Principal from Another Planet

Donald shows a new motorcycle to the Lab Rats when they get a video  message from Douglas that Krane has lost it and implanted himself with  more bionic abilities, abilities even he doesn't know about. The Lab  Rats instead believe this to be a trap, leading Donald to activate a new  security system that only he can bypass. While Leo is at Mission Creek  High School, Douglas arrives and tries to appeal to Leo by reminding him  that he knew about Douglas and Marcus before the rest of them. Douglas  then shows Leo video footage of Krane implanting himself with bionics  and asks him to call his brother to prove his honesty.

At first, Bree relishes  her new freedom and even begins bragging to a disgruntled Leo. During a  mission, Bree feels helpless as Adam and Chase are gone for hours. Chase  reveals that they barely made it out alive and because Bree is no  longer bionic, the mission took twice as long. Bree realizes she was  selfish and apologizes to Adam and Chase. She's ready to become bionic  again, but Donald sadly tells her that since Douglas built the chips, he  isn't sure if Bree will ever be bionic again. Meanwhile, Tasha is sick,  so Leo decides to use his new pill invention on her to see if her  diagnosis will reveal the problem, but when he takes some of the  software from Eddy, Eddy is stuck in Tasha's body.

While  Donald is away, Douglas creates a new chip as close to the original as  possible, and though it seems to work, it also malfunctions by causing  Bree to run uncontrollably. Donald finds Leo with Douglas at the lab,  but helps out and all three manage to keep Bree still; however, they  still can't find a solution.
