A/N: About the whole name thing with the wee scotish girl (you know her) and her name, I do apologise for it. Most chapters are written in parts over several days and I do forget which spelling I have used. So, from now on her name will be spelt liiiiiiiike this! : Merida!

As always, thank you for the reviews and follows and alerts and faves, it makes me even more excited to update this story :) Some Elsanna fluffy times be happening!

Disclaimer: Same as always :)

Professor Spence was not the smartest of people, to say it nicely. He was good at magic, and very good at DADA, but he just wasn't very good at… thinking things through. As the large bruise and slight bags under his eyes showed the room full of fifth years.

The room was full of a mixture of Slytherins, Hufflepuffs, Gryffindors and Ravenclaws, having about 45 or so students in the room with Professor Spence pacing before a wardrobe, an exhausted smile on his face.

"Okay students! I have a real treat for you all today; the previous weekend I acquired a Boggart and I thought to myself, 'My class could use this'. And here we are!"

He was like a showman in some ways, Anna thought to herself, watching as he seemed to dance across the floor, something akin to Fred Astaire in his step.

"Now, a boggart is an amortal shape-shifting non-being that takes on the form of the viewer's worst fear. When facing a boggart, it is best to have someone else along, which is why there is so many of you, to try to confuse it, since facing more than one person at once would make it indecisive as to what form it must take, usually a mixed-up amalgam of the victims' fears. Because of their shape-shifting ability, no one knows what a boggart looks like when it is alone, as it instantly changes into your worst fears when you first see it."

He stepped forwards again and got out his wand slowly showing a gentle pattern in the air, Anna's eyes glazed over involuntarily as her mind wondered, she watched the man talk animatedly, although his words were going through one ear and out of the other. She couldn't help it if she had a low attention span.

She felt a weird sensation on the side of her face, and she turned her head a little in the direction it was coming from, meeting blue with blue as she did.

She sent a small smile, which Elsa returned with one of her own. When Elsa's eyes turned back to the front of the class after Astrid had patted her shoulder lightly, Anna ran her own over the taller girl's attire for that day.

She seemed to have forgone the cardigan for the hotter day, standing with her arms crossed easily across her chest in her white polo shirt, the sleeves rolled up to her elbows. The Slytherin tie was still around her neck properly, and her skirt was back again, although it seemed a little shorter than the time before, Anna did not mind however, as it showed off her lustrous legs which ran for miles.

Anna let out a small screech when something collided to the back of her head; she rubbed it and glared at Rapunzel, who had a smug expression. She glanced at the Professor and leant sideways to Anna.

"You may wanna stop undressing her with your eyes and actually pay attention."

"What?" Flynn asked, hearing some mumbling from his girlfriend.

"Hum? Oh, nothing sweetie." She pecked his cheek and he smiled instantly, she tilted her head back to Anna and winked when the red head girl huffed and frowned to the front of the class.

"… now after me, with out wands if you will, Riddikulus!"

"Riddikulus!" the class called back.

"And again!"

"Riddikulus!"

"Very good! Now, remember that you must imagine the thing which fears you the most to be turned into something funny, laughter will hold it back enough for a stronger witch or wizard to slay the beast, or indeed for you to flee. Now, form a line if you will, and be ready, to face your fears!" he finished in a comedic haunting voice which caused some students to laugh as they lined up.

The next fifteen minutes was filled with some squeals of fear, followed by raucous laughter as their fears were shifted. Anna's particular favourite moment was when a boy's fear was his grandmother with a walking stick yelling at him for not eating all of his cabbage, he turned her into a ball of the grotesque vegetable with her hat and glasses still on it, floating in the air while singing some muggle song.

Kristoff was the first of her friends to go up, followed by Rapunzel, whose fear was a woman with long black frizzy hair in a red dress, and then Flynn who had a rabid fire monkey for some reason, which he had doused with water.

Everyone went awkwardly silent when Astrid of the Unholy Trinity went forwards, her boggart was still for a moment, and then it turned into a man with balding blonde locks and a cane in his hand, which he snapped against his hand loudly.

"Look at what you've done you stupid girl! What have I told you about interrupting me while I am in my study?! You are in big trouble-"

"Oh shut it old man, Riddikulus!" he was immediately turned into a toad with a crown on his head. Astrid glared down at him and turned away, going to back of the room and leaning against the wall with a scowl. The room was silent after that, no one quite knowing how to break the silence.

