Hydra's are a water based shapeshifting humanoid working for the Trickster and made an appearence in the story 'Brilliant and Brave'.

Meanwhile, the Half-Time Lord continued to protest as he was pulled along the corridor by Jaime. He could sense she was aroused…and to be honest he was just as aroused as she was, despite his need to rub one off being constantly on his Mind. And the fact he remained aroused seconds after really quite puzzled and annoyed him. He just couldn't get it off his Mind.

"What are you going to do?" J.D asked his bond-mate.

"I'm goin' tae give you a good long fuckin'," Jaime replied, looking back at him with a predatory grin. "Or maybe I'll tease you tae the edge of madness."

Eyes widening, J.D gulped but continued to allow Jaime to pull him along. What she had just said made him ridiculously aroused and so hard he felt as if he was about to burst out of his underwear. Good thing he was wearing baggy jeans or he'd really be uncomfortable!

Unexpectedly, the corridor lurched and the couple tumbled to the right, causing them to fall against the wall.

"Blimey!" John groaned with a wince. "Somebody taking the TARDIS for a ride?" He wondered out loud.

A growl came from Jaime and she stepped away from the wall. She'd slammed against it pretty hard, hurting her back just a bit. Then she frowned thoughtfully. "That would be Rose," she replied. "Flyin' like a professional."

J.D looked surprised as he too stepped away from the wall.

"Just how long have we been gone…for them at least?!" Jaime asked the Half-Time Lord, turning her attention to him.

"Welllll…" J.D stretched out, running his hand through his messy brown hair. He was actually quite surprised with Rose's ability to fly the TARDIS without the Doctor's help. She must have put in a lot of time in order to know how to pilot the Old Girl correctly. Normally it would take hundreds of years to learn to pilot a TARDIS. And that's even if they pass the test. Rose had apparently learned all that in just a couple of…

"Jaime! J.D!" An excited voice cried out, cutting through his thoughts. "You've returned!"

Jaime turned her attention towards her sister, who was running down the corridor with an excited expression on her face. "Hello Jenny, we've only just got back." She replied to the young Time Lady and was gathered up in a hug by her sister.

"Oh, Rassilon, it's been too long. Far too long." Jenny said, grinning happily. Then once she'd hugged Jaime, she went on to hug her uncle.

"Hello to you too!" A blushing J.D answered back as he returned the hug while being careful not to let her know how erect he was.

Meanwhile, Jaime was frowning, worrying over just how long they'd been gone for everyone else. First there was Rose, even if she didn't even say it, then John, and now Jenny. And why was her sister feeling worried even though she looked happy? Rose was just the same. "What's on your Mind, Jenny?" She asked her sister.

Jenny let go of the Half-Time Lord and turned towards Jaime. "I need to talk to you." She said to them but mostly to the Scots-girl. "It's urgent!" She added, grabbed Jaime's hand and dragged her back along the corridor.

John was about to follow them when a familiar door materialised in the wall next to him. He looked at it with a chuckle. "Oh, you know me so well, Old Girl!" He said. Grinning, he opened the door and walked into the bedroom he used when not in use by The Doctor. "Looks like it's just me and my hand." He said, shutting the door after him.

Jaime let Jenny pull her along the corridor until they came upon a door. Then Jenny pushed the door open and they walked into the room. Or rather, the garage. There were several vehicles in it that hadn't seen a road for a long time. There was a white futuristic looking car that could possibly hover or even fly, a 1920's yellow modified Roadster, a peddle bike that had exhaust pipes, an old battered Land-speeder, a yellow School bus, a V-STOL known as a Spinner and an Anti-grav bike.

"What are we doin' in here?" Jaime questioned as she watched Jenny walk towards the Roadster known to The Doctor as 'Bessie'. She smiled fondly at it, remembering the time she and John took it out for a spin around the countryside back in the Seventies. It had been a fun ride out. Well, that was until Torchwood kidnapped them in a case of mistaken identity.

