In the console room Alexia held on tight to the the jumpseat as she watched both Doctors working around the console. They were trying to prevent a space cruise liner from crashing onto the planet below. The same space cruise liner that had Amy and Rory onboard.

Earlier, she was quite happily berating John for having one thing continuously on his mind and stupidly asking 'if she was okay', until he suddenly reacted to something and pulled out his Psychic Paper from his jeans pocket. He read it and seconds later was on his feet shouting for the Doctor, who'd been standing just outside the room, listening in. He too had gotten the message as well and they raced off to the console room with Alexia following them.

Now the turbulence they were currently experiencing while trying to keep the space cruise liner on a steady course was making her stomach feel like they were in a tumble dryer.

"What the hell is going on with this planet below?" The Doctor wondered aloud. "There's a thick fog covering the entire planet. About 95% of it."

"If it's just a fog then why is it causing a spaceship to crash?" John asked as he manned the Helmic regulator.

Alexia watched as the Doctor typed something into the monitor and stared at the results the TARDIS gave him.

"What? No way!" The Time Lord uttered, taking a surprised step back from the monitor. "It's not just fog, but smog!" He looked up with a frown and rubbed the back of his neck. "It's coming from the planet below. It's artificial and it seems to be filled with ice crystals. The TARDIS is registering small electrical charges from the smog. It's why we're being jostled about a bit." He returned back to the monitor and did a further scan of the environment.

"Any idea what's causing it?" John asked as he tried to peer round the monitor to get a look at what the Doctor was seeing.

"No idea," the Doctor replied. "But we'll soon find out once we get this ship stabilised."

Alexia wanted to correct him that it wasn't smog or fog, but a Cloudbelt. It was one of the few things she remembered about the episode 'A Christmas Carol'. Not to mention the Sky Sharks. She was about to open her mouth and tell him this when Rose, Jenny and Jaime came rushing into the console room.

"What's the trouble, Doctor?" Rose asked, her eyes wide. "And why is the TARDIS feeling so rocky right now?"

"Because we're using the TARDIS to keep the cruise ship from crashing." The Doctor explained. "But we can't do this for long as it's putting great strain on her." As he said this he adjusted a couple of switches near the monitor.

"So we need to get down to the planet and find out what's causing it." J.D spoke next as he reached over to push a few buttons on the other side of the console.

"Oh, that's easy!" Jenny spoke up. "The one who's causing the trouble. He's called Kazran Sardick and he's got this machine…"

"It's called a Cloudbelt," Alexia interrupted. "That's what he calls it."

Jaime groaned and turned to her mum and Jenny. "Shut up, the both of you!" She practically had to shout and felt surprise from the both of them. "There is something you need to know," Jaime continued. "When it comes to episodes we cannae outright tell them what's goin' to happen. They need to work it out for themselves. Not to mention it could cause lots of problems." She could still feel that her mum was surprised.

"Really?" Alexia spoke up and then turned her attention to the Doctors and Rose. "And you're actually happy to do this?" She asked them. "To not want to know what we know?"

The Doctor nodded his head. "Sometimes foreknowledge is a good thing. But in this case it's not. I'd rather not know about my future or any of our futures. I told Jaime the same thing the first time I brought her onto the TARDIS."

Jaime smiled at the memory but looked thoughtful. That moment felt so long ago now it was a wonder she could still remember it.

"Okay, if that's what you want, then I'll go with it." Alexia reluctantly agreed and Jaime could feel that her mum was puzzled.

"I understand." A clearly admonished Jenny said, her head bowed.

"There is one thing I can tell them," Jaime continued. "And that's tellin' them how dangerous this adventure will be…which is not all that dangerous…well, jus' a wee bit."

With a scowl on her face, Alexia folded her arms and looked at her daughter. "Now why would you tell them something like that?" She asked.

The Doctor was quick to speak up. "That was my idea," he told Alexia. "After a bad experience on Midnight I suggested she could give me a scale of how dangerous it would be."

