Dasey (Derek and Casey ) on Life With Derek

A divorced man named George Venturi, who has custody of his two sons Derek and Edwin and daughter Marti, marries a divorced woman, Nora, who has two daughters, Casey and Lizzie.

Up until that point, Casey McDonald was perfectly content with her life. Growing up as the oldest child in a household in Toronto with only her mother and sister had suited her well and brought her up as a self-sufficient and independent young woman.[citation needed].

With the addition of a stepfather, two stepbrothers, a stepsister, new school, new house and overall a whole new life, Casey struggles to find her place within the new family. The series is also based on Casey and Derek's rivalry. Also a major part of the series is a mysterious room in which only the five children are seen holding various props and making various noises in various costumes. Never are the parents seen in this room and hardly ever does anyone speak.

No the main two characters Derek and Casey are exact opposites and therefore perfect for each other. Since they are STEP-SIBLINGS and not related this is NOT incest. Many people love Dasey and there is TONS of proof on the net.

What people want to know in why can't Derek and Casey be together in the show?
