Jack ran down the corridors as fast as his legs would allow, heading for the labs on the south side of the building. He knew that he wouldn't have long. Torchwood would work out something was wrong when the Doctor appeared in their midst again.

He only passed a few people, having opted to take the quieter route, but even the people who he came into contact with didn't notice who he was. People ran about the building all the time, it wasn't anything different.

Jack made it all the way to the testing labs without facing any opposition. As he expected there were guards on the door. After Rose's outburst Yvonne had obviously realised that they'd be after the cure.

Jack riffled through his pockets and found a small ball of powder. He crushed it in his hand and blew the powder towards the guards, covering his own mouth and nose with his top.

The guards, as soon as they smelt the powder, dropped to the floor, unconscious. Jack grinned to himself and punched the air. Walking forward he used his pass (risky when the systems would be being watched) and opened the door. As he gazed in he froze, suddenly finding that getting the cure would be a little harder than previously thought.

The Doctor was blindly running through the busiest areas of Torchwood, dodging guards and other personnel as he made sure he created as much chaos as possible. He hoped that Jack would find his path easy because the Doctor wasn't sure just how long he could keep the security chasing him before they got suspicious.

"Catch him!" One guard shouted to his inferiors getting annoyed that despite the close proximity the Doctor still seemed to stay just out of reach of their hands.

"I've got him!" Another called diving for the Doctor and missing as the Time Lord ducked out of the way just in time.

"There's hundreds of us, stop messing about and just corner him!" A third said and the Doctor realised that they were herding him into the corner. He quickly changed direction and began running down a corridor, tossing trolleys out the way as he passed.

"Catch me if you can!" The Doctor jeered, causing the guards to double their efforts. Of course this was no match for the alien who could see their moves happening before they did.

Baby Jack was steadily getting worse. The rash was spreading, causing him to look very red in places and is temperature was so high Rose was surprised he hadn't just melted in her arms.

The skin that was still free of the rash grew paler and paler. Rose wasn't sure how much longer he was going to survive. Charlie stayed with her the whole time trying to comfort her, keep her talking to distract her from the main situation at hand, but it didn't stop her worrying.

"Where are they?" She asked after what seemed like years.

"They'll be back," Charlie assured her.

"They better," Rose said, some of her old demeanour showing. She wasn't sure she'd be able to cope if she lost the Doctor as well.

"They will," Charlie said firmly.

"Sorry," Rose said realising that she was panicking. She smiled at Charlie. "If you knew her then you'd tell me I sound just like my Mum."

Charlie smiled then frowned. Hang on…. Her mum…. His mind raced as he thought about it. He might've been wrong… he might be worrying for no reason. But what if he wasn't?

"Your surname's Tyler, right?" Charlie asked carefully.

"Yeah," Rose nodded confused, wondering why it was important.

"Your mums not Jackie Tyler is she?" He said his fingers crossed.

"Yeah, why?" Rose said her heart thumping.

"When we're done here you better find her," Charlie said. "She's Torchwood's most wanted after you and the Doctor."

Rose stared wide eyed. No… they wouldn't get her mum as well. There was no way in hell that Torchwood was going to take her family away from her. Then a sudden thought occurred to her.

"What about Mickey Smith?" She said, standing up and rocking Jack.

"After your mum on the list," Charlie nodded standing up too. "But Torchwood hasn't been able to find either of them. As soon as Torchwood started asking they disappeared."

The Doctor panted, his weary legs starting to fail. He really shouldn't be exerting himself this much this soon after a regeneration, especially one that was forced.

The guards were starting to close in on him. He could still manage to stay just out of reach, but not for much longer. He'd have to head back to the TARDIS. He just hoped that Jack had the cure.

"Well, well, well," Yvonne stepped forward clutching a vial of blue liquid in her hand. Her face was scratched and still covered in blood from where Rose had attacked her. Jack coward slightly at the menacing look on her face. "Jack Harkness, looking for this?"

"Give it to me," Jack said sounding braver than he felt.

"Why would I do that?" Yvonne asked smiling maliciously at him.

"Because then your son might believe that there is some good in there somewhere," Jack replied his eyes never leaving her gaze.

Yvonne didn't say anything for a moment and Jack knew he'd hit a heart string. Despite her outward appearance, Yvonne did have one soft spot.

"I could just kill you," Yvonne said her voice shaking.

"Charlie really would hate you then…" Jack held out his hand waiting to see if Yvonne would hand over the cure.
