Hello everyone! Welcome to our lovely collab fic. I'm Rhia and sitting in the virtual armchair next to me is Mandy, who says hello as well. Here on FFNet we go by –Rhiannon –Onyx Moon and phantomforever42. (And no, Rhia isn't my real name. *winks*)

This is my first time writing for this fandom, but Mandy does it all the time so hopefully people won't eat us. Kidding! Kidding! *holds up hands* You're all too nice for that~

So anyway, we don't own Doctor Who and all that. Although I do own a sonic screwdriver. And a bow tie. And seasons two through five of New Who. And Mandy owns a TARDIS mug and a t-shirt that says 'waiting for a mad man with a box.' (And she's made two Dalek birthday cakes to date.)

Oh, wait, you wanted warnings? Oh yeah! We have watched a few episodes of old!Who (together) and tend to reference them occasionally. It's not really important to have watched the episodes though.

We're (well, Rhia is anyway. Mandy is somewhat) obsessed with anime, too, and Rhia has a tendency to make the Master tsundere. And occasionally moe. Actually, she makes almost everyone moe at times. And, um, if you don't know what those mean… go look them up?

^-^ And enjoy!

The Doctor closed his eyes tightly and prepared to meet the inevitable end as the Pandorica hurtled towards his exploding TARDIS. He realized that his ship must have been in terrible pain and felt a pang for her even as he was flung into the explosion she had caused.

He gritted his teeth as he felt the Pandorica enter the heart of the TARDIS, felt it explode, felt himself hurtling forward. Goodbye, he thought, but who he was saying this to, he could not have told you.

XxXxXxXx

He woke several seconds later on the floor of the TARDIS.

"So, I escaped then. Love it when I do that," he said, looking around. He was in his TARDIS but it was a memory from weeks ago, when he took Amy to Space Florida. It was a living, breathing memory that he was standing and watching.

Slowly, he began to realize that he was rewinding through his life, unseen but hearable. First, he shouted to Amy, trying desperately to make her hear him, hoping to hang onto his life as it was now but she never realized whose voice it was that kept saying her name.

The Doctor felt Time slipping through his fingers and his life literally flashed before his eyes as he went back to the night of his regeneration, the night his faithful Amy had waited. He bid Amelia goodbye.

He would miss his mad, impossible Amy Pond; partner in crime and crime-fighting, his best friend, the girl who had saved him in so many ways.

He felt himself rewinding again and saw himself saying goodbye to Rose one last time. The Doctor felt a twinge of sorrow as he watched her run up the stairs and away from his former self. He would miss Rose as well, although his regeneration had given him a sense of distance from the pain his tenth self had felt at losing the blonde girl.

The rewind began again and he found himself in the room with the glass roof, watching his tenth regeneration point a gun at the Master. "Get out of the way," he heard himself say. A grin spread across the Master's face and he moved away.

Time seemed literally to slow for a minute. The Time Lock opened and he could see the Master push him out of the way. For once, the Doctor acted impulsively; in the confusion as the Master began to fall into the Time Lock, he ran forward, grabbing the Master around the middle and pulling him out of the way.

He pushed and pulled the Master (who appeared to be unconscious, having expended nearly all of his remaining life force pushing Rassilon back into the Time War) into the isolation chamber, releasing Wilf. A light flashed round the room as the Time Lock closed and he held onto the Master tightly, hoping it wasn't too late to save him.

The Time Lock closed with a blinding flash and as the noise faded, the Doctor could hear the yells and cheers coming from outside the building. "That great, bloody planet," he could hear a man's voice shout, "it's just gone!"

The eleventh Doctor felt his timeline twist and bend, new memories forcing their way into his mind. The Master and his tenth self, laughing, running, shouting, fighting and - Oh. The Doctor smiled. He looked forward to it. Er, backward.

He looked over to see his former self, on his hands and knees, coughing and choking out, "I'm alive, I'm still alive." The Doctor clambered to his feet and tapped on the glass wall of the chamber, four times. The tenth Doctor turned, eyes slightly unfocused, to where Eleven and the Master were trapped in the isolation chamber.

