Yet again I don't own HP characters, quotes or plots. The only thing I own is my character. From this chapter on there will be POV from other characters not just me. This is what I'll use: name or Name. If I don't use that it's in my/Sean's POV

Chapter Three: First Day

Sean woke up to his first day of Hogwarts with both happiness and nervousness because it was

also his first day of teaching.

"Sean you up?" Harry whispered.

Sean opened his eyes to see Harry standing in the door frame.

"Yeah, yeah, I'm up. When did you get up?" Sean asked.

"An hour ago." Harry replied.

"Oh, why haven't you gone down to the Great Hall?" Sean asked.

"Uhh, because it's seven o' clock in the morning."

"What it's that early?!" Sean said stunned.

"Yeah it is. I couldn't sleep. What about you?" Harry asked wondering.

"Yeah I couldn't sleep either. I'm too excited and nervous at the same time. I can't believe I'm

here. It just seems like a dream." Sean explained.

"Hmmph, yeah I felt the same way my first year. I always thought I'd wake up in my room back

at the Dursley's dreading each day."

"Yeah, my life was pretty good back in the Muggle world but I'm still really glad to be here."

Sean said explaining to Harry.

"Well do you want to go down to the Great Hall for breakfast? There shouldn't be anyone

there." Harry asked Sean.

"Sure let's go. I didn't bother changing last night so we can go right now." Sean told Harry.

Sean climbed out of bed and followed Harry down the stairs and out the portrait of the 'Fat

Lady.' "Bye dear." The portrait called back.

"Did she just call you dear?" Harry asked Sean.

"Yeah she's really nice when she can be. Her and I have become friends since the first day of

school." Sean explained to Harry.

"Oh, okay." Harry replied.

They made their way down to the Great Hall and went to sit at the Gryffindor table.

"Sean it looks like they haven't found a Defence Against the Dark Arts teacher yet." Harry said

to Sean.

"Huh, isn't that strange." Sean said looking the other way smiling.

"It looks like we'll find out in class who it is." Harry said thinking.

"I really like the food they have here. They have every food I like." He said scooping some

scrambled eggs on his plate along with the French toast, pancakes and a lot of other stuff he had

on his plate. "I've never had all my favourite foods at once." He spoke with a mouthful of food.

"So you really like food." Harry said trying to muffle a laugh.

"Yeah." Sean said wiping his mouth neatly.

Half an hour later Hermione and Ron joined them.

"Looks like they haven't got us a Defence Against the Dark Arts teacher yet." Ron mentioned.

"Yeah, I think Dumbledore will surprise us." Harry told Ron and Hermione.

After breakfast Dumbledore stood up and opened his mouth, "May I have your attention."

When he saw that everyone was watching him. "As you may have already noticed there is no

teacher up here for Defence Against the Dark Arts. You will find out who your teacher is when

you arrive at your class. Now that you have heard this you may leave after the post comes in."

Dumbledore looked up and saw the owls swooping in.

Sean saw two owls flying his way, one was his owl, Moonbeam, and the other was one of

Hogwarts' owls. The Hogwarts' one dropped of his schedules and Moonbeam dropped off his

Daily Prophet paper.

"Sean could I see what you've got for the week?" Hermione asked.

"Actually I'd rather keep it a secret." Sean replied. "I got to go get ready for class."

Sean walked off out of the Great Hall and was met by Dumbledore outside the Great Hall.

"Hello Albus." Sean said to Dumbledore.

"Hello Sean, so I presume you're heading to your first Defence Against the Dark Arts class."

Albus asked.

"Yeah I am. I'm not sure if I can do it but I'll try." Sean replied to Albus.

"I have faith in you Sean; I know you will be able to handle this task. I also still expect that you

will try out for the Quidditch Team. I will be coming to tryouts today so I will see you then."

Dumbledore concluded.

"Okay, bye then Albus." Sean said walking off to the third floor. He walked into the classroom

and saw how boring it looked. He took out his wand, waved it quickly and immediately the

room turned into an almost immediate replica of the Forbidden Forest.

"Hello Sean, been busy I see." A voice said from behind him.

Sean turned around and saw Remus Lupin standing there. "Remus, nice to see you." He said.