"We need to talk," Jenny said again. "Because it's very serious." She sat in the driver's side of Bessie and started up the car. It chugged into life and the sound of the engine reverberated around the garage.

"Jenny?" A frowning Jaime inquired, jumping into the passenger side seat.

*Its Amy,* Jenny mentally replied, shifting in her seat to face her sister. *She's not herself.*

Jaime smiled faintly over Jenny's use of telepathic chat while the car was running. *How do you mean?* The Scots-girl questioned back in the same way.

*She's been swapped,* came the reply from Jenny. *Remember!*

And she did. She remembered they were in the middle of Series 6, in which Amy was pregnant with Melody, only to be kidnapped by the Silence. *The Flesh!* Jaime realised. *Amy's currently a Flesh duplicate.* Now Jaime realised why they'd been gone so long. *Did you deal with the Silence?* she then asked Jenny. *You would have all been on the run for three months. Is that how long we've been gone?* she questioned.

Jenny shook her head. *Technically it's been five months. But we did spend three of them running from The Silence.*

Jaime sighed and shook her head. She didn't think it would have been THAT long! Five whole months?

*Its been a long time since I was last on my own,* Jenny said with a faint nod. *And it was tough, running about and trying to hide from something I couldn't ever remember.*

Jaime grimaced at that little detail, remembering that they had the ability to make you forget them once you'd turned away. If they could do that to Jenny, who had infinite Psionic abilities, then what chance did herself have with them? *At least you had Canton to help you out.* She said and Jenny smiled, nodding.

*Yeah, he was nice. And kind.* She replied.

Feeling uncomfortable, Jaime shifted in her seat in order to get comfortable again. *What about Dad? Does he know about Amy?* Jaime further questioned her sister and Jenny nodded once more.

*He was beginning to suspect, especially after Amy told him she was pregnant, only to tell him she was wrong afterwards. He told Rose he was going to help me with my Time Lord abilities and took me to the training room and throughout the training he asked me if there was anything strange about Amy.*

Jaime frowned. *And what did you tell him?* she asked, knowing herself, her mum and Jenny couldn't give much away.

A grimace appeared on Jenny's face. *I said there was something not right about Amy, that she was a duplicate. And that I would tell him what kind of duplicate when the right moment came.*

Breathing a sigh of relief, Jaime ran her hands through her hair. No doubt The Doctor had Jenny's complete trust with this. But a frown soon appeared on Jaime's face and she looked back at her sister. *Why didn't Dad want to tell Rose?* she asked, eyes going wide. *She's not a Flesh Duplicate as well is she?*

Jenny shook her head. *No,* she replied. *Rose is definitely Rose. He just didn't want her worrying or acting weird around Amy. Though he suspects Rose might have an inkling she knows something is up with Amy.*

Jaime nodded her head thoughtfully. Was that the reason why Rose had been so worried when they had teleported into the console room? *So are we finished here then?* She asked. *I might have to tell John, get him up to speed.*

*You should,* Jenny replied before looking around in confusion. *Where is John anyway?*

Jaime let out an exasperated sigh, sensing what the Half-Time Lord was doing and feeling his arousal reach new levels as he continued what he was doing. "You really dinnae want tae know!" She spoke out loud for the first time in minutes, and then reached over to the driver's side and turned the engine off. "That's just a waste of fuel." She said and once again frowned in thought. "I once took a ride in Bessie with John. We were in the 70's hangin' out with the Third Doctor and Jo Grant. I didnae know she was even in here!" In fact, where had all the other vehicles come from for that matter? She was pretty sure The Doctor wasn't a collector of cars and transport from movies and TV shows.

"What was that like then?" An excited Jenny asked her sister.

"Thrilling." Came the distracted reply. "Come on, let's see where Rose took us." Jaime scrambled out of the car and Jenny followed along.

"Actually, there's something else." The young Time Lady said and the feeling of sheepishness and guilt washing off Jenny made Jaime turn to her.

"What did you do?" She asked.

