TITLE: Hogwarts school of Witchcraft and Wizardry......and Aliens
AUTHOR: WhovianHarkness
SUMMARY: 'Ianto's day was going rather well until he got turned into an eleven year old'
When Captain Jack Harkness, Ianto Jones, Owen Harper, Toshiko Sato and Gwen Cooper get turned into children and sent to Hogwarts, what can go wrong? Or rather, what can't.
DISCLAIMER: I own nothing. Torchwood belongs to BBC wales, Harry Potter belongs to J.K. Rowling, and most of my inspiration comes from the book 'The magic of Torchwood' on fanfiction.net'

Jack woke up early the next morning, which was surprising, as he didn't usually sleep, so didn't usually wake up. Then he noticed Ianto lying with his head on his chest, fast asleep. He kissed Ianto on the forehead, and waited for him to wake up. When he did, he let out a yelp.
"Jack! We're eleven!"
"Calm down, Yan, nothing happened"
"Y...you sure?"
"Positive. Did you sleep well?"
Ianto nodded. The bell rang before either of them could say anything else, and Ianto slipped out through the bathroom, and took his clothes - Black jeans, and a more risky choice of a dark green shirt, which he nonetheless looked amazing in. Jack got into his usual light blue shirt, jeans, and suspenders, that if he wasn't in the wizarding world, where everyone wore robes, he was sure he would be mocked for. Probably still would if so many people didn't have a crush on him.
They agreed to meet the others in the great hall, and headed out, only to be stopped by a pacing Harry Potter.
"Hi. Jack Harkness"
"Oh, uh, hi"
"Stop it Jack, sorry about him, I'm Ianto Jones"
"Harry Potter"
"We know"
"Uh....I just wanted to apologise for Ron"
Ianto flushed slightly.
"Nothing that isn't true" he said, evenly.
"Oh......uh....erm......are you Welsh?" He quickly changed the subject.
"Yeah"
Harry nodded. "So... I heard you're starting a study group thing?"
"Nah, just friends studying with friends. If there's going to be a war, we better be ready"
Harry looked worried. "You think there is?"
"Better to be prepared for anything" Jack said calmly.
"Oh....uh....okay. Would I be allowed to join?"
"I suppose"
He grinned.
"Okay, so, library tomorrow at half seven?"
Jack looked affronted.
"I don't care if you're the chosen one or not, you aren't in charge. We meet at half six"
"Uh....okay. Can I bring Ron?"
"No!" They said at the same time.
"Sorry. Stupid question. Uh......see you there!"
He almost ran off, and they started to laugh, before following him to the great hall.
They sat with their house, as they had to at breakfast, and talked to Marcus Flint about their 'study group'.
"Well, if you ever need any help with anything.....how about you come down to the Quiditch pitch on Saturday, I'll teach you all to fly. Not enough to play Quiditch or anything,  but enough for safety. I refuse to coach Harry Potter or anyone on opposing quiditch teams, though"
They nodded and thanked him, before moving on to class.

That evening, at 6:00 in the Library, Jack informed them of the fact that Harry was coming, and they sat down to work, until Hermione called them over.
"Guys,  I found this book on animagi. It says it takes a minimum of three years to learn, so I thought we could start now? It would be an easy getaway"
Jack nodded.
"Okay, guys. Research animagi, but your part. Law, Politics, uses, the actual spell, potions. Do whatever part of it, but make notes, and give them to me and Yan at the end"
It was then that Harry came in, and sat down. Jack walked up to him, and handed him a book.
"Hello"
"Hi"
"If you research connections between humans and their animagus forms"
"Shouldn't I be learning how to defend myself if there's going to be a war?" He complained.
Ianto walked over.
"Imagine this. You're trapped in a cellar. Anti apparition wards, guards outside the door. What do you do?"
"Wait to be rescued"
"No, you shift into your animagus form, and escape"
He turned back to his book on Animagi in history.
"Hey, Jack, it says here that some talented wizards can cast magic while in their animagus forms."
"That would be useful. Thanks Yan"
Pansy and Owen were discussing the possibilities of using potions to reveal their forms, and after a quick flick through a book, they decided to start brewing as soon as they had somewhere to relocate to.

Harry walked back to his dorm. He was slightly annoyed that he had just been ordered around, and hadn't even been noticed by most of them, but nonetheless he had a thirst to prove himself. He took the book up to his dorm, determined to find something important.

"Jack?"
Pansy knocked on the door to the boy's dorm. He opened it. She was standing next to Daphne.
"Uh....Jack?"
"Yeah?"
"It's illegal to become an animagus under the age of 15"
"It could save our lives. No-one has to know"
Daphne nodded. "Just wanted to make sure"
That night, Jack crept out, and walked around the school looking for a suitable place to meet. As he walked down one stretch of corridor for the third time that night, he opened the door to reveal a room with a large library, a long table, a small artificial greenhouse, and a brewing area for potions. There were also some practice dummies, and a shooting range.
"How?"
Writing appeared on some of the parchment on the table.
This is the room of requirement. simply walk past the invisible door thinking of what you need three times'
He grinned widely. He couldn't wait to show the others.
