I have no claim to this whatsoever! I think I speak for everyone when I say that I am sadly not J.K.R.!
"Freddie! Stop playing and come sit down, we're going to start without you!"
"Yes, Mum," the young red head said. He set down whatever new toy he was tinkering on and ran over to the sofa where his mum and twin were sitting. They climbed into her lap and bounced about until she opened the old enchanted scrapbook.
The first pages were filled with Muggle photos of Hermione's parents, who had not been found after the war. A young, bushy haired Hermione stood between her parents in many of them. Freddie and Rose were fascinated by the thought of their mother growing up as a Muggle. They often pointed out things in the photographs and asked her about them, earning a few chuckles and long explanations before she finally turned the page.
On the next two pages were photographs of the first and second Orders of the Phoenix. Freddie and Rose would immediately start pointing and naming members. They asked countless questions about being in Dumbledore's Army (the photograph being on the next page) and frequently commented on their mum's famous school years.
After several other photos of the Weasley family and of the Golden Trio came the few wedding photos she had been able to find. Freddie and Rose would wrinkle their noses and make noises while their mum remembered the secret wedding held in the backyard of the Burrow. It had been so much of a secret that no one even knew about it until well after the Final Battle of Hogwarts. The only people who had known about the wedding were the Ministry official and her husband's twin who was the best man. Everyone else had been shocked to hear the news.
It had been two weeks after the battle that she had found out she was pregnant. Pages of photographs followed of a very pregnant Hermione shooing the camera away, sitting on a loveseat reading a new book, and sitting under the massive oak tree that stood by the pond outside. With each new photo, Hermione's belly grew larger and larger.
"Look Freddie! Our first photos!" squealed Rose who was pointing excitedly at a photo of a smiling Hermione with two heavily wrapped bundles in her arms. Freddie and Rose looked through the rest of the photos quickly: Freddie and Rose's first day from St. Mungo's, Freddie and Rose taking their first steps, and quite a few photos of the young twins pulling pranks on numerous family members.
"Mum?"
"Yes, dearie?"
"Do you miss dad?"
A small, sad smile formed on Hermione's face as she thought back on the countless pranks, teasing, and flirting she had dealt with before Fred Weasley convinced her to date him. She remembered how handsome he had looked beside the Ministry official and his twin, how his red hair clashed horribly with his magenta work robes, and the time he gave her a Patented Daydream Charm for free because she praised the magic behind it.
"Yes, I miss him. But he would be proud of both of you. You both are so much like him."
A tear ran down her face and her two children hugged her, missing the father they had never met but somehow had always known.
