Jerry and his siblings, Kelbo and Megan (Jerry revealed to the kids they have an aunt), need to retake the Wizard test that, in their teen years, determined who got to keep their powers. Unfortunately, Megan still has a grudge over Jerry, and nothing, neither the possibility of gets her powers back or her nephews happines can persuade her to redo the test. When Alex, Justin and Max see how competitive the contest gets, they realize the same test could eventually tear their family apart as well. Through the entire episode each one of them gets compared to a relative. Max to Kelbo, Alex to Megan, Justin to their dad, and Harper to their Mom. In the end Justin says Alex is nothing like Megan because Alex apologized and that's something Megan never learned to do. This is the final episode of Season 2.
