I still don't own Doctor Who (in this Universe), any questions?
And before I start talking, here is the chapter.

*Opening scene of Death in Heaven*

She was hiding from the Cyberman when she heard the voice again, the same one that had convinced her to not stop travelling with the Doctor after what was supposed to be their last time and that helped her deal with the Boneless when the Doctor was trapped inside the TARDIS, but it felt different this time somehow.

"Stop. You can't kill me." She said while slowly backing away from the Cyberman that had located her.

"Incorrect" It stated.

"I'm a target of great strategic value. Alive, I'm a tactical advantage. Killing me would be the biggest mistake you ever made. You have no idea of who I am." She said, her hand unconsciously going to her pocket to clutch her old watch.

The Cyberman paused for a moment to scan her before stating "You are Clara Oswald. You are human. You are unimportant."

"That's what you're supposed to think," Clara said, a slight grin forming on her face as she devised a plan even if she wasn't exactly sure of what she was doing "that's what everyone thinks."

"You are Clara Oswald." The Cyberman continued rather stubbornly.

"She was just a cover story, a disguise. There wasn't ever a real Clara Oswald." 'Clara' continued, hoping that she could just convince the Cyberman to leave, even if she knew that it wouldn't be so easy.

"Identify." The Cyberman insisted.

"Don't be so slow, it's really embarassing. Who can fool you like this, hiding right under your nose, changing face any time they want?" She said, backing away from the Cyberman while half-expecting the Doctor to appear at any moment "I'm not Clara Oswald, she hasn't ever really existed."

"Identify." The Cyberman insisted again.

"I'm the Doctor." Clara kept lying, even as a part of her insisted that she wasn't.

"Scans indicate human biology." The Cyberman stated, raising it's arm to fire at her "You will be deleted."

"I'm sorry that it has to be this way Clara." She heard the voice say before she completely lost control of her body.

"Alert. Time Lord consciousness detected. You will identify." It said.

"You really are slow, aren't you? I told you that ages ago. Or did you forget it already?" The Doctor asked, discreetly configuring the sonic that was in her pocket to a frequency that would hopefully deactivate the Cyberman.

She only hoped that she correctly remembered the specific frequency that Missy had used for this Cyber-Cloud.

"Scan indicates a shared consciousness between the Time Lord known as the Doctor and the human known as Clara Oswald." The Cyberman said after scanning her again.

"I always did wonder if you were really this slow or if Missy specifically programmed you that way so that you couldn't harm me. Wouldn't put that beyond her." She said with a smile on her face.

"And you just made the biggest mistake of your life by letting me talk." The Doctor grinned, puling the sonic from her pocket and aiming at the Cyberman, deactivating it in less than a second.

She really needed to get said sonic back to her past self later, but that was somewhat of a secondary concern as she focused on trying to find the exit again.

The Doctor receded back into the watch when they got closer to the door. Clara could go outside and face the Old Man. She really was in no mood to deal with her past self after she nearly exausted herself mentally by taking control of Clara's body.

Clara in the meanwhile felt confused. What exactly had happened there? She had a very vague feeling that she had somehow disabled the Cybermen on the way out, but she had no memory of it.

Her thoughts were suddenly interrupted by the Doctor who came running out of the TARDIS that had been parked right outside.

"Clara, I found out who it was, the woman in the shop who gave you my number. It was..." He said excitedly, barely noticing that she slipped the sonic into his pocket when he got closer.

"Missy. Because I'm the control freak, you're the man that should never be controlled and because you'd go to hell if I asked." Clara whispered sadly, pulling him into a hug and ignoring his response.

"Clara?" He asked, confused by what her words could imply.

"I-It's nothing Doctor." She answered after after a moment "Do you think you could leave me at my flat? I need some time to think about a thing."

"Sure." He said, moving back towards the TARDIS and pushing the confusion towards the back of his mind for the moment. He could solve it later.

*Café Scene at the end of Death in Heaven*

He could sense something was wrong when he entered the cafe, and that sense only intensified when he saw Clara playing with a fob watch.

"Hi Doctor." She said after pocketing the watch when he sat down "I definitely approve of your choice of Osgood as a companion. But then again, I might be biased."

"So you're truly me. I was hoping you weren't." He answered after a few seconds passed "But why?"

"I needed to hide. Didn't have that much time to set the specifics." She stopped to think for a moment "Well, now that I think about it, River was the one closest to the console, so I suppose she could have done something without me noticing it."

"She always did know far more things about us than she ever let go. But why are you here?" He asked.

"I just wanted to say goodbye to you as Clara before..." She stopped for a moment before getting up and moving to besides the table "One last hug?"

"I suppose." He said, slowly putting his arms around her after she had already done so.

"Goodbye then. Try not to regenerate before you're supposed to." Clara said with a smile on her face, which quickly disappeared when she noticed the way he was looking to the nearby alleyway. She didn't need to look because she knew who was there, but she had hoped that Rose would have stayed inside the TARDIS waiting.

Part of the reason she hadn't changed back yet was that she had wanted her younger self to remember traveling with her. It wasn't like knowing it would give him foreknowledge or anything, since all the memories would be trapped inside the watch, and of course, the memories about her being him would be changed (thanks to the TARDIS) into memories of her saying that she wanted to stop traveling with him.

Of course, the mere thought of Rose almost made the smile completely reappear in her face. Almost. Because she knew that now the Old Man would have to forget it, after all she remembered that it had been a complete surprise for her when she ran into Rose while testing the calculations needed to bring Gallifrey back.

"You know that you'll have to forget that she's there, right?" She said sadly.

"Yes." He stated simply, before adding "Does she know?"

"Yes. Took a long while, but yes." She answered.

"Good." He said, smiling slightly. You wouldn't know that the smile was there if you didn't know how to look for it, but it was there. "Goodbye."

He then quickly got into the TARDIS and dematerialized before setting the course for UNIT while his mind already suppressed the memories.

Clara meanwhile walked towards her own TARDIS alongside Rose, neither of them speaking until they were already inside.

"I suppose it's time then?" She asked, a part of her still wanting to delay it.

"Yea." Rose supplied "River already has the coordinates and everything ready in her diary. She assured me that anything after fob watching you wasn't registered there, so it should be safe to pick it up at the Library."

"No sense delaying it further then." Clara whispered before opening the watch. It certainly wasn't as painful as having changed into a human, but it still hurt for a moment.

"Goodbye Clara" The Doctor whispered, pocketing the watch once again and turning to Rose.

"Ready to go Doctor?" Rose asked, and although her voice was calm the Doctor could see that she was worried about her (It must have been because of what she had told her about when Sandshoes had had to become John Smith in order to hide from the Family of Blood).

"Yea." She said, drawing Rose in for a kiss "I'll be fine. Specially now."

And together they set off towards the Library to recover River's diary.

I hadn't really planned doing this. The idea to sort of rewrite the first chapter just appeared and I followed it.
Bye. Might be seeing you again. Or not.
