Albus enters the Potions classroom at 7, 30. He thought he better make sure the place was in order and perfect before he started his first class, which was with 1st years Hufflepuff's and Ravenclaw's.

Unsurprisingly the potions class room was immaculate. He ran his finger over one of the potion desks and smiled when he saw that there was not a speck of dirt on his finger. In any one else's class, he would have put the clean room down to the work of the house elf's, but he new that Severus was never one that liked the idea of someone else doing his work.

He always said that if you didn't clean up your own mess, you will have a hard time cleaning anything else up. He also considered it very lazy and he didn't like having people touch his things.

Albus sighed thinking about his classes today. He wondered what there reaction would be when they saw that they didn't have there normal potions master. Relieved was what he would have guessed. It seemed that no-one liked there potions teacher because of how strict and unfair he is. He let out a little laugh at the memories of some of the students complaining to him about his behavior.

He had tried to sort it out by telling those students that they should not pay any attention to his moods and that he is only like that because he was made that way. He frowned at this. He knew that Severus didn't have a good childhood and that being in Slyitherin house made everything worse for him.

KNOCK KNOCK

Startling him out of his thoughts, he went and opened the door only to find___ "Good morning Minerva" he said with a smile on his face.

"Good Morning Albus, I see that you're getting back in the habit of teaching again" she smiled at him knowingly. Albus was Transfigurations teacher before she took over from him and he became headmaster, and every so often he liked to take over a class or two because wanted to.

"Yes I am, only for Severus though". He said with a smile. "What can I do for you Minerva?" he asked, wondering why she had come. She looked at him for a moment before giving him what Severus gave too her. He looked at it and established that it was a class schedule. He chuckled a little at Severus's stubbornness when it comes to his classes. "Thank you Minerva, could you tell Severus that I will follow his lesson plans word-for-word" he said with amusement. She laughed at him and said that she would deliver the message.

After she closed the door, he looked to see what he had to do with the students. 1st years Ravenclaw's and Hufflepuff's were to be taught how to do a swelling potion.

Next there were.

3rd year Gryffindor's that will be doing a pepperup potion.

2nd year Slyitherins that will be doing a sleeping potion.

And finally the 6th years Gryffindor's and Slyitherins that will be doing a de-aging potion.

Interesting he thought. Albus was really looking forward to teaching Harry. Since the end of the 5th year he had not been able to talk to him at all because he was avoiding him. Dumbledore suddenly felt a pang of hurt and guilt because of this. He knew Harry did not hate him, he just did not know if he could trust him again.

Dumbledore hoped that this year would be better for him and he made a promise to himself that he will, in some way before the end of the year make Harry feel needed and loved.

Nodding to himself at this final thought, Albus looked at his watch and decided that it was time to set things up for his first class, before he went down to the hall for breakfast.

Albus was in a good mood

________________________________________________________________________

Later on that day Albus was still in a good mood. He had gone through his first 3 classes without any hassle. He had never been any good at potions which is why he asked to take over the lessons, but he had actually enjoyed it. Each one of his classes had seemed so relieved that they were not being taught by Severus.

His next and final class was the 6th year Gryffindor's and Slyitherins. He had heard so many stories of what goes on in that class from Severus that he was just determined to find out what it was actually like.

Ten minutes later his last class came in. they didn't see him there, standing by the desk invisible and watching how everyone came in. While the Slyitherins were making more noise than the Gryffindor's, both of the houses were very quiet. There was no fighting between the houses like Severus had told him, but there was a lot of apprehension from most of the student. Severus had told him that most of his students were afraid of him.

Once they were all seated, Albus walked to the back of the room and reappeared when no one was looking.

"Good evening class" he said over the small amount of chatter that was playing around the room. All the students looked at him for a moment stunned. "Before you all ask why I am here I am going to tell you. Professor Snape will not be teaching you this week because he is, at the moment unable to, so I am going to take over your classes" He looked around the class in a way that no one would notice.

He saw that most of the Slyitherins were not happy with this as they were moaning softly to one another. Probably about how they will not be able to pull one over me he thought. But the Gryffindor's had a completely different reaction. Most of them were whispering yes to each other, and the rest of them just sighed in relieve. Neville practically looked like he would jump for joy, Poor boy.

However not all of the Gryffindor's had a pleasant reaction. Harry was not looking at him and he had his head down. Dumbledore's heart sank a little. Harry was one of the boys in this class that he wanted to please with his presents there, but I guess he is still unhappy with me.

Deciding not to dwell on it further he started the class.

"Now, Professor Snape has kindly told me about how far you are with this year's potion making and he has told me that you now have to make a de- aging potion". He looked around to see a lot of nods from most students and a few scared looks from Neville and other students that potions is not there best subject.

Smiling he asked "Now who can tell me all the ingredients that are required to make this potion?"

Straight away Hermione's hand shot up.

It was quiet obvious that she wanted to show him how much she knew so he let her answer him. As she read out the names of all the ingredients he put them up on the board with his wand.

Once she had finished he smiled at her. "Excellent Miss Granger, 10 points to Gryffindor". "Now, since this potion takes most of the double lesson to do, I suggest you start, if you need any help (looking at Neville) you can always ask me for it, begin".

45 minutes later the class was still working on there potions and not one person had asked for help. Severus must have made them look small or something when they did ask, which must have scared them into doing t themselves.

This was a very big surprise since when he asked other Professors if they asked for help, they always said yes. He was hugely surprised by Neville as he has not asked yet. He must only ruin his potions when Severus is around, he thought.

Seeing as he had been sitting behind the desk for a long time, he decided that it was time to look over the students potions.

It looked like most of them were doing a fine job. He went over to the Slyitherins first. Giving out a few complements to the ones that were doing there's right. Mr. Malfoy had his potion brewing fine, a little bit of color, but it was close enough. Smiling he looked at his friends potions, (Crabbe and Goyle) both of there's were a horrible shade of green. The potion was meant to be a light blue.

He gave them a little hint that they should put in a little bit of Gillyweed to put in back to the right color. They quickly did so.

Albus then set of towards the Gryffindor side. Most of them were doing excellently. Harry was working beside Ron and both of there potions were perfect. Dumbledore complemented them both on there potions before looking around at the other Gryffindor's.

But before he had chance to look at anyone else's, there was a loud sizzling sound that was coming from the front of the class. He quickly found where the sound had come from by the looks of apprehension and dread that crossed most of the student faces.

Albus moved out to see what the potion was doing. The student that the potion belonged to was Neville Longbottom. The cauldron was shaking madly and was on the verge of exploding. Realizing quickly what was going to happen, Albus ran towards Neville and the students near the cauldron and moved them away. "Move it's going to explode" he cried. Unfortunately for Dumbledore, he didn't have enough time to move out of the way before the potion exploded all over him.

Everyone looked at there headmaster in shock and worry as they watched his facial features go from dread to complete horror. Suddenly there was a bright orange glow around the headmaster, and he slowly started to grow smaller.

Everyone looked at there teacher with horror in there face. Neville was practically trembling with shock as he watched his headmaster shrink.

Down down down, the headmaster went until some of the students thought he would get so small they would not see him again.

Finally the orange glow went and disappeared behind one of the work benches.

Slowly every one moved forward to look over the bench.

As they appeared over the top, they were all completely gob smacked. The sight that greeted them was of a small boy of about 2 years, with bright blue eyes and short auburn hair. He was wrapped up in the headmaster's robes and was looking very sad and scared as he looked up at the students.

Suddenly some said.

"Oh my God, we've just De-aged Professor Dumbledore".
