-This scene is when Harry, Ron and Hermione formally meet Remus Lupin. In my version Margret comes with him and also meets them, instantly causing a stir. This takes place just after the Dementor leaves their compartment and Harry is recovering.-
"Harry, are you alright?" Hermione asked, pale with worry.
"What happened?" He asked, still shaken, "Who screamed?"
"Screamed?" Ron asked, confused, "No one Screamed, mate. That thing came in and you went all funny."
"I heard someone scream," Harry insisted. He remembered it quite clearly.
"The creature was a Dementor," Said Professor R.J. Lupin, awake and now pulling something from his worn robes, "It is a vile creature that draws out ones worst memories and feeds on them. It is likely that the Dementor forced you to relive the most painful moment of your life."
"But I've never heard that women's voice before," Harry complained, hating how pathetic he sounded as his voice cracked.
"Not that you can remember now," Lupin said, handing him and the others each a piece of chocolate, "But if it's in your mind then it did happen. If it is strong enough to attract such attention from a Dementor then it is quite possible that your mind has suppressed it to protect you. The mind is quite powerful in that way."
Harry stared at the haggard man. He was strange, but seemed to know a lot. Maybe too much. Multiple attempts on his life made Harry a tad apprehensive of strangers. He watched wearily as Lupin stood to examine the luggage rack. He turned and smiled pityingly at Harry.
"It's not poisoned," He said, "It'll make you feel better." Harry still didn't eat it.
"Um, sir," Began Hermione, also not eating her chocolate, unlike Ron, "What are you looking for?"
"An idiot," He said simply.
There was a squeak and Lupin smiled. He turned toward the squeak and scooped something up from the rack. As he brought his hand down they all saw that a little bat was shaking in his hand.
"You are far too easy to bait, my dear," Lupin chuckled, drawing his wand.
He taped the bat and dropped it on the seat. It quickly shifted into a girl, about Harry's age. She had pale skin and soft, elegant features, her body graceful but powerful looking. Her hair was a silky, ink black with streaks of several colors and hues tied into a ponytail at the base of her skull. She was in tattered blue jeans, a dirty, battered shirt, a patched jacket and several strange necklaces and bracelets hung from her. She had several scars, though not as many as Lupin, and her enchanting violet eyes were shooting daggers at the man, who was smiling in self-satisfaction.
"Jerk," He spat, clutching herself and shaking.
Lupin just kept smiling and handed her a piece of chocolate. She turned her nose up as it, causing him to sigh.
"You may insist that nothing can harm you, my dear," He said, patiently, "But you and I both know that with Dementors that simply isn't the case."
"I'm f-fine," She spat, her American accent coming through. He cocked an eye brow and her glare intensified. "D-damn you," She conceded, swiping the chocolate from him.
"Good," He said heading for the compartment door, "I'm going to go speak with conductor. Don't start any trouble while I'm gone."
The girl stuck her tongue out at him as he left. Hermione chuckled, hollowly. The girl blushed and shoved the chocolate in her mouth. A few moments later she stopped shaking and sighed, as if relieved. Figuring it was safe, Harry ate his own chocolate. As soon as he swallowed the first bite he felt a warmness spreading through him. By the time he finished the intense coldness that had filled him after encountering the dementor was gone, and he relaxed.
The girl was pouting, seated opposite Harry. Harry wasn't sure what to make of her. She didn't look like anyone he'd meet before, so she wasn't a student. She seemed to know Mr. Lupin well enough, judging by the way they spoke to each other. But she sounded American. Harry decided right there that this girl was odd, if not very strange.
"Um," Hermione began, trying to break the awkward silence that infused the compartment, "May I ask what your name is?"
The girl gave her an unreadable look. "Now I don't know how you guys do things around here," she said, her voice melodic yet cutting, "But where I come from its proper manners to give your name before asking for someone else's."
Hermione blushed and stumbled over her words, embarrassed. "Oh...um...well..."
The girl smiled, a wonderfully honest, warm smile that seemed to make her eyes sparkle and light up the world. "I'm just yankin' yer chain," The girl chuckled, holding out her hand, "The name's Margret, but most people call me Batty for my Ani-magus form."
"I'm Hermione Granger," The bushy haired witch said, taking her hand, "Pleasure to meet you." Margret nodded, still smiling her warm smile. "This is my friend Ron Weasley," She went on, gesturing to the Red-head who had been suspiciously silent this whole time.
