Valentine's Day has never been celebrated in the wizarding world the way it is in the muggle. Wizards are hardly fans of bright pinks and purples, or smelly perfumes, or love ballads with happy endings. They do, however, quite enjoy the candy, and embarrassing others for showing love during the holiday.
This particular Valentine's Day, Fred and George came up to Nim at breakfast, very excited about something they had just received in the mail. The showed it to her and she gave them a bit of a suspicious look, "Is this going to make me glittery?"
"No, dear Nimmers, it's going to explode," George said with a grin.
She threw it back at him, "Why give it to me then?" she demanded, "Go throw it at the Slytherins!"
"Oi!" Fred said, "We didn't mean that it was going to explode now!"
"Yeah," George said, "It's a firework!"
"Ah" Nim said, taking a sip of her juice.
"C'mon, Nim!" Fred exclaimed.
"At least pretend to be interested!" George said.
She rolled her eyes, "Fine," she said, "What are you going to do with it?"
"Set it off, obviously," George said with an over exaggerated roll of his eyes.
"Yeah, tonight at dinner," Fred added with glee.
"Well," Nim said sarcastically, "At least you have a plan."
"What's that supposed to mean?" Fred demanded.
"It means that no matter how you execute this plan, you are going to get detention," Nim said, frustrated with them.
"So?" George asked, throwing an arm around her shoulders casually.
"Yeah, so?" Fred asked scooting closer to her and putting his arm around her waist.
"You want me to help, don't you?" she asked with a sigh.
"If it's not too much trouble," Fred grinned
"Yes, we wouldn't want to inconvenience you," George continued.
She carefully detangled herself from the twins who were sitting on either side of her and smiled a bit, "Fine, see you later,"
She got up from the table and walked away, noticing the twins high-fiving at the table. Professor Snape was in a particularly foul mood that day. However, as the day went on, Nim found that he was the only one acting out of the ordinary.
At half past seven, Nim met Fred and George outside the huge wooden doors of the Great Hall. They were grinning and staring at the Marauder's Map. She walked up to them and coughed loudly when they didn't notice.
Fred looked up, startled, "Mischief managed," he said quickly.
"What do you want me to do?" She asked, suddenly a bit afraid of what they would say.
"Well, Nim Nam," George began.
"We are most glad you asked," Fred continued. The two proceeded to explain their plan to Nim.
A few moments later, Fred and George bounded into the Great Hall and with a giant leap, Fred bounded onto the Hufflepuff table and George hopped onto the Ravenclaw table, wands ready. Fred signaled to Nim. She skipped into the Great Hall, gave a big grin to Professor Dumbledore, threw the firework into the air, and then threw herself to the ground to avoid the effects of what was to occur next.
As soon as Nim threw the firework, Fred and George cast some sparks from their wand at the firework and then jumped back down from the tables to see the glorious show. The firework exploded in vibrant pinks and purples and interesting Valentines shapes. Nim heard the people in the Great Hall laughing in delight while Snape and Professor McGonagall tried in vain to keep order. She looked up from her spot on the floor and noticed Dumbledore chuckling.
The twins walked over to Nim after the show and offered one hand each to help her off the floor. She took their hands and got up with a hop.
"That was our most spectacular stunt yet," Fred said.
"Yes," replied George, "Don't you think, Nim,"
"Indeed, boys," Nim grinned, standing between them and taking Fred's left arm and George's in her right. Together, the three walked out of the Great Hall and into their common room, followed by smoke from the fireworks.
