The Doctor ended the call then and there. Anyone who knew about there son was trouble. For one only someone very powerful and therefore corrupted would've been able to find out about them and secondly Yvonne would only want to talk to them because they wanted to get their hands on Time Lord technology or genes.
Rose held Jack close, her arms wrapped round him protectively. She watched the Doctor anxiously waiting for him to say something.
"I'm going to give this Yvonne what she wants," he decided after a minute.
"What?" Rose stared at him. Surely he couldn't be serious?
"You and Jack stay here," he continued. "I'm going to find out how much she knows and put a stop to whatever she's doing."
"How do you know it's not a trap?" Rose asked, staring at the Doctor as though he were mad.
"I don't," the Doctor replied gravely. "But she won't stop. She'll track us down eventually and if we run she might not be so willing to hear us out."
"She might not," Rose protested but she knew the Doctor was right. If Yvonne wanted to talk to the Doctor then she'd probably stop at nothing to get to him.
The Doctor set the TARDIS in flight, following the phone call back to its origin. He wasn't surprised to find it came from London, Earth, and Rose's time.
"You stay here with Jack, ok?" The Doctor said. "The TARDIS will track me on this screen so you'll be able to see everything that's happening, but under no circumstances do you leave the TARDIS. Even if I'm in mortal danger, they mustn't get their hands on you or Jack, ok?"
Rose nodded, though she knew that if the Doctor got into trouble she wouldn't be able to stay put. He smiled and headed towards the door, glancing back before he left.
He found the TARDIS had landed in the office of Yvonne Hartley and she was sat at her desk watching him. She smiled when he caught her eye and gestured for him to sit down.
"Hello again Doctor," she said. "You came."
"Yup," the Doctor said a dark look on his face as he sat opposite Yvonne.
"Now where's your delightful partner Rose?" Yvonne asked glancing at the TARDIS. "And your son, Jack?"
"None of your business really, is it?" The Doctor snapped. "What did you want to talk to me about?"
"I believe you remember this," Yvonne asked turning in her swivel chair and pointing a remote at the wall which opened to reveal a TV screen. The footage playing on it was of Rose being tortured several months previously when she'd been kidnapped for the purposes of having the Doctors child.
"That was you?" The Doctor frowned at her. "But Time Travel shouldn't be possible for another thousand years at least!"
"Ah but that's by human standards," Yvonne said smiling. "You have to remember that aliens have been time travelling for centuries. You, for example Doctor, have your marvellous TARDIS and alien spaceships have been falling to Earth for years, it just took the right mind to use that technology."
The Doctor's mind raced. This all sounded horribly familiar. The last time someone had done something like this he'd ended being tortured, not just by his captive but by an escaped Dalek as well.
"You're not the first person to say that," the Doctor said quietly trying to ignore the video footage now. "And I seem to remember he had his mind wiped."
"Doctor, Doctor, Doctor," Yvonne laughed softly shaking her head. "Torchwood has a saying, 'If It's Alien, It's Ours', and I intend to stick by that saying, which would make you, Rose Tyler and your long awaited son our newest exhibits."
The Doctor looked at Yvonne for a moment and then stood up. He was shaking with anger now and could barely contain himself.
"I'm going to give you a choice, Yvonne Hartley," he said, his voice dangerous. "Either close down Torchwood or I will do it for you."
Yvonne's smile slipped from her face and she stood up, smoothing down her top and placing her hands on her hips.
"Doctor, you are not really in any position to be giving me orders," She said gravely. "You, as of now, belong to Torchwood and have no rights whatsoever. Take him away boys."
Two bug burly men grabbed the Doctor from behind and dragged him off kicking and screaming, literally. Yvonne pressed the button on the intercom and began to speak to her receptionist.
"Sandra, send up the men in white," she said smiling maliciously. "Tell them I've got them a little present."
"Yes, Yvonne, Ma'am," Sandra replied, her voice scratchy over the intercom.
Meanwhile Rose had watched the whole thing form the safety of the TARDIS. She'd heard the whole conversation and held Jack tighter in her arms. If Yvonne thought she was going to get hold of her son she had better think again.
She pondered what exactly she was going to do, but the decision was taken out of her hands when several men in long white coats began to wheel the TARDIS into a laboratory.
Rose knew they'd never get in, but how was she going to get out? She couldn't just sit here and leave the Doctor to protect himself. But at the same time what was she going to do with Jack?
She was just going to have to wait it out then. Once the men realised they weren't going to get in anytime soon maybe they'd leave and she'd have time to sneak out and rescue the Doctor. With Jack in tow.
The Doctor was once again strapped down on a table with a lethal looking laser aimed at him.
"You're making a big mistake!" He shouted at Yvonne who was conveniently sat behind a thick plate of glass so she couldn't hear his screams. "You'll never get hold of what you want by torturing me!"
Yvonne just watched as the Doctor writhed in pain. She couldn't hear him and probably wouldn't have been affected if she could. She had the TARDIS and it was only a matter of time before they got hold of the Time baby.
"Please!" The Doctor tried again. "You won't achieve anything by this! The only thing that's likely to happen is I'll regenerate!"
Yvonne smiled as she watched him mouth wordlessly. She knew what he'd just said and pressed the button for the intercom.
"Well it's a good job that I want you to regenerate then isn't it?" She said, no hint of remorse in her voice.
