AN: This is it, the last chapter currently written. I hope to start posting another cross-over fanfic soon (same universes, except without the Good Omens crossover ;)) so keep an eye out for that. And again, if you have any ideas for where Harry and the Doctor could go next, let me know!

**HPBB***

When Harry came back to himself, it was to the same sight that Ulrir had shown him. He'd be glad enough when this was all over, if only because then he'd be the only one left in his own mind. Right now it was a tiny bit crowded, what with the Anomaly, the golden net, Aziraphale and Crowley on either side of him and the Doctor behind him.

"Right. Angel, I think you'd better take over protection detail. Something tells me I had better not touch that net, it might take exception to my being a demon. I'll take the Anomaly. Doctor, take care of Harry, it's his mind we're inside of."

With that, Crowley and Aziraphale moved closer and snapped their fingers at the same time. For a moment, nothing happened, but then both the golden net and the darkness inside it flowed apart and formed again. The net became a beautiful young woman with auburn hair and green eyes. The Anomaly became a man, robed in black, taller even than the Doctor, with a bald head and slits for a nose.

Crowley pulled a sour face at the sight. "I'm all for snake attributes, but that is just tacky!"

"Finally!" the snake-man hissed. Harry wasn't quite sure how he managed to hiss a word without an s-sound in it, but there it was. "I could have possessed the boy ages ago if it wasn't for that wretched woman! Who do I have to thank for getting rid of her?"

"'That wretched woman' is right here and not going anywhere as long as you're anywhere near my son, you leech!" The woman had stepped forward, next to the Doctor, shielding Harry from the Anomaly's gaze.

The Doctor, standing with his hands in his pockets, cast her a sideways glance, but evidently decided to just go with it (which, admittedly, he had a fair bit of practice with).

"Yeah, what she said," he added. "Also, most of us here take umbrage at the whole possessing innocent people thing, so... The only reason we interfered in an otherwise excellent setup – congratulations for that, by the way," he said aside to the woman, "is to get rid of you."

The man regarded the Doctor with some curiosity. "You would think it easy getting rid of me? I am the greatest wizard of all time! I am Lord Voldemort! After I have taken care of you and your little friends, I will have a body again, and all will learn to fear my name once more!"

"Eh," was the Doctor's bored response as he scrunched up his nose a little. "You're not nearly as impressive as you think you are. My new friends here have seen all manner of earthly civilisations rise and fall. I've seen the birth of this planet and its destruction. You... blew up some people and then got done in by a baby. Not a great track record."

"Also," Crowley added, "Voldemort? Really? Kind of a stupid name, isn't it? Doesn't even make any sense!"

Harry had the impression that Voldemort was seconds away from stomping his food, much like Dudley did if he didn't immediately get what he wanted.

"It means Flight from Death!"

"Oh no, my dear. It really doesn't." That was Aziraphale, who felt that if they were going to insult the person who was so impolite as to try and possess a child, he wanted to add his two cents. "What it actually means is corpse theft. Or, you know, corpse flight, as in a flying corpse, not a fleeing corpse. Sorry, old chap, looks like you didn't quite think your name through. Or your French is a bit more lacking than you thought. Take your pick."

"Enough! This ends now!"

Voldemort raised a hand holding a long white stick, and so did the auburn-haired woman, whom Harry thought must be his mother, although hers was brown rather than white. The other three readied themselves, even if they had no visible weapon. None of them needed it.

From Voldemort's stick erupted different coloured lights, but when they impacted on anybody, nothing happened. Voldemort's face contorted into a furious mask.

"You're forgetting something, Voldy-boy," said the Doctor, who had not moved from his place. "You're not in the real world, or even inside your own mind. You're inside Harry's. Not only do you have to imagine the damage you want to do, but you have to compete with his imagination. I can tell you, nobody has a better imagination than children, and you... you've stagnated."

"It's more than that, though," Crowley said. "You're not a complete soul, you're more like half a soul. Not even that, you're..." he frowned, the corners of his mouth turning down in surprise. "What, what do you say Angel, one sixty-fourth of a soul, more or less? How did you manage that? You're tiny! Insignificant!"

Even as Harry heard the words, the man seemed to shrink as his mind translated Crowley's words into what passed for reality here.

"No!" Voldemort screamed. "If I can't have the boy, at least I'll take down the mudblood!"

He made to move towards the woman, but Harry wasn't having it. They'd thought something like this might happen, even if they hadn't quite counted on the extra bodies.