Shock washed off Alexia and her eyes widened. "No! Tell me you didn't take my daughter to that fucked up planet?! She asked and the Doctor looked somewhat guilty at her reaction.

"I was on the Crusader with him," Jaime told her. "It was the scariest thing that's ever happened to me."

A growl emitted from Alexia and she moved towards the Doctor in a threatening way. So much so that the wide-eyed Time Lord pulled Rose in front of him as protection.

"Calm down ma," Jaime stopped her mother from getting anywhere near the Doctor. "Though it was a wee bit scary at the time the humans didnae get a chance to gan anywhere near the Doctor. I saw to that…and taught them a lesson!"

Hearing this, Alexia stopped and looked at her daughter. Her dark eyes had taken on a chilling coldness that led her to believe she would have done anything to protect the Doctor, her father.

"Oh, well. You've already told us who this Kazran fella is," J.D spoke up. "You may as well finish what you started."

Looking over at the Doctor, Alexia was a little worried he wouldn't allow it, considering his rules, but to her surprise he nodded his consent.

"Okay," Jaime spoke. "The planet is a colony planet for humans and the most powerful man on that planet is Kazran Sardick. He inherited everythin' from his father, Elliot Sardick. That's includin' a machine tha' controls the Cloudbelt. The town appears to be governed by Kazran as its named after his family name." Jaime finished.

"The planet is also named after Sardick." Jenny added, surprising Jaime.

"Really?" She asked her sister. "Why didnae I see that?" Seconds later her eyes widened and she let out a gasp when it came to her. "Och, you're right!" She uttered, looking at Jenny with a grin. Then they started comparing notes on the planet.

Alexia smiled at this with a shake of her head. "There's something else you need to know," she spoke up. "The planet has Sky Sharks flying through the cloud and fog."

"What?" The Doctor's eyes were wide with fascination. "Actual flying sharks?" Now he really wanted to go down to the planet to check out the flying sharks. Except he had to keep cruise liner from crashing.

"Aye, and not tae mention they're dangerous." Jaime spoke up.

"But the ice crystals in the fog harmonises and calms the sharks down. They like music." Jenny added.

"Sharks that like music?" Rose asked, sounding like she didn't quite believe it. She'd seen a lot of things on her travels, but never flying sharks that liked music. She couldn't wait to get down to the planet.

"Yes, well we need to get down to the planet somehow!" The Doctor spoke up. "Because landing the TARDIS is out of the question at the moment."

A big grin appeared on Jaime's face. "That's okay, I can jus' teleport down." Before anyone could protest this she added: "Who wants to come with me?"

"Me!" Jenny jumped at the chance at getting to see another planet so soon after visiting Earth, twice.

"I'll come too!" J.D spoke up, abandoning the Regulator to stand beside Jaime. The Scots-girl looked at Rose and her mum but it looked like they were staying with The Doctor.

"Right, if you're going down, remember to take the surveillance glasses with you." The Doctor suggested, pulling the dark red glasses from a chubby hole on the TARDIS console and giving them to John. The Half-Time Lord put them on.

A grin appeared on Jaime's face. "Let's gan already!" She took a hold of Jenny and J.D's hands and teleported out of the TARDIS.

Alexia looked on, amazed, at the empty space her daughter had been standing on.

Rose had taken control of the Helmic Regulator but a grimace had appeared on her face as she wiped her hand on her trousers. "Why is the Regulator all sticky?" She asked.

The Doctor winced and looked away.

"Probably best not to think about it!" Alexia said and moved to stand next to the Doctor. "Do you need any extra help?" She asked him, noticing and ignoring Rose scowling at her.

Jaime, Jenny and J.D re-appeared inside a rather spacious room with a fire. Unfortunately it wasn't burning so that left the room very cold. They weren't the only ones in the room as there appeared to be a grumpy old man, a family and old grumpy's servants aswell.

"Blimey! Talk about gloomy!" The Doctor was faintly heard through the glasses.

