But why does it occur? And when will it stop?

There's just no way Josie could be a thief, or could there be? It's a battle of truth vs rumour, as it becomes intolerable for Josie and Corrine to share the same living space.

While durst is teaching the class about chirality- mirror opposites- she smells the experiment's resulting liquid and becomes more laid back, just as Z is. Unfortunately the smell also gets to Z, who in turn becomes more strict that Durst ever was. Soon he becomes the acting principal of Blake Holsey, and is giving out detentions for every minor offence. The science club members must figure out how to reverse the effects before Z gets too out of control...
