In order to pass a history test, Alex switches brains with Harper. There is a glitch, however, and the two cannot switch back. Justin is harassed by a girl, Daphne, who insists they are dating. To drive her away, Justin invites to Daphne to Russo Family Game Night, an infamous event that usually "ends in crime scene tape" due to the Russos' loud fighting. Meanwhile, Alex and Harper are still having trouble with the body switching spell - Alex winds up with two brains in her head, while a brainless Harper is tied up in Alex's bedroom. Needless to say, the game night ends in disaster, much to Justin's delight.
