Code Lyoko (2003)
S04E06 Maiden Voyage
Episode Overview
The gang persuades Jeremy to allow them to test the Skid, but things take a turn when the navigation system malfunctions, leaving them adrift in the digital sea. Jeremy rushes to his room for backup programs, but in his haste, he forgets it’s Fire Safety Day and encounters several teachers along the way, ultimately having to climb to the roof to access his room. Meanwhile, the Skid encounters another version of Lyoko and is attacked by two eel-like creatures. After fixing the navigation system, Jeremy successfully brings his friends back home and deduces that this replica of Lyoko is formed from the part of the Keys to Lyoko that X.A.N.A. stole from Aelita's mind at the end of the second season in "The Key." He ponders X.A.N.A.'s intentions for it.
