It took Rosie longer than she really would have liked to get ready for her first mission.

Because of the way her magic interacted with the technology in her brain, it had taken S.H.E.I.L.D months to figure out a way to allow her to explore her magic, or bioelectrical manipulation as S.H.E.I.L.D called it. What they had learned so far by studying her and what she could do was incredible, unheard of. Instead of calling it magic, because that was most definitely not what it was, S.H.E.I.L.D called it bioelectrical manipulation. Somehow, she was able to take the electric waves, that everything in the world emitted, and manipulate them do do all sorts of things. She could vanish bullets and break tiny objects dozens of yards away. The only major problem they had found was the her abilities didn't like technology. As far as S.H.E.I.L.D could tell, her magic was what had kept her alive during the procedure that had replaced her brain. Her powers had become so exhausted during this time that it had taken years for her to recover enough to use them again. And now, the magic was actively trying to get rid of her computer brain.

S.H.E.I.L.D scientists had done their best to find away around this problem, but it became apparent that this was beyond their capabilities. And so Fury sent out the readings the had gotten on her, and what they were trying to accomplish to some mysterious inventor. The inventor had come up with a solution, which had worked extremely well. But know that Rosie was heading into the wizarding world, she needed something that was going to block a considerably greater amount of bioelectrical waves than the original one had. And so S.H.E.I.L.D sent for the mysterious inventor again, and they delivered with a massive range of blockers. The blockers had been disguised as necklaces, earrings and headbands for Rosie to wear on a daily basis, and with enough variety that no one would really question them.

After this problem had been taken care of, which really didn't take much time at all, they had to create a cover story. As far as the wizarding world was concerned, Rosie had been adopted from an orphanage by Natasha and Clint, and raised as their nice, normal daughter in a DC apartment. The only person who knew otherwise was Snape and Natasha had used some intimidation tactics to ensure he wouldn't be talking about Rosie's true background.

Rosie also underwent serious acting lessons. Harriet Potter was to be a bubbly, happy, and intelligent girl. Rosie learned how to hold normal conversations with children her own age, something she'd never had the chance to do before. It took approximately a month for Rosie's disguise to be completed.

Natasha and Clint took on the codenames Natalie and Cliff Rushman, with Rosie named respectively.

And so, with very little time to spare, Natasha, Clint and Rosie took a flight to England, and ventured into Diagon Alley.

Diagon Alley was extremely disorienting for everyone. Natasha and Clint were trying memorize street names, stores, and where everything was located, so they could recreate the layout for Fury, while simultaneously helping Rosie with her shopping.

Many people recognized Rosie as "The-Girl-Who-Lived" practically on sight, a fact the was extremely disconcerting to someone used to blending in.

Gringotts had been a rather unusual experience as well. S.H.E.I.L.D was completely prepared to fund everything that Rosie needed, only to find that Rosie's birth parents had left her an enormous amount of money.

Rosie removed what she needed from the account, and told the goblin's that both of her parents should have access to the vault whenever they needed it. The

goblin's seemed slightly surprised by her choice, but after Rosie assured them that "Cliff" and "Natalie" were nothing but trustworthy, they were happy to provide keys for each of them.

The trio then split up to cover as much of the Alley as possible in the shortest possible time.

Rosie ended up in a shop called Madame Malkin's to buy her school robes.

"Hogwarts?" The plump woman from within the shop asked, as Rosie walked into the shop.

When Rosie nodded, she gestured for her to stand on a stool next to a blond boy.

"Where are your parents?" He asked her, looking her up and down.

Rosie observed him in the same manner he had observed her, before responding. "Mom and Dad anymore looking around. This is all very new to them, and I'm afraid they're a bit disoriented."

The blonde's eyebrows shot up. "You're American. Why are you coming to Hogwarts then?"

Rosie smiled. This was her first opportunity to test her cover story, and her own acting ability.

"I was adopted. Apparently my birth parents died protecting me from an evil wizard!"

The blonde's mouth dropped open.

"You're Harriet Potter? Are you joking?"

Rosie laughed. People's reactions upon discovering her identity were incredibly ridiculous. She'd been a mere baby when she had supposedly destroyed this Dark Lord. A baby incapable of speech, let alone the complex manipulation that it would have taken to destroy a man so completely.

"No. But I usually go by Rosalie Rushman now. I was adopted when I was very small."

The blonde considered this information for a moment, before extending his hand to her.

"I'm Draco Malfoy. It's nice to meet you."

Rosie hesitated for a moment, assessing the whole situation. This boy seemed knowledgeable about the world she had very little insight into, and had the potential to become a valuable asset. And with this in mind, Rosie reached out, and shook the hand of Draco Malfoy.
