"Finally, everyone has arrived and you can all make yourselves comfortable while you prepare to meet your doom!" Strax announced.

"What did he just say?" Rory asked.

"Where's the girl?" River asked, looking concerned.

"She is fine. Just resting. She appears to have had some kind of vision, but she refuses to tell us the exact details. Only that we need to rescue Miss Murphy immediately on two separate occasions in time." Vastra explained.

Pandora rushed into the atrium of the large Victorian house, her eyes grew wide at the sight of the TARDIS as if the she hadn't seen it in so long.

She frowned and bit her lip. "D...dad...?" She asked a little shakily.

The Doctor stepped out of the TARDIS. He could feel everyone's eyes on him judging whether or not Pandora was finally safe.

He tried to think of something to say but before he could even open his mouth Pandora rushed forward and hugged him so hard she almost knocked him over.

"Oof..." he awkwardly put his hands on her shoulders, but it only made her squeeze tighter.

"That's a change..." Amy muttered to Rory who looked on in shock.

"So is she trying to kill him...?" He whispered back.

Pandora finally let go and looked up at him. There were tears in her eyes.

He wasn't sure how he knew, but he did. Whatever she'd seen was terrible, more than terrible. Her eyes seemed older than they did before, she'd seen something truly awful.

"We have to save mum..." she said, "You and me..."

"Of course... where did they take her?"

"No, I mean in the future... we have to go... as soon as you get back."

The familiar sound of the TARDIS landing filled the room and The Eleventh Doctor opened the doors. He swung his arms open as if to state his arrival, but before he could Pandora rushed through and started frantically setting the console.

"Okay, never mind." He shrugged.

"You'll find her at those coordinates." She said rushing out dragging Jack behind her.

"Wait, what are we doing?" River asked, sharing a concerned look with Amy.

"We're rescuing McKenzie. While Pandora... Also rescues McKenzie... But in the future..." The Doctor announced, as if the plan was completely fool-proof and everyone understood immediately what they had to do.

Pandora grabbed the other Doctor and dragged him to his TARDIS.

"No time to explain, we have to go." She said.

"Okay, but–" He begged.

"Look we have to get to her now... But you have to promise when you get back that you won't tell her anything. Okay? You have to trust me."

The Doctor shared a concerned look with Jack, he shrugged in return.

He didn't know what to say, she could be telling the truth, or luring him into a trap. He had no real way of telling, but something in her eyes made him believe her.

"Okay. I trust you." He said.

Her face almost twitched into a smile, before she set to the console. He closed the doors behind him.

"Right all we need to do is be here at the right time..." she mumbled to herself.

Eleven, his crew and Jack watched as the TARDIS disappeared before their eyes.

"Come on gang, we have a damsel to rescue!" The Doctor announced.

"I wonder if we'll ever find out what happened to them...?" Rory asked looking over to the spot where the older TARDIS had vanished from.

"Right then! Jack will you be accompanying us?" The Doctor asked.

"If it's alright with you I need to speak with the Captain…" Vastra replied.

Jack shrugged at The Doctor, "You heard the lady."

The Doctor, frowned. "Well, come along the rest of you!" he announced, "Time to leave." He quickly grabbed his companions and pulled them into the TARDIS, "Rescue mission! Come on, let's see a little more hustle!"

"But Doctor, we have no idea what we're doing!" Amy shouted.

"Just remember glasses man is bad! We can't let him see McKenzie escaping."

"Got it, but you still haven't explained–!"

"Right." The Doctor flew the TARDIS with River's assistance, "What I need you to do, what we need to do is get onto that base, 350 years or so before we landed before. Because the McKenzie we met is on that base right now captured by that man with the glasses."

"Okay..." Rory frowned, "But isn't that crossing your own time line? If you're there in the future?"

"Well, no, not really as it's all happening right now. Their fight, our rescue, whatever got them there in the first place... All happening now, just at different times!"

"Timey whimey–" Amy cringed as she remembered how McKenzie had laughed at her for saying that, but couldn't help returning The Doctor's infectious smile.

"But in all seriousness, this is extremely dangerous... we don't want them getting their hands on my TARDIS–"

"Or any other versions of you, Doctor..." River frowned.

"Yes, dear."

"You have to stay here. We don't want them to find out about another regeneration of you. Who knows how that could upset your future."

"Ah, you're right." He threw his hands up in the air as they landed inside the base, "Stay safe you three... I can't believe I'm letting you go off by yourselves..."

"It's important. We can handle ourselves."

"Can we?" Rory asked.

River sighed and grinned, "Let's go."

The crew made their way through the familiar halls, keeping on their toes for any signs of danger and looking out for clues to McKenzie's whereabouts.

Signs started showing up directing them to a medbay. They must have been in a different section than before.

"She could be in there?" Rory asked.

"Could be, but I'm more interested in seeing the old lab in action..." River replied.

"But what about McKenzie?" Amy asked.

"Oh I'm pretty sure The Doctor left to rescue her about thirty seconds after we left? So I'm sure she'll be fine."

River moved quickly through the white panelled corridors wishing she had swiped The Doctor's psychic paper. But then she remembered she had his old sonic if she needed it. She smiled to herself.

