Malcolm kept wiping the stress brought on sweat from his brow, all the while his eyes were locked on Adrian. Akana was looking from Malcolm to Adrian, "why are you still panicking?" She hissed at him, "if he's dead, the threat had passed, now we have to look after the interests of my people." Anyone who didn't know the Doctor, or had no idea what Malcolm was panicking about, would probably have snapped at her for being insensitive. As it was, Malcolm knew there was still a threat, "he's not dead, if he dies - we are dead...and so is most of London." His words were quiet, only for the Silurian next to him, he didn't want to start a panic, after all, there wasn't anywhere in England (that they could get to in time) that would save them.

The creature headed towards the vault, his clothing had shifted from the donated clothing to mimic the eleventh Doctor's attire. The copy of Cassie was right beside him, keeping up a charade was wired into his DNA and so hers as well. Even while he was relaxed as he walked, no longer concentrating on acting like the Doctor, he still moved like him, muscles copied too closely to move any differently.
He didn't pause as he walked into the vault, Martha was too busy to notice, she was staring at Adrian's hands, willing the golden light to reappear. 'I'm sorry, I didn't know, I'm so sorry' her mind kept running over the same useless, scattered thoughts. When she did notice, her weapon, which she had holstered (as Jack had pulled her away) was once more in her hand as 'the Doctor' walked into the room.

The Humans and Silurian were standing at the back wall of the vault from the door, across the room from Adrian. So when the creature walked into the vault and up to the near-corpse of Adrian, he seemed to be a safe distance distance from them. But no one in the room could have any idea what this creature was truly capable of. 
The monster looked down at Adrian, as Martha had raised her weapon, the other soldiers had done the same. Malcolm grabbed Jack's shoulder and shook his head, when the other man had moved in such a way that gave the doctor the impression he was reaching for his own weapon.
"My dear...companion" the creature spoke, he was using the Doctor's voice but not his tone, this was too 'sweet'. The Cassie copy, who had been grinning at the real Cassie from the point she had walked in the room, now gave all of her attention to her 'master'. 

"Kill the soldiers, leave the...tastier ones for me." Cassie grinned as he gave the order, then her gaze turned to the Human soldiers. Before the men could react, she carried out her order, Weeping Angel style, it took only a blink for her to complete three actions. The first was raising her right arm, the second was stretching that arm, the third was driving it though the soldiers. There was a fourth action but it took longer, as the black flesh of Cassie's copy wound through the group, it began to spread through and convert the bodies it had impaled. In a matter of seconds, the men had turned to black goo and been absorbed into the arm/tentacle. The copy drew it back into her self, she took a moment to pull Martha's gun with it, then just for effect she licked her finger tips. She hadn't even given the soldiers a chance to scream, but any who had viewed their faces would have seen the pure agony in their expressions.

Now the monster looked at the group, "I have something to finish, you will have to bare with me a moment." At this, he knelt down and grabbed Adrian around the throat, lifting his limp form from the floor and into the air. The ease with which he did this made Adrian look as if he weighed nothing at all.

Elsewhere, the man in question stared at darkness.

"Don't leave me"

A stranger's voice echoed through darkness. Adrian was floating in something, his fingers twitched as he tried to identify the texture, it was a slimy liquid. No...not slimy, more like powder...but it was a liquid at the same time...
He frowned, his own description confused him, the substance was cool though, relaxing, comforting and somewhere he felt he wanted to stay.

"Please don't leave me"

The voice echoed again, he could understand the words, but he couldn't recognise who the speaker was. 

"Don't leave"

His face relaxed, his lips pulled back in a contented smile. It was far easier to just enjoy the sensation of the strange liquid around him that to...what was that word? He frowned again, but just before he was about to let the thought go, it came to him.
Fight.
It was far easier to give in than to fight.

"Don't leave us just yet, the party has only just started." This voice didn't just echo through the darkness, it rumbled in its very foundations. 
Outside the creature placed his free hand on Adrian's chest and grinned, the reason for his expression became clear moments later.

Blood began to seep through Adrian's clothing once more, the hand that had once been on his chest had split in two. Tentacles of black sludge had buried them selves into Adrian's chest, digging inside to grab the pair of hearts and begin a macabre form of CPR. The monster kept 'beating' the hearts a their otherwise natural rhythm.
The glow began to return to Adrian's hands.

In his mind light opened above him, he felt a pull begin to draw him out of the strange liquid. Now he found the will to fight, he wanted to stay in the darkness, there was something in the light he didn't want to see, didn't want to feel.
"Come now, wake up, my dear friend, this isn't the time to sleep" the voice was close, Adrian didn't want to see the source, didn't want to-

Too late.

