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's really smart by showing off his outside-the-box thinking. Unfortunately for him, Jessie & Ravi don't accept out-of-the-box ideas, and Ravi claims their science project as his own achievement, which confuses Luke. Meanwhile, Bertram's mother visits to celebrate his birthday, but sadly for them, they don't get along very well, as Wanda continuously steals the spotlight, even if she had to go through extreme measures (by shunning Emma & Zuri out of their performance). Furious with his mother, Bertram gives her "the talk" in front of Jessie & the Ross kids, while learning how to stand up for himself and his family, thus gaining more confidence to reveal his soft side (love) for the kids. Wanda apologizes for her bad behavior as they both happily embrace, making Bertram hungry in the end.
