AN: Hey everyone. This is a cross over, and I don't own either supernatural or harry potter; nor do I make anything from this or any other story. Can't say much about plot yet since I'm not sure where this is going. Guess you'll just have to wait and see along with me. As you will notice, not everything is cannon or will be for either part of the cross over, sorry. The unrecognizable spells used by the witch first introduced are Latin translations. If anyone would like a spell list at the end of the chapters for those used, please let me know. Enjoy.

The Meeting

There was no way that she could have noticed the man watching her. She wore a basic, long black dress. A gold chain hung around her hips, snug enough not to fall off. Her basic black flats made little sound as she moved about the crime scene at night. Right hand held out with a soft lumos spell lighting the tip. Bending down to get a better look at some debris, gold red hair falling forward, her hand free hand reached out and picked up a small bag. As she stood she pointed the lumos light at the bag in her hand, cursing softly as she recognized it.

He had been watching the woman case the crime scene quietly, weapon drawn as he slowly approached her. His own attire consisted of boots, old jeans, black undershirt with an AC DC logo, finished off with his favorite jacket. He allowed himself a brief look at her ass as she bent down, momentarily taking his eyes off the odd lighted stick in her hand. He quirked an eyebrow as he heard her curse at the hex bag he'd seen her pick up.

She spoke softly, "Sphaera Lucis." A small ball of light erupted from her wand, floating near her hands. To finish freeing her wand hand she stuck her wand slightly between the gold chain around her waist and the fabric of her dress. A frown crossed her face as she opened the bag and peeked inside. "Whoever did this is sick and twisted. What is the fascination with the dark things in magic?" She shook her head, dropping the bag to the ground as she pulled her wand. She spoke as she pointed her wand at the bag, "Incendio!" With that said, the bag lit on fire and burned.

He watched as she set the bag on fire before tucking the piece of wood up her sleeve. As the woman began to turn around he struck fast. His arm raised, lowering quickly as the butt of his gun met her head. There was a startled sound of surprise before she began to fall towards the ground. His arm shot out, catching her. After slipping his gun to the small of his back underneath his coat he sighed. Hefting the woman up he hefted her up and over his shoulder before carrying her back to his car. A smile crossed his face as he approached his baby, a black, unaltered 1967 Chevy Impala four door. He set her down, propping her up against the door while he went to get some rope from the trunk. Moving back to the woman he secured her wrists and ankles before opened the back door and sliding her onto the backseat.

When she nearly 20 minutes later it was to being bound and carried into a motel room over a man's shoulder. A deep frown crossed over her face as she tried to glance around at her surroundings. When they passed over the line of salt she cursed softly. Just what I did not need. Perfect… how could I let myself be seen by a hunter of all people? Well, at least I am still alive for the moment. She stiffened when she heard a man speaking to the one holding her.

"I sent you to check out the crime scene Dean, not to go kidnap some woman." He shook his head, looking up at his son from where he was cleaning some weaponry. It had been a few months since Sammy left and they were still trying to work things out with just the two of them. Needless to say, despite the way it looked he did miss his youngest and he loved both his boys a great deal. "So, you want to tell me why that woman is tied up?"

Dean looked over at John Winchester before laying the woman on the bed. He hadn't realized she was awake yet as he turned to speak with his father. "She was at the house when I got there. It seemed she was doing the same thing I was but she had this weird flash light and then…" He glanced towards the bed where she pretended to still be out for the count. "She said some Latin and a ball of light hovered near her as she inspected a hex bag she'd found. Then with another word after dropping the bag to the floor with comments about fascination with dark magic she set the hex bag on fire." He shrugged some. "I knocked her out, tied her up and brought her back here to see what she might be able to tell us first. She's obviously a witch."

