped outside the swimming pool for the third time she was starting to suspect it was more than a hunch. 'I think it's changing.' she voiced her concerns. Both she and Castle had felt the TARDIS's presence from the beginning but to think that it was getting them lost on purpose. Was that even possible? Castle looked at her puzzled seeing his look of confusion she continued. 'The layout of the corridors and the rooms I think somehow they are being moved around.'

'Like an endless shifting maze trapping us here forever.' he said concerned.

'Castle that's not helping.' she said.

'But why? Because we wandered off?' Castle pondered aloud. Beckett shrugged. She didn't know anymore than he did. 'We are sorry. Can we get back now?' Castle tried. An echoing alien bang emanated from the corridor leading right from the swimming pool. 'Okay.' Castle said trying to sound confident. 'This way.' Beckett tried not to laugh as Castle put on a serious face and began striding down the corridor.

Nearby Jack and the Doctor were getting close to where the TARDIS scanner had sent them Jack now following the Doctor as they ventured further and further into the TARDIS's infinite interior. The Doctor held out his sonic screwdriver sweeping the corridors to track their signal. Jack dropped behind watching the Doctor as he rapidly made his way through the corridors. Again Jack stifled a laugh. The Doctor glanced at him questioningly.

'Still got a great bottom.' Jack flirted.

'Oi, that's not why you're here! The Doctor turned to face him. 'Besides you never brought me that drink!' he joked. Jack grinned.

'Well there are some excellent bars in Cardiff.' he winked.

'Better find Castle and Beckett first, they cant be far we are nearly there.' The Doctor said smiling before turning round once more to scan for them. It was only a few meters before the sonic screwdriver began to emit a high pitched sound in place of its usual buzzing. The Doctor span round to face Jack. 'Aha! There we go!' The Doctor exclaimed, 'They should be nearby, and remember what I said no spoilers.' The alien banging echoed down the TARDIS corridors and the Doctor understood immediately. 'Thanks dear.' he whispered. 'This way Jack.'

Castle and Beckett had been walking down the same corridor for about ten minutes now and Beckett was waiting for Castle to admit defeat.

'Okay.' Castle stopped. 'We're back where we started.' He moved out of the way to reveal the same ornate wooden door. Beckett sighed. 'What do we do now?'

'I don't think the TARDIS wants us to leave.' She said annoyed. Castle opened the doors.

'I can think of worse places to get stuck.' Castle said inviting her inside. 'The Doctor is probably looking for us now, I bet the TARDIS is keeping us here to help him find us.' It seemed reasonable enough she thought but the idea of sitting, waiting, not doing anything!

'Castle, there must be something we can do?' she asked rhetorically following him back into the field. She looked around at their beautiful surroundings. 'I suppose we will be okay here for a bit.' she conceded. Castle stared into Beckett's eyes as she sat back down in the soft grass.

'It's okay, you don't have to save the day all the time, even super heroes get days off!' he said gently putting a smile on her face.

'So I'm a super hero? What powers do I have then Castle?' she asked raising her eyebrow questioningly; putting him on the spot. He thought about it for a moment before replying.

'Whatever powers you want.' he grinned, sitting down beside her. 'What power would you have?'

'I don't know.' Beckett said thoughtfully.

'You don't know!' Castle said shocked. 'You've never even thought about it?'

'Well yeah I've thought about it, I've just never decided. Maybe telepathy, it would make it a lot easier to solve cases. What about you then Castle? What would be yours?'

'Oh that's easy! Selective telepathy and empathy.' Castle said confidently. 'To be able to understand people, get inside their head, really understand their character. Then I'd build a suit with the ability to fly, like Iron man, which before you say anything not technically a super power so it is allowed!' Beckett laughed.

'I'm surprised you haven't looked into to that already!' She joked. Before Castle had a chance to respond the ornate doors began to creak open. The sound startled them after quiet of their tranquil settings. Beckett jumped to her feet ready to defend him and Castle followed her lead.

'Castle, Beckett?' The Doctor's voice called out. 'Are you in there?'

'We're here.' They said again in synchronized speech. They heard the laugh of the man from earlier.

'I was right, you definitely practice that.' Jack said. The Doctor stepped in with a stern look.

'What did I tell you about wandering off, you could have been lost in here for ages!' Castle was about to apologize but the Doctor grinned. 'No one ever listens!' he said. 'But next time maybe?' he asked rhetorically to which he got a reluctant nod from both of them. Just behind the Doctor, Captain Jack entered, walking over to where the three of them stood.

'Captain Jack Harkness, at your service!' he saluted.

'Jack.' The Doctor warned but Jack just winked at them. 'Right then back to the console room the lot of you.' The Doctor ordered. As he was leaving the Doctor whispered to the TARDIS. 'What were you doing?' he of course had noticed the change in layout. 'Why were you bringing them here?'


Author's note: Sorry it has been so long but like I said there were things and a rhino and Doctor Who recently just... I WAS NOT EXPECTING THIS! ANY OF THIS! Okay, sorry but he's leaving and the Name of The Doctor and the 50th anniversary and just all of it!
