Chapter 4

Professor Kettleburn showed them something similar to a frog with fur and rabbit ears that day, which he said was a Steapzon. He said that they would be taking care of them until they grew to about the size of a Chihuahua, which would be the peak of their maturity and the magical potency of their fur for certain healing potions.

"I think I prefer Flobberworms to those little monsters," Ron said rubbing his index finger where a red mark was now, "Those teeth are sharp."

"You'll just have to put on some gloves next time. Are you sure you don't want to go to the hospital wing?"

"Nah, Kettleburn said they weren't poisonous so it should be all right. We need to go see Professor Manning now though."

"Why are we going to see Manning though?" Hermione piped in.

"We'll discuss it when we get there," Harry replied.

"Hey guys, where are you going? Lunch is this way!" They looked around to see the Marauders waving for them to catch up.

"We can't, we have to go see one of the professors," Harry answered back.

"Already in trouble are you?" Sirius said mischievously, "Well, don't let us stop you from making more trouble. We can't be the only ones who do it after all." Before Harry could protest they were gone.

"Come on Harry, we need to go." Harry then followed Ron and Hermione to see Manning.

When they got there, Manning didn't look one bit surprised that they showed up.

"You've had the vision, Harry?" Harry nodded his head, not very surprised himself considering Manning had seen it himself though a very long time ago to him.

"So you know what I saw?"

"I have my suspicions but it would be best if you told me anyways." Harry told them all the part that he kept out and Manning nodded his head gravely.

"Yes, that would explain some things."

"Explain what," Hermione asked.

"I remember that my first class in my sixth year, which would just so happen to be the next class I am going to teach, was something I wasn't expecting. I gave a lesson on patronus casting."

"So that your younger self and the rest of the Marauders could fight the Dementors?" Manning nodded.

"Shouldn't we go and help them?"

"Oh, we will. At least one of us will." Manning's eyes drifted to Harry.

"Why just me?" Harry's godfather shook his head.

"I really don't know. You were the only one that showed up though."

"I think there's one thing that we haven't covered though," Hermione put in, "What were Dementors doing on the school grounds?"

"That's something I don't know. Perhaps you'll find out later on. Here, you three must be hungry and you won't have time to get back to the great hall for lunch." Manning conjured up a platter of sandwiches and goblets of pumpkin juice. The three saw this as the end of the conversation and said no more.

As soon as they were done with the last sandwich, students began filing into the classroom. With a wave of his wand, Manning had the platter and goblets disappear and escorted the three out of his office. Student that thought they would be first looked disappointed as they saw the three step out from the office. They got into their seats though, ignoring the looks the other early birds gave them.

Not too far after the rest came the Marauders and Lily. They waved at Harry and his friends and took some seats around them. Peter and Lupin sat together, Lily sat by Hermione, Sirius by Ron, and James by Harry after Sirius insisted in hopes that it would confuse the new teacher. Everyone grew quiet then and looked up at the teacher, who had just stood up from his desk.

"Good afternoon class. For those of you who that have not met me yet, I am Professor Manning. Today, I'm going to cover something that not many of your teachers cover. Does anyone know what a Dementor is?" A raven-haired Gryffindor girl raised her hand before Manning had finished his question, much to Hermione's annoyance.  He called on her. "Yes, Miss Heethley?"

"They are the creatures who guard at Azkaban. They have hoods and are all black."

"Yes, good. Five points to Gryffindor. Can anyone tell me the effects a Dementor can have?" Hermione's hand shot up and he called on her.

"They take all the happiness out of you and if they get too close to you, they may kiss you."

"A kiss?! What would a creature like that be doing that for?" Came the snide comment of a Slytherin.

"It's what they call it when a Dementor sucks the soul of a person out by their mouth. The Dementor's kiss," Manning said, "Good job Miss Green. Another five points for Gryffindor." He then walked to the front of his desk.

"There is only one thing that can fight off a Dementor and that is the Patronus charm. For the next week we will work this spell. Now, we need a demonstration. Harry, would you please come up here?" Everyone stared at Harry as he slowly got up, looking at Manning as if he were crazy. When he got up to the front he whispered softly to Manning.

"Snuffles, what are you doing? I can't show them my Patronus."

"You're the only one that can do it in this class well enough."

"What about you?"

"Mine's not as good as yours and besides, it would be the same as my younger self. Don't worry Harry." Harry reluctantly nodded his head and then went to the side of the classroom.

"Harry here will demonstrate to you what your Patronus should look like once you have mastered the spell. It won't be the same form as yours but it will be as solid as it needs to be to work very well. Harry?" Harry raised his wand and did the wand movement.

"Expecto patronum!" The silver light shot out and formed into a stag. Everyone stared at it in awe as it galloped around the room a few times before it dissipated. Harry looked over to the Marauders to see if they had reacted to his Patronus' form. They all looked a bit thoughtful, though Peter looked more in awe than anything else.

"Thank you Harry! Five points to Gryffindor for assistance. You may take your seat now." Harry took his seat, carefully watching James out of the corner of his eye for anymore reaction.

"As you just saw, the incantation is Expecto Patronum. Tomorrow we will all practice ours, but for now I will cover a few things with you. The Patronus takes the form of what you feel would protect you, and you must hold a happy thought in your mind for it to successfully to work." (A/N: I hope that's correct! I can't remember!) Manning went on with the right wand movements and other procedures until the bell rang and class was dismissed. It was no homework for them except be prepared to practice until next class. Harry left the room, still wary of the Marauders' if they might ask him why his Patronus was a stag that looked like James' animagus form. They didn't ask any question though, much to his relief.

His Patronus had been him! James couldn't believe it. Not only did this boy look like him, but his Patronus looked just like his animagus form. He didn't want to ask though. Harry seemed to have no ill intent so it didn't seem a threat. When the teacher had covered the information about why the Patronus takes a certain form, this made James curious to why Harry would find this form to be a protector. How did Harry even know how to do the spell? By what Professor Manning had said, it could be difficult and takes awhile to accomplish. But of course, James still didn't know Harry so he didn't want to judge so soon. He'd have to keep an eye on him though…

A/N: Like? Review then to tell me if you do or don't. Constructive criticism is very welcome. Sorry that it's shorter than the previous one. I came sooner than that one though, didn't it? I hope I don't have too many mistakes in here.