"Weasley, eh?" Margret said, holding out her hand to him, "I've heard about you guys."
"Oh?" asked Ron, warily. He was accustomed to being teased for his family.
"Only good things," She assured him, "Mostly war stories. You come from a long line of proud warriors ."
Ron brightened, taking her hand and smilingly proudly. He didn't get a lot of compliments, especially such meaningful ones.
"And this is-" Hermione went on, gesturing finally to Harry.
"Harry Potter," Margret interjected, an impish glint in her eyes, "I recognized you right away."
Instinctively Harry's hand went up to cover his scare. Margret chuckled at him.
"Not the scar, sugar pop," She said, winking at him, "You look just like your dad. Except for the eyes."
"My mother's," Harry said, suprised, "How do you know that? Did you know them?"
Margret cocked an eyebrow at him. "Do I look old enough to've known them?" She asked.
Harry blushed. "Oh, um, no, of course not," He stuttered, mortified. He'd heard that women tended to be sensitive about their age.
Margret burst out laughing. It was a wonderful sound, full of life and energy, but it left Harry feeling self conscious. "Damn," She chortled, calming down, "You British are easy to bait. But seriously, I did know your parents, not that I can remember them of course. I heard about them and you from my mom and Remus, the guy that just left. They were close friends with your parents and had some pictures."
"Really?" Asked Harry, intrigued.
"Yeah," Margret said, smiling at his interest, "I can tell you some of the stories they used to tell me. We'll have plenty of time now I'm starting at Hogwarts."
"You're going to become a student?" asked Ron.
"Yep," Margret said, with a nod, "Ol' Albus asked Remus to take up a teaching position. As my Godfather and guardian he couldn't leave me behind, so I'm coming too. Of course, it took some doing to get that idiot Fudge to let me in the country, but Albus is good at handling people like him."
"Why wouldn't the minister want you in the country?" Asked Ron, confused like the rest of them.
Margret let out a humorless laugh, her eyes suddenly sad. "Well," she began, "Let s just say that he and some other people consider me an 'Undesirable element' and leave it at that."
The awkward silence began to creep back into the cabin, but this time Harry cut it off. "So, you said you knew my parents," He said, returning to her earlier comment, "But how? Did they ever go to America?"
"Wasn't born in America," Margret said, shaking her head, "I was born in Godric's Hallow like you. We were neighbors . Our parents would trade off watching us when we were babies. According to my mom we spent almost all our time together till you had to go into hiding."
"Sounds like our parent's were close," Said Harry, excited.
"Close as Blood," Margret said, smiling fondly at Harry's obvious excitement.
Suddenly the lights came back on and the train lurched forward, starting to move again. Harry kept smiling at Margret, he couldn't help it. He still thought she was odd, there was no way around it, but he also liked her. She seemed friendly and fun, and she knew about his parents.
"We're on our way now," Lupin announced, coming back into the cabin, "And I've spoken with one of your teachers," He said to Margret.
"Warning them about me, eh?" She asked impishly as he resumed his seat, "I hope you didn't go into detail. I was really looking forward to introducing myself. Maybe a flood in the dorms, or a good ol' flying toilet."
"MARGRET DREAM POTTER!" Lupin bellowed, alarmed, "Don't you dare pull that stunt at Hogwarts."
"Potter?" Hermione repeated, Harry and Ron too dumbfounded to do the same.
Lupin blinked, looking from the three kids back to his god daughter, who was smirking triumphantly at him. "You little snake," He said, irritated.
"I figured you'd want to be the one to break it to him," She said, winking at him. Lupin let out a huge sigh and slumped into his seat, mumbling about troublesome children and bats.
"Potter?" Harry asked, finally finding his voice again.
Margret beamed at him. "Remember when I said our parents were as close as blood?" She asked, continuing once Harry nod, "Well, I meant it literally. My Mom and your Dad were twins."
"But, that means-" Ron began, gaping.
"Yup," She said, with a cheerful nod, "I'm your cousin, Harry."
-Sorry Remus, but that's just how Margret is. You should know that by now. Heh, teasing Remus is so much fun, I just couldn't resist. And those of you wondering why Margret is an "Undesirable element" will just have to wait and find out like Harry.-
