Disclaimer: I own nothing related to Harry Potter, this story is written for entertainment purposes only, I am not receiving compensation for this work, monetary or otherwise.

Author's Note: This is the newly proofread and overhauled version of Goa'uld Magic. The only reason I didn't take the story totally down and revise it was that I didn't want to lose the following that it had, however, being a better writer than I was five years ago when I began this story, I owed it to everyone to revamp it a little.

"Ron, would you stop that? You're being a prat!" Hermione yelled as she ran away from the redhead who had a camera clutched in his hands

Harry laughed as he watched the two of them running back and forth across the grass. He leaned against a tree and smiled at Ginny who was standing across the park watching her brother and his wife playing like schoolchildren. She gave him a weak smile in return. It had been almost ten years since they had a messy split, and he didn't think she had ever forgiven him for that; despite the fact that she had gone on to marry Neville, who had come a long way from being the fat, forgetful boy everyone had picked on at school.

"Friends of yours?" The woman sitting on the park bench next to him looked up from her book when she heard him laugh.

"Old school friends, actually. I'm waiting for one of them to finish taking pictures. He's fascinated with the concept of a still pictures camera."

"Really? I wonder why." Her accent was unusual and seemed to be an amalgam of vowels from different regions of England

"So do I." Harry laughed again, "mind if I have a seat?"

"Not at all," she replied and moved over to make room for him on the bench

"So what's your name?"

"Cassandra Fraiser, yours?"

"Harry Potter, pleased to meet you," he paused for a moment, "pardon my rudeness, but, are you American?"

"Yes," she replied sheepishly, dropping her attempt at an accent and blushing

"It's alright, I was just curious. You just seem to have combined different kinds of accents."

"The problem I run into is that I hear this accent all the time, so I've started thinking with an accent, and when I talk it doesn't translate from my brain to my mouth."

"That's very interesting…" Harry trailed off, then noticed the book in her hands

"So why is it that in cold, damp, rainy London you sit on a cold metal park bench to read a book instead of being at home?"

"I'm trying to build up a tolerance to the cold."

"That is quite possibly the worst excuse I've ever heard. Worse than the one George used when he…" Harry stopped himself

"Who's George and what did he do?" Cassandra asked after a moment

"My friend's brother. He tried to get out of dropping a plate." Harry didn't mention that George was using magic to drop a plate of spaghetti on Ginny's head while they were waiting for the Hogwarts' Express.

"Was it a valuable antique?"

"No, but it made a large mess."

"Broken glass has a habit of doing that."

"Doesn't it though?" Harry smiled, finding his seven years at Hogwarts had sharpened his ability to lie.

"There's something different about you." Cassandra tilted her head to one side and Harry's smile vanished

"What do you mean?" He asked light-heartedly with another smile.

"You seem different. You have a different aura around you."

She could sense auras? But then she'd have to be a witch. And everyone in the wizarding world had heard of Harry Potter, and she didn't react as though she had known his name her entire life.

"Really?" Harry tried to appear interested as his mind raced

"Yeah, it's like this little hum." Her face grew more perplexed

"I see."

"The last time I got this feeling was…" Cassandra trailed off frightened.

"Was...?"

"I almost died. I was only twelve." She said the words slowly, with an eerie calm, as though it had happened a long time ago and she had come to terms with it, but in the back of her mind she was still just a scared little girl. Cassandra omitted that an alien had planted a naquadah bomb in her chest.

"You seem scared now. Is everything okay?"

"I'm fine. I just… could I see the back of your neck?" She asked and looked up at him cautiously

"Why?"

"Just… please?"

"Okay." Harry turned around awkwardly on the bench and Cassandra pushed aside his hair. No scar. For extra measure, she ran her thumbs along the bones in his neck to make certain there was no Goa'uld parasite wrapped around his spinal column.

"Okay, just checking."

"For what?"

"It's a long story. I can't really tell you, but, I feel better now."

"Alright," Harry tried to be pleasant and lighten the mood, when he noticed that Ron, Hermione and Ginny had disappeared

"Well, it looks like my friends left without me."

"Oh, I'm sorry!" Cassandra explained, "here I was holding you up."

"It's alright, I can find my way home on my own.

"Well I think I should get heading back to my flat. It's almost dark."

"Alright, well, it was nice meeting you Cassandra."

"It was nice meeting you too, Harry."

They shook hands and a shockwave went through Cassandra before she saw images of torturing people and slaves bowing at her feet. Just as soon as the vision appeared, she snapped out of it and glanced up.

She wrenched her hand away and looked with fear into Harry's eyes.

"You're a… you're a…"

"Not here." Harry clapped a hand over her mouth, ready for her to scream that she knew he was a wizard.

"Yes, I am a wizard but that…"

"A wizard? You're kidding right?" Cassandra hissed angrily

"That's what you were going on about isn't it?"

"No!"

"Then what was your problem?"

"You!"

"What?"

"You're a harsesis!"

"A what?"
