Back in London, Jack and the Doctor were working side by side. Ianto was keeping tabs on the 456's activity and Johnson's team were looking after Alice and Steven. "Like old times, hey Doc?" Jack asked as they dragged a thick, and heavy from the look of it, cable out of the TARDIS.

"If by old times then you mean when you were a con man and it was your fault that the world's population was slowly turning into gas masked children looking for their mothers, then no," The Doctor said.

"Hey!" Jack said. "Everybody lived."

"Do you still have that square gun?" The Doctor asked.

"Yes, unless it got blown up in the explosion," Jack answered. "Will we be able to stay on track now?"

"Doesn't look like it," The Doctor answered.

"Sir?" Ianto said.

"Yes Ianto?" Jack said.

"The 456 seem to be getting a little impatient," Ianto replied. "Jack, I'm worried about Mica and David."

"Don't be, they'll be fine," Jack told him as he continued to prepare the cables for the plan he had come up with (Which the Doctor had fine tuned) that he wouldn't explain to Ianto. "Gwen and Rhys are looking after them."

"Yeah," Ianto said, his eyes drifted over to Steven and a smile quirked at his lips. "'Suppose he's kind of my grandson too now, huh?"

Jack laughed. "I suppose so, yes," He agreed as he and the Doctor connected the wires to the computers. Each wire leading to a cable these cables created a vast network of complex electronics leading to the TARDIS control panel. And whilst Ianto boasted of knowing everything, this only extended to Earth's history involving the brief interactions with Alien's over that time. He had no idea what the two ancient aliens (Whilst Jack was human he was from a far of planet in the distant future so he counted as an alien).

"We ready now Doc?" Jack asked.

"Should be yes," The Doctor replied.

"What exactly have you done?" Ianto questioned, gesturing to the web of wires across the floor.

"Well on a basic level we've connected this computer to the TARDIS," The Doctor started to explain.

Ianto stopped him there. "This is a laptop," He pointed out. "Couldn't you have carried it into the TARDIS?"

"Well, yes," The Doctor said. "However, within the TARDIS There is no port that is compatible with any wire we could attach to this laptop and vice versa. All of this cable is making various connections in various places to make it so that the entire thing will work. Add to that that we actually need the sound to travel through a certain amount of wire, to replicate it travelling through the nervous system of a child and then we need to make sure that it will actually reach the 456. It's all a lot more complicated than my timey wimey detector, which goes ding when there's stuff." Ianto blinked. He turned to Jack.

"There isn't a cable that would link the laptop to the TARDIS so we improvised," The other immortal explained. "When he rambles like that, I like to think of it as the TARDIS giving up on translating him and spewing random words instead."

"Translating him?" Ianto asked.

"The translation circuits in the TARDIS make it so no matter where you are, you can understand what others are saying," Jack explained. "Now I think that the Doctor doesn't actually speak English, or any other language than Galiffreyan for that matter, and the TARDIS translated him into English."

"Oi!" The Doctor said. "I can hear you over there doubting my intelligence."

"Well what else am I supposed to think when you ramble on without any actual point?" Jack laughed.

At that moment Steven ran up shrieking with laughter. "Uncle Jack!" He yelled. "Uncle Jack! Help!"

"What is it Steven?" Jack asked his grandson crouching down to his level. The little boy threw himself at Jack and pushed himself as close as possible, still laughing. A small hand lifted from Jack's shoulder and pointed over to where the soldiers were playing football earlier. They now appeared to be playing tag - which was equal parts disturbing and hilarious. One had stopped just a few feet away, he appeared to have been chasing the boy. "The soldiers?" The little head bobbed against his chest. "What did they do?"

"They're cheating at stuck in the mud!" Steven cried out as he pushed himself up on Jack, who nearly fell over.

"Well you go and tell them that your Uncle Jack will deal with them once he's saved the world," Jack said, urging the boy to go back over to the soldiers and continue playing.

"Alright," Steven said, before running off with the soldier.

"When are you going to tell him the truth, Jack?" Ianto asked.

"That's Alice's decision," Jack said.

"Right then, all set," The Doctor said pushing himself away from the computer.

"Right then Doctor, let's save the world," Jack said with a grin, taking Ianto's hand.

"Allon-sy!" The Doctor yelled as he hit the button. Every child around the world stopped and let out a high pitched almost choir worthy continuous note. All eyes with in the Torchwood 1 warehouse turned worriedly to Steven. Gwen, Rhys and Rhiannon exchanged scared looks as the children there started the note.

All over the world the same note sounded. And in its glass case, the 456 screeched and wailed and sprayed that disgusting green mucus everywhere. It screamed and screamed and screamed.