Jenny smiled nervously and rubbed the back of her neck. "We went to this planet the other day and in the marketplace there was this booth handing out flyers to a race and some of the natives were signing up." She shifted her stance. "I signed you up."

Jaime felt confused. "Why would you do that?" She asked, especially since they had been jumping through The Doctor's timeline at the time.

"Because it's not a normal race," Jenny replied. "It's a flying race. And it's Super-Sonic."

Jaime's eyes widened. "WHAT?! I can't bloody fly Super-Sonic!"

"I know," Jenny nodded sheepishly. "But we once met a future you who could. You could easily learn how to."

The Scots-girl sighed, thinking. If her future self could fly Super-Sonic, then that meant she was going to need to put in a lot of training to achieve this. "Okay, fine. When is this race?"

"Linearly it was a week's time," Jenny replied and Jaime thought she had the usual seven days. "Only there's four days in a week, but the day is long by thirty-five hours."

Jaime gawped back, stunned. Only four days? "Jenny!" She cried out. "How am I supposed tae learn tae go Super-Sonic in just four days?"

"We're in a Time Machine!" Jenny defended.

"That's not the point!" Jaime argued back. "Bloody hell, I've got tae push myself hard enough, tae train like an absolute lunatic for a flyin' race on some stupid bloody planet I've never been too before!" She growled out before angrily storming out of the garage.

"Wait!" Jenny cried and raced out after her sister.

Back in the Console Room, The Doctor sat on the jumpseat with his feet up on the edge of the Console and his arms on the back of the seat, waiting for Rose and Alexia to return from wherever they had gone off too. He knew the others had returned when Jenny said she sensed Jaime and suddenly ran out of the training room. When he felt the TARDIS enter flight mode he frowned, wondering who could be at the controls. Rose perhaps? Well, that's what the TARDIS was telling him anyway. So he too exited the training room to find out what was going on.

By the time the Time Lord entered the Console Room it was already empty. When he checked the Co-ordinates on the Monitor he saw they had landed in the West Yorkshire village of Skelmanthorpe, in 2015, which was a bit odd. Why would she have landed there? Then when he checked the outside camera he watched as Rose and Alexia walked off down the street, with Alexia giving a quick glance back at the TARDIS.

And now he sat here waiting for them to return while thinking things over. For awhile now he hadn't been able to hear much of Rose's thoughts, yet he could sense she was very worried. And in turn that made The Doctor feel just as worried. Could Rose have found out that Amy wasn't Amy, and that she was unsure how to bring up the subject. And that brought his thoughts to Amy. Amy who had apparently been duplicated at some point during their harrowing adventure in 1969 America.

And now he had even more things to figure out, such as who were The Silence and what kind of duplicate was Amy? She wasn't a Sontaran made Clone as she would have given off a tell-tale smell. Nor did she have any quirky give aways you got with Autons, Zygons or even Rutans. What if she was a Hydra?

Then he remembered Amy telling him she was pregnant, only to backtrack on the idea once that adventure was over. So did that mean the real Amy was still pregnant? And just where exactly in the Universe was she being held? And if Jenny couldn't tell him just yet, then neither could Jaime or Alexia.

Speaking of Jaime, he could sense she was suddenly angry…very angry…and he had a good guess why she was. A short time later he heard their voices before Jaime came storming into the Console Room, followed by a protesting Jenny.

"DAD!" The Scots-girl roared, causing The Doctor to wince at the loudness of her voice. "Have you heard what Jenny's gone and done?" Jaime growled, standing in front of The Doctor with a death glare in her eyes.

"I did it because I knew you'd be interested in a race where you could fly," Jenny defended herself. "Or so I thought!" She rolled her eyes at this.

Standing up, The Doctor looked at his daughters and opened his mouth to speak until Jaime turned to her sister.

"Four days, Jenny," she shouted back. "Four fuckin' days!"

Jenny growled out in frustration. "Yes, there's only four days but the hours are long." She replied. "And we're in a TIME MACHINE!" She followed up with a yell.

