Episode Overview

Title: Crash Course Plot: Jeremy takes it upon himself to instruct Odd, Ulrich, and Yumi on navigating the Supercomputer, anticipating that he or Aelita might be incapacitated by X.A.N.A., who often targets them. During their training session, X.A.N.A. unleashes a polymorphic clone that attacks Jeremy, forcing the trio to manage the Supercomputer on their own. Meanwhile, Aelita is busy auditioning for the Subdigitals, competing against two others, and is unreachable. As the clone heads towards her, the friends utilize their newfound knowledge to save Aelita and shut down the tower. In a twist, Aelita wins the audition despite her abrupt departure.