The lab wasn't far from here as she turned the last few corners. The doors she had busted open were just ahead, she held the sonic screwdriver out and pressed the button, opening the doors.

"Have a pleasant visit, Dr Song." She heard a woman's voice say.

River turned to the small check point and just caught a glimpse of a redheaded woman with glowing golden eyes disappearing into thin air.

River frowned, but realised the security had cleared herself, Amy and Rory as visiting staff from another base.

She grinned and headed through to the lab.

Amy and Rory carefully wandered through the base. Having the knowledge that The Doctor had already gone after McKenzie, they were unsure of what exactly they were supposed to doing.

A small man in a blue uniform quickly ran up to them from behind a corner. He seemed out of breath.

Amy and Rory froze. But they recognised him as the person recording video diaries.

"Ma'am, Sir... I cannot apologise enough, we were told about your visit but the time must have been wrong on our information." He wheezed a little.

"Of course. That's fine." Amy snapped, "Just see that it doesn't happen again."

Rory glared at her and she shrugged back.

"If you would like to follow me to head office we can properly start the tour. I assume Dr Song is already at the lab?" He asked as they began to walk further along the corridor.

"Yes, if that's where she usually is." Rory replied.

Amy nudged him in the side and gave him a scolding look.

They came to a lift on the side of the base. It was right on the edge and view was incredibly foreboding. The same large planet below was only just the beginnings of a storm, a few swirls here and there. But it was possible they didn't even expect a storm or more likely that no one on the base would see it in their life-time.

Amy and Rory followed the frightened looking employee as he led them through a new part of the base. It was much more decorated with silver furnishings and even potted plants. Whoever was in charge really cared about showing that they were in charge. It felt homely in a very strange way. The kind of someone is definitely watching you kind of way.

"Right this way. He's been expecting you." He said.

"Ah, right yes. Of course." Amy replied.

The door opened to a large office, computer screens lined one side of the wall with a small console in the middle, the screens showed all the different rooms and labs of the base. On the opposite side was a large window looking out at another astonishing view of the gas giant that was Orion.

"You may go, Preston." A voice said.

Amy and Rory realised there was someone sat at the large desk opposite them, He was looking out at the planet below.

"Yes, sir. Thank you, sir. Would you like me to bring Dr Song for you, sir?"

"Yes, Preston."

"Of course, sir. Sorry again… sir."

Preston backed out of the room and the door closed behind him. The man in the chair turned to face them and he stood up. He wasn't tall, not as they would have expected. He gave off the impression of someone who should be taller. He was wearing thick rimmed glasses.

Amy could tell Rory was trying to tell her to be careful. She quickly shot him a glare telling him she understood. The exact thing they had been told to avoid at all costs and they were currently stood, or rather trapped in his office with him.

"First things first I would like to apologise for my assistant's incompetence." He said.

"That's fine… I know how assistants can be." Amy mumbled.

"No matter, I'm sure everything is in top shape regardless?" Rory chimed in.

"I'm sorry?" Wade seemed a little shocked.

"Well, why should your facility only be in peak condition when you're expecting visitors?"

Amy offered him a look of approval as Wade was struggling to keep his authority.

"Yes, of course. I apologise. We keep everything at an exceptional level of upkeep. I'm sure you'll be impressed." He shuffled uncomfortably.

"Glad to hear it." Rory nodded.

Wade headed over to the door to open it, but before he had a chance, someone on the other side had already done it. It was Preston again, this time he was out of breath.

"Preston, what is it now? Where's Doctor Song?"

Preston's eyes grew wide, "Sir, we have a situation… in the lab…"

Wade's face suddenly changed, "Has it happened again?" there was a new urgency to his voice.

"Yes. We need your attention right away."

"Yes of course," He turned to Amy and Rory, "I must apologise but I need to see to this. Please stay in my office… and help yourself to the minibar."

Wade and Preston ran off, leaving them inside his office.

"Well, that's not going to look good on their report." Rory sighed, grinning at Amy.

"Where on Earth did that come from?" Amy grinned, jumping up onto the edge of the desk, "Mr Authority…" she winked.

Rory shrugged, "We had this visiting Doctor, back at the hospital… always very strict."

"Well, well, well… If this were my office…" she grinned, miming pushing everything off of the desk.

Rory couldn't help but blush. "Amy, shouldn't we be snooping or something? We must be able to find something useful on these cameras… they must show the whole base!"

"Probably," she pouted, "We'll probably be able to find McKenzie."

Rory looked over the many screens, using the console to flick between them to get a better look. There weren't as many people working here as they would have thought, but they seemed to just be working on simple projects, as The Doctor had said when they arrived here.

"Do you think any of these people have any idea what their boss is getting up to?" Amy asked, looking through things on Wade's desk.

"I doubt it…" Rory said, "Hey, look! There she is!"

"Guess they are keeping her in some kind of hospital room."

"Looks like, who knows what they've been doing to her…" he shuddered.

An alarm sounded around the base making them jump, McKenzie looked up from her bed and Amy noticed River on the cameras.

"I didn't do anything!" Rory backed away from the console.

"I don't think it was you…" Amy pointed to the perfectly framed image of River pointing a gun at someone.
