Many people thought that Abigail Sciuto was just an over the top, over caffeinated, eccentric, gothic forensic scientist for NCIS in Washington D.C, but she knew deep down that she is so much more than that. Abby is a witch. But she is not the only one that was keeping secrets at NCIS

Chapter One

"Abbs, have you finished the report yet?" Gibbs asked walking into Abby's lab, to find it empty. "Abby, where are you, I need the forensic report for Jenny. Abby, where are you hiding?"

Abby was once and for all going to sneak up on Gibbs, ever since she started working for NCIS she had tried to get the jump on him, but it never worked. He always knew where she was. As Gibbs started to search the lab, Abby got prepared to pounce from her hiding spot.

"Abby, you really need to stop these attempts to sneak up on me, I know that you're in the ballistics lab."

"Gibbs, how do you do that it's really weird." yelled Abby as she jumped out from her hiding place under the table in her ballistics lab.

"Abby, I just know you that well, come on since you are finished work for the day, let me buy you some dinner. Ok" Gibbs just smiled at her with his trademark half smile.

"OK, Gibbs that would be nice, and I haven't seen the team all day so I will have to go up and say bye to them before we leave. You go up to the bullpen and I will meet you up there I just have to shut down my lab for the night."

"Ok Abbs."

When Gibbs walked in to the bullpen, DiNozzo and McGee were getting ready to leave for the weekend, but Gibbs couldn't see Ziva, when he and the team noticed Jenny approaching, they started to get worried.

"We don't have a case, do we director?" McGee's face dropped as he asked, he had plans to catch up with his sister this weekend.

"No Agent McGee, you don't. You guys have been on call every weekend for a month. I just came down for the report from Gibbs, and I am expecting a visitor, and I thought I would come down here to meet them." While Jenny was explaining no one noticed that the elevator had opened and a woman with vibrant pink hair was standing behind Jenny.

"Well that's rather nice, Director Sheppard, much nicer than some of the other agency directors I have met over the past couple of weeks." the woman said with a very obvious British accent.

"Well hello and welcome to NCIS, Special Agent Nymphadora Lupin, I am Director Jenny Sheppard. Let me introduce you to the Major Case Response Team," Jenny pointed to the team and introducing them. "The leader of the team, Special Agent Leroy Jethro Gibbs," when Jenny said this, Agent Lupin approached and shook his hand.

"A pleasure to meet you, sir."

"Don't call me sir, just Gibbs is fine. A pleasure to meet you too Special Agent Lupin"

"Please call me Tonks, everyone does."

Jenny continued to introduce the team, "Special Agent Tony DiNozzo and Special Agent Tim McGee." As they were introduced, Tonks approached them both and shook their hands. Ziva then walked into the bullpen, so Jenny introduced the newest arrival to her visitor, "and here we have the newest agent on Gibbs team, Probationary Agent….."

Tonks turned and looked at Ziva, and then without warning launched herself at Ziva into her arms and gave her a giant bear hug.

"Ziva! What are you doing here?"

"Tonks, I could ask you the same thing, Tonks … Nymphadora! I cannot breathe"

With this they let go of each other, completely oblivious to the stares they were getting from the rest of the bullpen, then Tonks punched Ziva on the arm "Ziva don't call me Nymphadora, you should know better," the annoyance and anger radiating in her voice, but before anyone of them could voice their confusion at the situation Abby walked in and got one look at the visitor and ran for her.

"Oh My God, TONKS! What are you doing here?" Abby yelled as she almost crash tackled Tonks into Ziva.

"Oh what a day for reunions," Tonks said under her breath "Hi Abby, I didn't know you were back in America. Ok, Abbs I need you to let go of me, I am having trouble breathing Abbs, let go…. Like now!"

"Sorry Tonks, it's just I haven't seen you since Teddy's naming day and what was that like, 10 years ago now."

"Yes sorry I haven't had the time to catch up, Teddy just turned eleven and is about to start school, and without Remus to help him through what he will need to do to control, his...um…little furry problem, I am having trouble trying to do that and with none of the marauders left to account for how they did it, and I am helping Harry with the new order, and work hasn't been any easier. So yep, my life has been a little hectic…"

Again, the two women were completely oblivious to the other team members.