"You can say that again!" John muttered.

"It feels like the 44th Century." Jenny uttered and Jaime looked at her with a grin. "It also appears to be Christmas on this planet." She said.

"And you've already been spotted!" They heard The Doctor state.

They really had. It was the boy who had spotted them first, considering they had appeared out of thin air. The boy had gasped, which had caught the old grump's attention and he turned around to look at them. "Who the hell are you?" He demanded, surprise and anger washing off him. "Where did you come from?"

John was about to reply until Jaime bounded towards the grumpy fella. "Hello, my name is The Omni," she introduced, staring at him with a grin. "This is The Infinite…" She pointed over at Jenny.

"The what?" The Doctor and J.D said, the Half-Time Lord looking over at his niece.

"…and this man there is The Doctor." Jaime pointed at John. "And we have got a wee bit of a problem."

The old grump scowled. "Oh, you do, do you?" He said. "Then maybe you should join the queue like the rest of them!" He turned away from her but Jaime moved so quickly she was standing in front of him within seconds. This time the grump actually looked surprised.

"Not so fast, Mr!" The Omni uttered. "There is a cruise liner above this planet that will crash if you don't turn off your machine."

The grump snorted. "Not you too! It can crash for all I care. Out of my way!" And he pushed Jaime aside and walked away. "Get rid of these people!" He told his Servants about Jaime, John, Jenny and the Pettigrew family.

"Your Servants can stand down," The Omni commanded before they could even move. "In fact they can leave this room." She further commanded and the grump watched in dismay as his servants left the room.

"Where are you going?" He shouted. "Come back here!" They didn't listen to him. The grump turned to her with a scowl. "How did you do that?" He demanded. "They're taught to only take orders from me!"

"You will listen to us," Jaime told the grump, ignoring his question. "You will bring that ship down safely."

The old grump became angry. "No, I won't!" He said in a petulant way and stomped over to his seat by the fire and sat down.

"What about us?" A member of the Pettigrew family spoke up. "Do you want us to leave too?" They were confused so Jaime went over to speak to them.

Meanwhile, J.D and Jenny had gone exploring around the room.

"So, 'Doctor', what do you think?" The Doctor asked his brother.

John frowned. "What do I think of what exactly?" He asked.

"Of Jaime taking charge of course!" The Doctor replied.

Looking over at Jaime, J.D could see she was talking to the boy and even performing 'magic' tricks for him.

"How well do you think she did?" The Doctor further questioned.

"I wasn't aware we were grading her." The Half-Time Lord heard Alexia say to the Doctor.

"I'm not!" The Time Lord replied. "It's just that she and Jenny are the only ones down there who know what's going on."

John grunted, smirking a little. "Well all I can say is she's doing a pretty good job at being us. I love it when she takes charge, kinda makes me go ha…"

"That's enough of that you." Alexia was heard to interrupt. "I'd rather not know."

"Yes, ma'am!" John muttered and started looking around the big room.

"What's that?" The Doctor spoke up when he saw the strange looking device on the monitor. "Is that a Cryochamber?"

"Yeah." John replied and walked over to it, peering into the glass window at the frozen blonde woman. "Pretty woman," J.D said out loud. "Who is she?" He asked.

"She's none of your business." The grumpy fella snapped from where he was sat. "And she is nobody of importance."

Looking over at the grump, John blinked several times, surprised by his arrogance. "Really?" In all my 900 years of travelling through time and space I've never met someone who wasn't important before." He said in a completely Donna-sarcastic way. "So, I'll ask you again…who is she?" He demanded.

"She's a member of this family," The Omni spoke up, standing next to the humans. "Her name is Abigail Pettigrew."

The woman stepped forward, still somewhat amazed by these strangers turning up. "We wanted her to join us for the Crystal Feast." She said.

"That's their version of Christmas on this planet." Jaime explained to John when she felt his confusion.

"…Except Sir won't allow her home. And I miss my sister."

