Life with Derek

Fifteen-year-old Derek (Michael Seater) is unhappy about his dad's remarriage, mostly because it means he now has to deal with two stepsisters, the older of whom has her heart set on taking over Derek's bedroom. Casey: Ashley Leggat. Edwin: Daniel Magder. Lizzie: Jordan Todosey.

When Casey humiliates herself by falling on top of her new classmates in the school hall, right in front of Derek's best friend Sam (Kit Weyman) on whom she has a crush, Casey gets the embarrassing nick name: Klutzilla.

When Casey and Derek's parents decide to go away for the weekend, Casey and Derek must convince their parents that they can be trusted to take care of Edwin, Lizzie and the house without a babysitter, but Derek has other plans!

Casey gets more than she bargained for when she attempts to add a feminine touch to the living room and, in the process, starts a decorating feud between her parents. Derek: Michael Seater. Edwin: Daniel Magder. Nora: Joy Tonner. George: John Ralston. Casey: Ashley Leggat.

Casey is enraged to learn that she has been labeled a “grade grubber” by her fellow classmates. To rid herself of this unflattering rep, she decides to team up on a school project with the biggest slacker she knows: Derek. Michael Seater. Marti: Ariel Waller. George: John Ralston. Nora: Joy Tonner.

Casey engages in a high-stakes game of chance against the master of cheating siblings, Derek; and George finds himself in hot water for mentioning his ex's name during a heated argument with Nora.

Offended by the video game Babe Raider, Casey decides to counter the sexist male attitude in the house by coming up with a set of feminist house rules.

A budding romance between Casey and Sam seems to have little chance of growing after Derek informs Sam of the “male code,” which prevents friends from dating their best friend's siblings. Elsewhere, Nora and George take a quiz to determine how well they know their kids.