The way he said the word witch had her growling in her throat. She wiggled a little bit on the bed till her wand was in her hand enough. "Resolvo." The ropes fell away from her and she jumped from the bed, moving back from the two men. "Disgusting, the lot of you uneducated, uninformed idiotic hunters. You know nothing of true magic. Yes I may be a witch but not like the ones you kill without a single ounce of regret." She actually laughed, her wand sliding more firmly into her hand as two hand guns were quickly pointed at her, both men now standing. "Please, like those would do much hard to me. Like I couldn't just leave any second I wanted to."

While his son might hesitate, John did not. He recognized the way she held on to that stick as if it were a weapon. He changed the aim of his gun slightly before pulling the trigger. He watched as the bullet went straight through her shoulder and her fingers went lax around the wand, though she didn't drop it. She did stagger back a little till she hit the wall. As she stared at them in shock she slid down the wall, leaving a streak of blood in her wake.

The pain is what shook her. Her father's cutting curse could compare to this pain, but with the shoulder the man had chosen she didn't know what she could do. Her fingers had loosened her grip on her wand and she had stumbled another step before sliding down the wall. To say she was in a mild case of shock that one of them had actually fired on her was putting it lightly. She looked up at them slowly, both men still aiming their weapons at her. "Alright… alright I'll tell you what I know but…" She looked down some, biting her lip. "Can one of you at least give me some Tylenol or something and maybe help me stop the bleeding?" She saw the younger of the two look to the older and receive a nod. As the young one she knew was Dean moved to get a first aid kit she shifted a little. "There is a different kind of witch than the ones who make deals with demons like the ones you hunt. We have our own government and laws. You break one and you go to prison and trust me you don't want to know our prison guards, at least not the English ones. There's a lot you'll likely never know or understand. The important thing is that the witch you're hunting right now is one of my own who… well she wanted darker magic and sought it the way the witches you know have."

John listened to what she said, frowning some. He didn't put down his gun but he did lower it considerably. She hadn't made a move to do anything but free herself of the ropes so far. He watch Dean come back in and walk over to her.

Dean knelt down, opening the kit. He pulled out a couple gauze pads and placed them on either side of the wound before securing it in place with more gauze and a few strips of medical tape. Then he popped the lid of a Tylenol bottle and place two tablets in her left hand before walking away with the kit back to his father.

"Thank you." She popped the tablets in her mouth and then carefully raised her right arm with her left so her wand was pointing at her open mouth. She spoke clearly, "Augamenti." A small jet of water entered her mouth before she lowered both wand and arm as she swallowed the Tylenol he'd given her. "Just a little water spell, no need to shoot me." She slipped her wand back into her sleeve and the holster there before she carefully got up, moving to sit on the bed nearest her. "Pansy Parkinson is who you're looking for. I'd give some nasty comments about what kind of witches and wizards come out of Slytherin if… well if my own parents didn't come from the same house. I was placed in Gryffindor, much to my father's dislike. Anyway, Pansy decided she wanted some more power, had some people she wanted to get rid of. The methods used by demon deal witches are covered by our laws so there's not too much we can do other at first." She sighed, shaking her head. "I was sent to find her and bring her to receive the dementor's Kiss. And before you say anything, when a dementor kisses someone they suck out the soul and leave behind a living shell."

They stared at her, wondering on some level if she was merely nuts. They had never heard of the kind of witches she was describing, nor had they heard of a dementor. As they looked at each other, communicating silently they heard a loud 'crack' sound. Turning towards the woman they started, as standing on the bed beside her was a peculiar and ugly creature.

Sandy, the Snape's house elf stood by her young mistress; dressed in a tea towel. She shook her head, fretting as she removed the gauze from the girl's shoulder. "Oh, Master Snape will be most displeased when Sandy tells him of this Little Mistress. You promised you would be careful when you left." The house elf continued shaking her head, now carefully sliding the material down to expose the bullet wound. With a humph Sandy went about using her magic. First thing she did was clean the blood away before pulling out a small vial of crystal clear liquid. "Little Mistress is lucky Master Snape gave Sandy phoenix tears. Sandy will have to tell Master Snape she used a few on Little Mistress." That said she popped the cork and applied a couple drops to the back of the wound before forcing the girl to lie back so she could put a couple in the hole to completely heal the wound.