"Wait, how do you two know Special Agent Lupin?" Jenny was the first to snap out of the confusion, and try to get some answers.

Abby was the first to answer, "Well we went to Hog... a special boarding school in Scotland together. We have known each other since we were 11."

Ziva responded next, not really taking in what Abby had just said "Well I know Tonks from work when I was with Mossad, we also went to the same school, but I was a just starting when she had just left."

Abby and Ziva looked at each other, what had just been said finally registering in their heads. They stared at each other, stunned. Tonks, standing in the middle of the two stunned women looked back and forth between them, finally realising what had just clicked into place in their heads.

"Well, oh fuck." Tonks swore under her breath knowing them both to well, and knowing what was coming next.

With that Ziva and Abby yelled at each other, at the same time.

"YOU WENT TO HOGWARTS!"

Oh fuck, I really am in deep shit now. Tonks thought, as she watched Ziva and Abby both faint.

"Did you guys have to yell that loud? You are lucky that the building is empty," Tonks almost screamed at their unconscious bodies, before turning to Jenny, and trying to hide the annoyance in her voice to look professional "Director, can we all please continue this in your office or somewhere not quite so public, I am going to have to brief the whole team now, is there anyone else on this team?"

Jenny started to lead to group to her office, while she watched Tonks trying to drag both Ziva and Abby with her, "Well the other than Ducky, the medical examiner and his assistant Mr Palmer, no one else really works with the team full time, I believe they are both still in Autopsy if you would like me to call them."

"That would be most helpful, now can someone give me a hand with these two, I think they are in shock."

Tonks gave up trying to drag the girls with her, and Gibbs picked up Abby started to carry her to Jenny's office, while Tony did the same with Ziva. Jenny got out her phone and call down to Autopsy.

"Ducky, I need you and Mr Palmer up in my office ASAP; you have to be briefed on something."

Once the group had reached Jenny's office, Ducky and Mr Palmer were waiting outside. Ducky expression turned from confusion to worry when he saw Tony and Gibbs carrying Abby and Ziva.

"Jethro, what happen to the two of them?" Ducky was examining them within seconds.

"Don't worry Duck, they just got a bit of a shock, although I don't know why. Would you like to tell us what is going on Tonks?"

Tonks looked around the office, trying to figure out what to do.

"Well Gibbs, Tony put the girls on the lounge over there and I think they might want to explain this to you themselves, it is not really my place to tell their secrets."

Tony had a shocked look on his face "How do you think they can have a fully conversation with us, they are not even conscious!"

Tonks reached down into her boot, and pulled out what seemed like a stick "Well then we will have to fix that then, wont we"

Tonks waved the stick over Abby and Ziva, and they started to come to.

"Tonks….." Abby said as she looked around, trying to figure out where she was.

"Hey Abbs, I haven't told them anything yet, I thought that you and Ziva might want to do that."

"Ziva…?" remembering what had happened in the bullpen, Abby turned to Ziva, who was starting to wake up. The two looked at each other and then at Tonks, as if the funniest thing had just been said, the three girls started laughing.

The whole team, who had never seen this from Ziva, their ninja, looked at both of them with confusion. Gibbs was the first to break up the laughter

"What is going on here? Ziva, Abby. I want answers. Now!"

"You have already said way too much for a muggle to hear, and they all saw me wake you up. But since I was here to tell Director Sheppard anyway, you may as well go and tell them everything. But you are not getting any help from me, you started this, you get to deal with it."

Ziva and Abby both agreed, and then stood up from the lounge and took the few seats that were left at the conference table.

"I can't believe I never noticed Ziva. I mean that, come on I really should have noticed. Can I please ask you a few questions first before we tell them."

"Fine Abby, as long as I can ask the same questions of you."

Abby nodded at Ziva.

"OK first. Muggleborn, Pureblood or Half-blood?"

Ziva thought for a second, she never really told anyone her blood status, as she was a Pureblood, most people thought that she would be a blood purist, she wasn't, but some people where. She didn't want Abby to think she was one of them.

"Um…. Pureblood, but I am not a blood purist, at school my best friend was Muggleborn."

"OK one more question. What house?"

The team looked confused, they were all thinking, what is this talk about blood and houses? What the hell are they talking about?

