AN: Victoria Greengrass is my own character, just so Narcissa has a friend besides Lucius, Bellatrix, and Andromeda.
When Narcissa woke up the next morning, it was still dark in her dorm room, no thanks to the location of the Slytherin dorms. She pulled aside the curtain of her four poster bed, only to find out that she was the last first year Slytherin girl to awaken. Not that she knew any of her fellow first years anyway; Victoria Greengrass was the only other dorm mate she had had interactions with beforehand. She quickly donned her uniform, the Slytherin crest having been magically added after her sorting, before gathering her supplies for her morning classes and descending down the stairs to the common room.
She arrived in the common room, and most of the people still there were sixth and seventh year students who had the privilege of not being stuck with morning classes. She looked around to see if Dromeda or Bella was there, but her sisters weren't in sight. But there was at least one person she recognized. She quickly smoothed out her hair and robes before she approached him. "Hi."
Lucius glanced up from the book he was reading, but it wasn't one of the textbooks he was required to have as a second year student. Instead, he was reading Curses and Counter-Curses. "Hi," he answered back.
"That's one of Bella's favorite books." Narcissa nodded toward Lucius's reading material.
"Mother and Father said I could bring it with me, but it wasn't to leave the Slytherin dorm because it would probably be confiscated by Dumbledore. But since they only teach Defense Against the Dark Arts rubbish here, they've been introducing me to the Dark Arts at home."
"Mother and Father have shown me some of it as well. Bella's much more advanced than me, though. Dromeda knows some of it, but she doesn't take as much of an interest in the Dark Arts as Bella does."
Lucius stood and said, "Let me put this back in my room, and then maybe we can walk to breakfast together."
"Okay, I'll wait here."
Lucius nodded and quickly ascended the stairs before returning a few moments later. They left the Slytherin common room, and Lucius turned toward Narcissa. "I know it can be difficult to navigate the castle at first, especially with the changing staircases."
"I would have followed Bella or Dromeda, but I think they also have a morning class, and I woke up later than I should have."
"What's your first class today?" asked Lucius curiously.
"Double block of Potions with Professor Slughorn."
"Oh, he's a great professor. You'll learn a lot from him. Since he's the Head of our House, it'll help that you're in Slytherin."
"Dromeda and Bella seem to like him. Dromeda more so than Bella. Potions and Charms are her favorite subjects. She's told me that she's thought about being a Healer, but Mother and Father probably wouldn't allow it. We're all supposed to marry into respectable pure-blood families."
"Well, a family as noble as yours knows the importance of preserving the purity of the Wizarding race."
"I know," Narcissa said. "Mother and Father have discussed betrothing Bellatrix to Rodolphus Lestrange since she is closer to graduation, but I don't know if it's come to fruition. Right now, Dromeda and I are a little young to be thinking about marriage."
The pair arrived at the Great Hall, and Lucius looked toward the Slytherin table. "My mates are over there. I hope you have a successful first day."
Narcissa smiled, though Lucius's back was to her at this point, so he didn't notice. She walked toward where her sisters were sitting and began to fill her plate with some bacon, eggs, and bangers. Bella looked up from her plate and said, "Oh, Merlin, you have that look on your face again, Cissy."
"No, I don't," said Narcissa in defense.
"Bella, leave Cissy alone," said Andromeda. "But you do, Cissy."
"Excuse me if I like being treated nicely."
"There isn't anything wrong with it," said Andromeda.
"Yes, there is. It's sickening," said Bellatrix.
"Well, I think it's nice that Cissy is already making mates. Mates that Mother and Father will approve of for Cissy." Bellatrix quieted down upon Andromeda's statement, but not for long.
"Well, I get to spend the next three years spending more time with Rodolphus since he'll be my future husband."
"I'm guessing Mother and Father finalized the betrothal?" asked Narcissa.
"Unfortunately, yes," answered Bellatrix. "Be lucky Mother and Father haven't started forcing marriage onto you, Dromeda. You'll be next. Cissy won't have to worry about Mother and Father betrothing her to someone since she's already met her future husband on her own."
"He helped me on the train, and he escorted me to breakfast to help me learn my way around the castle. It's not like he proposed to me upon meeting me. He's just trying to be a gentleman," said Narcissa. "I have no plans to marry him. Besides, I'm eleven; I'm too young to be thinking about marriage anyway."
"Then stop looking like a lovesick prat every time you're around him."
"Bella, Mother and Father don't like it when you use that kind of language. It's unladylike," said Andromeda.
"Well, Mother and Father aren't here right now," said Bellatrix and chuckled a little.
"I have to get back to the dungeons. I have Potions this morning." Narcissa wiped her mouth, gathered her belongings, and stood to leave.
"Tell Professor Slughorn I said hello," said Andromeda.
Narcissa nodded. She looked at Bellatrix, who was back to being in her own world. Narcissa also couldn't help but get a glance at Lucius one last time before leaving the Great Hall.
Later that evening, after Potions, Flying lessons, and dinner, to which she had spent most of her day with Victoria, Narcissa took refuge in the common room. It was crowded with students unwinding after the first day, and Narcissa had yet to learn the names of most everyone in the room. When she spotted a familiar face, she walked over toward the fireplace and sat down next to him. "You've changed your reading material from this morning."
Lucius looked up from his Quidditch rule book and said, "I'm trying out for the Quidditch team this year. I figured I would refamiliarize myself with the rules."
"What position do you want to try out for?"
"Either Chaser or Beater. I haven't decided yet. Father was a good Beater, though."
"Well, I hope you make it. It would be exciting to watch you play."
"Narcissa Black, is this your attempt at flattery?"
"No," she answered too quickly. "Just…besides my sisters and Victoria Greengrass, I haven't made many mates here yet. I mean, Mother and Father are well-connected with many of the noble Wizarding families, but I haven't met many of their children. Like they've been to your father's Manor before, but I hadn't met you until last night." Narcissa looked at the time. "Well, it's getting late. I should be getting to bed. Have a good night, Lucius."
He nodded in acknowledgment and went back to his reading. As Narcissa climbed the stairs to the girls' dorms, she couldn't help but blush and smooth out her hair.