"What?" the older man (wellll, technically younger. But not physically, just in terms of memory) said, bewildered. "Please," Eleven almost begged, remembering that he couldn't be seen. "Get him out, help him or he's going to die soon, his life force is burning up quickly."

The tenth Doctor looked confused for a moment before his eyes focused on the Master, lying unconscious on the floor of the isolation chamber and the readings on the machines next to it. Realizing that the chamber was about to flood with radiation, he pushed himself to his feet and almost ran into the chamber, pressing the button to release the Master and (though he didn't know this) his future self.

Eleven reflected on how he hadn't even given a second thought to the danger he had been in, driven only by his need to save the one person he had left. He pulled the unconscious man out of the chamber. He watched himself writhe in pain as he absorbed the radiation, horrified but now knowing exactly what to do.

He gently laid the Master on the floor just a few feet from the isolation chamber and walked over to the crack in the corner of the room that he hadn't noticed (or had passed off as another byproduct of the sound beating that the mansion had taken) in his previous regeneration.

He let the crack open up and he stepped inside. Alone with his memories for all eternity? That would be torture to anyone but the Doctor because no one had memories quite like his.

He thought of Rose, the Bad Wolf, who he had lost to the void and then to himself.

He remembered Martha, the doctor who healed the world with a single word and Donna, the temp who became so much more.

He remembered Jack Harkness, the face of Boe and the Casanova of the 51st century. (Hang on, hadn't he been with the Time Agency? And hadn't portraits of Casanova looked suspiciously like one Captain Jack Harkness? ...Oh dear...)

He thought of River Song, the woman who studied the past but knew his future, Amy and Rory, the ones who waited and the Master, whose time with him was happening, was about to happen and had already happened.

The eleventh Doctor stood in the darkness of the void, remembering, and then heard a voice say, "Something old, something new, something borrowed and something blue." He smiled. Well, maybe there were more memories to make yet.

XxXxXxXx

The tenth Doctor stood and staggered out of his side of the isolation chamber, feeling the regeneration energy starting to flow through his body, warm and healing. He saw the Master and, realizing once again what was happening, swept him up into his arms honeymoon-style and almost ran to the place where he had left the TARDIS.

He pulled out his sonic screwdriver and synced the TARDIS with his timestream again, snapping his fingers to open the door and dragging the Master inside. He carried the Master up the stairs, nearly to the console before his legs gave out and he dropped to his knees.

The Doctor somehow managed to push the Master away before the energy flooded through him, bursting out of his skin as his body healed and almost began to change... Through the fire in his brain he could hear only one thought.

Have to... save... him... Without quite knowing why he was doing it, he turned in the direction of the Master and let the energy flow out of him and into his dying friend. He gasped and looked down at his hands. They were the same as ever. He found the nearest reflective surface and saw the same spiky hair, same wide brown eyes.

Now that the energy had stopped blazing through him, almost stopping all coherent thought, he began to regain a sense of self and to remember what was happening to the pair of them.

He watched as the regeneration energy healed his old friend, watched life come back into his face. The Master's eyes opened and he saw the confusion and fright in them. The Doctor put a hand gently on the Master's face. "It's - it's fine, everything's alright," he murmured, slurring slightly in his exhaustion.

The Master's face filled with relief for just a second as he saw the Doctor then his walls were back up and his face was guarded as he sat up to look around. "We're in the TARDIS," he said, confusion coloring his voice."What happened?"

The Doctor was almost ready to collapse but he managed to gesture to himself and then to the Master and say, softly, "You saved me... I saved you... Guess we're even now."

Then he laid his head down on the cold metal grating and closed his eyes. The Master was almost speechless for once, merely placing his hand over the Doctor's and holding it to his own face. "Thank you," he whispered, once he was sure the Doctor was really asleep.

"Thank you."

Hello! Mandy here. Just wanted to let you know that Eleven is just waiting longer for his regeneration and his timeline is the same as it is in canon. Also, we'll be updating every two weeks (or sooner, depending on when we get the chapters finished) on Saturday.

Thanks for reading.
