Crash Course (S04E07)

For some time now, Xana has been targeting either Jeremy or Aelita in his attacks. This worries Jeremy: if ever the two of them become incapacitated, Ulrich, Yumi and Odd would never be able to use the Supercomputer on their own. While Aelita goes to the final round of auditions held by the Subdigitals, Jeremy tutors his-reluctant-friends how to run the computer. (Prime Video)