"I am a proud Gryffindor, and always will be. Now your answers, Abby."

"Well I'm a Half-Blood, my dad's side was muggle's but mum loved him so she went with her heart, and one of my best friends at school was also Muggleborn, but unfortunately, she was murdered about 27 years ago. As for house, I am a proud Ravenclaw all the way. Now I think we should start explaining to them what is going on."

As Ziva agreed, Gibbs was getting impatient. "Yes, now what is going on?"

Abby looked at Ziva, who nodded and allowed her to start the explanation, although Ziva had been an accepted member of the team for eight years now, they all knew Abby longer, so she thought that it may be easier coming from her.

"OK Team Gibbs, please don't freak out, and if you want proof I am sure between Ziva, Tonks and myself we can make that happen, but please don't start to freak out and…"

"Abby, just get on with it. I actually came here for a reason, and would like to go home sometime in the next decade." Tonks said from her position on the lounge.

"OK everyone, Ziva, Tonks and me are all witches, as in full on magical witches."

The looks Abby was getting from the team, told her that they wanted her to continue, but they didn't trust their mouths to speak the words aloud.

"OK let me explain my life, it help you understand. I am a Half-Blood, which means one side of my family has a magical background, and one side of my family has a muggle background, muggle being non-magic people. My mum was a witch and so was her whole family, going back generations, she met my dad and they fell in love, her family accepted this and allowed them to be married. My mums family has always had the last name of Scuito, it's a powerful name in the magic community, and when dad married mom, he understood her keeping the name, before they discovered I was magical, my last name was Bennett, when I was eight I got really annoyed at my brother, and sorta… blew up our kitchen. When mum realised, she and dad agreed to change my last name to Scuito, so I could carry on the heritage of the name. When I was eleven I got my letter from Hogwarts, which is a school that teaches young witches and wizards how to control their magic.

I went to school, and was sorted into Ravenclaw, just like my whole family. While I was there I met people who I am still friends with today and people who I wish I was still friends with. I met Tonks, who was in my house, and other than her most of my friends were in Gryffindor, I did have one friend in Slytherin. But I heard that he had died in the war."

At this Tonks grew a guilty look on her face. Abby didn't notice, but Gibbs and Ziva did.

"My friends in Gryffindor, were James Potter, Sirus Black, Lily Evans, Remus Lupin" Abby noticed Tonks, Ziva and even herself felt sad with the mention of this name, but then Abby and Tonks faces grew fierce and angry with the last name" and Peter Pettigrew"

With the mentions of all the names, the sadness Ziva displayed disappeared in a second as she almost screamed in surprise, scaring everyone else at the table "You were friends with Lily and James Potter. Wait a second, you are that Abby?"

Abby looked down to the table, mumbling but her voice getting stronger as she continued "As in the Abby that was Lily's best friend, and Harry Potter's Godmother. Yes I am that Abby. I felt horrible when they were killed, and I wanted to take Harry to live with me, to grow up in a happy house, somewhere he knew who he was and wasn't abused by Vernon that tub of lard and that prim bitch, Petunia. Who couldn't even raise her nephew in a happy home."

Standing and pacing around the room, everyone could see Abby was getting angry now. Tonks could feel the magic in the room and knew she had to calm her down, before Abby did something she would regret later, like blowing up the building. Tonks and Ziva looked at each other, knowing what could happen. They both jumped from their seats and ran to hug her and calm her down.

When they managed to calm her, she sat back down, cuddled closer to Gibbs for comfort and continued her story.

"But Albus Dumbledore, the headmaster of Hogwarts, said I was in danger too. He said that the only safe place for me was America, because it hadn't been affected by the war, so I came here, went to a normal collage, got my degree and got a job here. About ten years ago, I got a letter from Tonks telling me the war was finally over, and I could come home. I did and met my godson, Harry. I told him who I was, and why I never took him in, I told him I wanted to. He was angry at first, but I understood that. I let him yell at me and I let him cry on my shoulder when he calmed down. He understood what it was like, he had just gone through it himself, and so he accepted me for who I was. The first night he didn't want to yell at me we stayed up almost all night, I told him stories about his mum and dad, his godfather Sirus and their best friend Remus. I told him about Severus, his mum's childhood friend, and a very brave man, who was my friend in Slytherin. Tonks and I were the only people left living that knew his parents, everyone else had died from one of the wars, so we told him about them."