Then, Jack moved to the front of the line, as the next student had yet to move.

The boggart immediately changed, this time into a park bench, nothing else but a bench with no one on it. Then a young blonde boy stared to fade onto it, but before it could even form properly he had used the spell and turned the park bench into a pile of wood shavings. Jack didn't even spare it a glance as he turned to go over to Astrid, sitting next to her and nodding in greeting.

The line started again, and Anna was at the front. The duck with a tiara looked at her for a second, and then shifted its form, growing huge in size and sprouting fangs, its neck enlarging and its arms and legs melting into the body.

The huge snake hissed, flicking its tongue out as several more hisses came from its throat.

Well, they sounded like hisses to everyone else, but not to Anna.

"They will allllll hate you when they find out! You will be an outcast, forgotten, lossst!"

Anna froze, her worst fear presenting itself as it lunged forwards, stopping seconds before it could touch her and darting back. Her wand was useless by her side, and the snake continued to speak.

"And your parentsss… your, brotherssss, they will think you lied to them! You're a traitor!"

"…no…" she whimpered, her legs getting shaky as tears formed in her eyes. She heard someone call her, presumably one of her friends, but she could not turn her gaze away from the nine foot snake.

"I will be doing them all a favour…"

Then it lunged for her prone form, and several things happened at once.

The room temperature dropped suddenly, steam coming from the students mouths like a dementor was near. Professor Spence slipped on his way over to her, hitting his head on a desk and knocked himself out. A scream came from one of her friends, most likely Rapunzel, as well as her other friends yelling out her name.

Then a hand wrapped around her waist, tugging at her and shifting so that Anna was now facing away from this creature. She opened her eyes, which she had not known had shut, and spun around to see her savoir, not that surprised when she saw white blonde hair in an elegant braid.

Elsa stood before the snake, who eyed her up for a millisecond, shifting the next. It shrunk in size, until it was the same height as Elsa herself. It took on a humanoid shape and its skin turned a transparent blue colour. It shocked Anna when she realised that it was a sculpture made out of ice, which looked exactly the same as Elsa.

The creature brought up its left hand, which she noticed was caked in blood, as was its right arm, and it screamed so loud that all the students had to cover their ears; Elsa remained unfazed, and brought up her wand, the only evidence of her fear being the subtle shake of her arm.

She called out the spell and fired it at the monster, only it wasn't the same as everyone else's spells. In fact, it was entirely different.

"Confringo!"

The fiery red curse hit the boggart dead in the chest, and then it seemed like a small bomb had gone off inside of it. Elsa erected a shield around both herself and Anna when it happened, protecting them from the strange purple goo like substance it released when it did indeed blow up.

Elsa was breathing deeply and she slowly lowered her wand, her knuckles white as she gripped it. She glanced back to Anna.

"You okay?" she asked. Anna nodded; Elsa smiled tightly, "Good."

Then she turned heel and walked out of the classroom, the students parting like the red sea for her. Jack stood up but she shook her head, he sighed and collapsed back onto his chair with a small nod, which Elsa did not see as she was already in the corridor.

Anna quickly made her way after her, batting away reaching hands an ignoring her friends calls, all she knew was she had to find Elsa.

When she was out of the classroom and down the corridor she looked around but could not see the head of white blonde hair. She had seemingly disappeared.

"C'mon, think, think, think!" she hissed to herself, bringing up a hand to thread through her hair as her head snapped from the left to the right. Then she remembered what she had told her the other day, in the girl's loo on the second floor.

"…I normally go to the Astronomy tower…"

It was like a whisper in her mind and Anna could have slapped herself for have not remembering sooner. Without wasting another second she turned right and sprinted down the corridor, nodding a hello to Nearly Headless Nick and ducking away from Peeves and his pesky water balloons, not stopping on her run even as Filch called after her in agitation.

By the time she was at the bottom of the Astronomy Tower steps she was thoroughly out of breath, cheeks flaming red and pants leaving her gaping mouth, her hands leaning heavily on her knees. She glanced up at the stairs and groaned.

"For," gasp, "Merlin's," gasp, "sake." She huffed. "She… couldn't have been at… the Entrance Hall… instead… could she? Nooo, of course not!"

She rolled her eyes at herself with a smile in place none the less, and with a huff she grabbed onto the wooden handrail and hauled herself up the steps.

Ten minutes later, with many breaks and mental yelling at the Architect of Hogwarts, Anna finally made it to the top of the tower, and when she did, her tiredness left her.

