Jessie believes that Connie Thompson, a math tutor she finds for Luke, will be the perfect influence, not realizing that Connie is obsessed with Luke. Connie asks Luke to a Harry Potter dance and Jessie forces him to accept. Jessie soon realizes that Connie really is a creepy stalker. Meanwhile, Ravi is convinced that he can predict the future with his Mystical iBall application on his tablet. Zuri does not believe him at first, but after asking a question that gave her an unpredictable answer (Mr. Kipling destroying her pet pony stuffed animal), Zuri finally agrees with Ravi's Mystical iBall application. Once these younger Ross siblings hear of terrible predictions about Bertram's fate from the Mystical iBall, they try and convince Bertram to stay alert.