A growl of annoyance came from the grump who was now standing again. "And they don't have 4,000 Gideons so they can't have her. She is mine until they can pay up."

"Gideons?" J.D uttered and quickly understood it was this planets currency. "It's always down to money isn't it!" The Half-Time Lord was obviously quite disgusted. He suddenly felt a flash of anger from Jaime and before he could react, Jaime had the grump pinned against the wall with her face close to his.

"You don't own her, nobody should own another person!" Jaime snarled, her eyes darker than normal and a faint crackle of static electricity could be heard. "By the time I'm finished with you, you'll be doing what you're told!" She had hoped she would have scared him but he just stared back at her defiantly.

"Omni, we're not here to be violent!" John called to her only because The Doctor hadn't liked it along with Alexia. "Let him go!"

With a disgusted expression on her face, Jaime shoved the grump away and walked off, taking deep calming breaths. Meanwhile, Jenny had found Sardick's weather controlling machine. She pressed several buttons but nothing happened.

"Get away from that machine little girl!" The grump spoke when he saw Jenny hanging around the machine. "Only I can work it."

But Jenny ignored him as she continued to press buttons. "They really do have isomorphic controls!" Jenny stated, looking over at Jaime and J.D.

The grump, who was about to storm over to the machine, stopped suddenly, eyes narrowed. "How did you know that?" He asked.

"We know a lot of things," Jenny said to him. "Just how we know your name is Kazran Sardick, Son of Elliot Sardick."

His eyes widened and Jaime smiled when she felt his fear.

"How do you know that?" He asked. "You're not local so how can you possibly know about that, about me?"

Now they had the advantage. "That doesnae matter right now," Jaime said and walked over to the machine. "But I think I can do somethin' 'bout this." She was about to put her hands on the machine when Jenny stopped her.

"Whatever you're going to do next, just think. What if it causes worse problems, like the Sharks attacking?" She worried.

Jaime looked at her sister. "Then we'll use Abigail to calm the sharks." She replied but could still feel that Jenny was worried. The Omni turned to her. "Can ye sense the Timelines?" She asked and Jenny nodded. "Can you tell if it's fixed or in flux?" Jaime asked next.

Jenny concentrated and after awhile she spoke up. "It's in flux." She said.

Jaime nodded. "Then in that case I know what I'm doin'. And I really dinnae want to go through the bother of changin' his whole timeline, only for him to be locked out of the machine and unable to use it." She hissed out so that only Jenny and John could hear her.

"Do whatever you think might be best." The Half-Time Lord told her and the Doctor was heard to agree.

With a nod, The Omni turned back to the machine, put her hands on it and concentrated. Seconds later it sparked and died and Jaime stepped away from it.

Kazran's eyes widened. "NO! What have you done to it?" He cried out and tried to get it working again by pressing numerous buttons. Nothing happened. It remained broken.

"EMP blast, Mr Sardick." Jaime said and turned to John. "How's the flight up there?" She asked.

"Becoming less like a rickety bus and more like an electric car." They heard Alexia utter.

"Be able to disengage soon." The Doctor said.

A very angry Sardick turned to the Time Travellers. "You fool! You menace!" He shouted specifically at Jaime. "I don't know what or who you are but you're causing untold damage to this world. Without the Cloudbelt the sharks will only intensify their attacks!" He didn't know what he'd expected but he certainly didn't expect the strange female to be grinning. "What are you smirking at?" Kazran snapped at her.

"Not to worry, we can use Abigail," The Omni said, turning towards the Cryochamber. "I've heard she's an amazin' singer."

Abigail's sister gasped. "It's true, Sir," she said. "She often sung me to sleep when we were younger. It always made me feel safe and happy."

Kazran heard this and scowled. "Bah, humbug," he muttered, ignoring the giggling from the off-worlders. "I will not be unfreezing her."

"Well that's tough, because we'll be doin' this or without your help!" Jaime snapped back at him.

