September soon flew by, Shaula splitting her time between Pandora, Sirius and his fellow Gryffindor buddies and her small amount of school friends. She had even surprisingly started getting closer to Lily and Severus. She had met Lily through Remus, who had then invited her to study with her and Severus in the library. When Shaula had been invited to spend time with the red haired girl and the Slytherin, she felt shocked. The Ravenclaw didn't expect to meet the two friends until later in her time at Hogwarts. However, after spending a couple study sessions with them, she asked if she could invite her best friend Pandora to join them.

Severus had seemed reluctant, but he had originally seemed reluctant about Shaula joining them. But Lily was happy to let the girl bring her friend, she had even felt bad that she may have been denying the two girls to study together. Shaula had merely waved off her concern though and stated that Pandora may not even come to many of the sessions as she liked to wonder around the castle alone a lot of the time.

Shaula spent a lot of time also sending letters to her younger brother back home, with the occasional one to her parents with the basic information on her school work and that she was well. They rarely responded with nothing more than a meagerly 'Good job' more or less. The responses she gets from Regulus though, always made her happy. She had even managed to get Sirius to write letters to their brother. She told him all about Hogwarts and the lessons she has, about her teachers and her friends. She had made sure first however that Regulus wouldn't tell their parents that she was with muggleborns, halfbloods and blood traitors by bribing him with her secret stash of sweets she kept in her bottom bedside drawer under her socks.

October had slowly came to a close, and before she knew it, Halloween was arriving. When Sirius and James had found out about the muggle tradition of 'Trick or Treating' and dressing up in scary costumes from Remus and Peter, Shaula knew to dread the mischief the four would come up with for the night. The black haired girl thought over whether or not to warn her friends, and decided to only warn Pandora. She didn't want her best friend to get caught unaware in a prank that she might walk in to.

On the morning of All-Hallows-Eve, it was a Sunday and many of the students and teachers of Hogwarts were still sleeping. Shaula had gone down to the Great Hall to have breakfast by herself and perhaps read a book in her common room or spend time with Lily and Severus. Pandora had said that she wanted to go searching for a Wimbledinger, she said they mostly appeared on Halloween and were afraid of people, this caused her to want to go look for them by herself. She had thought that with if it was just her, then she should have a more likely chance of finding them. Shaula let her, it was easier to let Pandora do her own thing than have her sulking. Unlike Luna, Pandora sulked very easily and it was rather irritating if Shaula had to say.

Shaula had sat down at her table, beginning to prepare her breakfast of pancakes and fruit when Lily and Severus had joined her at the table. There weren't many people up yet so no one gave them any looks for the Gryffindor and Slytherin to be at another table. Severus didn't look to pleased to be sitting at the blue table whilst Lily simply got herself a bowl of porridge and sugar and began eating. Shaula stared at the two for a few moments before shrugging and going back to her food. The three eat in silence for a few minutes before Lily begins to speak.

"Did you want to spend the day with us? We were going to explore the castle a little then go to the library for a bit. I saw a book the other day on the uses of simple and complicated charms and I wanted to have a look at it." Severus didn't look at Shaula, he clearly didn't want her to join them. Even though the pair had warmed up to each other slowly, Severus still didn't like the idea of sharing Lily with other people. Lily didn't notice this however, and looked hopefully at the pureblood girl.

"Sure. We may bump into Pandora whilst exploring, she said she was looking for Wimbledinger's or something." replied Shaula and Lily scoffed slightly.

"I really don't understand her fascination with all these fake creatures she makes up. There's no proof any of them exists so why does she bother looking for them?" The redhead complains and Severus nods in agreement with her.

"It's because there's no proof that she wants to find them. She wants to see if she can find proof of their existence. I don't think she'll search for them for long though. Her attention span whilst large, isn't really limited to creatures. She seems to be more into researching spells and leaves the creatures to Xenophilius to find." Shaula says, defending her best friend.

"Xenophilius?"

"He's a year above us who's also in Ravenclaw."

The two nod at Shaula's explanation before setting off to explore the castle for the next hour. They get lost once or twice and each time one of them asks the nearby portraits how to get back to the Great Hall. They all soon end up in the Library however and quickly go to grab the books they've been wanting to read. They find a quiet corner in the back and open their books. Yet it's not long before Lily and Shaula begin to chat about their childhood. It's something Lily mentions though that Shaula interrupts her.