Adrian opened his eyes to the discomfort of something in his chest. 
He looked down, the had that had been at his throat had moved to his shoulder, the monster wanted him to see this. The pain only hit him as his eyes settled on the sight of the things in his chest. This was the point he began to yell and struggle, but it counted for nothing, he moved so weakly, creature only laughed and began to withdraw its tentacle. Adrian quieted as the golden energy sealed the wounds that had ironically brought him back from the brink of death. Without the pain to keep him aware, his body was now trying to concentrate on healing, staying awake was becoming harder and harder.
He stayed standing with the support of the creature as the hand on his shoulder moved back to his throat and lifted him in the air again.

His eyes rose as his body did, gaze settling on the creature, his memories of the last time he had been awake returned. He tried to look at Cassie, but both versions were too far for his restrained gaze to find. His eyes moved back to the familiar face, he couldn't have spoken even if his air passage wasn't blocked. The part of his mind now awake and aware wished the man to just kill him, get it over with, save these people's lives. Another part wondered though, what sort of people were they to seek a man like this to save them? 
The tiniest part of his mind, not fogged by pain or anguish, began to understand what he was looking at.

"There's no need to play this game any more" 'The Doctor' placed Adrian back on the ground and the monster's hand again moved from his throat to his shoulder, holding him up. Adrian's head was hanging forward now, gold pulses under his skin were getting stronger.
Adrian felt as his head was held under his jaw by the Doctor's free hand, his face turned this way and that as the other man looked at his appearance. How ever fog filled mind was, he couldn't help but pick up on 'the Doctor's' next words.
"Doctor, you didn't change much in your last several regenerations - not that they lasted that long." If he hadn't been held up by his shoulder, his body too weak trying to heal itself to struggle, he'd have stumbled back in shock. "Is a tampered scanner all that you need to give up on life?" The planet eater grinned as Adrian no longer needed his support to lift his head and meet his eyes. His injury slowed mind struggled to understand, to get past his initial thoughts of being the...very creature standing before him. 

"Then..." Adrian tried to form the question, get his head around the creature's near enough admission that he wasn't this 'Doctor'. For those with a clearer mind, the fact the monster called Adrian 'Doctor' should have been enough to prove who the amnesiac really was. But in the time it was taking for Adrian to wrap his mind around this fact, the hands the creature had on his jaw and shoulder moved to either side of his face. 

"Save the messing around, Doctor, give me what I want" the creature grew several inches as he spoke. It's legs and torso stretched oddly, he seemed to forget about the audience, the meals could wait, he had something far more important to find out. Adrian's reaction to the now much taller man was nearly instinctive, "my name is Adrian" the words were stated, clear, if quiet due to the state he was in. "Enough, give me what I want and I'll leave this planet, you've given me a good game...I'm feeling generous." The creature didn't sound generous, he sounded angry.
But Adrian was looking at him blankly, not understanding or remembering what it was the creature wanted. "I don't-" "I have lived far longer than you, far longer than your now dead race, Time Lord. Do not play with me, the process your body is now ready to undergo, I want it, I want your power of regeneration." His voice didn't even sound remotely like the Doctor any more. Instead, it was as if he was speaking with the voices of all of the people he had killed and absorbed.

Adrian was now finding the strength to try and pull the creatures hands from his face, but his still weak attempts did nothing. The creation was still mimicking Cassie, it was now standing in front of the group, keeping them from moving to try and help. "You somehow kept it from me, you have it, you can tell me how to-" he stopped as Adrian's eyes locked on his, the light there was no longer confusion, his struggling had increased as the pulses of light beneath his skin lasted longer. "Ah" the creature's breath came as a whisper, he shrank back to his body's normal size and wrapped his arms around Adrian. "No-" he managed in a strangled whisper.

Adrian's struggles meant nothing as the form of the copied eleventh Doctor's body turned back to the creature's black near liquid flesh. Martha grabbed for Jack's weapon, back handing Malcolm aside as he moved to stop her. She grabbed the pistol and wrenched it free of the holster, only Akana was heeding Malcolm's motioned pleas for those armed to not fire. All the while, Cassie's clone was laughing.

Martha emptied the revolver into the black egg that now surrounded Adrian, but the bullets bounced off. As much as it resembled liquid, the substance was perfectly solid.
Akana forcefully held Martha back as she made to attack with another weapon and grabbed Jack's arm (pre-emptively) incase he chose to do the same.

But even the Silurian's arm slacked as the clone of Cassie began to scream, Malcolm initially looked at the real Cassie to see if it was anything she had done. He and Akana had been too far from her (blocked by Martha and Jack) to stop any action she may have chosen to take. As it was, anything she had chosen to do was not the cause of the copy's agony.

