The children begin to grow closer to Brad, with Dylan confiding in him that he is being picked on at school and Megan asking him to take her to a father/daughter dance at her school. One night, the kids' biological father, Sara's ex-husband Dusty Mayron, calls and discovers Sara's marriage with Brad. He suddenly announces he will be visiting the next day. Sara hesitates to let her ex-husband into their home, but Brad convinces her that it is important for the kids that their father and stepfather establish a respectful relationship..
