Double Trouble (S03E12)

As Xana's assaults intensify, the team considers bringing on a new member to lighten their load. William remains the top choice, but Yumi's mistrust of him lingers. While Jeremie devises a method to access Sector 5 directly, Xana creates a clone of him to take his place. Meanwhile, Yumi's frequent absences from class put her on the brink of expulsion if she skips again. Odd and Yumi are distracted by Jeremie's clone, hindering their efforts to save Aelita from the Scyphozoa. The creature takes over Aelita, forcing her to input Code:Xana into the way tower, which devastates The Mountain Sector and blocks their route to Sector 5. Nevertheless, Jeremie successfully finishes his program to transport the group to Sector 5 directly.
