Chapter Eight:

Hogwarts September 1st2017:

Delphi was going to really give Albus a heart attack when she was introduced. She was going to help teach defense this year as there had been rumors of something dark coming and she needed to be there to see that her family was safe. She would teach the muggle defense which she was good at. Though she was not as good as Fleur who was able to knock her down in every training they ever had. There was a reason she was a Triwizard champion and why she was feared to this day. Delphi had chose robes in emerald green and had changed her hair back to black, she felt purple hair was not the way to go as a professor. She grinned as Albus got sorted to Slytherin and walked to his new table with his new friend Scorpios. Finally she decided to make her entrance as McGonagall introduced her.

"And I would be pleased to introduce our new muggle defense professor, professor Delphi Potter Black." McGonagall said watching as Delphi glided up to the front of the room, "welcome professor Black."

"Thank you headmistress, I will make this short. I am going to have so much fun!" Delphi said smiling wickedly.

"Yes well, dinner is served!" McGonagall said primly.

It was and it was as grand a Hogwarts feast as any Delphi remembered. She sat by Flitwick and chattered on with him in French. It was very common for most magicals to speak at least two other languages so this was normal. Hagrid spoke French better than his native English, but then he was proud of his working class roots from his father's side and so he had always refused proper English. His hair and beard were still dark but he had taken to tying back his hair and braiding his beard. He was clad much the same as he always had but he now had a staff that he used instead of a wand. She watched as James walked over to the Slytherin table and spoke to Albus who lit up at James words and then he nodded fast as James no doubt reminded him of who was teaching here this year.

The very first day of teaching was with the first years. This was not a hard class as the first years were willing and eager to learn. Most had not had any martial arts training and so the basics had to be taught. However there were a few that had, like Albus and to her surprise Scorpius. They would help her out and she was glad to have that help both boys it turned out were patient and good teachers in their own right. Albus seemed calmer than in the summer and she knew it had to do with the letter her uncle Ron wrote him. Whatever Ron had said to him had made Albus happy and he had written back, Delphi was not going to pry into what he had said but she knew he did not hate Slytherins anymore. That first lesson cemented her place in Hogwarts and made her a beloved professor in Hogwarts.

The years passed all too fast after this, the blend of students, teaching and other things and five years were gone by and Albus was growing into a fine young man. Yet Delphi knew he was hurting as he had said some unkind things to their dad and had stormed out to come back to Hogwarts right after Christmas. She knew he felt awkward at times, Merlin she felt the same way. This was why she was headed to the chapel of Hogwarts, a Gothic space made for worship and holding an organ saved from the rampage of Henry VIII as he dismantled one abbey after another. It was not a large organ, only having two keyboards and the pedal organ, but it had plenty of stops. She walked in and heard Albus practicing, either him or Scorpius, they were like brothers and even James had taken Scorpius under his wing, Alice was busy getting ready to get married to a Martin Stone as soon as she graduated and so was not around much.

Delphi walked up and smiled as she saw James here with his best friend Frank Jr. This was Neville and Hannah's eldest child. They were watching Albus and when Albus started to play Bach's Toccata and Fugue in D minor. It was clear he had been listening to his lessons as he used the chapel as part of his instrument. Scorpius helped him with the stops and James just stood and watched his baby brother play. It was then Delphi saw Lily, who was a far better player of the organ than Albus but he needed this now, he needed to feel the music and not think on what he had said and done. The Potter family was musical, Harry played piano (he had learned from Mrs. Figg) Ginny and her family sang, James played lute and both Albus and Lily played organ. Delphi sang and played drums. When Albus was done Delphi smiled, she loved Bach and loved it when one played his music correctly.

"Walk with me Albus." Delphi said.

"You professor or sister now?" He asked.

"Sister, let's take a walk, I just need to talk to you, I talked to James, and Lily, your turn, eldest child privilege."

They walked heading out of the chapel, down the hall and up to the Astronomy tower, they did not go outside, it was far too cold but they found a room here and took a seat looking out over the vast grounds. It was private here and here Delphi could talk with Albus. She knew what he was feeling, of all the children he felt the darkness as much as she did. She knew this and felt for him, he was scared and even his best friend had a hard time getting to him. Scorpius was not even dark, he was so light his father commented on it. In fact he was studying to become a healer and Draco had mixed feelings but was accepting of it. Delphi started to talk, to talk about her fears, and how she was scared she would end up not like her parents but like those who gave birth to her. She told Albus every fear she had and that she felt she would never be good due to the taint within.

"But you are good!" Albus said, "you have never done those things they did and mum and dad love you."

"Yes I know, and they love you too." Delphi said.

"I hurt them and I don't know how to fix that!" Albus said.

"More like worried them, you know they understand the darkness, they lived it, look what dad was, and mum, the diary, yes they understand it. Talk with them, I know it is hard as a teen but talk to them. You will be surprised at how much they know you already and love and understand."

"I guess I should write a letter." Albus said.

"You could."

"Should we go back and stop Lily from playing Thunderstruck on the organ?" Albus said.

"No, its funny when she does that." Delphi replied, "now mum and dad are not the only ones you can talk to, I am here."

"Yea, but the other kids will talk."

"I am not the only family teaching here their own siblings or kids you know." Delphi said, "I have never favored you in class."

"No you are mean to me." Albus said.

"Pass for now, but once we leave this room I am professor Black again."

"Yes professor." Albus said.

"Oh and if you ever prank me again here at school I will be very put out." Delphi said getting Albus to pale, "I wont even tell mum and dad."

"Yes ma'am." Albus said.

Later Delphi got a wall mirror call from Harry who was happy she had spoke to Albus. Ginny was there too and they had some bad news. At the home of the Nott family they had found a time turner, one that could go back years and Harry wanted her to come home as they had something to tell her that he hoped she would not take badly. It was then Delphi knew, knew what Harry and Ginny had done all those years ago, knew they had gone back in time.

"It's time you read the letter, a letter written for you." Harry said, "we only could read the part for us, and we will do what it says, but you need to come home and claim the other part."

So yes, time travel was used and this is the future as it should be. What will the letter say? Yes when done properly Thunderstruck on pipe organ is amazing, you need someone who can do it right otherwise it is just a bunch of noise. No that person is not me, I can barely sing and I have never so much as touched an organ in my life.

Anyway, do review please.
