A/N: I know, I know, it's been ages since I was here last. I am still struggling through with my other Doctor story. Hopefully when I next look at it I'll be more inspired now I've had a new Doctor fix! So anyway. Here is the newest filler, don't read if you haven't watched the episode. (FAB episode. David's acting; even more brilliant than usual!!) Well here it is. I would say enjoy but you know it's not going to be a happy one.

Waters of Mars

"For a long time now, I thought I was just a survivor. But I'm not....I'm a winner, that's who I am. The Time Lord Victorious."

"But that's what you do. You're the Doctor. You save people"

"Not this time. Pompeii is a fixed point in history. What happens, happens. There's no stopping it."
"Says who?"
"says me."
"What, and you're in charge?"
"TARDIS, Time Lord yeah!"

"The universe has to move forward. Pain and loss, they define us as much as happiness or love. Whether it's a world, or a relationship... Everything has its time. And everything ends."

"Doctor, you can stop now,"

"It's not the one pointing the gun at me."

"I think sometimes you need someone to stop you."

"Look around you! Nothing but death and destruction!"

"I'm telling you right now. I am NOT having ONE more dead. You got that? Not ONE!"

"What about you, Doctor? What the hell are you changing into?"

"Your song is ending Sir. It is returning, it is returning through the dark. And then, Doctor... Oh but then, he will knock four times."

They'd all seen it. They'd all seen what he was capable of, but they'd stopped him going over the edge. Why couldn't he stop himself this time? He knew that he was meant to keep the timeline in tact, not meant to interfere with fixed points in time. Hadn't he told Rose the same thing when she'd saved her father? What was the point in following the fundamental rules all this time? He knew they'd been created for a reason back back on Mars he'd lost sight of the bigger picture. Why had their panic got to him? He heard peopl's last wods everyday, they were always in his minf, always speaking to him. Why was today any different?

Because the bell is tolling!

Why was the impending regeneration affecting him so? He'd done it so many times before.

Because you're alone. There's no one to stop you, no one to talk to and no one to care!

The last time he;d regenerated Rose had been there, disbelieveing at first but she'd been there. But he'd liked being Doctor Mark 10. Doctor 10 had had Donna, Martha and Rose. He'd fallen in love; something he'd never thought he was capable of. He'd had his heart broken, and not just romantically. When he thought of it that way, he shold be gland an end was on the horizon, he should hope that his hurt wouldn;t follow him to his eleventh.

Rose, Donna,Sarah-Jane, Martha, even Jack. They would all be so ashamed of him, he'd done the one thing he'd vowed bever to do. Never change a set event. And when had he decided that any human was a "little person"? When had any human being become any less important than another. It was those "Little People" that made the great things happen.

He shuddered when he realised how much he sounded like the Master. He'd enjoyed those few moments of darkness that had clouded his mind, enjoyed defying those he'd run from all those centuries ago. He'd run away from the Time Lords so that he wouldn't become them - vengeful, self-important, lording it over the universe. Deciding who could go where or when. In those moments on the idyllic, snow covered London street, he'd become one of them.

But would having someone beside him have changed anything? He thought back to Pompeii and how Donna had begged him to save people. He did it.

Sarah-Jane had reminded him that bringing back his people by joining with the Krillitane had been a bad idea. "Everything has it's time"

Would any of them have stopped him on Mars?

Rose?

Rose had saved the life of her father and had seen what could happen if you changed history - but what about the future? Would his warnings have applied? Would she have kicked up a fuss and been able to talk him round? Probably not.

Jack?

Jack was the man who'd been there and back again. He'd seen the future and the past. He understood how the universe worked. Yes, Jack could possibly have stopped him - he could have dragged him back to the TARDIS kicking and screaming if necessary. What ever the Torchwood boss would have done, however he'd have dealt with it, he'd have seen the bigger picture. Jack would have made the Doctor do the right thing, even if it meant inflicting harm on him, he would never have let him win.

A thought struck him. Had anyone else commited suicide after meeting him? After being 'saved' by him? Sarah-Jane had waited for him, most seemed to have carried on with their lives, but he'd never checked on them, he never even thought of most ever again.

Martha's mother was right. Death followed in his footsteps, and soon he and Death would be neck and neck. He didn't know when or how or who. All he knew was that he would knock four times and there was no way of fighting it. No defence against the unknown. His time as his Tenth self was coming to and end - and what a time it had been! What a life he'd had. He'd have to write down all the things he didn't want to forget; the people who had shared time with him, those he'd laughed and run with, those he'd been terrified with. those he'd love and lost. Those who'd been scared of him and those who'd looked after him. Yes, if Ten's life was coming to an end he wanted to be sure Eleven remembered. There was no telling with regeneration and this time he'd have no friends to remind him.

His hearts clenched at that thought and he wondered which was worse; dying or dying alone? At least alone he couldnt hurt them and they couldn't hurt him. Hadn't he told Jackson Lane that he was better alone because his companions always break his heart? He thought about the last few months since losing Rose again and having to destroy Donna's memories. Martha and Donna had bridged the gap left by Rose; it was too deep to fill but they had made it bareable. Now there was just a gaping hole that had grown.

With death looming he was falling apart, he was making mistakes and letting his fear rule him. He needed help but had no one to turn to. He laughed ruefully. All the thousands or millions of people he had met and saved over the centuries and he had no one, not even a hand to hold. But that was as it should be wasn't it? They deserved better than a war-weary lone Time Lord. He hoped they were all happy, and content. Wished them every good thing, and most of all he never wanted them to turn out like him.

He had to remember that he had been loved and still was and that death wasn't the end; not yet. He had a while to go before that, if he bothered to regenerate.

A/N: Told you it wasn't happy. A nice dose of dark Doctor for you. So, until Christmas that's it for the fillers. Let me know what you think?
