The explosion rattled the bars of the cell and Gwen had to hold onto to them to steady herself as the wooden hut that served as the jail shuddered.

"Bloody hell, we're under attack!"

Seska moved to the small window as another explosion shook the floor. "No, the explosion came from within."

"Sabotage," Gwen said as she grabbed the bars again.

Seska turned back to her. "No sabotage...its mother."

Martha checked Jack's pulse, he was still alive. She flinched when another explosion rumbled outside. She could see that Ianto was itching to move.

"Go, he's fine. I just need to give him the reversal drug."

She went to one of the cabinets and took out a small bottle. She sighed as she administered the drug.

"He did it again, didn't he?"

She sat back and within moments he began to stir. He let out a groan and rolled over and she smiled sadly as he blinked into awareness.

"Oh Jack, he's not the same person, not anymore."

The camp was in disarray when Ianto exited the med-unit; he knew exactly who had caused the explosion and he had no doubt that it was just a distraction. He knew exactly where that person was going; any parent would.

As he made his way through the mixture of panicked civilians and hurried soldiers, he caught a glimpse of someone flitting between the building next to the jail and the jail. He increased his pace, Gwen was inside with the boy and he didn't think the Doctor was in a forgiving mood.

The Doctor didn't stop to admire his handiwork; they would have found Harkness by now and no doubt they would have figured out the explosion was his doing and where he was going.

As he flitted between buildings he knew the explosions would have been picked up by the patrol drones and they would see what he could see; especially now he'd destroyed a certain something.

The Master would be coming, but he couldn't wait for him, he wanted out and away and take his son with him.

He froze when a group of soldiers ran past, heading for what he'd destroyed. "Good luck with that."

He could see the place he wanted and he could feel Seska's presence and the presence of someone else...a human. He snarled and quickly moved across the gap and he moved round the back of the building and started making his way to the front.

He froze when he felt cold steel against the nape of his neck.

"Going somewhere?"

The Doctor smiled when he recognised the voice. "Well, well, Ianto Jones," he said and went to turn, but the steel was pressed harder into his neck.

"Don't move."

The Doctor laughed and turned anyway and faced Ianto; he had to for what he was about to do.

"Ianto Jones," he said softly, his voice low and persuasive. "If you let me go, you'll have Jack all to yourself. You know he won't look twice at you if I'm here. Let me take my son and go and Jack will be all yours."

As he spoke his voice had become lower and silkier and he never took his eyes of Ianto's and his actions were very much like a snake ensnaring its prey.

Ianto had surprised himself at how easily he'd sneaked up on the Doctor, but he hadn't expected the Doctor to laugh and turn round.

The Doctor was saying something, but all he could think about was the fact that if the Doctor was still a prisoner, Jack would never look at anyone else. If he let the Doctor and his son go, then Jack would need someone to comfort him.

Yes, let the Doctor go a voice whispered in his head.

He lowered his gun and said. "Fine, I'll let you go."

The Doctor smiled. "Thank you, but there is one small problem."

Gwen wasn't expecting the Doctor to fall through the door and land on his hands and knees, and be followed by Ianto.

"Open the cell door for me," he said. "I can't take my eyes of him."

She nodded and gave Seska an apologetic smile and tapped in the code and the door clicked open. She turned back and found herself facing the barrel of Ianto's gun and a grinning Doctor.

"Very good, Ianto Jones...Seska, step out."

Seska almost bolted out and stood next to the Doctor.

"Gwen Cooper, if you would," the Doctor said and nodded towards the cell. "And of course Ianto...thank you," he said as Ianto obeyed.

"What have you done to him?" Gwen said.

"Oh nothing harmful, just a little persuasion."

"You won't get beyond the pass."

"I won't need to, the drones would have picked up the explosions and your little advantage has gone. The Master will be coming, so enjoy what time you have."

Jack was on his feet with minutes and despite Martha's protests he ran out of the med-unit and into the chaos.

He knew exactly where the Doctor was going and he sprinted towards the jailhouse. He'd nearly reached it when he heard the sound of the one things that shouldn't be and he looked up...drones and they were scanning...how the hell?

Then he knew what the Doctor had destroyed; the cloaking device.

"The drones!" he yelled. "Somebody shoot them down."

But he knew it was already too late, the Master would be coming and he would come in numbers.

He forced himself to ignore the drones and quickly scanned the compound, hoping to catch a glimpse of Gwen or Ianto...but what he saw were two figures running towards the main gates.

"Oh no. no, no," he said and covered the distance to the jailhouse in seconds. He kicked down the door and saw with huge relief an angry Gwen and a confused Ianto in the cell that Seska had occupied.

He wasted no time asking questions just opened the door and without a word he turned and ran out of the jail, knowing that they would follow.

He ran towards the gates but he couldn't see the pair of escapees. He skidded to a halt, Gwen an Ianto behind him.

"Dammit...open these gates!" he yelled.

The explosion had sent a wave of heat and sound high into the air and twenty miles and two thousand feet up, a group of five drones stopped suddenly. Three of them headed in the direction of the noise and heat and the other two hovered.

Only a few minutes later the duo shot away, heading for the capital.

The Master hadn't slept well, for one he was missing the presence and the warmth of the Doctor and little Jakaar was unwell.

At first he thought he was just missing his mother and had tried to comfort him but nothing worked and he seemed very warm.

He eventually called the physician and he did have an elevated temperature, the little mite was poorly.

"He needs mother," Ashena said as she mixed the medicine in with Jakaar's formula.

"I should have spent more time with him," the Master said as he cradled his son.

"How could you, this war has to be won."

"Still..."

They both looked up when they heard the noise.

"That sounds like..." Ashena said.

"Drones," the Master finished.

Two metallic spheres glided in through an open window and hovered above them.

"Descend," the Master ordered and they floated down to shoulder level.

A series of clicks filled the air and the Master said. "Show me."

Images appeared as holograms and showed a huge camp in disarray, but what took his and Ashena's attention was the two figures fleeing across the expanse of snow and red grass just outside the camp.

"Where is this?" the Master growled and a map overlaid the camp.

"But that's only thirty miles from here," Ashena exclaimed. "How could it be so close?"

Another image appeared and showed damaged machinery.

"A cloaking device, only somewhere important would have a cloaking device," the Master said.

Then another set of images appeared and the Master's expression hardened.

"Harkness," he snarled.

He turned to Ashena. "It's time you earnt your chosen name daughter. We are going to rescue your mother and brother and then we are going to take that camp apart. I want Harkness alive and uninjured."

"Yes father," Ashena said and bowed.

Minutes later the gates to the capital opened and armoured vehicle after armoured vehicle poured out and hundreds of men on foot and up above the air was full of lethal machines.

And at their head were the Master and Ashena, who was determined to earn the right to be called her chose name...The Huntress.