"Yeah I thought it might be interesting to the students."

"So are you ready for your first class?" Remus asked.

"Yes, I was thinking though of you being in the class at first so everyone thinks you're back but

then I'll walk out and introduce myself." Sean explained.

"Good plan, well you go wait then in your office. I'll wait here." Remus said as Sean nodded and

went into the office concealed by a large tree.

Harry Back at the Great Hall

"Ron I think we should head to class. We have Defence Against the Dark Arts." Harry said.

"Yeah let's go." Ron said back to Harry.

The two headed off to Defence Against the Dark Arts and arrived one minute before it started.

They opened the door and gasped. They saw that the whole room was covered in trees, vines

and bushes. It looked like an exact replica of the Forbidden Forest.

"Harry look! Lupin's back!" Ron whispered to Harry.

"Yeah that's awesome Ron. Have you seen Sean? He just has disappeared." Harry asked.

"Aww, worried about your boyfriend Potter?" A voice sneered.

Harry turned around and saw Malfoy behind him. "Shut it Malfoy." He replied back.

"That will be quite enough you two." Lupin said.

"Sorry Professor." Harry said back to Lupin.

"Now may I have your attention. I would like to introduce you to your new Defence Against the

Dark Arts teacher—"

"Professor Lupin I thought you were our new teacher. Aren't you?" Parvati Patil asked.

"No I am just an assistant to help your new teacher. Now as I was saying, may I introduce you

to your new teacher, Professor Moonstone." Lupin said.

"What!" Ron, Hermione and Harry called out in shock as they saw Sean walk out of the office

door.

Sean

Sean walked out of his new office and out from behind the tree. "Hello class." He said to them

all.

"This is some kind of joke right?" Malfoy whispered to one of his friends.

"This is no joke Mr.Malfoy. Now as you now know I am your new Defence Against the Dark

Arts teacher." Sean explained. "Now let us begin. Today we will be practicing Patronuses. Now

I know that some of you here have already practiced Patronuses," He said winking at Harry,

Ron and Hermione who looked shocked. "But I thought we should try it out for those who

haven't…10 points from Slytherin Mr. Malfoy for talking behind my back." He said adding to

Malfoy who stood up straight in shock.

"You can't do that, I mean your just joking me. You're only sixteen." Malfoy sneered.

"Yes I can do that Mr. Malfoy, and because of your tongue Mr. Malfoy another five points from

Slytherin." He told Malfoy.

"Now as you know the incantation for a Patronus is 'Expecto Patronum.' I have brought a

Boggart to practice on. Now I know that most of you are not as afraid of Dementors as some

are, no offence to these people, but I asked Professor Lupin to trick this Boggart into thinking

you are. Now on the count of three I want you to think of your happiest thought and use it to

conjure a Patronus.

Now on the count of three. 1…2…3!" He said as he opened the door.

A Boggart came out and transformed into a Dementor. "EXPECTO PATRONUM!!!!" Came

from the entire class. A whole bunch of different animals came out from different students'

wands while others just spat out a silvery mist.

"Good job class," Sean said as he was forcing the Boggart/ Dementor back into the door. "Now

I want you to practice this by yourselves around the class till the end of class."

He let the other students go off and practice. A few minutes later Ron, Harry and Hermione

came to speak to him.

"Sean how did you become the new teacher?" Hermione asked.

"Well you know that thing the Sorting Hat said as he sorted me? Well it was that I'd make a

good teacher. I'm still in Gryffindor, actually I'm the new Head of Gryffindor and I was the one

who created the new password." Sean explained.

"That is bloody brilliant. But what is 'Hubba Bubba?' Ron asked.

"It's a muggle brand of gum that I really loved." Sean told them.

--BRRRRIIIINNNNGGG—

"Looks like that's the bell." Ron said.

"Lisn' guys I want you three to make sure no one tells the other students that I'm the new

Defence Against the Dark Arts teacher. Okay?" He asked.

"Okay." The three said.

The three walked to their next class while Sean got ready for his next class.

Harry

"That's really cool that Sean's not only the new Dark Arts Defence teacher but the head of

Gryffindor. You think we'll get lesser punishments now?" Ron asked the other two.

