Chapter 27: Truths part 1

April had finally arrived and Dahlia thought that the DA was finally ready to learn the Patronus charm. They needed to if her assumptions were right that the Dementors were not under the Ministry control anymore. Everyone was very keen to work on their Patronuses but Dahlia warned them, "producing a Patronus in here will be easier than when you're faced with the Dementor. Then, you have the fear of them stood right in front of you and having trouble with thinking of just a happy memory. The incantation is 'Expectro Patronum' and it's a swish of the hand, like this". She did the incantation and everyone was expecting to see the stag appear but something much bigger and winged like appeared out of her wand. It was a Thestral.

Dahlia was surprised, just like everyone else in the room at the change of her Patronus. Since the recruitment, everyone believed that she had a stag for a Patronus; a Patronus meaning determination, vigilance, and intuition. Now it's a Thestral, a very rare Patronus at that; loyal, protective, fast, wary, a creature that is strongly misunderstood because of its differences. She looked around the room to see everyone staring at her as her Patronus disappeared, she coughed and said, "now, I want everyone to try that spell. Spread out".

They did just that but Hermione and Ron pulled Dahlia aside and Ron asked, "what's wrong with your Patronus?"

"Don't you know?" Hermione said, "a Patronus can change throughout a wizard's life, it doesn't always happen. It can transform due to a period of bereavement, a shift in the persons character, or love".

"Love?" Ron exclaimed looking between the girls.

Dahlia shrugged and said, "I don't wanna talk about it. Just...go practise".

So, they did, rather reluctantly, and Dahlia already knew why it happened, or she assumed why. A Patronus charm usually takes the form of the commonly found animal in the caster's country which represents them, which is why many of them were cats and dogs. Dahlia now considered somewhere else her home, she became a different person since meeting her sister, discovered the truths of her life and of course family love contributed. After all, she wasn't alone anymore.

Dahlia walked around the room, examining everyone's performances and helping them in any way she could. Whether that was through wrist movements or pronunciation. She kept on reminding them that it would be different when it came to a Dementor but it was still very impressive if they could do it without one. She did consider for a moment finding a Boggart to make it more realistic for everyone in the room but didn't know where the look.

The whole room was covered with wisps of light but there were a few who were successfully doing a corporeal Patronus. Cho had a swan, Hermione had an otter, Ron a Jack Russel terrier, Ginny a horse, Luna a hare, and Seamus managed to form one but it soon disappeared, he was adamant it had fur.

The door to the room opened and in came Dobby with his unusual eight hats on. Everyone was quiet as he worked his way through the crowd, the silver wisps disappeared and the animals created disappeared too.

"Dobby, what're you doing here?" Dahlia asked then was concerned, "what's happened? What's wrong?"

The elf's eyes were wide with terror and he was shaking. His hands fighting together as if he was trying to say something but couldn't, "Dahlia Potter, miss...Dobby has come...come to warn...but house elves have been told not to," he said trying to fight against orders.

Dahlia kneeled before the house elf and reached out to hold Dobby's arms as he began to hurt himself, she said, "Dobby, what happened?"

"Dahlia Potter...she...she..."

"Who?" Dahlia questioned then thought again and asked, "Umbridge?" The look of fear on the house elf gave her the answer, "has she found out about us?" Dobby began to fight Dahlia to get his hands free so he could hit himself but she refused to let them go. She then asked quietly, "is she coming?"

Dobby began to bang his feet on the ground and for a moment, Dahlia thought that he could break his bones in the feet and legs at the force that he was banging them at. Dahlia had to let go of him as she ran to the door and opened it ajar, just enough to see that at the end of the corridor, coming towards them, was Professor Umbridge, Filch, and the Inquisitorial Squad . There was no way they could run without being seen, even with the large majority of them, they would be caught due to spells.

She closed the doors and leaned against them as everyone now looked to her terrified knowing it was the truth, that they were discovered. Whispers then filled the room, all of them nervous about what would now happen to them. All of these people trusted Dahlia to teach them and she said she'd protect and now she couldn't. If found, Dahlia knew Professor Umbridge would try to use their group to get Dumbledore thrown out of Hogwarts and potentially get the students expelled. Not only that, several members of the DA, including the Weasleys, had family members working at the Ministry and who knew if they'd be punished for their actions.

Dahlia knew what she had to do so she rushed past everyone and said to Dobby, "Dobby, I order you to stop hitting yourself. Get back down to the kitchens and if anyone asks if you helped us or gave us any warning, lie and say no. I forbid you from hurting yourself".

