Ashes to Ashes Disk to Disk - S1.E12

Kilokahn decides to experiment on himself by taking over Malcolm's body in order to experience life in the real world. He then sticks Malcolm inside of a new mega-virus monster. Sam and the others notice that it really is Kilokahn inside Malcolm's body (while he tries to cover it up to the rest of the outside world), and it is up to Servo to save Malcolm.
