Series – Hogwarts and Halliwells

Title – Become On With The Animal Inside You

Summary: 4th in my Hogwarts and Halliwells series. Harry, Ron and Hermione's animagus potion is almost complete but the Charmed Ones find out and want in. Who will be the ones to take it? And what about a Halloween costume ball? Harry Potter Charmed Xover. Major AU.

Disclaimer: I did not own Harry Potter or Charmed yesterday, I do not own them today and I will not own them tomorrow. But I can always hope about the day after that, can't I?

Other Information: This is a Harry/Ginny and Ron/Hermione fic. Remus is a wolf Animagus. Lily's is about 4/ 4 and a half months pregnant and will find out the sex in this story. Read my other stories first chapters for vital information.

This is the fourth in my Hogwarts and Halliwells series, so here is a little recap of the previous instalments:

My Parents, the Whitelighters: Harry has a dream of the Charmed Ones and asks them for help in summoning his parents. It fails but Leo comes down from 'Elderland' with Lily and James, who are now Whitelighters (James is Remus and Sirius' and Lily is Harry, Hermione and Ron's.). They return to Grimmauld Place to tell Sirius and Remus. After the reunion, James goes to the ministry to tell them that he is alive and that Sirius is innocent. It is announced in the Daily Prophet and Lily, James, Harry, Sirius and Remus move to Godric's Hollow (the real one, not the one that was blown up, which was a safe house with the same name).

Harry Potter and the Last Battle: An Elder tells Lily and James that everyone has to help Harry defeat Voldemort. The Elders discover there are Kinetic Charmed Ones and release their powers. Harry, Hermione, Ron and Ginny turn out to be those Kinetic Charmed Ones. They have to learn to control the powers and train to defeat Voldemort. Ron and Hermione & Harry and Ginny start dating. When they arrive at the battlefield, James, Sirius and Remus run into Wormtail while Harry and the others go straight to Voldemort. The Marauders find them and Voldemort casts Avada Kedavra at Harry. Wormtail jumps in the way, fulfilling his Wizard's Debt to Harry. Harry then casts Avada Kedavra with Hermione, Ron and Ginny and Voldemort is finally killed. In the end, Lily discovers that she is pregnant.

The Charmed Professors: Dumbledore goes to the Charmed Ones to ask them to become the new DADA teachers. They accept this offer after finding out they all have wand magic. Leo is also a wizard but came from a Muggleborn family so didn't know. For their first lesson with the 7th years, they summon Grams to show them Wiccan magic. When they talk to Grams after the lesson, she tells them that Harry, Ron and Hermione are to receive more powers soon. Sure enough, Harry receives telekinesis and astral projection, Ron receives premonitions and levitation and Hermione gets freezing time and molecular combustion. Draco asks Paige out on a date and she rejects him, because he is so young.

Now, ON WITH THE STORY!!!

Welcome to the fourth story in the Hogwarts and Halliwells series! I really hope you enjoy this chapter! And I'm very sorry that I lied about when it was coming out, my internet didn't want to work for a few days, lol.

Chapter 1: Preparations

Hogwarts...

It had been nearly two years since the potion had been started, but now it was nearly ready. Hermione stirred the potion and added a pinch of billing's root. She had seen the potion go through everything, and it was lucky that it didn't always need to be on the heat. Two summers it had been taken to her house with her, with just simple ingredients needing to be added. Finally, they were within the week margin of finishing. Three more ingredients needed to be added. One would be hard to get, but they would get it somehow. Harry and Ron burst into the bathroom.

"Finally boys. Where have you been?" She asked.

"Sorry Mione, Snape wanted a word with us. Something about apparently disrupting Slytherins while they were studying. I have no idea what he was talking about though." Harry said, with that glint in his eye. The one James, Sirius and Remus got when they were doing something like a prank.

"Harry James Potter, don't tell me that you pranked the Slytherins." Hermione said in a stern voice.

Harry looked at her. "Ok, I won't." He said with a grin.

"Harry!" She screeched. "Why did you do that? You know that-"She was cut off by Ron kissing her. When they parted, she looked dazed. "What was I saying again?"

"Nothing much, just about the potion. How is it coming along anyway?" Ron said.

"Pretty well. Just the Griffin's claw, Hippogriff crown feathers and Dragon saliva. We have the first two, but we need to get the saliva from Snape's private stores."

