The Academic Olympics team trains under Capt. Corrine (who is obsessed with winning). Josie, Lucas, Marshall, and Vaughn must figure out why they are doing things they normally couldn't or shouldn't be doing.
When Corrine auditions for Magnet 360 (Marshall's band) as a singer, she looks at an antique mirror, through which she travels. Everyone there is opposite (for example, Vaughn, the athlete, is a bookworm) and everything appears as a mirror image (i.e. whenever she would normally, say, go left, now she must go right). To return, Corrine must learn to use the creative half of her brain without losing her ability to use her logical side.
Students are becoming addicted to energy bars, especially Lucas and Vaughn, who aren't willing to give them up. The others must attempt to save them when it is discovered they contain zero calories or energy, thus weakening the addicts.
Josie and Vaughn go on their first date. Josie's watch allows her to stop time which is good at first until she can't control it and only Lucus can save her. Also Josie finds out who took her missing Qui-chong ball and the return of an old friend.
After an argument, Josie's intelligence transfers to Vaughn faster every minute, to the point where Josie is on the verge of collapse and Vaughn rebuilds a cold fusion reactor for his father. Meanwhile, Josie's clone returns the floating Qi ball to Victor.
Corrine's need to schedule every moment of her life upsets Marshall, who wants to be able to spend some random free time with her. Before they can talk about it, Corrine's Venus Flytrap turns into a human being - a girl named Diana who attracts the attention of all the boys at school and leaves mysterious marks on their arms. When Diana sets her sights on Marshall, Corrine must stop her before she eats Marshall alive.
While his friends are away during a long weekend, Lucas stays behind to spy on Victor's movements. Instead, he finds a tesseract device hidden in Professor Z's office. After activating it, the school begins to fold in on itself like a mathematical tesseract. Lucas discovers what happened to Professor Middleton and learns something about Vaughn.
Tyler organizes the school's fundraiser car-wash event, but he overhears a conversation about a new "gravity sensor", develops the ability to camouflage himself, and uses this to find out what the science club is up to.
