Disclaimer: Only saying it once. I obviously don't own Harry Potter, I mean it's called fanfiction for a reason.
I only own what you don't recognize.
The slow tapping of fingers against wood could be heard in the living room of Twelve Grimmauld Place. The sound that was starting to become extremely stressful for Molly Weasley, who was trying to clean some of the furniture that was covered in dust.
Behind her back was her younger son, looking at her movements attentively.
"You still haven't answered our question, mum." He said with narrowed eyes, looking at his mother suspiciously. Since last week, a few members of the Order of The Phoenix, his parents included, had been acting a little bit too weird for his liking. They were ignoring their questions more than usual, as if there was something bigger to hide this time.
"What?" Molly swallowed. "Sorry honey, I have to check the food. We can talk later." She walked to the kitchen as fast as she could, with Ron following closely behind.
"No mum, not later, now. What's going on? You've been avoiding answering our questions more than usual and we're not even asking about the big order business! We just want to know if something worse than the ordinary has happened! Just answer that!" He said, exasperated.
"Except it is big order business..." Molly whispered to herself while looking at the food. She let out a tired sigh and turned to look at him. "Ronald..." That catched his attention and he looked at her. Really looked at her. She appeared to be worried and worn out. This is bad, he thought. "Believe me when I say that we can't tell you. And I mean it. This is very important and you will know what's about in a few hours at most, but right now, we really can't tell you anything about it."
"Why?!" He asked, desperate. Molly closed her eyes for a second before looking at him in the eyes.
"Because I..." She paused and took a shaky breath. "Because we made an Unbreakable Vow." He didn't know what kind of answer he was expecting to get out of her but that one was definitely not it. He couldn't speak, he could just look at her with his mouth slightly open. When he was about to bombard her with questions, she spoke. "Now go, I have to finish this." He didn't move. "Ronald Weasley, get out of here. That is an order."
He blinked a few times, closed his mouth and left the room.
"An Unbreakable Bow? Merlin..." George said while running a hand through his hair. "This is huge."
"What do you think they vowed? Maybe they are protecting someone..." Hermione added while biting her lip deep in thought. "I mean... it makes sense. They can't say anything because they would die."
"Don't be so bloody cold about it. We're talking about my parents and possibly brothers dying here!" Ron cried as Hermione rolled her eyes.
"They are not going to die, Ron. They are not stupid and one does not make an Unbreakable Vow knowing they could break it easily." Ginny said, successfully calming her brother. Ron just sighed and rested his head on the mattress behind him.
"Whatever, we are going to know today anyway. That's what mum said, isn't it?" Fred asked entering the room after trying to listen if any of the adults said anything about the subject without succeeding. Ron nodded.
"Well... everyone is already here. This has to be it... right?"
"Should we go-" Hermione's question was cut short by Molly calling for them to go downstairs.
They looked at each other in silence and made their way down slowly. This time they were actually nervous, because something was telling them that what was about to happen was something they could not expect.
Sirius, Molly, Arthur, Remus, Tonks, and Dumbledore were the only people in the room. The latter was a surprise to them, and his presence only helped to make them feel even more nervous.
"Uh... well... what we are about to..." Molly stammered but Albus stopped her, receiving a grateful and relieved smile from her.
"It's okay Molly, let me explain. Would you please take a seat?" He asked slowly, as if trying to soothe their nerves. It wasn't too helpful because the adults looked rather worried, and that was definitely not a good sign. Albus sat on a chair so he could face them all directly.
"What we are about to confide you, we do it because more than once you have shown that you can be trusted. However, on this particular matter, it's not only about trust, it's also about the danger in which we could put very important people, if the situation is not assessed with the upmost care. What I'm saying is that you will be told an important secret, and if you are willing to keep it, you will have to make an Unbreakable Vow. If you are not willing, your memory of the moment will have to be erased. Are you okay with this?"
The kids looked at each other and nodded. The sound of the door opening made them turn their heads at the same time. Three people entered the room. Two were unknown to them, but the third one made them really wonder what the hell was really going on.
Severus Snape stood in the room with two women, one that looked at least five or six years younger than him, and one that had to be at least seventeen.
"You are all aware of who Professor Snape is, I'm sure." Albus said with a smile on his eyes. They looked at Severus with frowns on their faces, and it was almost possible to see him resisting the urge to roll his eyes.
"I'm Juliana." said the older woman with a very slight accent none of them coud recognize. "And this is Cassandra."
"Cassie. Just Cassie. I like it better." The younger girl said as she waved at them with a small smile. Five pair of eyes turned to look at her, their attention focused completely on her for the first time.
In about five seconds their minds recognized that this girl had jet black hair that was way too familiar, and definitely didn't match with the color the woman standing next to her, who was obviously her mother. This girl, Cassie, did have her nose, mouth and her body shape, but not her hair and... her eyes. They all knew those eyes. How could they not? Hell, every student in Hogwarts knew those eyes and probably more than a half were terrified of them.
Those were, without a doubt, Severus Snape's eyes.
This is were the author notes go, right? Um, okay. So I decided to make this story because it's something I wanted to happen and obviously no one was going to make it... but I'm really new at this writing thing and english isn't even my native language (it's spanish). So if any human being reads this and thinks "Omg this is wrong" and wishes to correct me YOU ARE DEFINITELY WELCOME. DO IT.
Also, this story is not intended to be super deep or long, I actually want it to be short and pretty shallow just to calm my need to see this happening. It's obviously AU, and the main focus is the relationship between Cassie and Fred, and her mother Juliana with Severus.
