In the series conclusion, Justin retains his magical talents and takes over as the new Headmaster of Wiz Tech, succeeding Professor Crumbs. Despite the fact that Justin has had several love relationships during the course of the program, his most significant relationship is his ongoing one with Juliet van Heusen. Justin continues to develop his own unique brand of technology at Wiz Tech, creating such products as the Wrist-Watch-Phone, which can be activated by a single touch from an incoming call, and the Eye-Tap, which allows its wearers to send messages by staring at them on their phones. In addition to running the school day to day, he also serves as a mentor to Harry Potter when he first arrives at WizTech. It is revealed in the final book that Justin has been using his power of resurrection to bring back friends and family who have died. As part of his resolution to never lose anyone else again, he uses his talent to resurrect Juliet after she is killed in a car crash. After this event, he decides to use his power only to save lives of loved ones instead of bringing them back to life. He also creates a special place at WizTech where students who have been unfairly dismissed can work for two months while their files are being sorted through. These people are given jobs assisting teachers or working on research projects at WizTech.