Her chest was no longer tight from exhaustion, her face no longer flushed from overexertion, and her breath no longer coming out in pants. Because she was there, and she still managed to take her breath away, despite it already being gone.

She was leant against the wall in the arch of the open window, leaning her head against the rail which kept her from plummeting to the cobblestone ground. Her eyes were constantly moving, scanning the grounds of Hogwarts with a tiny blissful smile. Anna almost didn't want to interrupt her, but she had run all this way, so she did.

"Hey." She whispered quietly, Elsa slowly turned her head and smiled a little bigger at her, shock flashing in her eyes as though she could not quite believe that she was even there.

"Hey." She repeated back to her, and Anna knew just from her tone that she was correct in her assumption of Elsa's thoughts.

"Surprised to see me?" she teased, her smile matching the other girl's.

"Why yes you did." Elsa laughed softly and Anna smiled, nodding to the space in front of Elsa's position on the opposite side of the small arch.

"May I?" Elsa nodded and Anna made her way to the arch, sliding down it and sitting on the cool stone with a tiny grimace.

"Geeze, why's it so cold up here?" she asked rhetorically, not expecting an answer.

"Sorry." Elsa mumbled.

"Sorry for what?" Elsa froze for a second and looked sharply into Anna's eyes, seeing the small hint of question within her humour, "It's not your fault that Britain decided to be so cruel as to make summer cold." She winked and Elsa laughed again. Then the blonde looked up with a small frown.

"Why are you here?" she asked, feeling vulnerable for some reason.

"Sorry, do you want me to go?" Anna joked and Elsa shook her head.

"No, I'm just curious as to why you came after me, or how you knew I was even here. Are you stalking me Miss Menzel?"

"Of course not Miss Arendelle! I merely, Merlin forbid, listen to you when we talk!" Elsa scoffed and Anna laughed at her own joke, Elsa shook her head in amusement and retuned her eyes to the grounds, overlooking the views. Anna quietened and just watched her, not at all in a creeper way that is.

"… It's beautiful, isn't it?" Elsa suddenly announced, Anna tilted her head slightly.

"What is?"

"Hogwarts. The grounds, the forest, the lake, the rolling hills and mountains in the distance with so much to offer. So many discoverys and freedom, adventures which could be had, and its just out of reach. But it is somewhat poetic." she laughed and tilted her head back, eyes never leaving the view.

"So close doth freedom be." Anna mumbled, entranced by the way the sunlight caught Elsa's hair in such a majestic way.

"Who said that?" she asked quietly, Anna shrugged.

"I did." Elsa huffed out a laugh and brought her legs to her chest, hugging them.

"Its beautiful though, isn't it?" she repeated her question.

"Yes you are." Anna mumbled, Elsa turned her head and tiled it in an adorable fashion, Anna's face flushed when she realised what she had said, and she stuttered to cover up her mistake.

"I- I- I mean, i-it is b-bea- beautiful. T-the sky a-an-d the c-clouds a-and-! I'm s-sorry, I'll just g-go-"

"Hey, shh it's alright." Elsa put her hand on Anna's kneecap, both to calm her and make sure she did not get up and leave, "deep breaths, with me, come on."

Anna's breath was shaky and she found it hard to take air in at first, but with Elsa's calming words and her calming smile, she slowly got her breath back.

"T-thanks. I'm sorry about the s-st-tutter, I normally control it easier." Anna flushed even redder and ducked her head.

"I didn't know you stuttered."

"Y-yeah, it only really happens when I'm nervous or excited or extremely happy." Elsa smiled.

"And I make you nervous do I?" she asked with a teasing glint in her eye.

"The nerveousest."

"Nerveousest? Is that even a word?"

"Hey! I'm trying to be cool over here." Elsa grinned and leaned forwards to smack Anna's knee lightly.

"Well, I find your stutter adorable."

"Great, I go for attractive and I get adorable?" Anna teased; Elsa raised one perfectly sculpted eyebrow.

"Who said I don't find it attractive?"

Anna's face, once again, flushed red and she mumbled some incoherent words which Elsa giggled at.

"Hey, now that you've found out a deep dark secret about me shouldn't I know one about you?"

Elsa sighed, "Alright, but tell anyone and I'll feed you to a Norwegian Ridgeback."

"Deal."

"… I wear glasses."

"…"

"Don't you dare laugh."