Tonks started looking guilty again, Ziva noticed and knew she had to bring in up later.

"Whenever I take my holidays, I go home and visit Harry and his family. He and his wife have got a little boy, James. He is named after his grandfather. He is so cute and I love him, this Christmas they were planning on coming to America to visit me. I can't wait, and hopefully, now you guys know about me, I can bring them here and introduce them to my other family… you guys. I have told Harry and his wife, Ginny, all about you. They said that one day they want to meet you guys.

Well that's my life, the way it actually happened. Not that load of bull I came up with for my file."

Tony looked completely freaked out, Ducky looked more than intrigued, Jimmy was fascinated, but Jenny and Gibbs looked like they always did, calm.

"Anybody got any questions? Someone please say something… Gibbs?" there was sadness in Abby's eyes as the man she saw as her father, just looked into her eyes, the calm was gone. It was replaced with something Abby didn't want to see… disappointment.

"Gibbs…? Please don't give me that look." Abby was almost crying, trying to get the words out.

Gibbs didn't know what to feel, he was disappointed that she had never told him this, but at the same time he was proud. Abby was like a daughter to him, and although he didn't encourage anyone keeping secrets from him, but he understood why she did what she did. Abby had a horrible past and the courage that it must have taken to tell them made him so proud of her.

"What look, Abbs?"

"The disappointed one. Please don't do that, it's breaking my heart to see you looking at me like that." the tears flowing down her face now, but she didn't care.

"I am not disappointed. Sorry if that's what you thought…." he went to continue, but was stopped by a yelling Abby

"Don't do that! It scares me so much when you break your own rules." she waited a second before registering what he had said.

"If you aren't disappointed, then how do you feel?"

"I am so proud of you Abby. I was disappointed that you kept secrets from not just the team but from me, but I understand why you did. You have had a tough life, and I see now how tough, and it takes a lot of courage to tell you story like that. I am far from disappointed."

Abby jumped into his arm for a hug. Jenny watched and she knew deep down that Abby was telling truth. But being the investigator she was, and the fact that she had always believed in magic, Jenny wanted to see some magic performed. "Abby, I am sure I speak for all of us, we are all proud of you. As much as I would like to hear about Ziva's life in magic, I was wondering if you would show us something first. I am sure everyone would."

At this Abby's mood picked up, she looked at Ziva who nodded with approval.

"We can all meet up and talk about my life tomorrow. Right now, I think you should show them what we can do."

"Yes, I would love to show you guys." she looked at Tonks, suddenly remembering the laws. "Oh, Tonks can I, can I, can I please show the something?"

At this Tonks laughed, "Abbs they have seen me revive you and Ziva. You just told them about your life, you can show them anything you want, they are your friends."

"And the ministry can't do anything?" Abby was almost jumping up and down.

"If they were going to don't you think they would have done it when I revived you two." Tonks was still laughing at Abby, trying to talk between the laughter that she was unable to control.

"Can I show them my Patronus. I have changed it since you saw it."

Tonks looked at her. Her laughter ceased and a look of surprised and sadness was in its place. "You changed yours. It was really difficult to change mine. But I did it for personal reasons."

Ziva's usual mask to hide her emotions broke, she was almost in tears "You changed it because of Remus, didn't you?"

"Yep, in the first year of the war, it was hard but I did it. It's a memorial to him."

Abby was tearing up, "Sorry to bring it up. I know you loved him loads."

"Yes I did, and I always will, but I am able to remember him now, without breaking down. But now I want to see what you have changed it to."

"OK, Team Gibbs, don't freak out."

Abby thought long and hard about the memory to use. She hadn't cast a Patronus since she left Britain to move to America. She thought and thought and then found the happiest memory in her whole life. She stood up, took her 11 inch, oak wand with Dragon Heartstring core to cast her spell.

"Expecto Patronum!"

In a flash of white a giant white, translucent Hippo, that looked just like the stuffed farting Hippo, Bert. He had the spiked dog collar and the ballistics earmuffs.

Tonks sitting there laughed as she thought, Just like Bert. Just like the day I gave him to her.

