Precocious- advanced for ones age
Hermione knew her youngest child was smart and not just book smart like herself, but social savvy like her father as well. She also knew that Pliade (Addie to most) Black was just as headstrong and stubborn as both of her parents.
When she talked to polite acquaintances they called her daughter precocious and Hermione had to agree.
But it was still a surprise when during holiday break of her third year at Hogwarts Addie pulled her parents and Uncle Remy and Aunt Dora into the kitchen and made them sit at the table. Then she began pacing just as either of her parents was wont to do at times of stress.
Suddenly she stopped and faced them an odd fierce light in her eyes.
"How old are all of you? On second thought that doesn't matter. How many years are between you? Specifically between Uncle Remy and Aunt Dora and between Dad and Mum."
They sat back in their chairs and as if cued Remus and Sirius simultaneously ran a hand through their hair. Then Remus spoke.
"I am eleven years older than Dora."
Sirius opened his mouth to explain his complicated situation but was cut off by his daughter's delighted voice first.
"Oh thank you! That's marvelous! It means none of you can say no later based on age because you two are the same age and Mum is seven years younger than Aunt Dora."
Hermione frowned.
"Say no to what exactly?"
Surprising to all of them her normally composed and coolheaded daughter blushed before responding.
"Well I suppose I shoul give you heads up to get used to the idea…When I'm old enough I'm going to marry Teddy."
Normally they would dismiss something like this as a girl's crush but the look in Pliade Black's eyes was uncannily like that of Sirius's when he had said Peter Pettigrew was guilty and that fact had kept him sane. This look never changed when they asked her about her decision and after the third time they all believed her.
Idly Tonks wondered if she should warn her son.
