Life with Derek

As preparations get underway for Marti's (Ariel Waller) 8th birthday party, Casey (Ashley Leggat) is still mourning the breakup with Max (Robbie Amell) and decides she needs closure. But instead of the official breaking up ceremony she has planned, she asks Max if he wants to get back together. Max is surprised and doesn't respond.

Sally (Kate Todd) tells Derek (Michael Seater) that she's crazy about him, but all she gets back is "right back attya Sal," and that leaves her steaming. Since he's not good at expressing his feelings, she suggests that he write her a song. Derek's taste is strictly rock - he's incapable of writing a sappy song.

Derek (Michael Seater) is bugged by Sally's (Kate Todd) so‐called friendship with her ex‐boyfriend Patrick (Robert Clark), and claims that guys and girls are never just friends. Casey (Ashley Leggat) hotly denies this, and vows to prove him wrong by making friends with Noel (Adam Butcher) who, of course, has a crush on her.

With March Break coming up, Casey (Ashley Leggat) is looking forward to a spa weekend with Emily (Shadia Simmons), and Derek (Michael Seater) has been invited to Ralph's (Shane Kippel) "party to end all parties.

Casey (Ashley Leggat) finds out from Emily (Shadia Simmons) that cute new Truman (Joe Dinicol) is rating all the girls in their class, and she only scored a 6 ½ out of 10! She insists she couldn't care less about some jerk's evaluation of her appearance, but she's obviously bothered.

When Sally (Kate Todd) announces her plans to attend an out‐of‐province university in the fall, Derek (Michael Seater) is upset and breaks up with her. He insists he's fine, but Edwin (Daniel Magder) doesn't buy his calm, cool and collected act and tries to convince Casey (Ashley Leggat) to help him help Derek.

George and Nora are having a rough weekend since all the kids are all having back‐to‐school issues.

As Edwin (Daniel Magder) takes over Derek's (Michael Seater) reign as the family snoop, his mentor orders him to dig up some dirt on the squeaky clean McDonald girls. By eavesdropping on a private phone conversation, Edwin finds out that Lizzie (Jordan Todosey) likes Allen O'Fallon, and then makes her pay him to keep quiet.

It's "Take‐Your‐Kid‐to‐Work‐Day," but this year the McDonald‐Venturis are mixing things up. Casey (Ashley Leggat) will go to the law office with stepfather George (John Ralston) and Derek (Michael Seater) will go to an important meeting with stepmother Nora (Joy Tanner), a window treatment designer.

On gym activity sign‐up day, Derek (Michael Seater) makes sure Casey (Ashley Leggat) is late for school so all the popular options are booked up. Casey ends up in fencing, with Fergus (Patrick Garrow) as her instructor, and the insufferable flirt Truman (Joe Dinicol) as her partner.

On their second anniversary, Nora (Joy Tanner) tries to distract herself from George's (John Ralston) disastrous Mexican dinner by getting Casey (Ashley Leggat) and Derek (Michael Seater) to finally tell their siblings how they tried to prevent their parents' marriage. Two years and four months ago, when George proposed to Nora, she said "maybe.

While his parents are away, Ralph (Shane Kippel) is invited to stay at Derek's (Michael Seater) for the weekend. The first night, he babysits the younger kids while the rest of the family is out. The house is turned upside down but the kids have a great time!

It's like a dream come true for Casey (Ashley Leggat). The regional auditions for Dance Mania are being held at her school, and the four finalists will perform with other regional finalists on a special live television broadcast. Casey makes the cut, along with her rival, Sadia (Romina D'Ugo). But so does 'crazylegs' Derek (Michael Seater), who enters the competition as a joke.

After pulling a devious prank on Derek (Michael Seater) a year before, Teddy (Cameron Ansell) is back, hanging around, and driving everyone in the McDonald‐Venturi household crazy. Teddy knows they want to get rid of him, but before they send him home he appeals to Derek's ego as the master prankster.

Casey (Ashley Leggat) is so worried about the future that she studies like crazy for the final exams. She warns Derek (Michael Seater) that if he doesn't start studying soon, he could be in for a rude awakening - which comes when Paul (Arnold Pinnock) the guidance counsellor informs him his C average is actually a D average.

Now that they've been dating for a few weeks, Casey (Ashley Leggat) and Truman (Joe Dinicol) have officially reached boyfriend/girlfriend status. So when Truman announces he's going to a private school party in Toronto that weekend, Casey assumes she's invited. But Nora isn't sure how she feels about Truman and doesn't like Casey travelling two hours to a party.

Prom is fast approaching, and Derek (Michael Seater) and Casey (Ashley Leggat) are scrambling to find dates. Casey had planned on going with Truman (Joe Dinicol), but isn't talking to him after what happened at the party in Toronto. And though Derek had a first, second and third choice picked out, when he finally gets around to asking, each girl has already committed to go with someone else.

In the series finale of Life with Derek, Casey (Ashley Leggat) has been chosen valedictorian of her graduating class, but a case of "futuritis" has left her struggling to write her speech, which is supposed to celebrate the future. She has received a scholarship to Queens University in Kingston but is having second thoughts about moving so far away from her family.