Grabbing hold of two hands, one the Doctor's and the other his mother's, he glared at the now much smaller snake-man. In a voice that wouldn't truly be his until many more years had passed, he growled. "No. Get out of my head. You are unwelcome. I reject you. My body is my own, and you will not have it."

The last words were hissed in a language that Voldemort knew well. With all his might, backed by the strength of a mother, a Time Lord, an angel and a demon, he pushed and pushed, until finally, with a last defiant 'No!', the presence faded from his mind. At the same time Crowley and the Doctor departed as well, somewhat more of their own volition.

Aziraphale lingered a moment longer.

"I can give you two a while together, but then I will have to help you move on," he told the woman. "But well done, child. Very well done indeed."

And he too stepped out of Harry's mind, leaving him face to face with the soul of his mother.

"Hello, love," she said softly, before he could decide what to say. He studied the auburn hair, the open face, and the green eyes that looked so much like his own.

"Are you real?" he asked hesitantly.

She reached out a hand and cupped his cheek. "For now," she answered sadly. "There's not a lot of time, and once I'm gone you won't be able to talk to me like this anymore. I gave up my chance to move on when I cast that protection spell on you. I didn't know I'd have to keep protecting you against possession."

"I'm sorry," Harry said in a small voice, sounding much more his age than moments ago when he expelled Voldemort.

"Oh no, baby. Don't be. I would do it a thousand times over if it meant I would keep you safe. You didn't do anything wrong. You're my son, and I love you. I want you to live the best life you can. Never forget that. It's not your fault, none of it. Now come here, give me a hug. It's nearly time to go. We had better make it a good one."

Harry's eyes filled with tears as he felt his mother's arms surround him.

"I don't want you to go!" he sobbed.

"I know, honey. I wish I didn't have to go too, but there's no other way. Wherever I'm going, I'll be watching over you. Always remember that we love you, your father and I. We will always want you to be happy, Harry. You deserve it."

They clung to each other a while longer, until he realised he was no longer hugging her. When he opened his eyes, his cheeks wet with tears, he was back in the real world. The Doctor was sitting on one knee, looking relieved when he stirred.

"Alright?" he asked, peering into his eyes.

Harry shrugged, unsure how to answer. "Been better," he answered. "Tired."

"Yes, I can imagine. We'll go back to the TARDIS soon, then you can sleep it off. We can talk more when you're not half dead on your feet."

With the Doctor's help, Harry stood up, although he was swaying on his feet.

Crowley was sitting sprawled on Aziraphale's sofa, studying a vial he was holding in his hand, filled with black smoke.

"What's that?" Harry asked.

Crowley looked up at him. "That, kid, is the leech you had inside of that scar. I'm gonna keep hold of this for now. Do me a favour though – if you find any other missing bits of soul lying around, send them on to me. The higher-ups would laugh in my face if I tried to bring in a titchy part of a soul like this one. Ugh, the paperwork that would entail!" The demon shuddered.

"Just be careful, dear," Aziraphale added. "This was only a tiny soul part, hardly even human anymore. Voldemort must have split his soul at least six time for it to become so small. Any other soul parts are likely to be stronger, so if you can avoid confronting them directly that would be best, and if there's no way to avoid it, make sure you have back-up, ok?

The Doctor frowned.

"You talk as if it's a certainty he'll encounter more of these soul pieces," he said.

Crowley stood up and slung an arm over the Doctor's shoulder.

"He had one of them in his head, Doctor. Be honest, from your own experience, and knowing there are more of them out there... is there -any- way he would NOT meet more of them?"

The Doctor grumbled. "I guess not. Ugh. Well, at least we can fortify his mind a bit, just in case another one tries to take over his mind. In any case, thank you, both of you, for your help."

He looked down to where Harry was leaning heavily against him with drooping head, too tired to pay attention to the conversation.

"Anyway, I had better get him to bed, he's knackered. But if you don't mind, I should like to visit again later. I don't often meet beings as long-lived as yourselves, on earth at least."

Aziraphale inclined his head, while Crowley grinned. "Sure thing, Doctor. I think we have more in common than I thought at first – you know, other than our face."

The Doctor winked back at him and then looked down at Harry. He didn't think the boy would manage the short walk to where the TARDIS was parked.

"C'mon, Harry, up you get. I've got you."

He took the nearly sleeping boy in his arms and smiled slightly when he felt him snuggle deeper. Time for a much-needed park in the Vortex, to give Harry time to heal.
