Shift Into Turbo, Pt. 3

S5 E3: With the current Power Ranger team fully capable of defending Earth without their guidance, Zordon and Alpha 5 are headed home to the planet Eltar at last. Divatox is going to do everything she can to keep the pair from having a safe trip, by first sending Elgar and his fleet of monstrous tanks to flank the Rangers in their Turbozords to keep them from saying goodbye to their mentors, and then by having the Amphibitor monster guard a device made to close the wormhole to Eltar with the travelers inside it! But who are the mysterious pair left behind to run the Power Chamber? Also, as the elder Ranger Teens finally graduate high school, Justin finds himself entering it early!
