Scott and his wife were planning to adopt the boy but his wife died and Julie coerced Scott to marry her so she could be close to the boy. However, throughout their marriage Julie was having an affair with Doug Williams (more to that story) who was played by Bill Hayes. And during the filming of Days of Our Live at this time, actors Susan and Bill fell in love and married in 1974 in real life, still married to this day.
