AN: This is my first ever fanfiction. I'm writing it for fun, but writing is a hobby and something I would like to do for real. So I thought I'd practice writing fanfics. If you like this story, brilliant. If you don't then stop reading it, simple. Reviews are appreciated, but be warned I will ignore you if it's rude or insulting. I apologise for any spelling or grammar mistakes. If you see any please let me know and i will correct them. Thank you.

If you're a Rose fan and don't like her being bashed. Then this story isn't for you. But for future reference i will eventually write one with her being bashed. I used to like Rose, but the she just changed in season two. She just went downhill and I didn't like how she treated certain people or handled certain situations.

This story will be slightly AU at times and there will be an original chapter because i haven't written the Love and Monsters episode and I apologise if any of the characters turn to OOC, I'm still getting the hang of things.

I don't own Harry Potter or Doctor Who.

Prologue – Father's Day

8 year old Hermione Granger was sat in the back of her parent's car with her Aunt and baby cousin. They were on the way to a friend of her mother's and Aunts wedding. She didn't really want to be there, she would have preferred staying at home in her room reading. But she had to be there, she was just happy her best friend Mickey was going to be there. He was the only one who treated her normally. He didn't find the weird things she could do as freakish, he found them amazing and always asked her to show him more.

The car pulled up to the church and Hermione waited for her dad to open the car door so she could get out. She knew she could do it herself, but she's not allowed to do the weird things today. Once she was out she smiled at her Aunt Sarah, who was her mother's friend.

"I'm here, stop your belly-aching. Take Rose a sec, will ya?" Jackie said as she stood behind Hermione. She handed her friend Bev a carry-tot, with Hermione's cousin Rose inside.

"Oh, in't she pretty? You to Hermione." Bev said.

"She's a little madam, that's what she is." Jackie said as she made her way to the church gate with Bev and Hermione's parents. "Oh, I need more hands. Where's her useless article of a dad got to?" Jackie then turned to her sister-in-law "Where's that brother of yours?"

"Who knows?" Jean Granger replied "Maybe he's come up with a new invention."

Hermione smiled at that, she liked it when her Uncle Pete came up with inventions. He always showed her what he had managed to make and how he did it. She smiled wider when she saw her Uncle's car pull up. She turned round and tapped her Aunt Jackie and pointed to the car with a smile.

"He's here." Jackie said and started to head towards him with Hermione running after her. "Oh, wonderful. Here he is, the accident waiting to happen. You'd be late for your own funeral and it nearly was!" Jackie was glad Hermione missed the car nearly hitting Pete.

"Uncle Pete!" Hermione exclaimed and Pete grinned picking her up.

"No damage done." Pete said as he tickled Hermione making her giggle before he placed her back down. Hermione glanced at the blonde girl beside her Uncle and frowned at the nasty look she was receiving. She wasn't stupid she knew what the girl was feeling by the look she was jealous, but Hermione didn't know why.

Jackie looked disdainfully at the blond girl stood with her husband and didn't appreciate the look she was sending her niece "And who's this?" the girl just simply stared at her. "What're you looking at with your mouth open?"

"Your hair." The girl said.

"What?!"

"I've never seen it like..." Jackie stared at her, looking both confused and insulted. "I mean...its lovely, your hair's lovely. And that baby you're holding..." the girl said looking at baby Rose. Jackie glanced at Pete, holding the baby to her protectively, completely nonplussed, and also pulling Hermione close to her. "That would be...your baby..."

"Another one of yours, is she?" Jackie said to Pete.

"She saved my life!" Pete exclaimed.

"Oh, that's a new one! What was it last time?" Jackie started. Hermione slowly pulled away from her Aunt, remembering her mum said about if Aunt Jackie and Uncle Pete started arguing to go somewhere else. Which is what she did, she walked towards her mum and dad who were stood talking to her Aunt Sarah.

"Who's that with your Uncle Pete Sweetheart?" her mum asked her.

"Dunno." Hermione answered. Hermione's gaze was pulled to her best friend running towards her.

"Monsters! Coming to eat us!" Mickey said as he grabbed Hermione's hand wanting to save his best friend.

"What sort of monsters, sweetheart? Is it aliens?" a woman asked as she laughed with her friends. Mickey just ignored everyone wanting to get his friend safe and dragged her into the church.

"Mickey? What's wrong?" Hermione asked frowning.

"Monsters!" was all he said before people came into the church screaming. Hermione watched shadows pass the window as a strange man started speaking.

"They can't get in. Old windows and doors, okay. The older something is, the stronger it is. What else?" Hermione jumped at the screech that she heard "Go and check the other doors! Move!" He ran and pushed against a wooden door in the side of the church.

Hermione made her way over to her parents and Uncle Pete as her Aunt Jackie went to talk to the man. She stared down at baby Rose and covered her more with the blanket she had.

"Don't worry Rose, you'll be okay. Daddy and Uncle Pete will look after you." Hermione told the baby and grabbed her hand.

Rose watched Hermione with baby her. She felt bad for the look she had sent her when her dad had picked Hermione up. It hurt to know that her cousin Hermione had spent so much time with her dad and she had literally none. But she remembered the stories that Hermione told her and now she couldn't wait to be raised by the Pete Tyler her cousin had told her about.

The call of "But someone must call the police!" brought everyone's attention to the strange man.

"Police can't help you now. No-one can." The man said "Nothing in this Universe can harm those things. Time's been damaged and they've come to sterilise the wound." Hermione watched as the man looked to the blonde woman near her Uncle Pete "By consuming everything in sight."

"Is this because..." the girl said shakily. The man just looked at her "Is this my fault?" she received no answer, only a look.