"Wait, who's Tabitha?"

"My sister."

Shaula turns to look at Severus in shock, who had finally decided to join the conversation after his ten minutes of pretend-reading and actual listening in to what they had been saying.

"You have a sister?"

"Yes, she's younger then me by two years."

"That's great, she'll be in the same year as my younger brother Regulus." Shaula mentions but mentally she had already begun thinking about all the scenario's in her head of what had happened to cause Severus to have a younger sister. Shaula had most definitely not been involved with anything muggle-related so she was unsure as to how she could have effected the timeline already for a second Snape child to be born. Was she also a reincarnation? Or was she just an unexpected person that just happened to have been born?

Before Severus or Lily could say anything to this, loud screams were heard from the corridor outside the library, which were soon followed by loud laughter and the pounding of running feet which soon faded away. Shaula and Lily had immediately jumped up, Lily quickly making her way to the exit with Shaula not far behind her. Severus, not wanting to leave his childhood friend followed after the pair.

All three heard yelling outside the library doors and stepped outside, only to be met with a large crowd of people who were surrounding a couple people who were stood in the center of the crowd. The three first years used their small bodies to squash through the crowd to see the commotion and saw a bunch of fifth year Hufflepuffs to be covered in a thick pink and purple goo that stuck to their bodies. Many people were laughing and even Shaula let out a chuckle, until one of the Hufflepuffs saw her.

"YOU! YOUR BROTHER DID THIS!"

Shaula stopped laughing then and narrowed her eyes, the students that once surrounded the Hufflepuffs, now surrounded her, Lily and Severus. Severus tugged on Lily's sleeve to try and drag her back into the crowd, but she wouldn't budge. Her Gryffindor bravery was shining at this moment.

"Nice to know." Shaula cockily replied, crossing her arms as she stared at the Hufflepuff nonchalantly. He glowered at her.

"Fix it. You're a Ravenclaw and his sister, so you should know how to get rid of this goo."

She sighed mockingly.

"Have you tried an evanesco? That might help."

"Yes we've tried that." He growled at her. One of the other Hufflepuffs grabbed his arm in warning.

"Hey chill, it was just a prank."

The angry Hufflepuff growled some more before storming off. The one who had warned him off apologized for his behavior and quickly followed after the boy. The third Hufflepuff, a girl, was silently laughing and picking at the goo. It was then that the crowd began to disperse as Madame Laubre, the librarian, had come to see what the crowd was for. It left the goo covered Hufflepuff girl, Shaula, Lily and Severus to be the only students left in the corridor as Madame Laubre gave a small sigh and began to attempt vanishing the goo on the floor.

"Tell your brother and his friends I thought the prank was hilarious, and ignore Greg. He's easy to anger." The girl said and began to walk off, leaving a trail of goo behind her, much to Madame Laubre's dipleasure. Shaula took a deep breath then and turned to Lily and Severus with wide eyes.

"What the Merlin just happened?"

"I think you just successfully sassed a fifth year..." Lily trails off, still shocked by Shaula's quick attitude change. Severus nodded, his eyes wide as he stared at her.

"Well... Okay then... I should probably let Siri know to watch his back for an angry fifth year Hufflepuff." Shaula says, before rolling her head to crack her neck and shuffles on her feet. Lily hummed in response and winces at the sound of the crack whilst Severus just grunted, also wincing. So responsive. Shaula goes to turn away from the pair, going to search for her brother before stopping and looking back at Severus.

"Hey, would it be alright if we set up your sister and my brother as penpals?"

Severus looked shocked for a minute before asking, "Why?"

"So they both could have a new friend. I know Regi doesn't really have any apart from Siri and I. So having one his age should be good, especially when they go into the same year as each other when they come here." She explains. The Slytherin thinks for a moment, before agreeing on the condition that his sister is alright with it as well. She replies with a 'fair enough' and goes off to search for her elder brother.

Throughout the day, Shaula comes across even more students who become the victims to her brother and his friends pranks. She rolls her eyes at the thought of them, but smiles as well. Halloween may not be her favourite holiday, but it is definitely one she knows she will enjoy as long as her brother is around.
