Genevieve quickly rose to the top of all of her classes, proving especially adept at Transfiguration, Charms, and Potions. She supposed that reading the coursework beforehand had given her an advantage, but she also had attention to detail, which came especially handy in Potions. Even Professor Snape had momentarily dropped his snide demeanor when he tested her flawless Cure for Boils, though he quickly covered it up, spitting out an "acceptable" with a gleam in his eye. Though she knew that Snape would only give a Gryffindor the bare minimum they deserved, she resolved to work extra hard, until even Snape could find no faults with her concoctions.
Meanwhile, she struggled to keep up her superior grades in Herbology and Astronomy. She had about as much a green thumb as a Confunded Death Eater, and she simply couldn't make heads or tails of the stars and their patterns. Thus, she studied these subjects as often as possible, along with hanging out with Charlie and the twins.
Despite her growing status as the smartest first year since Minerva McGonagall herself, Fred and George (she still couldn't tell them apart) seemed to at least tolerate Genevieve, though this opinion was probably aided by the fact that she, at times, aided them in prank planning. Maybe she gave into peer pressure a little too easily, but she always managed to sneak away from the scene of the crime without getting caught. As long as she was careful not to go too far or let this new hobby interfere with classes, she decided that a nice, funny bout of mischief every once in a while was okay. Besides, the blokes could be creative.
Charlie's Prefect status didn't stop him from slipping Genevieve the occasional subtle fist bump on his way to good-naturedly reprimand the twins, who weren't so quick at escaping. "Nice work," he even commented once on a particularly complicated prank involving a few unsuspecting Slytherins.
One day, however, Genevieve tripped over her bag as she fled the scene, effectively stopping her from avoiding the wrath of Filch, the school caretaker. He pounced at the opportunity to punish more students.
"My office. Now," he growled.
While he rushed to grab the paperwork for their detentions, Genevieve sat worrying about the consequences and the twins explored the office, about to open a drawer labeled "Confiscated and Highly Dangerous" when Filch returned. Ever too curious for their own good, Genevieve witnessed George(?) drop another Dung Bomb as a diversion while Fred, quick as possible, snatched an old bit of parchment from the drawer.
Oh no, she thought. We're gonna get in so much more trouble. Surprisingly, though, she'd been stuck with only the one detention, which involved cleaning trophies, something she wouldn't have minded at all if it hadn't interfered with her studying schedule. She was already thinking of ways to rearrange it so that she would suffer (gasp!) falling behind in class.
When they were free to leave, though, Genevieve confronted Fred and George. "I know what you did," she started. They suddenly appeared guilty, but stubborn.
"Oh yeah? Are you gonna snitch, Little Miss Perfect?" Fred scoffed.
"We don't even know what it does, but we won't let you get in the way of us figuring out," added George.
"Actually, I was going to insist on helping you figure it out, seeing as I've got more brains than you two put together." Genevieve smirked, "Look, you took the . . . whatever on my watch, and I'm not one to turn down a good mystery. If I'm going to get in trouble for this, I reckon I might as well know why."
The twins exchanged a glance before agreeing. George smiled. "This might be the beginning of a beautiful friendship."
