"But Gideon, you promised I could come!" The little second-year girl whined as she hurried after the three elder boys down the corridor, hugging her potion's book to her chest, her red curls bouncing with each step.

Andromeda Black turned into the corridor that the group was walking down, the Prefect badge she had received that year shining on her school robes, and got a clear view of the scene before her. She recognized the participants from one of her mother's long rants on 'relatives that the family does not socialize with'. Before her were her distant cousins Gideon and Fabian Prewett, their blonde hair and stout, muscular build were in contrast to the tall, lean red-headed boy standing next to them. Andromeda recognized him as that "blood-traitor" Arthur Weasley, now in his final year of schooling along with Gideon. Fabian still had another year left, and their little sister, Molly, five. All of them were in Gryffindor, and so Andromeda hung back; her surname and Slytherin house badge usually only served to irritate and unnerve the group before her. And after the argument that had just transpired between her and her younger sister, Bellatrix, she was keen on avoiding any more arguments tonight.

Gideon and Fabian gave their sister the same exasperated look before turning to Arthur. "Do you mind if she comes along?" Gideon asked his friend.

"Not at all," Arthur responded cheerfully. Molly beamed up at him.

"Well, then come along and keep up." Fabian ordered as he began to walk away, holding out a hand for his little sister to take. Molly clung to his arm, practically bouncing down the corridor in her delight to be included.

Overcome by intense curiosity, Andromeda followed the group, intrigued by what could make them so excited. Eventually they turned into an empty classroom and Andromeda peered around the open door. A small group of twelve or so people had gathered around an odd mechanical device, most of them recognizable to her by their lineage: it was mix of mostly Muggle-borns and Half-bloods and a few Pure-bloods, like the Prewetts and Weasley. Andromeda was disgusted with herself for a second at being able to recognize people based on those distinctions, though she did not even know their names.

Her reverie was suddenly discontinued when Ted Tonks, a Muggle-born in her year, stepped forward and tapped the machine with his wand. Music, the likes of which she had never heard before, suddenly roared into life as the large black disc began to spin beneath the arm that held it in place. Arthur Weasley, who had been carefully examining the contraption, jumped backwards in surprise.

"What'd you say this was called again, Ted?" He asked in wonderment.

"A record player."

"Record player," Arthur repeated with amusement.

Meanwhile most of the group had jumped to their feet as though commanded by the notes of the loud guitar and piano. Andromeda was stunned for a moment at this spontaneous outburst of dance as she watched the girls' full skirts fly scandalously high as their partners spun them around. But in the next moment, it occurred to Andromeda that this was not spontaneous at all. Noticing that all the desks in the room had been pushed to the edges, she realized that dancing had been the plan all along. One couple, at least, was engaged in far too skillful acts of acrobatics to have come about spontaneously, and Andromeda blushed as the girl wrapped her legs around her partner as he spun her around before setting her on the ground again. Even little Molly Prewett was tapping out the foot movements as she stood by the record player, shooting furtive glances at Arthur Weasley, as though hoping he would drag himself away from the machine and ask her to dance. She was thrilled, however, when Fabian grabbed her hand and began to twirl her around. Her pale, freckled face glowed with such happiness, that it made Andromeda sincerely wish that she had had an older brother instead of two snotty, little sisters.

"What are you doing here?"

Gideon Prewett's accusing voice caused Andromeda to jump, and she resisted the urge to flee the scene that she had been spying on. Pride overcoming her embarrassment, she strolled into the room. The happy group visibly stiffened and fell silent as the record ended, one girl even gasped. However, they all relaxed a little when Andromeda was properly in the light and realized her hair was brown, not black. Apparently, they had all thought she was Bellatrix. Awareness of the fear that Bella inspired in others shamed Andromeda, and her face flushed as she continued into the room.

Her brown eyes open wide, Andromeda spoke. "I heard noise and, as a Prefect, I came to inspect."

"We're not breaking any rules, Black!" She heard someone in the back spit.

"Do you see me handing out detentions?" She retorted.

There was a mumbling of agreement and talk of continuing on, but Andromeda's lingering presence seem to dampen the mood. She thought of leaving, knew she ought to, but her feet remained firmly planted to the spot. Finally, she asked the question she had wanted to ask since the music first reached her ears. "What kind of music is it?"

It was Ted Tonks, tie undone and shirt untucked, that answered. "It's called Rock and Roll." And he smiled at her as he replaced the old record with a new one and the music started up again.

Grateful for his acceptance, Andromeda smiled back at him.

Ted held out his hand, inviting her to dance, and Andromeda took it shyly. She didn't know the steps, but Ted showed them to her, though he was not the most graceful dancer himself. Even Arthur had abandoned his examination of the record player and was now taking it in turns with Fabian to twirl a laughing Molly around the room. And Andromeda found that she felt happier in that abandoned classroom, dancing with Ted and listening to Rock and Roll, than she had in a long time.

A/N: I've always been kind of fascinated by the more minor characters of the HP saga, and so here I am exploring how I think Molly and Arthur and Andromeda and Ted might have come together. I like to think that Molly always used to have a crush on her older brother's best friend, Arthur. Tell me what you think!
