I edited the ages for Clover in the last two chapters. That way, it'll make sense for Clover and Olivia to be ten years apart and when Clover turns eighteen at one point, Olivia will be eight.
Chapter 4: Andrew
When Clover was fifteen and Olivia was five, their father decided he wanted a boy in addition to the Flaversham family.
"But I can no longer give birth to any more children, dear," Bridget told him.
"You don't have to, darling," Hiram assured her, "I'll be adopting another child."
"Oh, alright," Bridget said.
…
A little boy mouse who lived in the orphanage since he was three, was named Andrew. The orphanage lady and the other orphans were good to him, but no parents seemed to want him. He didn't know the reason, but the orphanage lady continued to assure him that the right parents would adopt him. "I hope you're right," he always said with a sigh.
"I have no idea why no parent would want you," the lady told him, "Maybe they don't see how nice and smart you are."
"I'm ten now," said Andrew, "But still no one."
"Hopefully, you'll get your chance. I have full faith in you."
As she spoke this, a door knocked. "Come in," she said.
In came the toymaker. "Hello, ma'am."
"Hello, what can I help you with?" The orphanage lady offered him a chair to sit in.
"I'm looking to adopt a boy," Hiram replied.
"Well, you came to the right place," the orphanage woman said and to Andrew, she whispered, "Andrew, pack your things."
Andrew, relieved that a parent wanted him for once, did as he was told.
"He'll be back shortly." She gave Hiram paperwork to fill out for adoption to bring Andrew to the family.
When Andrew was finished packing, he saw his new father again.
"Andrew, here is your new father," the orphanage lady announced.
"Hello, son," Hiram said, "I am your new father, Hiram Flaversham and I welcome you to the family."
Andrew couldn't believe what he was hearing. All those years he was rejected and never knew why, but he was glad to hear it from a parent who was different from any other he encountered.
"Alright, I accept," Andrew said and it was settled.
…
Bridget, Clover, and Olivia waited patiently for Hiram to come home with a boy until a door opened. It was Hiram with Andrew behind him. "Alright, ladies, here is the newest Flaversham," he announced proudly.
"Hi," Andrew said shyly as he slowly showed himself.
"I'm your new mother, Bridget Flaversham," Bridget told him, "And these are your new sisters Clover and Olivia."
"Hi, Andrew," Olivia said cutely.
"Pleasure to meet you, Andrew," Clover said.
"Pleasure to meet you, too, Clover and Olivia," replied Andrew, "I just moved here and it'll take time for me to get used to living here now that I no longer live in the orphanage."
"You're welcome to play with Olivia, Andrew," Clover said.
"Thanks, and I'd be glad to," Andrew answered.
"Just don't hurt her," Clover warned, slightly overprotective of her little sister, "She's five."
"I won't," Andrew promised, "I'll defend her from those who would hurt her like I defended myself."
"That's good and you'd be an excellent help protecting her."
…
It had been hard for Andrew to get used to being in a loving family when he lived in the orphanage for years without one. Yet he was glad to have a new family because his real parents died when he was three. His new family was patient with him. Even his sisters were pleased to consider him as a brother. Andrew played with little Olivia whenever Clover was busy with her schooling in high school. During the holidays, Clover was able to spend time with her family. Now that Andrew had a good home and a family who loved him, he knew good things would come his way; it just took time to adjust. What could go wrong?
AN: I'd like to thank Gotham317 for reviewing and the relationship between Clover and Olivia was somewhat similar to Elsa and Anna from Frozen.
Andrew's based on Penny from The Rescuers and Annie from the movie, Annie.