"I'm not!"

"…"

"…"

"Anna."

Anna snickered."

"Anna!"

"No! No, no, no, no, no! Don't take it the wrong way, it's just that you're like this secretive lady from Slytherin who is insanely cool and you're nervous about me finding out about your glasses! Besides, I always though that glasses were cool."

"Really?"

"Yeah! They can make a person look both smart and sexy in one go!"

There was a slightly awkward silence after that which was filled with their joined laughter. A few minutes later after they had both calmed down, they were once again in blissful silence.

"Can I ask you a question?"

"Sure." Elsa whispered, eyes to the sky with a small smile once again on her face.

"I-i… Merlin, sorry. It's about your Bogart, well… if y-you don't mind me asking- what was-?"

"Why was yours a snake?" Elsa interrupted, Anna would have been somewhat annoyed if it weren't for the fact she saw Elsa's teeth grit together and her hands clench a little.

"E-erm, when I was little I was playing in the garden while my brothers played Quidditch and my mother did some gardening. Father was out at work so it was just us.

"Well, I was about four at the time, and I was playing with this toy duck I had. Then I heard someone talking. I thought it was the muggle radio mother had but it wasn't, I knew this when a snake made its way up my leg and around my neck. It was a grass snake, harmless. It told me that I was gifted, and I was special. Then my mother screamed and she tore it off of me. My brothers came to see what was wrong and disposed of the snake with a banishing spell. But I then found out my mother was scared because while the snake was talking in English to me, it was just hissing to my mother, and she thought it was about to bite me."

"… So you're a Parselmouth?" Elsa asked.

"Shh!" Anna hushed, glancing around nervously for any wandering ears.

"Its okay Anna, I sound proofed the room."

"Its not that, it's just- well, I guess I-"

"You don't want to admit it, do you?"

"Well its just that I was always taught that Parselmouths were dark and evil, like You-Know-Who, Salazar Slytherin, Herpo the Foul and the Gaunt family…"

"What about Harry Potter? He was a Parselmouth, and look at him now. Head Auror, married to the star player on the England Quidditch team with three children, and he defeated the Dark Lord himself. He doesn't seem dark to me."

"What are you getting at Elsa?" Anna bowed her head a little feeling sadness well up inside of her, how could Elsa understand?

"That Parselmouths being dark is a stereotype which does not apply to everyone."

"Okay then Elsa, name me one more light witch or wizard who is a Parselmouth and I'll believe you."

Anna didn't know why she was getting so upset by this, but still tears welled up in her eyes and her throat tightened. Seriously, why was she so emotional right now?

Elsa kept her gaze firmly on her and moved forwards, sliding so that she was in between Anna's knees, which she had brought up to her chest, and she gently, so soft it felt like it wasn't even there, wiped the tear away from where it had slid down her cheek, smiling softly as she cupped the redhead's cheek.

"Well, I am looking at one right now."

Anna snorted and shook her head, "I meant other people."

Elsa hummed and leant away again, staying sat between Anna's knees with one of her own dangling dangerously over the edge out of the window. She sighed and rubbed her head.

"I wasn't going to tell you this so soon."

Anna frowned, Elsa had spoke again, but her voice seemed a little dry again, just like in the loo not too long ago when she was talking to that strange sounding man.

"Elsa? Is your throat okay?" she asked, Elsa chuckled lightly and shook her head.

"Promise me you will not freak out?"

"Okay, sure."

Elsa nods then reaches into her pocket, pulling out something silver. Upon closer inspection Anna realises that it was indeed a silver snake bracelet, curved in loops to go around the forearm. Its eyes were emeralds and it looked incredibly lifelike, and beautiful.

"Elsa, what is this?"

"Just trust me, please?"

Anna nodded and Elsa slipped the bracelet on, it glowed a strange mixture of bright burning green with silver flecks in the light for a few moments and then it stopped, Elsa huffed and spoke again, only this time she sounded different.

"Shtttiyyy sessqu eff seneshhhha."

Anna's eyes widened when Parseltonuge leaked through Elsa's lips, they widened to the size of bludgers when the snake shook its head and a gold tongue flicked out from its scaly mouth. It looked up to Elsa and flicked its tongue out again.

"You ssssumoned me Missstresss?" it questioned; Elsa did not answer the snake and looked up to meet Anna's shocked eyes with her own.

"You're not the only Parseltonuge in Hogwarts Anna."
