It was someone who looked about 10. She had to be her little sister. But Jon had a little brother. What could have caused that change?
"Samantha! You're gonna be late! Mom wants to hurry up!"
She quickly grabbed her phone and wallet, put them in her purse, and dashed out following her little sister. She knew who nobody was. First, I'm a girl, and now her little brother is too?
Perhaps her trip out would explain what sort of world she was in.
