She and Erin had started to pick up their older sister's aggressive behaviour. She would put up a fight if Meghann put a finger on her.
When Jo returned 2 years later her behaviour has been improved along with Meghann. She was 8 almost 9 years old during the revisit. She was 6 almost 7 years old when Jo Frost came to help her family.
She is now 18 years old in 2016.
