Serenity couldn't believe what she was reading. Dumbledore was offering her a position she isn't qualified for, Defense against the Dark Arts. During her Hogwarts years, she was a good student and got top marks in her classes, but DADA was one of her least favorite classes. She was really good, but she didn't the idea of dueling. Anyone who challenged her to a duel ended up in the hospital wing with a big 'get well' card.
'But why would he offer me a big position as this?' she thought. Well, she knew what her answer will be, NO. She took out a piece of parchment and a ballpoint pen and began writing.

Professor Dumbledore,
I'm truly sorry, but I can't accept the DADA position. I feel I'm not the perfect person to teach. Please accept this reconsideration and hire someone more suitable for this position.
Sincerely,
Serenity Beckinsale

Serenity called Olivia and tied the letter to her leg. As she watched Olivia fly off, she wondered if she made the right decision and wondered WHY would Dumbledore offer her a position like that.

The Next Day....
Dumbledore walk into his office at Hogwarts and saw a snowy owl with piercing red eyes net to Fawkes, his phoenix. The owl has a letter attached to its leg. He untied the letter, gave it a owl treat, and a pat on the head, as it was about to take flight. Dumbledore read the letter and had a smile on his face after finishing it. On cue, Minerva McGonagall entered the office. "So, Albus," said McGonagall, "did she accept?"

"I'm afraid not, Minerva," Dumbledore said, "I think I should go to St. Mungo's and talk to her myself."

"No offense Albus, but Serenity doesn't like that much. In fact, you're on her ten most hateful people list, ahead of Lord Voldemort."

"But Minerva, she must teach at least two years at Hogwarts, for her's and Harry's sake."

"You know that she might hex you. She knows bountiful of hexes and curses that will kill you, and they aren't the unforgivables"

"I have to take may chances, right? Beside, she has to accept that I'm her great-grandfather one day."

St. Mungo's Hospital.------------------------------

Her fellow co-healers for her cure were congratulating serenity for the Cruciatus Curse when she saw the person walking towards her she least expected. "Hello Professor Dumbledore" she said coolly. When those word exited her mouth, every head turned to Professor in worry he is sick or wounded. "Hello Serenity. Might I have a word in private?" he asked. Serenity didn't like him at all, but she didn't have a choice for it would be 'rude' to hex a well-known wizard in front of people. "Of course Professor, shall we go to my office?" she grinned. Serenity led the way to her office. With the click of her door closing from the inside, no one on the other side of the wall will hear screaming or yelling because her office is soundproof.

"WHAT THE BLOODY HELL REASON DID YOU COME HERE FOR?" she started. "Well, I needed to talk to you about something."

"Well, spill it out! I have patient that need healing."

"It's about the Defense Against the Dark Arts position. I just came here to explain to you why it is important that you take the position."

"No matter what you say, I will NEVER take that position. Give it to my worst enemy for all I care."

"Well, let me start explaining. Our Divination professor at Hogwarts foretold the future last week....."

"Is this the professor that isn't a seer and predicted the death of me at he age of 16?"

"Yes, as I was saying......."

"Who is also crazy?"

"Yes, just let me finish. Well, she foretold the future that involves Harry Potter and yourself. She foretold that Lord Voldemort will rise in two years. She said that in this two years Harry Potter must train for the last battle between himself and Lord Voldemort. He must be trained by the person who mastered Occlumency, is a fire and water elemental, who has the ability to heal, and is a relative blood to two of the founders of Hogwarts, you."

"Um, first of all, that isn't enough proof Trelawny is CRAZY. She's out of her mind."

"I have other proof. Professor McGonagall is a true seer and foretold this as well. This is why I need you to teach for two years. Please reconsider this position." Serenity was in deep thought. She wanted Lord Voldemort to die for what he did to her parents. But she didn't want work at Hogwarts.

"If I do this," Serenity said, "I only have to teach class, right?"

"Well, you also have to do private sessions with Mr. Potter. He did Occlumency with Serveus, but I think he was terrified of him."

"Fine, I'll take the position for only two years. But during Holiday, I'm coming back here." Professor Dumbledore was happy that she agreed to the position.

"Great. Give me the book list you want your students to buy for the term. Is there anything I could do to help?"

"Well, can you give me a copy of the itinerary of Remus Lupin and info on all the students?" she said. With a flick of his wand, loads of folders and papers were on her desk. "Thank you. I'll see you in August," she said. With a little bow, Professor Dumbledore disaparated. 'What did I get myself into?'