Dobby stood hitting himself and smiled, "Dobby thanks Dahlia Potter," he then disappeared.

Dahlia stood and pointed to the wall of the fireplace and said, "everyone get there. Stand beside one another against the wall".

They did as she said but Hermione said, "we need a way out".

"Just trust me," Dahlia said as she ripped the list of members off of the wall and placed it into her pocket before she stood in the middle of the line, "you all believe in me to teach you, now trust me to keep you safe".

Dahlia knew what she was about to do would change everything, her friends would look at her differently and members of the DA may never show up again but she had to protect them. She took a deep breath, let her magic flow out of her fingertips, and mumbled the incantation, everyone saw the purple smoke as it went into a line in front of all of them just as the door opened. They all gasped and looked up to find that Professor Umbridge, Filch, and the Inquisitorial Squad was before them but they weren't looking at them. It was as if they couldn't see them.

"Where are they?" Professor Umbridge shrieked and began to walk all over the room, "they're supposed to be here".

"Someone must have tipped them off," Pansy Parkinson said while the rest of the Squad nodded in agreement.

"Find them," Professor Umbridge said clenching her fists while trying to keep her sweet sickening smile on her face, "if they were notified, they couldn't have gone far. The library, the bathrooms, search them all. Look for anyone out of breath, GO!". The entire Squad immediately left.

"Since when was this room here?" someone asked and when they came into view, it was Steve with Natasha and Clint.

Natasha's eyes immediately went to the symbol on the floor and she shared a look with Clint before glancing to Steve to see that he had noticed. Professor Umbridge said, "it appears a group of students have been breaking Educational Decree number 24".

"Which one's that again?" Clint mumbled to Natasha.

"A club has been formed," Steve said looking around the room. "You sure it's not just a study group, I mean with all the books in here?".

Professor Umbridge stiffened as she strongly disliked the Muggles being in the school to begin with and now they were questioning her. She said, "I have it on good authority, and there's a witness".

"Who?" Natasha questioned.

"That doesn't matter this moment in time, what does is finding those children," Professor Umbridge then left with Filch behind her, the three Avengers then left and closed the doors.

Dahlia, whose arms were now shaking and blood was beginning to drip from her nose, counted to thirty before she said weakly "`mione, go to the door and check if they're gone. Don't worry, they won't be able to see you".

Hermione nodded and stepped past the line of purple light but then noticed some of it stuck with her. She walked to the door before she opened it for a moment, closed it, and said, "they're gone".

Dahlia immediately put her arms down as she collapsed to her knees. Hermione, Ron, Ginny, and the twins rushed to her as Dahlia gasped, "everyone leave, try not to be seen. They'll be checking places close by, try to get back to your common rooms..."

They all nodded and left rather reluctantly, people wanting to ask questions but could tell that Dahlia was too weak to answer them. The Weasleys and Hermione stayed, however, not being able to leave their friend there.

Ron asked, "what the bloody hell was that?"

Ginny hit his arm as the twins began to help Dahlia to stand, seeing that she was having trouble. They put her arms over their shoulders, just as Dahlia mumbled, "not now, I can't explain it now…later".

Hermione said, "let's get her back to the common room before Umbridge comes back".

Ginny opened the door and let the twins walk out with Dahlia as Ron and Hermione walked behind them. Ron couldn't help himself but to ask Hermione as they left the room, "what did she do? That wasn't like any magic I've ever seen. They couldn't see us, and what was she saying? That wasn't any language I've ever heard".

"Shush, Ronald. Whatever she did, it stopped us from being seen but made her weak. She said she would explain later, let's just leave it at that for now," Hermione answered not knowing that hidden in an alcove were three of the Avengers, listening.

As the Gryffindor's vanished from sight, Clint looked to Natasha and said, "looks like you were right about his daughter having an act".

"The fucking saviour," Natasha exclaimed not being able to hide her surprise at the turn of the events.

"Fury's not gonna like this," Steve commented, "we have to get back and tell the others". They nodded then left the alcove to inform their teammates that the girl who was destined to save the world was also the daughter of the man who tried to take it over.

