Alex, Justin, and Max get their wizard report cards. To hide the fact that she did terrible, Alex attempts to destroy the report card numerous times, all of which are unsuccessful. When Jerry and Theresa become suspicious, Alex, in a panic, turns them into guinea pigs. After Headmaster Crumbs finds out that Alex lied about her parents and her report card, he suspends Alex's powers for irresponsibility. Max and Justin lose the guinea pigs, not realizing who they actually are, and are brought up to speed by Alex. After finding them and changing them back, Professor Crumbs, shocked how much trouble Alex has caused, decides to permanently strip Alex of her powers, but Justin stands up for her, explaining that cleaning up after Alex makes him a better wizard. Moved by Justin's loyalty to his younger sister, and seeing that Alex has learned her lesson, Crumbs gives Alex back her powers and departs.
