The penultimate chapter. This is actually going to be the last chapter of the story as I'll use Chapter 13 to show you some of the abandoned concepts. I don't think I need to show you the Doctor revisiting Jackie. I'll leave it to your imaginations. Hope I've done justice to this story. Hope you thoroughly enjoyed it because I have certainly enjoyed writing it and reading your reviews. Thanks Everyone!

Realisation dawned on the Doctor. Of course, his thirteenth self tried to get the Doctor's remaining lives during his trial in his sixth self posing as the Valeyard, and then again as Jack the Ripper during his seventh self.

Only he himself would be able to travel in his own timestream to alter events as he is the only Timelord left alive.

"Shocked to see me?" His thirteenth self said. He was not the prettiest of his incarnations. Some teeth missing and yellow. He looked like he gets stoned every night.

Gone was the patriarchal dignity of the First Doctor, the puckish charm of the Second, the dashing elegance of the Third. No trace remained of the easy-going bohemianism of the Fourth Doctor, or the gentle dignity of the Fifth, or the stubbornness of the sixth. The sweet old man that was the seventh did not remain in this incarnation, or snobbishness of the eighth, or the eccentricity of the ninth. Nothing remained of the charm of the tenth, or the way his eleventh self was so laid back. This Doctor was a monster.

"Why did you do it?" The Ninth Doctor asked. He could feel the time vortex working his way through him. He will soon regenerate.

" I gave up on trying to gain your remaining lives as I had little success. So I had a change of plan. I'd try and extend your lives but causing plenty of misery in the process. I'd go back and change a few details so that you can become more of a monster.

You did most of the work for me by visiting your first self. That was a stroke of genius I might add. Of course because of you then, the Second Doctor never called the Time Lords to help in the War Games and cost the lives of Jamie and Zoe. Of course they weren't the only ones to die. Katrina still died, but along with her a lot more people died. Jo Grant, Sarah Jane Smith and Liz Shaw." The Valeyard said while grinning.

"I had visited your fifth self before you even went to visit your first and told him that he must take the antidote instead of giving it to Peri. I told him if he doesn't the Timelords will all die. He believed me as he knew I was him." The Valeyard said.

The Doctor took this all in. The Valeyard went back to his ninth self and made sure he never kissed Rose therefore he did not regenerate hence the reason he went back a regeneration.

The Fifth Doctor was the same. He made sure he never gave the antidote to Peri therefore another regeneration was missing, so again he regenerated back one.

He himself had caused the third regeneration backwards by just visiting his first self. He should have blocked his mind in the first place to avoid this mess. His first self made sure his second and third self avoided regeneration, but it still came to them eventually.

"Well I sorted out that little problem. I interfered and gave the antidote to Peri as she should have had it in the first place, and now I've kissed Rose." The Doctor said while trying to find a weapon. He will destroy this beast once and for all.

"It is useful having a time travelling machine to visit certain points in history and evaluate the WHAT IFS in history. What if I let Rose die and you prosper? What if I let Peri die instead of giving her the antidote? What would happen if I help the Daleks to survive the Time War?" The Valeyard said.

The look on the Doctor's face was priceless. It was a look of surprise and hatred. His people had died to bring an end to the most monstrous race ever to crawl in the universe, and he, the Doctor, had helped them to survive. His mortal enemies survived because of this monster. The Doctor put his hands in his pockets and felt the sonic screwdriver. He was very grateful he had made a bomb during his stay. It would not cause great damage, but enough for the Doctor and Rose to escape.

"No. Your plan has failed." The Doctor said, painfully, as the time vortex was reaching its climax.

"How exactly?" The thirteenth Doctor said, while still grinning,

"I sent a little note to myself to block my mind against my first self. Jo Grant, Liz Shaw and Sarah Jane Smith survived. The spiders never took over the country. I sorted out my fifth self. I've sorted out this. Everything has gone back to as it was." The Doctor said.

The Valeyard laughed."I can just keep going back and altering it again and again and again. There is no stopping me." The Valeyard said.

"Oh yes there is. You see, I came across a TARDIS which did not belong to me. It was very mistreated. So I sent it away to die peacefully, away from your evil grasp." The Doctor said.

The Valeyard burst out laughing.

"So what? I will still find a way off here. Besides, the TARDIS you know died a long time ago. That one, is the only other TARDIS in existence. I found her on my travels, and befriended her, then ensnared her. It took time and effort but I eventually took control of her. I made her change into a Blue Box. Compassion, Doctor, all you need is Compassion." The Valeyard said.

Again, the Doctor's face was a picture. His memories floated back to his eighth self, when Romana had tricked his companion Compassion, and she turned her into a TARDIS to help fight the Time War. Compassion survived, and carried Fitz and the Doctor away.

"How dare you?" The Doctor said, and flicked the switch on the screwdriver. Explosion directly in front of the Valeyard. The Valeyard fell over cursing and screaming as it had temporarily blinded him

The Doctor picked up Rose and moved towards the TARDIS Rose had come in. He was getting pretty tired over trying to open the TARDIS door while holding unconscious women. Rose was waking up and looking up at the Doctor.

"What happened?" She asked as they entered the TARDIS.

"Nothing really." The Doctor said and put her down. He winced.

"What's wrong?" Rose asked.

"The Time Vortex went into me. Our people have this neat trick of cheating death. It will mean I'll change though." The Doctor said, "I was going to take you to so many places Rose. I was going to take you to see Barcelona. Not the city, the planet."

"Doctor." Rose said, looking extremely worried.

"Before I go, I just want to tell you, you were great. Hell, I was great." The Doctor said and grinned. Bright flames erupted from the Doctor, and there stood a completely different Doctor.

"New teeth." The doctor said to a bemused Rose. She was speechless. It's not everyday you come across a time travelling alien who can just so happen to change appearance. In all her travels with the Doctor, what she had just witnessed was by far the weirdest thing she had ever seen.

"So, Barcelona!" The Doctor said and grinned. It looked too much like his old self.

"You act as if this is normal," Rose said, weary of this new person in her life.

"It is. For a timelord anyway. That was my ninth regeneration. I'm in my tenth self now." The Doctor said. Rose still looked lost. She has had one hell of a day. What with almost being obliterated on the Weakest Link, destroying the entire Dalek fleet of about 500,000, almost dying and the doctor regenerating, it's a wonder she'll get over this.

"You should have seen some of my regenerations. The process is not pleasant at all. I promised Jackie I would let you visit her. Let's go." The tenth Doctor said.

"How did you promise her? When?" Rose asked.

The Doctor paused and grinned.

"Long story. I'll tell you about it some time." The Doctor said. He flicked the switches on the TARDIS and away they go.

The Valeyard was still screamin as the TARDIS was leaving. His sight was coming back slowly but many things were still a bit blurry..

I'm going to kill him, The Doctor thought. He was marooned on this satellite with no way of getting off. Compassion was gone and he'll never find her again.

He could hear footsteps running towards him.

A young man came running into the room wearing tight black leather trousers and a white top. He looked gutted as he saw the TARDIS leaving.

Captain Jack.

Human from the 51st Century.

Ex-Time Agent.

Knows a lot about Time Travel, The Valeyard thought and grinned wickedly.

I believe I can turn this situation to my advantage, the Valeyard thought. They were both stranded on this station and both had much knowledge about Time Travel.

The Valeyard made his way towards Jack. He would keep his identity a secret, make sure they both help each other, then ditch him the first chance he gets. It will be a change to actually have a human companion again.

The Valeyard would get his revenge and the Doctor's final lives.

He will.