Half an hour later and the clock had just struck past nine. The Weasleys, Hermione, and Dahlia were all sat in the common room with a blanket over Dahlia and a warm drink of hot chocolate. She was still shaking from the use of magic, the blood from her nose now cleaned away. She sat leaning against the side of the fire as her drink was in front of her, the flames keeping it warm while everyone else sat on the couch and chairs. Apart from them, there was no one else in the common room. They hadn't discussed what had happened as they just wanted Dahlia to stop shaking, but even after she claimed that she wasn't cold, they wrapped her in a blanket and placed her in front of the fire.

Dahlia knew with the glances they were passing between one another that they wanted to ask so she decided to break the silence and said, "it's a very old kind of magic, it's in my blood," they all looked to Dahlia, relieved that she finally spoke and they didn't have to ask. "I found out about it at the end of first year and began to learn, but it takes practise and I can't rush myself, just like you can't with your magical core. Too much at once has an effect on you".

"The blood?" Hermione questioned.

"Yeah, that's what happens. I didn't turn everyone invisible, I made an illusion so that no one could see us. I've never done anything as powerful as that. I was shielding almost thirty people and I had no idea how many people would be coming into the room so I had to make it so anyone who walked past would see the illusion. I'm not supposed to do that much. I haven't trained enough for it". Dahlia stared intently at her mug of hot chocolate and said, "one of the first things that I have learned was to levitate droplets of water. I used to use my hand but I could eventually do it without it...now, I can't get a single droplet up".

"What's wrong with it?" The twins asked.

"I've exhausted myself and my powers, for now I can barely use them," she removed one hand from underneath the blanket and held it out to the cup, she focused for a moment and luckily two drops began to float. She smiled but the others gasped and she said, "however, I should be back to normal in a couple of days". She put her hand back down and the droplets followed.

"You said it was in your blood," Ginny said, "does that mean one of your parents could do it?"

They could all tell that Dahlia stiffened as she shifted to face them more and she said seriously, "listen, I need to tell you something but I need you to promise me you won't tell anyone-"

"Promise," the twins said.

"More than that...I need you all to take the unbreakable vow".

"Don't you trust us?" Ron asked offended.

"It's not that," Dahlia said defensively, "they're people in this castle I don't trust, people that would kill me if they knew who I am".

They all agreed and took the vow of silence, Ron slightly reluctant, feeling betrayal that Dahlia hadn't told them before and that she didn't trust them to keep quiet about it. He eventually took it but Dahlia got the feeling it was only because he was afraid of missing out on the secret.

The vows had been taken so she said, "at the end of the school year I'm leaving and I'm not coming back".

"What?" They all exclaimed.

"What about school?" Hermione asked.

"What about the war?" Ron asked.

"I'm leaving so I can learn more about my other kind of magic, I'll still be studying this kind of magic too but it'll be different. It's not safe for me to be here and I don't just mean Voldemort but Dumbledore-" Dahlia answered but it was interrupted.

"What's he done?" Ginny questioned.

"Lies and secrets. The things he tells people may be for the greater good but he's putting others in danger. I need to destroy Voldemort myself and to do that, I need to leave. I won't be alone, my sister and-"

"Sister?" George asked.

"What sister?" Fred questioned.

Dahlia sighed and ran a hand through her hair as she said, "I should have probably gotten to big part of my story first, it would have made more sense. First part, James Potter isn't-"

"Guys, Umbridge wants everyone in the hall," the portrait opened and Angelina Johnson came in and said.

"Why?" Ron asked. "It's almost curfew".

Angelina shrugged and said, "I don't know but she's demanding everyone to go there now," Angelina ran to the stairs and began to shout for those in the rooms to come down and get down to the hall. It was no surprise when most of the people that came down were the younger years.

Walking to the hall, they ran into Cho Chang who said, "she didn't mean to do it. She was just scared, her mum works at the ministry and-"

"What're you talking about?" Dahlia questioned sharply.

"Marietta," Cho said hesitantly, "she's the one who told Professor Umbridge".

"Bitch," the twins said.

"She just-"

"Cho, tell me everything now," Dahlia demanded and grabbed her arm to stop Cho from walking into the great hall.

"She...she told Professor Umbridge that something was happening in the Room of Requirement, that there was a meeting and she...she said your name. Dahlia, something's happened to her. Her face, she has all these pimples and it spells 'sneak'".

"That'll teach her not to betray us," Hermione said smiling confidently that the spell worked.

"You said she only said my name?" Dahlia asked and Cho nodded, "okay, tell everyone in the DA not to admit to anything. They only know me for now, I don't want anyone else getting in trouble," Cho nodded and left as Dahlia let go.