She groaned softly, more from what the house elf was saying than from the wound healing. She let out a whimper, tossing an arm over her eyes. "Bloody hell… I did not call you Sandy. Is father keeping track of me again with that stupid spell?" She shook her head and sat up slowly, looking to the elf. "You are dismissed Sandy, thank you." She watched the house elf bow before leaving with another crack. She looked over to the stunned looking hunter's and sighed. "House elf… My father likes to cast Vulnus Certiorem. It notifies the parent or a chosen guardian if something happens to the person it was cast on."

Both men took a step forward before John held a hand for Dean to stop a moment. When John got close enough to her he touched her shoulder, inspecting the healed flesh. "The, house elf?, said it gave you phoenix tears? What are phoenix tears?" He hadn't seen healing like that before and she had appeared to feel no pin from it. His eyes caught his son's as Dean moved up beside his father to look at her shoulder as well. "The creature also called you little mistress. Why is that? Who are you?"

"Sandy serves the Snape family, it's why she calls my father master, and my mother mistress. I am little mistress because she prefers it to my name. I'm Kathleen Rose Snape. As for the phoenix tears, they're from a phoenix. They can heal nearly anything but getting them can be difficult. Fawkes liked me so the bird offers a vial of tears to my father for use on me; he replenishes the vial when it runs out but that hasn't happened yet. I usually just end up with a healer, but the way things are going lately…" She shook her head, sighing. "I think I'm going to quit the Aurors and leave England."

"The Aurors?" Dean asked, curious what exactly she did for a living.

"We deal with the dark arts but not the way you're probably thinking. Usually we track down dark wizards and witches and bring them to justice. We can also act as soldiers in a sense but mostly its intelligence gathering and defeating dark wizards. I'm here to find Pansy and bring her in, duel her to death if she provokes it." She sighed deeply, shaking her head. "I really hope I don't have to do that."

Dean stared in shock for a moment, glancing at his father who was just listening intently. "So I tied up and kidnapped a cop?"

Katy laughed, nodding. "I suppose you could say that." She took a step away from them, pulling her wand and pointing it at her clothing. "Reparo." As she spoke the word her dress repaired itself. "Pellat Sanguinem." The second spell removed the blood from the fabric.

John cleared his throat, his stance straightening. She seemed to be telling the truth; and he did remember Bobby mentioning an odd type of wand carrying witch that was as good or bad as any human. "Since we're after the same witch, will you help us track her?"

She nodded, holding her wand in her hand with it lying flat in her hand. "Point Me Pansy Parkinson." The wand spun for a few seconds before choosing a path. "We follow the direction of the wand and we'll find her."

She waited for them outside as they packed up to head out. Katy rode with John since he wasn't sure how much to trust her yet; his son's protection important. Conversation was minimal at best during the ride as she tracked the witch. A stunning and binding spell trussed Pansy up nicely. It wasn't the easiest thing to keep the Winchester's from killing the witch themselves but they let her call for the authorities. Little was said as Katy wrote up a report, giving it to the American Auror that came to collect Pansy. Providing her report then would allow her some vacation time. When it was only her and the Winchesters she turned to them with a smile. "Mind if I join you guys for a while? I have some down time from work and I could really use a break."

Dean had been impressed by her, why exactly he wasn't sure. The others had unnerved his father as well as him and they didn't relax till they were all gone; save her. He gave her a cocky smirk. "I know I wouldn't mind." He glanced at his dad who hadn't said anything before looking back to her. "You want to get a drink or something?"

She listened to his words, trying not to laugh just as much as John tried not to groan at his son's words and meaning. She merely smiled and nodded. Whatever happened, she was sure it would be a memorable experience. And who knows, maybe I'll find something to do here. It would at least be different than what she did back home. Things hadn't been the same for everyone involved when Harry had vanished a few months ago, even her god brother Draco was vaguely worried about their old classmate.
