Hello! It's been busy considering I've been at home all this time... but I'm finally here with the last chapter of the power of six! I'm honestly so excited for this and I'm so sorry it's taken so long for me to finish it.

-----

On the way to the hospital, the Doctor whimpered in pain the way only making the Stone worry for him even more then when she was back at UNIT HQ, it was quite possible that his other heart could give out from strain if the other was not started again soon. He didn't have any regenerations left, he would die and so would she and possibly their baby, the baby that she could feel inside her, one that made her freeze for a moment in fear as they arrived at the hospital it could sense her fear.

The Stone shook her head and swallowed her fear, telling the Doctor now wouldn't help anybody.

"How many deaths have been recorded?" The Doctor asked using the Stone and Jenny for support.

"We don't know." She admitted. "We think it could be a third of the population."

"Kate, I have to find the wormhole, but the attacks could still happen." The Doctor said. "Tell the world. Tell them how to deal with this. The world needs your leadership right now."

She nodded. "I'll do my best."

"Of course you will." He smiled. "Good luck, Kate. Argh!" He cried out almost pulling the Stone and Jenny down to the floor with him when his legs didn't want to hold his weight. "Argh!"

"Oh, Sweetheart." The Stone murmured shaking her head and setting him on the floor with his back to the wall.

"Stone." He whimpered clutching her chest. "Please, go stop it."

"As soon as we get your heart working again."

"Not gonna happen."

"Then we're not moving." Jenny protested crossing her arms.

"I'm not going to last much longer." He forced himself to stand and brought out his sonic. "I need to locate the wormhole portal."

"Dad, you need to sit-"

"Hello." The Doctor cut his daughter off looking at a young girl with a cube in her hands. "You are giving off some very strange signals." The girls face glowed blue.

"Oh, my God." Amy gaped.

"Outlier droid, monitoring everything." The Stone explained taking out her own sonic. "If I shut her down, I can..." she muttered flashing her sonic. The girl staggered and the Time Lady lowered her to the ground. "Right." She turned to the Doctor and sighed when he was already heading off to find the wormhole.

The Doctor tried to grip the wall when he lost his legs again, falling to the floor he shook his head. "Ah. It's all right, it's all right." He winced. "I can't. I can't do it. I need both hearts!

"This is why you should have stayed at UNIT HQ." The Stone shook her head at him.

"I wasn't going to let you or Jenny go wondering around with cubes that can stop your hearts."

"Oh, and you can?" She shot back at him, her eyes practically flaring at him with anger.

"Yes, I can." He protested, the Doctor then winced at his chest.

"Doctor," Amy warned, seeing how furious the Stone had gotten.

"It's my job to protect you both." He looked up at his wife and daughter. "You're my family."

"So why did you walk into the cubicle with the cube?" The Stone crossed her arms over her chest.

"I needed to see-"

"You risked your life." The Stone exclaimed, and what happens to me if something happens to you?" She asked.

"So?" He shrugged. "We risk our lives all the time."

"So." She scoffed shaking her head at him. "So what Doctor?"

"I don't understand what's changed." He frowned. Sure they had Jenny with them but she had been in the TARDIS with the Time Lords for quite a long time now, she also helped Jack with the 465 and assisted UNIT. She was accustomed to their slightly dangerous life style.

"What's changed is that it's not just us anymore!" The Stone snapped making the Doctor stare at her before he frowned.

"I really don't understand-" he began only to be cut off.

"Doctor you really are clueless." Amy shook her head.

He winced before looking at Amy and frowning as the ginger who put two and two together, guessing what had happened. "What do you mean Pond?"

The Stone swallowed. Jenny face drained of colour at her mothers next words: "I'm pregnant."

The Doctors face followed his daughter. "Doctor?" The Stone looked at him alarmed when he didn't reply or moved, it was almost as if he was frozen, he could have been dead if it wasn't for the rapid movement in his chest. "Sweetheart?" She swallowed hard.

Amy worryingly looked around and spotted a portable defibrillator. "All right. Desperate measures." She ripped his shirt open. "All right, clear!" She shocked him. The Doctor gasped for a deep breath and jumped up, pushing himself away from the wall.