The egg was no longer its original shiny black colouring. Instead, in several places the surface seemed to have thinned, the most interesting thing was that through these thinner areas, was golden light.
"The planet eater just saved our lives..." Malcolm murmured, awed by he sight.
The thinning areas turned to cracks and molten edges fell inwards, the copy stopped screaming as this started, falling into the sludge that was its real form. 
The light dimmed as enough of the egg fell away to release the rays to such an extent that if it had been as bright as it had started out, the group would likely have had to cover their eyes. 

Instead, as the last pieces fell to ash, Adrian, looking exactly the same as before, though far healthier and fully healed, was left standing at the centre. The man looked at them and blinked, Martha made a move first towards him, but he raised his hand to wave her back. "There....there's..." He sounded out of breath, but Malcolm finished it for him, "there's more" he was holding his scanner again. "Not enough to cause anyone harm if we stay at this distance...I think this is...normal."

"Cassie..." Adrian whispered, his eyes falling on the blonde, his expression apologetic and pained.

As if to prove Malcolm's point, Adrian's arms were thrown out at his sides against his will, equally so for his head as it was thrown back. The uncomfortable position he was forced into was hidden by the bright stream of golden light. It was no longer restrained by the darkness he had only moments ago burned away. 

In his mind everything burned, Adrian could almost taste the memories that kept him from being the man he had been before. He reached out for them, every beat of his heart - his hearts - echoed the name of a race, his race, 'Time Lord, Time Lord, Time Lord, Time Lord..."
In the light he could see silhouettes of people, thirteen men stood and watched him. Because of the bright light behind them, Adrian couldn't see any detail of their faces or even their clothes. Just their stances stood out as familiar to him, but that was it for any true memory.
Then he noticed one of the thirteen was missing, he turned his head and found himself face to face with the very creature that had caused his death in the first place. His first reaction was to stumble back "Calm down, I'm not that...thing" the stranger tightened his bow tie, "I'm the original" he frowned then, "sort of." Adrian was still gaping at him, "oh don't give me that look, I only mean that...technically, I -was- the original, I was the first out of the two of us to have this face" he grinned as if he'd said something smart.
Adrian couldn't actually understand what he had said.

"And now?" It was the only two words that could leave his lips at the moment, "now? You're the original" Adrian relaxed, of only slightly at these words.
"Where are we?" He felt as if his head was moving awfully slowly, "that's because it is" the man, the Doctor, the 'eleventh' incarnation answered the unspoken question first. "We're in your head - our head, some things need moving around." Adrian looked around, all he could see was light, bar the silhouettes, it was almost peaceful - but it hurt his eyes...if he had any with this not being real and all. When he looked back the eleventh had changed, "does this make you feel better?" The Eleventh had changed, thinner, older, the Tenth now stood next to Adrian and the amnesiac visibly relaxed, he nodded. Now he wasn't faced with what had been a nightmare the last several days, he could think clearer, if only a bit.

"What needs moving around? Why can't I remember anything if we're in my...our...head?" Now the Tenth grinned, similar but bigger than the Eleventh's it even touched his eyes. "I think I'm going to take a back seat, all these memories can be overwhelming, get your feet, make a mark in here. Then....it'll still be you when you do remember everything, you won't be...'over written'". 
The Tenth stepped away from Adrian then, walked towards the other silhouettes, "you'll remember this - and don't worry, we'll always be here, watching...in a good way." He paused and turned around, "and stop thinking of Rose when you look at Cassie, they really are very different." Adrian frowned, "who's Rose?" He called, but the Tenth had already joined the others.
"Keep her close, keep her safe, she's good for you." The words were whispered into his ear by many different voices, not as many as the monster had spoken with, just thirteen.

Finally his eyes opened to the real world, now the burning was back and it made him want to cry out but he wasn't sure if he actually managed it or not.
What was left behind as the light died was a very different looking person. He leaned against the scanner, the clothes once worn by the Adrian Cassie would recognise were still on his body, but they were clearly too tight on this new form. A noticeably taller man had taken his place, eyes dark enough to be mistaken for black fell on Cassie. His hand reached up and pushed aside hair that had grown nearly down to his shoulders. Now his view of Cassie was clear, he could see the way the others were looking at him. He frowned and reached back to the hair he had nearly pushed aside without a thought, there wasn't anything in the way of curls in it. The shade of his hair was slightly lighter than it had been earlier, not that Adrian would know, he had barely had the chance to look in a mirror.

"Cassie?" He paused at his own voice, it sounded completely different, but not much deeper, his accent (one he hadn't realised he'd had) was gone. He could tell because his pronunciation of 'Cassie' sounded wrong to his own ears, while in fact he was probably saying it 'correctly'. "I feel...different" he said, his words sounded stupid to his own ears, "you look it" Malcolm answered quickly, if unhelpfully. Akana looked as if she had somehow been expecting it, Martha seemed ready to collapse but...Adrian couldn't see their faces, he was too busy watching Cassie.
