Quirks
If Scorpius was being completely honest, he would tell you that Rose Weasley was a little weird. Devastatingly beautiful, but weird. Over the years, he realized that the redhead was not one to behave like other girls in their year. He never saw her wear short skirts or swap hair and makeup charms while gossiping about the newest Witch Weekly. He never saw her giggle and twirl her hair when the head boy strolled by in the corridors. Quite the opposite. She never showed interest in wearing trendy clothing on the weekends, preferring to wear obscure muggle t-shirts (Merlin only knows what a Foo Fighter or a Led Zepplin is). Her messy curls seemed to be nothing but an annoyance to her, constantly required to be swept back with a dragon bone clip. She never wore a drop of makeup and never so much as glanced up as boys walked past her (unless it was Scorpius, much to his intense delight).
Not only did she not dress or act like the other girls, she didn't act much like the boys in their year either. She didn't know a single thing about quidditch, she wasn't interested in pranks or dragons or Exploding Snap. Rose Weasley seemed to be in a category all her own. He found himself amused and fascinated by her uniqueness.
Over time he learned just how different Rose was. It was the little things. Like the way she hiccupped when she laughed for a long time or the way she would only eat the red Bertie Botts Every Flavor Beans. There was the way she was constantly fidgeting, the way she picked at her fingernails, the way she was so gullible her cousins were able to convince her of outlandish stories about the giant squid. The way she preferred muggle photographs to wizard ones and the way she was the most endearingly awkward dancer he had ever seen. There was the way she tucked her wand behind her ear instead of just sliding it in her back pocket like everyone else and the way she refused to take anything in life too seriously.
So yeah, Rose Weasley was a little weird. But he preferred to think of it as quirky. And if he was being completely honest, that was what he liked most about her.
If Rose was being completely honest, she would tell you that Scorpius Malfoy was a little weird. Wickedly intelligent, but weird. She knew he liked to keep quiet and not draw attention to himself, but Rose was too observant for her own good. She quickly discovered all of his secrets. Like the fact that he could recite the name of every Hogwarts headmaster in order and memorized every secret passage way in the castle before he ever stepped foot in it. She chuckled when she found out he was fascinated by muggle bicycles and got mad when he couldn't master how to ride one. She noticed the way he always carried spare parchment around in case he wanted to write down one of his random ideas for a novel. He had absolutely no sense of direction and would always get lost (she was convinced he couldn't make it to the Ancient Runes classroom without her). He tucked a quill behind his ear when he was reading and would often write out certain passages from books. He was always doodling in History of Magic yet somehow knew the date of every single Goblin riot off the top of his head. He had no interest in quidditch yet could recite facts and statistics about each of the teams from memory weeks after reading the sports section of The Daily Prophet.
Maybe the weirdest thing about him, the thing that set him apart from all the other boys in their year, was that whenever the topic of girls came up, he never seemed to express interest. She would often overhear slightly crude comments about Allie Longbottom's blonde hair or Grace Trainor's long legs; but for some reason Scorpius would never join in. In fact, he'd often look her way and smile apologetically or roll his eyes and shrug.
So yeah, Scorpius Malfoy was a little weird. But she preferred to think of it as quirky. And if she was being completely honest, that was what she liked most about him.