"We can't let you take the fall for us," George said.

Dahlia nodded, "what's the worst they could do, expel me? Remember, I said I was leaving soon, this just pushed my schedule ahead".

They entered the hall and everyone was stood with their houses facing forwards but what surprised them wasn't that the teachers were stood at the front but the fact that the Minister himself, along with Kingsley, Percy, and the Auror Dawlish, were there. Dahlia glanced to a few members of the DA who were whispering and when they caught eyes, they nodded, knowing not to do anything.

While the professors, even Dumbledore, stood back, the Minster stood in the centre and said, "you're all probably wondering why you've been brought in here at this time. It has come to our attention that a group of students have broken not only a school rule but also a Ministry decree. I'm sure you all know how severe this is, which is why I am here...now, we've been given the name of one student involved in this illegal group, but I am willing to give the students who are a part of this group a chance to step forward now. The consequences will not be as severe, simple detention, if you step forward now..."

No one stepped forward for several minutes but everyone seemed to be looking around to see if anyone actually did. Some students in wonder at who were part of this group and others in suspense. Most of the staff seemed to behave in a similar way, except Professor's McGonagall, Dumbledore, and Umbridge. The latter looking more in a thrill of excitement than concerned but that didn't surprise anyone. Knowing such a group existed only proved to show that Professor Dumbledore couldn't control his students.

"Very well," Fudge said and gestured to Dawlish. Dawlish then walked along the centre line of the room, stopped when it came to the Gryffindor students, and pointed Dahlia out before grabbing her arm. Everyone began to whisper as Dawlish brought her forward and Fudge said, "Dahlia Potter, your name has been given for the person responsible for creating this group, the leader. For creating an illegal organisation, you could face expulsion and that means the destruction of your wand".

Professor Dumbledore stepped forward and said, "Cornelius-"

Dahlia interrupted him, "I don't know what you're talking about. I haven't created any organisation, in case you didn't know, I'm doing my O. and they tend to take up most of my time".

"You claim this is the first you've heard of any organisation being formed?" He asked and as Dahlia was about to answer, he held up his hand to stop her and said, "be aware, we have a witness".

"Yes," Dahlia answered, pulled her arm out of Dawlish's grip, and stared at Fudge confidently.

Professor Umbridge then let off one of her usual sweet laughs and said, "you must remember the report I sent you six months ago, Minister. Potter was spotted with a group of students in the Hog's Head. I have a testimony stating that that she was seen and the purpose of the meeting then was to recruit students to join the organisation Potter had created".

Fudge walked away from Dahlia and walked along the pathway between the students and said, "Miss Potter has sealed her fate by not only lying, but by creating this organisation. I urge those of this organisation to step forward and you will not receive the same fate. If you are discovered after this though, you will receive the same fate as miss Potter".

"No one's going to step forward because there is no organisation," Dahlia said and stepped away from the professors and Aurors and stood closer to Fudge, between the students. She saw that some members of the DA were thinking of the deal and she promised she'd protect them, which is what she intended to do. "I admit, there was a meeting to recruit people-"

"Dahlia," Dumbledore tried to stop her but failed.

"But that was before the Educational Decree was put in place to forbid it. We did nothing illegal. After that, no one wanted to be a part of something that would break the law-"

"And the meeting earlier today?" Fudge asked.

Dahlia shrugged and said, "what meeting? No meeting was caught. What Marietta..." a look of shock resided on the faces of Fudge, the Aurors and Professors Umbridge, Dumbledore, and McGonagall. All clearly knowing who the traitor was and Dahlia knew they had spoken before entering the hall. Dumbledore wouldn't be so quiet if he didn't know the full story. "What Marietta probably failed to mention is that-"

"We never said her name," Professor Umbridge said, trying to catch Dahlia out.

Dahlia couldn't help but clench her fists and glare at the toad woman. She knew if her magic was at full strength, it may have come off of her and hit Professor Umbridge in the process. "As I was saying, no one wanted to join because of the rules. Six months had passed and I thought they might want to now. What Marietta failed to mention is this meeting, today, was supposed to be the first. Just to see if anyone was interested in joining, that was all. It never happened though because Professor Umbridge raided the room. The meeting was rescheduled an hour, that's why she didn't catch us. I don't even know the names of the people who would join because the meeting didn't happen. I see that it was a mistake to invite Marietta and the reason I know it's her is because I don't see her in this room".

