Rossi's Daughter

The Past

"Come with us, daddy!" The little brunette cried, as she wrapped her arms around her dads neck, as he lifted her up in his own arms.

He waited until she was looking at him, before he said anything else to her, "Peanut, you know that I can't do that, I need to fight bad guys here."

"I want to fight bad guys with you," She looked back to where her mom, and new step dad were standing, "Mommy, I want to stay with daddy."

"David, do you have to get her so emotional before our big flight?" His ex-wife accused, taking her daughter back into her own arms, "We need to catch our plane."

"You're moving her over seas, without even given her the choice," David reminded, watching as his daughter tried to fight against her mother, to get back to him. "Jane, let me talk to her alright? I am her father, for crying out loud."

Jane looked back at him, before setting her daughter back down, "You have ten minutes, David."

His daughter ran straight into his arms, "Daddy, I don't want to leave you."

He knelt down, and took a hold of her small hands, "Mia, you need to go with your mom, and Alfred, so they could be protected. I need to protect the people here, you need to protect them, alright? You're going to be my 'little Agent'. I will call you once a week, and you'll be able to stay here during the summers, I promise, Peanut."

"Okay daddy," She kissed his cheek, before hurrying to where her mom, and step dad were standing, taking both there hands as they made there way to there flight.

FBI Headquarter

'Dear Daddy,

I know that it shouldn't concern you anymore, since you, and mom, were divorced for almost ten years, but I really don't know what to do with everything. It's my fault that mom, and Alfred, were killed, because I told you I would look out for them. Some one had broken into there home, while I was at my boarding school, and they were slaughtered in there sleep. We caught the cooperates, but everyone is asking me questions about where I want to bury them, or if I planned to cremate them.

I thought that once we won this war, than my parents would be safe, then I would be able to restore there memory. Sometimes I feel that if I never discovered that I was a witch, than none of this would have happened to the ones I loved, and than again I never would had met my best-friend. Harry, who tries to be supportive of me, but they honestly don't understand, what all I have to do to bury them. Sure Harry lost both his parents in the first wizarding war, but he never really had to plan for a funeral, and here I am needing to do just that. Please use this plane ticket, which I enclosed in the letter for you, but I truly understand if you're needed there.

I think after this is all over, I would very much like to return, to the only person that will ever be considered home. If you would allow me to live there. I love you so very much!

Love,

Mia

David stared at the letter in his hand, as he sat in first class, waiting for the plane to finally land. He still could not believe how supportive the team was, when he explained that he had to go help his daughter plan a couple funerals for his ex-wife, and step-dad. He even couldn't believe that his daughter would think, that he wouldn't even want to help her, just because her mom wasn't married to him anymore. She was still his daughter, and it broke his heart thinking that she didn't realize, that he would do anything for her.

"Sir you need to put your seat-belt on, we're getting ready to land," One of the flight stewardess instructed, before turning to the other passengers.

"Thank you," He nodded, even though she had already left. He looked out the window, as they reached the landing pad, where he knew his daughter was probably waiting for him. He hadn't seen her since she was sixteen, because she had written him about the war, and how she felt that she needed to be there to fight for other muggle-born's, who had similar backgrounds. He had written her, sharing how proud of her he was, for doing something so big for the future of her world. They had become closer after she found out she was a witch, because he allowed her to be herself at his home during the summers, and she had explained how her mom, and Alfred, would make her lock her trunk in the garage during the holidays, and part of summers she was with them. She had even thought about moving in with him when she was fourteen, but by then the second war had started, and she felt like she needed to stay where she was.

He spotted his daughter, almost as soon as he exited the terminal, and noticed how her eyes scanned everything around her. She would shift away, when someone would accidentally brush her arm, or when someone dropped something behind her, it had made her jump. He could tell that she had been in a war, because he had behaved the same way she had when he was in the military, and it made him want to hold her forever. He didn't even realize that he had approached her, and was already hugging her, until he felt arms wrap just as tightly around him.

He kissed her hair, as she cried against his chest, "It's alright, Mia, we're together again, Peanut."

She stepped away a little, and gently patted his cheeks, registering that he was really real. "I am glad you made it here safely," she took his hand, and started leading him to the luggage claim to gather his belongings.

"Still don't trust flying, even after your dragon adventure?" He laughed, remembering the letter explaining how she rode the back of a dragon, even included a clipping from the paper. She explained that she charmed it, so anyone else wouldn't see it moving, like it did in her world. "How do you plan to return home with me?"

"I have you know, I am never scared when you're around, you should know that by now daddy," She assured, as she watched him grab his bag, which she had also sent with the last letter informing him that it was charmed to fit anything he wanted inside. "Glad you're getting use of the bag, we'll take a taxi to the hotel I been staying at for the last couple of months, the funeral is in two days. I got tickets to return us home, a week afterward."

"Why are you staying in a hotel?" He asked, as his daughter haled a taxi.

"Because they didn't want a freak as a daughter, and thought I would be an embarrassment to there friends. When I turned fourteen at school they sent me a letter, saying that I shouldn't bother coming home, because they had tried long enough to accept my abilities." She smiled as her dad held the door open for her, before sliding into the back seat.

"Why didn't you tell me this sooner, I would had come for you, and than help you find a magical school in the states. Where were you staying this whole time?" Her father asked, taking a hold of her hand, as they left the parking lot.

"I was able to wire your checks to my account in Gringott's, since I am the first descendant in my line for magic," She explained, smiling at her father, "so I had either stayed at the Burrow, or in a hotel on my breaks."

"I wish you didn't have to be on your own at such a young age," He wrapped his arms around his daughter, as he started stroking her hair, "I have missed you, Peanut."

"I missed you to, daddy," She smiled, resting her head against his shoulder.

A Couple Day's Later

David, sat beside his crying daughter, as they watched her parents being lowered into the ground. He wrapped an arm around her, as they got to there feet, to toss a handful of soil when the coffins were lowered. He held his now shaking girl tightly against his chest, as he fought against his own tears, at his daughters loss, "I'm so sorry, Peanut."

A choked laugh erupted, as she turned watery eyes to look up to him, "Peanut?"

He kissed her temple, before taking her hand, and leading her to the waiting limo, "You use to like when I called you, Peanut."

"I do, it's just after everything that I been through, and now with there deaths," She fought against the tears, as she started playing with the hem of her skirt, "It's just feels normal," she smiled at the confused look on her dads face, as she squeezed his hand, "Normal is a good thing."

"Let's get back to the house reception, Peanut," He opened the door to the car, and waited until she got in, before getting in after her.