"What about an amplifier!" Jenny asked. "Wouldn't we need to use a Sonic Screwdriver?"

Thinking about this, Jaime remembered that a broken Screwdriver was used to help amplify Abigail's voice. "Somehow I dinnae think breakin' any of our Screwdrivers would help us much."

"What?" John and The Doctor exclaimed.

"However I do have an idea!" Jaime continued and concentrated once again. A black shiny pen appeared in her hands and she held it up with a grin.

Jenny recognised it. "Wait, is that…"

"No way, you have got to be kidding me!" J.D exclaimed, his eyes wide and amazement washing off him. "That's Miss Foster's Sonic Pen."

"I often wondered where that went," The Doctor was heard to say. "I went to toss that in the bin but it disappeared even before it got there. Now I know. It was Remote Teleported through Time and Space."

Jaime continued to grin. "Well then, let's get started!" She uttered.

Once they had attached one half of the Sonic pen to the transmitter beam, the other half was then given to the now unfrozen Abigail Pettigrew and she was told to sing her heart out to calm the sharks. And she did, once they all went outside into the beautiful clear skies of Sardicktown, Planet Sardick. The singing attracted everyone who was previously afraid to go out. It even started snowing and it prompted Jaime and Jenny to attempt to build snowmen.

When the space cruise liner was finally able to fly on its own, they were joined by Alexia, Rose and the Doctor with the TARDIS. When Rose had looked at Abigail she had commented that the woman looked like Katharine Jenkins, much to Jaime, Alexia and Jenny's surprise. So the Doctor investigated further and it turned out that Ms Jenkins was a distant relative. He put down Abigail's familiarity to a case of genetic spacial multiplicity.

Appearing thoughtful, Alexia asked the Doctor if the same thing happened with Jago and Colonel Hugh Curbishly. And also with Martha and her Cousin, Adeola.

Jaime called Rose over to help her and Jenny build a snowman. While continuing to build the snowman, Jaime noticed that Rose kept looking over at Alexia and The Doctor, who was still talking to her mum in a very animated way. Jenny was grimacing at the blonde because the feelings she could see were dark and moody as ever. So The Omni gave her a nod and Jenny went off to see what her uncle was up to.

"You know, jealousy really doesn't suit you, Rose!" Jaime spoke up.

Rose turned to her, eyes wide. "What? No I'm not…" She halted when Jaime gave her a withering look. "Okay, maybe I am a little…" Rose admitted sheepishly. "But only because she's so close to the Doctor." She looked back at Alexia and The Doctor. "She's always around him. It's like she wants to get into his pants."

Somehow managing to keep her patience and stopping herself from doing something drastic, Jaime sighed and shook her head. "I doubt my ma' has any interest in The Doctor," she replied, noticing Rose wince. "They're jus' two adults havin' a chat together." And she would know if something was going on between the two.

Rose looked at her again, her brown eyes dark and moody. "But I'm an adult, too! Why isn't he talking to me?" She whined.

"Are you sure 'bout that, Rose?" The Omni asked. "The way you're actin' seems more childish than adult. And this jealousy of yours really does take the biscuit." Without another word Jaime walked away from the snowman. Her hands were cold from playing with the snow, but thankfully she knew just where to put them.

Rose scowled angrily at the half finished snowman, ignoring the yelp of surprise from J.D. She really couldn't help getting a case of the green eyed monster. She'd always been like that since her early teens. And not once had she been called out on it! Her thoughts continued and her anger continued to rise until she struck out at the snowman's head with a grunt and it tumbled to the ground, smashing to bits.

"Hey now! What did that snowman ever do to you?" A familiar voice asked and Rose turned to The Doctor who had joined her. She just smiled awkwardly and shrugged her shoulders, feeling a tad embarrassed. "Are you okay?" The Doctor then asked because he'd sensed a flash of anger from her for some reason.

"Yeah, sure, I'm fine." Rose muttered a reply before turning away from him and wiping her eyes.

