Bertram's mother visits to celebrate his birthday, but sadly for them, they do not get along very well, as Wanda continuously steals the spotlight, even if she has to go through extreme measures. Furious with his mother, Bertram stands up for himself, after practicing for a quite a while beforehand, and gives her "the talk" in front of Jessie and the Ross children, thus gaining more confidence to reveal his soft side for the children. Wanda apologizes for her bad behavior as they both happily embrace, making Bertram hungry in the end. Meanwhile, the science world puts the Ross brothers to the test as they're assigned a project which requires an egg. Ravi decides that they should drop the egg and capture its results. Fortunately, Luke perceives this as an opportunity to prove that he is really smart by showing off his outside-the-box thinking. Unfortunately for him, Jessie and Ravi do not accept out-of-the-box ideas and Ravi claims their science project as his own achievement, which confuses Luke.