Fudge glanced around and stiffened, holding his head high as if he wasn't feeling foolish.

Dahlia added, "no one's going to step forward, but that was your plan, wasn't it? You could have handled this peacefully in the headmaster's office but you thought sentencing me to expulsion and having my wand destroyed in front of everyone would make them come forward. A little news, Minister, a lot of people in this school dislike me, think I'm crazy, or both".

"You confess you tried to form a group?" Fudge asked, one last attempt to have her where he wanted.

"Key word: tried. Tried and failed, so are you going to expel a student for failing to break a rule? If that's your wish, I'd happily go and pack my trunk right this moment". Dahlia saw that most of the professors were smiling or trying to hide their smiles as were some of the students. She heard Fred and George joke about the Minister being owned by a fifteen-year-old girl and she was sure the Minister heard it too considering he didn't look pleased. Almost all of the Slytherins didn't look pleased as they had almost gotten rid of the Girl Who Lived , but some also noticed the sneaky tactics and words she used were very cunning. After all, she was Loki's daughter.

A side door to the front then opened and the Avengers slowly walked in, Thor hiding something to his side. They gestured to Professor Dumbledore and he walked towards them so that Thor could whisper. Dahlia definitely didn't have a good feeling about it, especially since Thor's hammer was at his waist, Clint had a bow and arrows, and Natasha had a hand on her waist where Dahlia knew there was a concealed gun.

Calling all the children to the Great Hall was the perfect time for the heroes to investigate. They couldn't tell Odin or even Fury that they suspected Dahlia Potter if they had no other evidence. They waited outside the Gryffindor common room until Dahlia and the others left for the hall. Approaching the painting, the Fat Lady still needed a password even though they were professors. Luckily, Natasha knew it and said, "Mimbulus Mimbletonia".

The Fat Lady nodded as she opened the doors and said, "welcome, Professors".

While the men waited downstairs, Natasha went to the right staircase leading to the girl's dormitories. It wasn't that the men couldn't go up, the spell recognising them as professors wouldn't allow the staircase to turn into the slide, but they still felt awkward, even if it was Loki's daughter, searching through some teenage girl's belongings. For a few minutes, they waited in the common room, some of them sat while Thor paced wanting to find out if Dahlia Potter was truly his niece like the Captain, Widow and Hawkeye had told him.

When Natasha finally came back down, she held a wooden box in her hands. Everyone stood and walked closer as she said, "found nothing suspicious until I noticed the bottom of her trunk had a hidden compartment, then out came this. I can't open it but it's got writing that looks like yours Thor".

Thor took the box into his hands and everyone could see the look of recognition that he now held. "Wanna tell us what it means, Point Break?" Tony asked.

Thor gulped as his hands traced the writing in the centre then to smaller writing around the edges. He said, "my mother has one just like this. In the centre, it translates to family. Around the edges, however, I cannot translate fully, my friend, because it is magic".

Clint sighed and said, "please tell me you mean Hogwarts magic and not Loki magic".

Thor nodded, "magic outside of this realm, Aesir. The writing is in old Norse, my language and the writing around the edges is a spell, linking this box to a specific person or their magic. No one can open this box but the person it is linked to".

Bruce shifted uncomfortably and said, "so she doesn't only have witch magic by also Loki's".

"And she's currently in the hall," Steve said, "with the rest of the children, staff, and Ministry officials who don't believe her that a man trying to kill her is back. We should get down there, now".

They all swiftly moved to the portrait to leave and as they rushed downstairs, skipping steps along the way, Tony said, "like Point Break said, it opens to her only. If we can get Dahlia to touch the box, then it confirms who she is".

It didn't take long for Dahlia to figure out what Thor was hiding. The quick glances that the other Avengers sent her way was different than any before, as this time it was more vigilant, as if assessing a threat. She then saw Dumbledore looking at her as if he had been told something distrusting and that's when she finally saw her box. The box that held memories of her mother, every precious item she had was hidden where she thought it would be safe. Clearly not.

Dahlia looked back to the Minister, needing a way out immediately, "I assume that if you don't want me expelled than at least I'll be suspended for trying to form a group?".

Fudge stumbled a little as he said, "yes, yes, of course. A simple lesson needs to be learned. A two-week suspension I think for attempting-".

Dahlia nodded, "of course, I'll go pack my trunk".

She turned to leave but Thor said loudly, "Dahlia Potter, we wish to speak to you".