Hermione frowned at the girl and tugged her sleeve to get her attention "Uncle Pete and Dad will keep you safe too." She said before she walked over to Mickey to make sure her friend was okay.

oOo

Hermione was still sat with Mickey when she gathered the courage to talk to the strange man. She walked over to him when he had finished speaking with her Aunt Sarah and Uncle Stuart. She tugged at his jacket and smiled politely when he looked down at her.

"My names Hermione Jean Granger." She said.

"Hello, Hermione Jean Granger." The man smiled "I'm the Doctor."

"Is this my fault?"

The Doctor frowned as he bent down to her level "Why would you think that?"

Hermione looked to see where her parents were before she turned back to the man "I can do weird things." She whispered to him.

"Oh? Like what?" he whispered back.

"I can make my teddy dance by itself. Make the books on the highest shelve float down to me and change the colours of things. I can sometimes disappear and reappear and throw people away when I'm angry."

The Doctor frowned thinking if he had heard of this before. Then he smiled, she was a witch. He had met a few before when the TARDIS had landed in a magical alley. He was lucky that the magic in these witches and wizards were similar to the Eye of Harmony. "No little one, this isn't your fault."

Hermione beamed and watched as the Doctor continued to make the church safe. "Do you need help?"

"Can you make sure that door over there is locked." He asked her with a smile.

Hermione nodded before she ran to the door and tried the handle to open it. When she was happy it wouldn't open she returned to the Doctor to see her Aunt Jackie talking to him.

"Hermione." Jackie breathed in relief, she couldn't find the girl with Mickey and had worried. "Will you stay with this man and Rose?"

"Yes, Aunt Jackie." Hermione replied. Jackie smiled before leaving to find her sister-in-law and Mickey.

"So your Rose's cousin?" the Doctor asked as he stared down at baby Rose.

"Yeah, my Uncle Pete is Mummy's big brother." Hermione said as she checked on Rose. They were quiet for a while before Hermione decided to try and make friends with the nice and interesting man "Do you like reading?" she asked.

"Yes I do. I have a library filled with books." He replied.

Hermione's eyes widened with glee "Really? I'm reading big girl books now."

"You must be really smart then."

Hermione nodded with a smile "Will you be my new friend?"

"Why not?" the doctor smiled.

"You can't be my best friend though, that's Mickey." She said.

The Doctor just rolled his eyes wondering how the idiot made friends with this smart girl before he looked down at baby Rose again "Now, Rose...you're not gonna bring about the end of the world, are you?" he looked at the baby sternly making Hermione giggle "Are you?"

The blonde girl from before came up next to Hermione and smiled "Your friend Mickey is looking for you." She told Hermione.

"Okay." She smiled and waved bye to the Doctor before she went to find Mickey. She smiled more when she saw her Uncle Pete. "Uncle Pete!" she exclaimed as she ran up to him. "I made a new friend and helped to make sure everyone was safe." She smiled.

"Well that's my brave Hermione." Pete smiled.

Hermione waved at him before she moved over to Mickey and told him about her new friend and how she helped keep people safe. Her attention was pulled when she saw the Doctor stood at the front of the church.

The Doctor held up a key "The inside of my ship was thrown out of a wound but we can use this to bring it back. And once I've got my ship back, then I can mend everything. Now, I just need a bit of power. Has anybody got a battery?"

"This one big enough?" Hermione's Uncle Stuart asked as he held up his dad's phone.

"Fantastic." The Doctor grinned.

"Good old dad." Stuart said as he handed the phone to the Doctor "There you go."

"Just need to do a bit of charging up..." Hermione looked curiously at the strange device the Doctor pressed to the phone "And then we can bring everyone back." He glanced around the church as he charges the battery up. He smiled when Hermione waved at him from where she was sat with Mickey.

Hermione watched as the Doctor held the key up in thin air before it stayed in place. It was like he could do what she could. She watched as a blue police box started to appear in front of the Doctor. "Right, no-one touches that key. Have you got that? Don't touch it. Anyone touches that key, it'll be, well, zap. Just leave it be and everything will be fine. We'll get out of here. All of us. Stuart, Sarah, you're gonna get married, just like I said." He grinned encouragingly at them.

Hermione got up and walked over to him "What is it?" she asked looking at the box.

"She's the TARDIS." He said before he grabbed her hand and handed her over to the woman who she looked exactly like before he headed to the back of the church and Rose.

oOo

Hermione sat sobbing as she remember what had just happened to her new friend and then her Uncle Pete. One minute she had been sat talking to her mum when a big scary bat looking creature appeared and then ate the Doctor. She was upset that her new friend was gone and she didn't get to say goodbye. Then her Uncle Pete was running from the church and had got hit by a car. She didn't know why he had said goodbye and to be good until that moment.

"Hermione?" she heard a voice called. She looked up and gasped at seeing her new friend safe. She ran to the Doctor and hugged him as he hugged her back. "Everything will get better."

"But Uncle Pete's gone." Hermione managed out.

"I know, but you have to be strong, for your mum and Aunt Jackie and especially Rose."

Hermione nodded "I'll tell her all about Uncle Pete."

"That's a good girl. Now why don't you find your mum, yeah." The Doctor said releasing her.

"Will I see you again?" she asked.

"Maybe." He smiled before he left to get Rose back to the TARDIS. He felt sad that the girl will now forget him, but maybe he'll see the grown up version of her when Rose ends up visiting her mother.

Hermione watched the Doctor leave before she left to find her mum. She promised herself that she will make sure Rose grew up to know how amazing Uncle Pete was and she also promised to keep an eye out for the Doctor and his blue box.
