McLean Wykowski is the father of Rosie Miles and was the grandfather of Toya Miles. After her mother's death, Rosie was left in the care of her father. It was not a pleasant time for Rosie as her father was extremely abusive to her and hit her many times, especially on her arms. It is later revealed by Lilly that he did more than hit Rosie as she was sited to have gonorrhea when she was 8 and again when she was 10. He admits when confronted that he was out in the drive way to apologize but left when he saw Philip Williams come to her apartment.