"Mione, have you lost a screw somewhere? How are we supposed to steal from Snape? When we made the Polyjuice you stole the ingredient." Ron said.

"Do I have to do everything?" Hermione snapped, creating a small flame that appeared in front of Ron.

"Hey, no using your power on me! I only have one active one." Ron complained.

"If I could freeze you…" Hermione pointed in his face, making the flame disappear. "I've done everything we can for now. I'm going to go and see Piper. I want to see how I can stop myself blowing you up." She stormed out of the bathroom. In front of Harry and Ron, Myrtle suddenly appeared, making them both jump.

"She's been very upset lately. In here, crying to herself."

"What? Crying? Do you know what about?" Ron asked.

"No, but she did mention the name Ron." Myrtle giggled. Ron turned white.

"I think I need to talk to her." He ran out of the bathroom.

"Well Harry, now we are alone, we can talk." She said.

Harry gave her a funny look. "Myrtle did you just make that up so you could talk to me alone?"

Maybe…" Myrtle giggled again.

"Myrtle, one you're a ghost and I'm not. Second, I have a girlfriend." Myrtle pouted.

"Well you don't have to have her. You can have me. Forever. Just one little jump out of a window…"

"Myrtle, I am not jumping out of a window. I love Ginny and if you don't leave me alone, I will make sure that the Bloody Baron will make you wish you had never become a ghost. Now leave me alone!" Harry stormed out of the bathroom, to tell Ron that Myrtle had been lying.

Head Dormitories…

"I can't believe that ghost, I hate her so much now." Ron said. Harry had arrived just before a fight between Hermione and Ron had broken out.

Hermione snorted. "Why would I go in there to cry anyway. I do have a private room. And I haven't been crying anyway." She looked thoughtful for a moment. "Do you think that the Charmed Ones Book of Shadows has anything that will help a ghost move on?"

"I think so. I think I remember a story they told us about a ghost they helped move on." Harry said. "Maybe we should go ask them?"

"Maybe." Ron said. "Was it like this with Myrtle in our 2nd year?"

"Moaning Myrtle problems. Trying to get me to commit suicide so I can be with her, Merlin." Harry shuddered. "Like I'd do that anyway."

"But what do we do now? We have to go in there for the potion." Ron said, flopping on the sofa.

Hermione seemed deep in thought about this. "Harry, Ron, you know the Charmed Ones tower? Aren't the north, south, east and west towers laid out all the same?"

"Yeah. Where are you going with this Mione?" Harry asked.

"Well, what if there was a glamour charm on this tower. To make some of the rooms disappear?"

"Then we would have 3 more rooms, and the middle tower room. And we could move the potion to here. Brilliant." Ron said. "How did you get so smart?"

"She always has been." Harry smirked, only to have a pillow thrown at his face. "Oi, Mione you know I meant it in a good way."

I know. I just felt like throwing a pillow at you." She smiled. The portrait opened and a weary looking Ginny Weasley entered.

"Hey guys. I had to talk to Hagrid for a minute and he kind of turned it into 15 minutes. What's up with you lot?"

"Nothing. Hermione had a run in with Moaning Myrtle. And then she tried to get Harry to kill himself so they could be together." Ron said, stroking Hermione's hair.

"WHAT?!?" Ginny screeched. "That ghost tried to get my boyfriend to… Ooh, I am so going to banish her straight to hell!" She went to storm out of the portrait again, but an unknown force was pulling her back. Straight into Harry's arms. "Harry! Let me go do it!"

"No Gin. We're going to look at the Charmed Ones' Book of Shadows to see if there is a way to let her move on. We don't want anything really bad to happen to her."

Ginny thought it over and nodded. "Ok then. I won't kill her again. When are we going to ask them if we can see it?"

"We'll do it tomorrow. Now, who wants to go down to Hogsmeade for an hour or two?" Hermione said. Everyone in agreement, they changed and set off for Hogsmeade, Hermione telling Ron in his mind to pick the Animagus potion up on the way back and put it in her room. She would make an excuse for him while he was gone.

Well, what do you think as a first chapter? I'm going to try to make this story longer than TCP but no promises. If it isn't longer, I'm going to be upset. And I'm going on holiday Monday so I'm getting as many chapters out as I can before.
