An Aunt
Eventually, Betty became an aunt of the baby. The two were together as much as possible and they had a great time. They loved each other and Mikaela will grow up and still have Betty next to her. This was an amazing advantage Mikaela had.
Betty stayed in the house and took care of Mikaela. But she stopped calling her Sarah. She realized the truth. Betty would never leave Mikael and Bree and Anthony know that. They are confident in Betty and they live here as well.
