Just as Vaughn's intelligence seems to be increasing, Josie's intelligence seems to be dropping. Coincidence? Not at Black Hole High...

Josie is having a hard time sleeping at night, but not in class. She has gone cathemaral - she has lost her sleep routine. More worrying, however, are the hallucinations she encounters whilst sleeping...

When Corrine's venus fly trap is left uncovered and alone in the science lab, it becomes a girl. Under the name Diana, she attends several classes at Blake Holsey, and immediately has all the boys competing for her attention. However it is Marshall that she takes a special interest in, which upsets Corrine. The other girls also don't seem too impressed with this new stranger...

Lucas cancels a long-weekend fishing trip with his father so that he can stay at Blake Holsey and investigate Victor and Vaughn. While setting up a surveillance camera in Professor Z's lab, he stumbles upon a secret compartment that holds a strange device. When activated, the device turns the school into a tesseract- causing the school to begin folding in on itself...

When certain members of the school start behaving oddly, it is clear that Tyler is behind it. Could he have gained the power to camouflage himself as others?

A strange occurance in the science lab causes Marshall's phone, a laptop, and Z's camera to shrink to nano size. Intrigued by Tyler's strange behaviour since his discovery of the worm hole, the science club decide to take advantage of the nano-sized camera, and plant it on Tyler. However things become complicated when Josie accidentally swallows the camera.

After continuously losing at hearts, Lucas modifies a new pair of glasses so that he can see through the cards. However things go awry when he becomes able to see through everything. He starts running into things because he can't see they are there. Though, still mistrustful of Vaughn, he decides to investigate his suspicions before seeking help for his impending blindness.

Marshall is testing a rocket but when he launches it, it fails to come down. Instead, a large silver sphere falls from the sky. When the gang go to investigate, the sphere dissolves, leaving behind a strange device. They take it to Z, who also has no idea what it was. When Josie touches it a panel opens up, and a timer begins to count down. Now the science club has 26 minutes to figure out what it does, and what the connection is to Vaughn...

Marshall is busy working on promotions for his band, Magnet 360. He is supposed to write a 1500 word essay for the school paper for his community service, however he runs out of time and ends up filling the space with predictions, thanks to Z's inspiring lesson on horoscopes and The Bell Curve.

Durst doesn't think Z is being hard enough on his students so decides to take his science class for him to check it out. Josie, knowing Z will go easy on her, cuts class- again.

Vaughn tells Corinne that he saw her on the Pearadyne security tapes- talking to his mother. He becomes angry at her when she denies ever seeing his mother.

Josie suddenly finds herself in 1879 by way of the wormhole. Vaughn, Lucas, Corrine, and Marshall come to her rescue. All return to the present except Vaughn, who discovers he has returned to a much different yet familiar reality...

Josie is determined to find and rescue Vaughn at all costs. Josie locates Vaughn, and they return to the present. Josie believes everything is her fault because Victor stole the ball from her. And decides she must prevent the accident at Pearadyne from occurring. Only, once she does, everything may never be the same, and she faces an unexpected reality.