"Whoo!" He laughed dancing as the others stared. "Ooo! Welcome back, lefty! Whoa-ho! Two hearts, back in the game," he noticed the Stone standing rather shocked and pale, paler than he liked. "You're pregnant..." he murmured. She gave a small nod worried what he thought of the ordeal.

A smile grew on his face and he stepped forward before his hands found themselves on the Time Lady's waist. The Doctor wasted no time pulling her towards him, he then let go and cupped both of her cheeks, the Stone watched him closely, a soft smile on her lips as her eyes became damp as they welled up with tears, the Doctors eyes looked no better either. The Time Lord then pulled her in for a deep kiss. "I love you." He blurted out after they separated. He then leaned down to kiss her stomach over the fabric of her clothes, the fabic that covered where his son or daughter would stay for around the next 18 or so months.

"And I love you." He murmured against her currently flat stomach making the Stone chuckle and softly smile at the gentleness in his voice and the smile on his face that honestly made her love for him grow even larger then she thought was possible. The Doctor stood up and pointed at Amy. "Never do that to me again."

"Don't be stupid then." She countered.

"Can't promise that." He replied causing Jenny to snort at her father.

A bell dinged and made them all look towards a goods lift. "Ah, portal to another dimension in a goods lift?"

The Stone took out her sonic and flashed it at the lift before she shrugged. "The energy signals converge here."

"Does seem a bit cramped, though." The Doctor muttered. He looked around and poked a wall that rippled like a pond would. Grinning he took the Stones hand as well as his daughters. Amy smiled at the three of them

"Through the looking glass." They all stepped through.

They stepped onto a ship with dark metal and not much lighting.

"Where are we?" Amy frowned.

Jenny sniffed. "We're in orbit." She sniffed again. "One dimension to the left."

"Ooo." The Doctor looked at his daughter who grinned proudly. "You're getting good at that Jen."

"Thanks." She beamed.

"Rory!" Amy shouted spotting him lying on a slab next to Brian. The Doctor tossed a small vial to the redhead.

"Soborian smelling salts." He explained to Amy who glanced at the vial. "Outlawed in seven galaxies." She shrugged and waved it under his nose. Rory instantly shot up before ducking down next to Amy when they were shot at. The Doctor did the same making sure he was in front of the Stone and Jenny as they ducked with him.

"Whoa! Whoa!" He shouted. "What kind of a welcome do you call that?" He questioned. "And do you mind my wife is pregnant!"

"Pregnant?" Rory frowned and looked at the Stone. "You're pregnant?"

"Yeah." She nodded.

"I would hug you but I don't want to be shot at."

"We can all have a nice hug later." The Doctor shot the man a look. "Get them out of here. You two. Now!"

"What are you three going to do?" Amy asked.

"Absolutely no idea." The Stone shrugged. "Get him to the portal."

Amy and Rory moved over to Brian and wheeled his trolley. The man shot up as he was being moved and stared at his surroundings in confusion.

The Doctor went to move and was shot at making sparks fly. "Whoa!" He ducked down.

"So many of them crawling the planet, seeping into every corner." An alien with a bald head and what looked like cracked skin said making the two older Time Lords stare.

"It's not possible." The Doctor murmured standing up and walking to the alien computer. They watched the creature teleport to the other side and look at them through the transparent screen. "I thought the Shakri were a myth." He glanced at the Stone. "A myth to keep the young of Gallifrey in their place."

"Or was that just to keep you in place Sweetheart." The Stone chuckled.

"The Shakri exist in all of time, and none." The Shakri explained. "We travel alone and together. The Seven."

"The Shakri craft, connected to Earth, through seven portals and seven minutes. Ah, but why?" The Stone raised a brow.

"Serving the word of the Tally."

Jenny looked at her parents. "But why the cubes? Why Earth?"

"Not Earth, humanity." The Shakri answered. "The Shakri will halt the human plague before the spread."

"Erase humanity before it colonises space." The Doctor realised. "We thought the cubes were an invasion. The start of war."

"The human contagion only must be eliminated."

"Who are you calling a contagion?" Amy asked running in with Rory.

"Oi!" The Doctor looked at them. "Didn't I tell you two to go?"