The TARDIS was sparking, small explosions going off within. Smoke was beginning to billow from the doors, Jack and Ianto covered their mouths and noses with their arms. The Doctor ran his hand down her frame, as he said "You can do it girl, not much longer now."

An almighty wail, accompanied by the largest explosion yet within the TARDIS, from the 456 and it for all intents and purposes popped. The creatures blood covered the inside of the glass container and then it filled with flames. All evidence that the 456 had ever been within that glass caged disappeared as the flames receded. At the exact moment the explosion happened every child stopped singing (For that was really what had been happening) and cheered instead. Unanimously and simultaneously, the world's children cheered.

Gwen and Rhys hugged. Rhiannon found Mica and David and hugged them close. Ianto and Jack hugged each other. The couple where soon joined by and ecstatic Steven and a very relieved Alice.

Immediately the soldiers started to escort children home. Rhys pulled the panel back to allow everyone back out. Everyone who had been trapped within that building took an almighty breath of clear air in relief once they were out.

But not everyone was celebrating. "No no nonononono!" The Doctor cried as the TARDIS doors slammed themselves shut. "No girl, don't do this! You've just saved the day!" He pushed at the door, trying to open it. All of the wires that had been linking the laptop with the TARDIS had been severed as the door shut. "Please let me in."

"Doctor?" Jack asked. "Is she alright?"

The Doctor ran a hand through his hair. "She should be fine," The Doctor said. "But it looks like I'm trapped here for a little while."

"How long?" Ianto asked, pushing back on Jack - who was in the middle with Steven and Alice at his back.

"Hard to say," The Doctor said. "It depends on how badly damaged she is, and since she won't let me in, I can't see how bad it is."

"You could help us rebuild?" Jack suggested. "We can have the TARDIS moved up to Cardiff, she can use the rift energy to help herself rebuild, right?"

The Doctor laughed. "Are you trying to recruit me Jack?"

"Well, why not?" Jack said. "You're still on the UNIT pay role."

"Alright," The Doctor agreed. "Until the TARDIS is fixed, consider me a member of the company originally created to kill me." Jack laughed. Ianto frowned.

"Is that really what Torchwood was created for?" He asked.

"You worked at Torchwood 1," Jack said. "Ask yourself that." Ianto thought for a moment before shrugging.

"I suppose it was," He conceded. "But you changed Torchwood 3 sir."

"That I did, Ianto," Jack agreed. "Johnson!" He called out. The woman acknowledged him. "Can you get us to Cardiff?"

"Already on it Captain," She said. Not too long after this the Doctor, Jack, Ianto and the TARDIS were on a Helicopter heading for Cardiff. Rhys would be waiting with a lorry to take the TARDIS to the bay area where it would be placed outside of the tourist information office. Gwen, Andy and Johnny had managed to get the SUV back and would also be waiting to give Jack, Ianto and the Doctor a lift. From the cog door right through to the information desk the hub was still intact.

Upon reaching the ruins of the hub, Ianto looked horrified. "How did you even come back from that Jack?" He asked.

The Doctor answered for him. "He's a fixed point in time and space. There can't be a single moment that he isn't in."

"Does that apply to me now too?" Ianto asked.

"I'm sorry," The Doctor said. "I'm so sorry, but I couldn't let Jack become some washed out shell who would make any sacrifice, even the lives of those he cared for, simply to get the job done. It wasn't about saving the world. It was about doing the job, and doing it right. And I'm sorry Jack, but that is- would have been the darkest you had ever been, and you've been a con man."

Jack and Ianto stared at the Doctor. "Thank you," Ianto said.

"For what?" The Doctor asked.

"For saving Jack from himself," Ianto clarified. After a brief pause, where no one said anything a screech was heard. "Myfanwy?" Ianto whispered, hoping against hope that she was alive. A screech was heard again. "Does anyone have any dark chocolate?" Those present shook their heads.

Jack reached for his Vortex Manipulator and pressed a particular button on it. Myfanwy heard the signal and flew over to the group, she nuzzled Ianto, who laughed. "You have a pterodactyl?" The Doctor asked in awe.

"Yep, caught her with Jack the day he recruited me," Ianto said.

"You mean the day I relented to your pestering because you could actually be useful?" Jack teased.

"Let's see, what was the first thing I did for you when we met?" Ianto asked. "Oh yeah, saved you from a Weevil, then I made you a coffee and then I caught Myfanwy with you."

"Okay, I get it," Jack said, holding his hands up in surrender. "You're useful."

Gwen decided to interrupt them. "Don't you think we should work on rebuilding the hub?" She asked.
