The Enfield Haunting (2015)

Episode Overview

Upon returning from another journey to The Carthage Region, Aelita confides in Jeremie about her feelings of not being human, oblivious to the fact that Sissi is secretly recording their conversation. Meanwhile, the data retrieved from Carthage overwhelms the supercomputer, initiating a series of repeated time-travel trips. Jeremie realizes that these returns to the past significantly bolster X.A.N.A.'s strength. During the third trip, the now-empowered X.A.N.A. seizes control of Sissi and targets Ulrich. The team must find a way to confront Sissi while also halting the continuous time loops.
