White Coat was displeased...his men had searched and dug the area where the body of his property would most likely have come to rest but no carcass was forthcoming...could his property have survived? And if it had...where was it?

Of course, how remiss of himself; he had the perfect tracking device. He took out a small device and adjusted a few dials...and there it was.

"Commander!" he called and then said more quietly, "it seems my property has become Lazarus."

The Master was trying to calm the Doctor who had once again fallen into a restless sleep. Monsters...what kind of monsters could frighten a Time Lord?

He sighed; he could do nothing, not with their bond in tatters. He tightened his hold on his lover, who pressed closer to him in response to the pressure; at least he wasn't trying to kill him and the way he'd clung to him like a frightened child meant that somewhere inside a tiny part of the bond was clinging on.

The Doctor let out a sigh and moved again and the movement exposed that much loved throat. It was then that he saw a glint of metal under the Doctor's collar.

Why hadn't he noticed it before?"

Carefully he loosened the Doctor's tie and opened the Doctor's shirt...it looked like...yes it was a collar, and to the Master, a collar meant only one thing.

Someone else had claimed ownership of him.

"Oh no, I am not having that," he said and reached out to touch the collar.

The Doctor's eyes flew open and he flinched, the look of fear in his eyes making the Master hesitate.

"It's okay, I just want to look," he said and reached out again and touched the collar.

He felt the Doctor tremble and he said softly. "Still, Eresh'ala," and the trembling lessened but didn't stop.

"Ni'ala...don't, please," the Doctor whimpered.

The Master ignored him and said. "Whoever put this on doesn't own you. You are mine and I need no collar to show it."

He felt round the collar and found what he thought was the lock and smiled when there was an audible click as the collar unlocked. He carefully removed it and scowled when he saw the chafe marks on the Doctor's neck.

He dropped the collar with a look of disdain and said. "See, you belong to me." He cupped one of the Doctor's cheeks and said. "Who put this on you?"

The Doctor blinked and a tear escaped. "Mesis Tesri."

Jack had been woken by the Doctor's cry, attuned as he was to anything to do with the Time Lord.

In the quiet of the cave he could hear the murmured words coming from behind the blankets.

He sat straighter when the Master exited and Jack saw the collar in his hand and his blood ran cold; only one person used a collar like that and only one person would have the gall to put one on the Doctor.

Only one person would treat him like livestock, and that meant he had the Doctor's son.

"He's here, isn't he?" the Master said.

Jack nodded. "The collar, it's his handiwork."

Jack couldn't blame the Master for being angry.

"He collared him like a dog. I'll find out how this thing works and I'll put it round his scrawny neck. I take it this was used as some sort of correction."

Jack nodded and took the collar and flashes of bad memories flicked through him as he handled it. "It's a piece of work, just like him. He's a cancer, you think you've exorcised it but it keeps growing back."

"Then I'll cut him out," the Maser snarled.

"Just let me have a piece of him," Jack said and handed the collar back. "You should sleep."

The Master snorted. "Why, so you can get next to him?"

Jack didn't rise to the bait. "No, you're the only one who can control him. If he decides to run we're not fast enough or strong enough to stop him."

The Master let a humourless laugh. "If he decides to run, not even I could stop him. But you're right...I should sleep."

Jack stood. "My watch, try not to rile my team."

The Master flashed him a grin that would have been charming, if Jack didn't know him better.

The camp except for Jack fell back into sleep.

He wanted to turn away from the horror he was seeing, but they didn't let him. He was held fast, his head painfully so.

"You will watch," a voice hissed in his ear. "And you will submit to me and open the gateway or they will burn in a hell of my making."

"I can't," he said.

"Cannot or will not," the voice said and the owner of the voice stepped in front of him.

"Then they will suffer my fire."

"No!" he screamed.

The screams that floated to his ears shattered his hearts and broke his soul.

"Please...stop it...oh Rassilon don't...I'll serve you...I'll serve...please...stop it."

"Wise choice, Time Lord. But you must be punished for defying me."

At first he didn't feel it, he was too much in shock at what he had seen but then his mind was taken by something else and within seconds he was screaming as he felt like his blood was boiling.

The first wisps of smoke curled from under the blankets but it went unnoticed by the sleeping forms.

At first the blankets just smouldered and then caught light and flame began to lick at the material.

The fire spread unnaturally fast and it was the heat on his back that roused the Master and it was his shout of alarm that roused the others.

He scurried away from the flame until he realised it source and started to move towards it.

But he was stopped by the heat of the flames...it felt unnaturally hot and the flames burnt with a strange colour.

Then the frightened cry from behind the wall of flames overcame his natural fear of fire and before anyone could stop him, he leapt through the flames.