But as fast as it appeared, it disappeared in a black puff of smoke, and a scream erupted from Abby's mouth. As everyone went to cover their ears, Ziva and Tonks went to grab Abby who was falling to the floor. Tonks looked worried, but Ziva looked like she had seen this before.

"Ziva, what is happening to her? I have never seen this happen before, a Patronus is meant to protect a person from fear, not cause it. What the fuck is going on?" Tonks was yelling now, scared because of what was happening to her best friend.

"This has happened to me before. Tonks the memory she used, while it may have been her happiest, it also somehow brought forward her most horrible memory. She will be fine, I just need some chocolate for her when she wakes up. Tony go and get some chocolate, now!" Tony ran out of the room thinking that no one would mind if he 'stole' the chocolate from the break room.

Ziva knew she needed to move Abby on to the lounge, so she could get her to relax.

"Gibbs, can you please put her on the lounge? She needs to get comfortable and feel safe, so she can wake up."

As Abby was lifted onto the lounge Tony came in with the chocolate for her.

"DiNozzo. Did you pay for that?" Jenny with a strict look on her face looked towards Tony.

"Of course Director. I don't believe in theft in the workplace." Tony responded, with a smirk and sarcasm thick in his voice.

Tonks looked at Tony, hearing the sarcasm in his voice, but left it. Looking back from Jenny to Abby, she figured she would have to get everyone out of here before she could talk to Jenny, and she knew how to get them to go home.

"Director, I need to brief you tonight, but even though I will need this teams help, I need to brief you in private. We can all meet back here in the morning to hear Ziva's story and for me to brief you all." Jenny nodded in agreement, and dismissed the team.

As Gibbs and Ziva went to pick up Abby and take her home, but Tonks stopped them.

"I will take her home after talking to Jenny. I don't think she will wake until the morning, so I will take her home and make sure she is taken care of. Don't worry Ziva, I will make sure she eats the chocolate when she wakes up. And I won't let anything happen to her Gibbs." Reluctantly both Ziva and Gibbs agreed with Tonks, even though Ziva knew Abby would wake up in about an hour or even half of that, but she trusted Tonks to know she knew what she was doing, and both Ziva and Gibbs knew that Tonks would keep her promises of keeping Abby safe.

After about half an hour of saying their goodbyes and see you tomorrow's, everyone finally left and went home, so Tonks and Jenny sat down to begin the briefing. After an awkward silence, Jenny thought she would get the ball rolling so she could go home tonight, as because of a big op this week, she hadn't been home in three days.

"Well when I was told that a member of the British government was coming to brief me, I never believed that this would be what would happen. Would you like a drink Tonks? Cause I sure as hell do."

"Umm yeah thanks. If you have any bourbon that would be great."

"Just like Gibbs… Can I have one too, please?" a weak voice answered from the lounge. As she started to sit up, Tonks threw her the chocolate and she started to eat some.

"Abby. I thought that you said that she would sleep till the morning Tonks." Jenny sounded pissed but grabbed an extra glass, pouring the bourbon and handing a glass to Tonks and Abby, before taking her own. They all had a drink and continued.

"Yeah well I lied. I knew she would wake up soon and so did Ziva. But what I need to brief you about, Abby should know to. It does concern someone she cares about."

With this Abby shot up from her position on the lounge, the chocolate discarded onto the floor and she started to look worried, someone she cared about. It could be any number of people, Harry, Ron, the whole Weasley clan, Hermione, James, some of the professors at Hogwarts.

"Who is it Tonks. Don't hold out on me. If someone I care about is in trouble or hurt, you need to tell me or so help me…." Abby was angry and the electricity in the room had just risen ten-fold. To Jenny it felt like electricity, but Tonks knew better, it was the magic resinating from Abby, and it was worse than before. Tonks jumped up and grabbed Abby by the shoulders and pulled her into a massive hug, she held her there waiting until her breathing evened out.

"Abby calm down, please. We need this building here in the morning. NCIS headquarters blown up is not something I want to explain to the minister. I will tell you but you need to stay calm. Please do not get pissed at me for not telling you sooner."

Once Abby's breathing settled, Tonks looked at Jenny, who nodded and gave her permission to start with the brief. Abby sat down and waited for Tonks to start.