"You should have learned by now," Rory replied.

"Yeah, and what is this tally anyway?"

"Some people call it Judgment Day, or the Reckoning."

"Don't you know?"

The Stone shrugged. "We've never really wanted to find out."

"Before the Closure, there is the Tally." The Shakri explained. "The Shakri serves the Tally."

"The pest controllers of the universe, that's how the tales went, isn't it?" The Doctor asked the Stone who nodded slightly shivering at the thought. She really couldn't remember the amount of times her mother had ordered what a human would call a nanny to tell her that story to scare her after she 'misbehaved' which was more like having fun.

"Wow." Amy blinked. "That's some seriously weird bedtime story."

"You can talk." The Doctor shot at her. "Wolf in your grandmother's nightdress?" Jenny snorted now needing to read that. "So, here you are, depositing slug pellets all over the Earth, made attractive so humans will collect them, hoping to find something beautiful inside." He narrowed his eyes. "Because that's what they are. Not pests or plague, creatures of hope, forever building and reaching. Making mistakes, of course, every life form does. But, but they learn. And they strive for greater, and they achieve it. You want a tally. Put their achievements against their failings through the whole of time, I will back humanity against the Shakri every time."

"The Tally must be met." The Shakri replied. "The second wave will be released."

"What does that mean?" Amy asked.

"I think it's going to release more cubes to kill more people." Jenny winced.

"The human plague breeding and fighting. And when cornered, their rage to destroy. You're too late, Doctor, Stone, The Tally shall be met." The Shakri then vanished.

Amy frowned. "He's gone?"

"He was never really here." The Doctor saod, "just the ship's automated interface, like a talking propaganda poster," he looked between the humans. "I can stop the second wave. I can disconnect all the Shakri craft from their portals, leave them drifting in the darkspace. Ah, but all those people who were near the cubes, so many of them will have died."

"I restarted one of your hearts."

"You'd need mass defibrillation." Rory added.

"Of course." He nodded, "Ah, beautiful. But, Ponds, Ponds. We are going to go one better than that. The Shakri used the cubes to turn people's hearts off. Bingo! We're going to use them to turn them back on again."

"Will that work?" Amy questioned as the Doctor soniced the ships computer.

"Well, creatures of hope." He shrugged. "Has to."

"Thirty seconds. Don't let me down, cubes, you're working for me now." An alarm on the computer beeped.

"Oh dear." The Stone muttered. "All these cubes. There's going to be a terrible wave of energy ricocheting around here any second."

"Run." The Doctor weakly supplied grabbing his wife's and daughters hands.

"I'm going to miss this." Rory said to Amy before they ran.

The ship exploded and forced the five onto their stomachs in the goods lift.

The two older Time Lords stood outside the tower of London with Kate Stewart. "You, er, you two really are as remarkable as Dad said." She looked at the two and kissed the Doctors cheek before hugging the Stone. "Thank you."

"My!" The Doctor grinned. "A kiss from a Lethbridge Stewart. That is new." He glanced at his watch. "Oh dear, we're late for dinner." He saluted Kate.

The Stone chuckled and lightly pushed him to the car. "Get in." She teased. "Or we'll never get there."

---

They got back to the Ponds house just in time for the take away; chinese food. The Time Lords chuckled at some of the Ponds stories. "Dear me." The Doctor said swallowing the last of his food. "We'd better get going. Things to do, worlds to save, swings to swing on." He chuckled. Jenny stood up and hugged the three Ponds before heading into the TARDIS, The Doctor went to head off and turned around. Placing one arm over Amy and Rory's shoulders. "Look, I know, you both have lives here. Beautiful, messy lives. That is what makes you so fabulously human. You don't want to give them up. We understand."

"Actually," Brian cut in. "It's you two they can't give up, Doctor." He smiled. "And I don't think they should. Go with them. Go save every world you can find. Who else has that chance? Life will still be here."

"You could come, Brian." The Stone suggested.

He shook his head. "Somebody's got to water the plants. Just bring them back safe."

"We always plan on it." The Doctor nodded wrapping an arm around his wife. They headed towards the TARDIS with Amy and Rory behind them.