The Doctor furrowed his brows. "Are you sure?" He asked, worried now and wondering why she was crying.

"Yeah, it's just Abigail's singing, that's all." Rose made an excuse.

"Oh, right." The Doctor smiled sheepishly and rubbed the back of his neck. "It is rather sobering is it!" He said, even though he didn't believe it was the song that was making her cry.

Rose nodded and smiled faintly when the Doctor put his arm around her shoulders and pulled her closer to him in order to comfort her. Rose was about to say something to the Doctor, that was until she was interrupted by Amy and Rory turning up.

"Doctor!" The ginger Scot shouted and the couple looked up as they arrived.

"What are you wearing?" The Time Lord asked.

Amy was wearing a police uniform but it wasn't as skimpy as it had previously been. Meanwhile Rory appeared to be wearing the armour of a Roman Centurion, dragging their suitcases along behind him.

"There was a fancy dress party onboard," Amy explained. "Then all hell broke loose when we got trapped in that Cloudbelt."

With a wide-eyed expression the Doctor nodded as he listened.

Meanwhile J.D, Jaime, Jenny and Alexia, who had an arm around Jenny's shoulders, watched, along with Abigail's family, in astonishment as a singing Abigail gently caressed a shark that had come down to investigate. Alexia thought it was a very weird looking shark. It didn't look like anything she'd seen on the episode. Instead of the usual grey-blue, it was more dark green-blue with yellow spots. And she was sure it's eyes were purple.

"That is the most beautiful thing I've ever seen!" Jaime was heard to say and Alexia looked over at her. She noticed her dark eyes looked bright.

"Oh no, you're not keeping a flying shark as a pet!" Alexia warned her older daughter.

Jaime looked at her mum and opened her mouth to say something, but Alexia's expression made her stop. Instead, her face blushed and she looked away, truly told off. Jenny giggled.

"I've never seen the sky so clear!" Alexia heard a voice say in wonderment and looked over at Kazran Sardick. He was stood in the middle of the road, looking at the night sky, so Alexia cautiously joined him. After all, he might not like the company considering his timeline wasn't changed.

"Beautiful, isn't it," she said to the grumpy man. "To be able to see the stars without the lights polluting the sky or a never-ending fog, or even a horrible smog."

Sardick looked at her, scowling. "Who are you?" He sneered. "You're not from around here are you?" He could see that was obvious with the type of clothes she wore. They were Old World clothes.

"No, I'm not. It was my daughter who spoke to you earlier."

"Oh, so you're the mother of that weird little freak!?" Sardick growled out angrily. "That thing damaged my machine. I'll never get it working again." He was proud to say he had managed to knock the smile off the woman's face.

At first she was shocked over what he just said about Jaime, then she was angry. A loud crack resonated around the street as Alexia slapped Sardick hard enough for him to tumble to the ground. He seemed to curl up as if expecting more. "You're a terrible human being, Kazran Sardick," she shouted as she stood over him, aware that everyone was watching them. "No wonder nobody likes you!" His eyes wide, the old grump stared up at her, a hand on his reddening cheek. "As for that machine of yours, it was a menace to society!" Alexia continued angrily.

"Mother!" Jaime called and pulled her mum away from the old grump. "Come away from him, he's not worth the bother."

"Yes, but you should have heard what he said about you. I was only defend…"

"I really dinnae care what he was sayin'," Jaime interrupted, glaring at her. "I've heard worse before."

Alexia sighed, shrugged her shoulders and rubbed her aching hand. She had slapped Sardick so hard she felt she might have sprained her wrist, but it felt so good to have wiped that nasty look off his face.

At this point, Abigail's song had finished and everyone watched, astonished, as she walked over to Sardick and held her hand out for him. He seemed hesitant until she spoke to him, so he reached out and took her hand. She pulled him back to his feet and continued talking to him, even waved her family over.

"I think we ought to go." The Doctor was heard to say and Alexia nodded in agreement. The Time Travelling troupe headed for the TARDIS.