Still standing and looking awkward, The Doctor felt he really needed to calm them down. "Firstly, it's brilliant that you, John and Alexia came back. We've really missed you," he said to Jaime who smiled. The Doctor then turned to Jenny. "And secondly, I told you she wouldn't like it."

Jaime's eyes widened for a moment until her anger came back full force. "WHAT?" You actually let her do it?" She blurted out, making The Doctor grimace at her reaction.

"No, I told her she should think about it first," he replied. "Not to sign you up in case you reacted the way you are now. But she signed you up anyway!"

While the Doctor had been talking, a wide-eyed and worried John came hurrying into the Console Room, followed shortly by Amy and Rory. "What's going on?" The Half-Time Lord asked.

The Doctor looked over at his brother and noted the sweaty flushed face, the messy hair and the ruffled clothes, then once he sensed the extreme arousal he knew exactly what John had been doing. He scowled in disgust.

"Looks like Jaime's just found out Jenny entered her into the Super-Sonic Race." Amy spoke up and Jaime glared dangerously at the Scottish ginger.

"The what race?" John asked, looking from the Ponds to everyone else in the room.

"The Super-Sonic Race," The Doctor explained. "It's a flying race. On this planet where natives have the ability to fly using their natural telekinesis."

John frowned, feeling a tad puzzled. "Right…and what's wrong with that?" He asked.

"Because there's only four days 'til the race and I cannae fuckin' fly Super-Sonic!" Jaime snapped at him and John's expression turned awkward looking as he rubbed the back of his neck.

"Oh!" He muttered.

"I signed you up because I had a good feeling about it," Jenny still defended her actions. "You might just win it!"

Unfortunately this brought on a fresh round of heated arguments between the sisters, while both The Doctor and John attempted to calm them down.

Meanwhile, Rose and Alexia had returned to the TARDIS unseen and unheard and were watching the argument unfold. "What the bloody hell is going on?" Alexia wondered.

"Uhh…" Rose groaned. "We were on this planet not too long ago and Jenny felt she needed to sign Jaime up to some flying competition." She answered.

"What?" The woman uttered, puzzled over why Jenny would do something on Jaime's behalf even though they hadn't even been around.

As the arguing continued, she watched Rose trying to get The Doctor's attention. Though Alexia doubted they would get a word out with this racket going on. An idea suddenly came to Mind and she pulled the flyer from her pocket. The Doctor, being a Time Lord, didn't believe in ghosts, but Rose would probably love it.

"Hey, Rose!" She called, catching the blonde's attention. "You two will probably want to go somewhere a little more quieter than this." Alexia stated and handed over the flyer to Rose, who looked at it with a furrowed brow.

"Most Haunted?" Rose then chuckled. "The Doctor will love that! Thanks."

Once Rose was sorted, Alexia turned her attention to the arguing and whistled loudly. It certainly got everyone's attention. "I don't know what's going on here, but I'd like an explanation," Alexia spoke. "Just not here." She followed John, Jaime, Amy, Jenny and Rory as they exited the Console Room.

The Doctor tried to follow but Rose held him back. "Doctor, there's something I need to tell you." She said and immediately felt bouts of worry from the Time Lord. Even his brown eyes took on a sad look. "Don't worry, it's nothing too serious." She quickly added. "But can we go here first?" And she showed him the Most Haunted flyer.

The Doctor snorted, "Ghosts? Rose, there's no such thing!"

"Yeah, I know. But aren't you just a tiny bit curious?" Rose answered him, followed by her Rose Tyler Smile, the one that always melted him.

"Oh, alright!" He sighed, took the flyer off Rose and went to the Console in order to put the co-ordinates in. Rose grinned happily and joined The Doctor at the Console.

In a bid to calm everyone down, Alexia had corralled the fighting sisters, J.D and Amy and Rory into the Media Room. Sparky the Pikachu and Blaize the Growlithe had both been sleeping on the sofa together, but when John, Alexia and Jaime walked in, the two Pokemon were awake and alert.

