"Mia Potter," she answered easily. "That's what it legally is. When Mum and Dad,
er, your grandparents legally adopted me, I became Mia Potter. I might change it
to Hermione Potter, though. Technically speaking, Mia has always been just a nickname. I
don't expect you to call me it."
Harry looked visibly relieved at the news. She knew that her "rebirth" as Mia Potter
would be difficult for a lot of people, herself included, and she aimed to make the transition
as smooth as possible.
"Really, the only people who would are probably Sirius and Remus."
"So you're okay with being a Potter?" Harry asked her. "You don't want to stay a
Granger?"
Mia frowned, thinking of her Muggle parents. "Harry, my Muggle parents died years
ago. I know, to you, it was just a few months ago that I was sobbing in the other room
because I couldn't retrieve their memories. But I've mourned them. And I was given a gift.
A second chance, a second family, and I loved them dearly. Charlus and Dorea Potter were
my parents just as much as Richard and Helen Granger. But Richard and Helen Granger
were Muggles who raised a Muggle-born witch and couldn't understand our world. Charlus
and Dorea Potter were my... my magical parents. My blood belongs to the Grangers, but
my magic, my bond, belongs with the Potters. I am a Potter and very proud to be one."
Harry nodded in acceptance and grinned. "I love you, Hermione Potter."
When they walked down into the kitchen to find Remus sitting at the small table
reading the Prophet, Mia rushed forward and hugged him from behind, wrapping her arms
around his neck.
He laughed, craning his neck to look up at her. "Good morning, love."
"Remus, is that food?" Mia asked, glancing down at a bowl that was sitting in front
of an empty chair.
He grinned. "Tea and porridge with berries, just the way you like it."
"You made it?" With suspicion and disbelief, she sat down in the chair and poked at
the food with a spoon as though she were waiting for something to crawl out of it.
Remus briefly scowled. "Had to learn sometime. Andromeda's been teaching me."
Mia nodded and took a bite of her breakfast, chewing slowly before finally letting a
pleasant smile spread across her face. "This is so good. I'm impressed." She grinned proudly
at him and took a long sip of her tea. "Oh, you beautiful man, I could kiss you!"
