"Red and Gold! Red and Gold! Red and Gold!" Two first years were prancing around the Gryffindor common room on the first day at Hogwarts, right after the sorting ceremony and the feast. The two ginger haired twins were celebrating the honour of being a Gryffindor by keeping up the rest of the house with yelling and loud laughing.
Eventually Professor McGonagall had stormed up to the common room at about one in the morning, half asleep, and yelling something about 'waking the whole school' and 'purple canaries'. After her speech, the two twins looked at each other and shrugged, and, still grinning, made they're way up to they're dorms.
By the next week, Fred and George Weasley had become so infamous amongst the teachers that they had earned themselves six detentions, and had gotten four owls to their parents, which resulted in two twin howlers.
The twins had only begun however, and they're only digression was being more sneaky, resulting in far less detentions and more time for them to plan they're latest pranks. Which was not good.
One day, sometime mid October, Fred and George were walking down the halls conversing about they're plans to jinx the quidditch supply cupboard to spit bludgers at whoever tries to open it, when suddenly Fred dropped their experimental 'Metamorphajuice' that lets you change one feature of your face, including 'pig-snout', 'fish lips' and 'elephant ears'. While stooping to clean it up, a student walked by with mousy brown hair and slipped in the lime-green puddle of potion. The student fell hard onto the stone floor while Fred and George looked shocked.
"I'm all right…" The girl muttered from the ground.
"Oh!" Fred's brain had begun to work again and he struggled to help the girl to her feet. "Thanks." She said brightly, "I'm dead clumsy, never can go a day without knockin' something over."
The twins listened to her ramble about all the things she has spilled, dropped or tripped on just that day, when suddenly George's eyes grew wide with concern.
"Hey! Y-Your hair!" The girl stopped talking long enough to hear him, and she seemed strangely unfazed. "Oh! Is it changing colours again? Can't ever get it to stay." She checked herself in a nearby window and played with her now-green hair. "I wish it would at least be a pretty colour, like pink…"
She turned to face them again and held out her hand "I'm Tonks by the way, sixth year." She smiled at their lack of words as they stared open-mouthed at her reaction. Finally realizing their state, her smile faltered only for a moment until it rekindled itself, "Oh, that! I'm a metamorphmagus." The twins seemed to come back to life at this statement, "Really? You mean our potion isn't expired?" Fred nudged George in the ribs, but Tonks paid no mind, she just laughed and said "So you're the ones who've been blowin' up all the toilets lately, I've heard of you, you're the Weasly twins."
They nodded their heads and she continued in a low voice, "I wonder how you do it, growing up with that…Percy. I would never have been made a Prefect, I lack the…how did my house leader put it? Oh yeah, ability to behave myself" The twins exchanged a rogue grin and introduced themselves in unison, believing this to be the start of a beautiful…something.