"OK, well you already know about magic now, which takes like an hour out of the briefing. So let me get to the part where I need your help. After the war ended, there were many casualties, and many people reported missing. Not all of the bodies have been found, but when there is magic involved that doesn't mean much. One of the bodies that was expected to be recovered, wasn't. At the time most people just thought that his body had been recovered by people loyal to him.

But after some evidence was uncovered and was left at the Ministry of Magic, we then suspected that this person was actually alive. Now we have our own solid proof that this person is alive and well. The reason this should concern NCIS, is that this person moved to America and through fake documents he joined the US Marine Corps. To be honest as much as many people didn't like him, he is missed. We want him back, we need him back…." Tonks trailed off and looked to the floor. "I need him back to help me and Teddy."

"Great, we would love to help you Tonks, but you still haven't told me why you need this person, or what he can do to help you and this Teddy." Jenny had gone into director mode, and she was even surprised by the fact that a US Marine was in the corps on fake documents but she didn't care, well not as much as she should have been.

"Wait Tonks, you are not here on orders of the Ministry. Are you?" Abby sounded concerned that her friend would be a loud to be on a mission to hep Teddy.

"Well I sorta am. I am here under the orders of the Ministry to brief Director Sheppard on the existence of magic. But, the other thing the Ministry doesn't know about. I found the evidence and found the information. I need to help Teddy and this man is the only person that can help."

Getting annoyed that none of her questions had been answered Jenny stood up, walked over to refill her glass, when she sat back down she thought her questions would be better answered individually.

"OK, so we will still help you. A man in the Marine Corps on fake documents is an important issue. But who is Teddy?"

"Oh, well thank you for the help. Teddy is my son. His father, Remus Lupin was attacked when he was a child by a werewolf and unfortunately Teddy has some of the wolf genes. Not quite as bad as Remus and other werewolves but still, it is a horrible thing. The man that I am looking for has apparently created a potion which is a lot like Wolfsbane, which gives a werewolf to retain their humanity when they are transformed. However the new potion, has the ability to strip a person of the werewolf gene, and this was only possible because of ingredients found in America. I don't want Teddy to go what his father went through at school. I want him to have a happy childhood and a happy life. I want his life to better than mine and his fathers was, is that too much for me to ask for…." Tonks had tears in her eyes. As Abby pulled her in for a comforting hug she completely broke down, crying for many reasons, but her sons happiness and her lost husband were the main reasons.

"Tonks, sweetie. This is a great advance and is a great thing for not only Teddy but for all werewolves, who do not want that fate. The happiness of your son is not too much to ask, after all you and Remus went through I understand where you are coming from. But for us to find this person we need a name or picture. Tonks what's this guy's name."

"Yes Tonks for us to find this person, we need a name or picture of some sorts. When we find him we can bring him to you and help your son." Jenny said with a strong voice, but it was clear that she was on the verge of tears

"Thanks. The reason I came to you is, one this guy is now a marine, and two… Abbs, you know him."

"So this is the person I care about being involved. Who is it?"

"Please don't be mad, and please believe me. Abbs, its Severus. He didn't die from Nagini. Abbs, Snape is alive."

To say that Abby was shocked, was an understatement. She couldn't tell how she was feeling, overjoyed, scared, excited and anger were the ones boiling to the top. Severus Snape was…ALIVE. Her Sev, her best friend, the one she cried the most over after the war, he was alive.

"Snape...alive…my Sev" Abby trailed of, then collecting her thoughts she jumped out of Tonks embrace, and then with a loud pop, she was gone.

"Where the hell did she go Tonks!" Jenny yelled. Her forensic scientist, not only was lost for words which was a first, but was gone. "She was there and now she is gone, where did she go Tonks? Was that some kind of magic?"

Tonks started to rid herself of tears, knowing she had to find Abby. "Merlin's Beard! I knew I should have told her that at home. Jenny what you just witnessed is called apparition. It is a process wizards learn when they turn 17. It is like teleporting. Stay here I will go and find her and be back soon." Before Jenny could get a word in Tonks stood up and with a wave goodbye and another pop, Tonks was gone.

"Merlin's Beard….? What the fuck?"

TBC…