"Maybe." Harry replied.

"I doubt it. I mean now he's got a lot of responsibility. I don't think he can give anyone free time.

You saw what he did with Malfoy." Hermione explained.

"Oh guys I forgot to tell you. I'm the new Quidditch captain." Harry mentioned.

"Oh Harry, congratulations!" Hermione exclaimed.

"Ron the tryouts are tonight so can you make it?" Harry asked.

"Yeah. No problem. I'll be there." Ron replied.

…….Seven and a half hours later…..

"Hey Ron! Over here!" Harry yelled.

Harry watched as Ron ran to the Quidditch pitch with his Cleansweep Eleven in hand.

"Looks like there are a lot of people who want to try out." Ron said looking at the people

coming down from the castle.

"Hey Harry." Sean said coming up.

"You're trying out Sean? I thought you didn't know how since you just became part of the

wizarding world three days ago. So why are you trying out?" Harry asked.

"Dumbledore wanted me to. He told me he had faith in me. Even though I doubt I'll be any

good." Sean explained.

"Oh okay." He said. Then he turned to everyone else. "Sonorus." He pointed his wand at his

throat casting the spell. "WELCOME EVERYONE. NOW AS YOU KNOW WE'RE OUT

TWO CHASERS AND TWO BEATERS. We still have Katie Bell here, myself and Ron. Now

what we'll do first is the chasers. Katie and Ron will help out with this. Two of you will pass the

ball to each other and to Katie as well and try to score on Ron. Once everyone has done that

we'll announce who the two new chasers are. Then once we've done that we'll practice with the

new chasers and give the beaters tryouts. We'll see who are the best by you pelting the balls at

the chasers as much as you can. Then will announce the new beaters. First pair up."

Harry watched as the others paired up.

"OK on my mark." Harry blew the whistle.

Sean

Sean kicked off from the ground without anyone noticing he had a Firebolt. He began circling

around the field then swooped in and took the Quaffle. He passed to Seamus then Seamus

passed to Katie, then Katie back to Sean. Sean zoomed in and scored on Ron.

"Yeah!" Sean yelled.

The tryouts continued for the next hour until Harry blew the whistle.

Sean was already on the ground and listened for the outcome of the tryouts.

"Our new chasers are: Sean Moonstone and Dean Thomas and our new beaters are: Ginny

Weasley and Lavender Brown. Thank-you all for coming and to the new members our first

practice will be on Thursday after dinner." Harry told them. "Now you all may head back to the

castle.

After they left Harry went up to Sean. "Good job Sean." He said pausing as he saw Sean's

Firebolt. "Sean where'd you get the Firebolt?"

"I bought it." Sean replied.

"Huh, that's cool. You must have a lot of money in Gringotts. Do you?" Harry asked.

"Yeah, I have a lot of money. Just like Sirius." Sean said, then kicked himself mentally realizing

he had let it slip that he knew about Sirius.

"Sean did you just say 'Sirius?'" Harry asked.

"Umm... yeah?" He asked nervously.

"How do you know about him?"

"Uh, I can't explain exactly, but I know he is innocent." Sean explained.

"You believe he's innocent too?" Harry asked.

"Well yeah and I sort of know that he is your godfather." Sean replied.

Harry and Ron gasped. "Uhh n-no he isn't." Harry stuttered.

"Lisn' Harry, in the muggle world a woman named J.K. Rowling who lives in England wrote a

set of books of your years at Hogwarts. She's at the fifth year. I don't know how she knew

everything that happened to you but anyways I know everything so if you need to talk to

someone about this stuff and Dumbledore, Ron, Hermione or McGonagall aren't around just

come and talk to me. K?" Sean asked.

"Okay fine. Lisn,' Ron and I got to get to the Gryffindor Tower.

"Okay, I've got to go patrol the corridors with the prefects and other heads. I'll see you later." –

POP- With that Sean disappeared into the corridor next to the Head Boy. "So what's new?" He

asked.

"Oh hi Professor Moonstone." The boy said just noticing him.

So what'd you think? This is NOW my actual longest chapter so far that I've ever written. Please R/R. And please tell me what I should the next chapter be about?