"Pika pika!" Sparky cried out and jumped from the sofa into Alexia's arms.

"Growle!" Blaize proclaimed happily and barked non-stop while running circles around John and Jaime.

"Hello to you too, Sparky," Alexia spoke and gave the Pikachu's head a good rub. "I've missed you too!" And that surprised her quite a bit, considering she'd never had a pet before.

Maybe this was a good thing. Hearing Blaize's barking tapering off, Alexia looked up to see Jenny, Jaime and John all petting the puppy. And no more arguing. Alexia grinned. This was definitely a good thing. Maybe now she could find out why they were arguing.

"So what's going on here?" Alexia questioned, letting Sparky climb onto her shoulder. "What's with all the arguing?"

It was Rory who answered her first. "Because Jenny signed Jaime up to a race that requires flying."

Alexia sighed at this. "I already know that question from Rose. Why the arguing?"

"'Cause the race is Super-Sonic flight and I cannae fly Super-Sonic. I can fly fast, but not that fast!" Jaime replied.

The woman was puzzled over her daughter's words. "But you can," Alexia told Jaime. "Or at least a future version of you can!" She watched as Jaime let out a frustrated huff and shook her head. "What's gotten you so het up?" Alexia questioned.

"It's just…" She started before halting and deciding to take a seat on the sofa. "It makes me nervous!" She proclaimed.

Amy laughed at this. "You? Nervous?" She said, but Jaime ignored her. This version of Amy's Mind was wide open and she could hear echoing dual thoughts which was really quite off-putting.

"Why would you be nervous?" A curious J.D asked Jaime as he sat next to her.

The Scots-girl rolled her eyes. "Do you really have tae ask?" She snapped at him, grimacing when her mum told her off. "There's comics, books and a TV series based on the Black Bullet, which happens tae be me, and I'm supposed tae be okay with that?" She groaned and ran her hands through her hair, messing it up. "What I'm supposed tae do in the future, as The Black Bullet, makes me nervous. And then that'll affect my flyin'. What if I bugger up and that'll cause a really bad paradox!"

John put his arm around Jaime's shoulders in comfort. "I didn't know you felt that way!" He said.

"There's a TV series as well?" Alexia wondered out loud. "Anyway, how do you think I feel?" She then spoke to Jaime. "I'm signing books I've yet to write. Books that are based off your alter ego. It's alright for you. You've got Timelines, Time Senses and other abilities to work with. All I've got is nothing but guess work."

Jaime stared at her mum with wide eyes and realised she had a point. Other than the ability to talk to animals she had nothing else. "Well what the hell am I supposed tae do then?" She practically demanded out of frustration.

"Isn't it obvious?" Alexia spoke again. "You need to train yourself to fly Super-Sonic." Jaime shifted nervously. "I mean, you've got all those people to save." The woman added.

"Pika!" Sparky agreed and a hint of a smile appeared on Jaime's face.

"I'll help you," Jenny spoke up as she sat down next to Jaime. She was still excited. "With your training!" She then quickly added.

"And I'll help too." J.D also spoke up. He really wanted to be there for her.

Jaime sighed. "Okay, fine!" She replied in mock exasperation.

"That's good," Alexia uttered and turned to the TV. "Can the TARDIS pick up live Satellite feeds?" She questioned.

John frowned thoughtfully at the question. "Yeah, of course she does. Why do you ask?"

A grin appeared on Alexia's face. "Because The Doctor and Rose are going to be on Most Haunted Live."

"What?" Jaime, Amy and Rory all exclaimed.

"You've got to be kidding me!" J.D's eyes were wide. "How'd Rose manage to convince The Doctor to go to an event like that?" He wondered.

"With great ease apparently." Alexia answered, brows raised.

The TV had turned itself on and was showing several live Satellite feeds of a Stately Home in Yorkshire. Everyone sat down on the sofa, deciding to watch the live event.
