Echoes is the thirtieth and final episode of Season 4 and the ninety-fifth episode and series finale of Code Lyoko. It is later followed by Code Lyoko Evolution (which is considered as the fifth season).

Plot[]

Following their final mission, the former Lyoko Warriors are in the cafeteria at breakfast. Odd, Ulrich, Aelita, and Jeremie are all in a somber mood as they eat because while they have finally defeated XANA for good, Franz Hopper's sacrifice to make it so leaves them with little reason to celebrate. Sissi arrives at their table to insult them and secretly places a "mini GPS" chip on Ulrich's jacket before walking away. Yumi then arrives at the table, in a noticeably cheerier mood compared to the others, and reveals that today is the day the group will shut down the Supercomputer, ending their secret careers as the Lyoko Warriors. As the group enters the manhole in the park, Sissi tracks Ulrich from her dorm room.

At the Factory, the group arrives at the Supercomputer Room, where Yumi gives a short speech about starting a new life without Lyoko. Yumi's speech is then followed by a montage commemorating her many battles in the virtual world. However, as Jeremie moves to shut the Supercomputer down, another montage is shown, summarizing the events of the series in chronological order. Jeremie then hesitates, and suddenly calls for a vote to decide whether or not to shut down the Supercomputer. Yumi is the only one to vote "yes", much to her frustration, and so the group returns to school.

Meanwhile, in her dorm, Sissi learns that the group has gone to the Factory, and plans to go there herself. Later that day, Jeremie confronts Yumi in the courtyard and reveals why he does not want to shut down the Supercomputer: his friendships with the other Lyoko Warriors are directly linked to Lyoko, and he feels that once the Supercomputer is turned off, their friendship as a group will end as well. However, after another montage celebrating the strong bond the group has grown to have, Yumi assures Jeremie that their friendship is "too strong to shut down".

In gym class, Sissi is absent, and it is revealed that she has skipped class to investigate the Factory. While Jim gives a lesson on rhythmic gymnastics, Ulrich asks Odd why he voted against shutting down the Supercomputer, and Odd admits that he will miss the thrill of fighting on Lyoko. After a montage of Odd's many battles, Jim injures himself attempting to demonstrate a gymnastic routine. When Odd and Ulrich laugh at him, they are both sent to the principal's office.

As Sissi searches the Factory, she eventually finds her way into the lab. After turning on the interface, she discovers a video diary made by Jeremie that documents all of X.A.N.A.'s attacks, and begins watching. On campus, on their way to the principal's office, Ulrich and Odd continue their conversation, and Odd asks Ulrich why he voted "no" as well. After a montage of Ulrich's various battles, Ulrich reveals that he enjoyed the satisfaction of "being a hero" that Lyoko provided for him.

Meanwhile, after class lets out, William asks Yumi about the Supercomputer, and she tells him that, unlike her, the others are sentimental about Lyoko and are still emotionally unprepared for life without it. He then uses their shared opinion of shutting down the Supercomputer as a way of making a flirtatious advance on her, which she quickly turns down in a friendly manner and walks away.

In the Lab, Sissi continues watching Jeremie's diary and has a hard time processing what she learns. As Jeremie and Aelita wait for Odd and Ulrich to be let out of the principle's office, Aelita admits that she voted "no" because she feels that the Supercomputer is keeping her father's memory alive. After a montage reliving Aelita's battles on Lyoko, as well as her first trip to the virtual world with her father, Aelita realizes that it is time to finally move on with her life. As Jeremie and Aelita agree that they are looking forward to more "carefree" lives without the dangers of the virtual world, Sissi confronts them. She reveals all of the things she learned in the Lab and threatens to tell her father.

While Mr. Delmas reprimands Ulrich and Odd for disrespecting Jim, Sissi storms into his office and recounts what she knows about X.A.N.A. and Lyoko. Jeremie and Aelita arrive in the office as Mr. Delmas, believing she is ill, decides to take her to the infirmary. Afterward, Yumi and Ulrich meet in the courtyard, where he informs her that Jeremie is performing a return in time to erase Sissi's memory. The two then talk about the Supercomputer and, after a montage dedicated to their many romantic moments, Yumi assures Ulrich that they can still have good times together even without Lyoko. They hold hands as he asks her if she promises that and she says yes as the two smile at each other as the return to the past occurs.

The return to the past brings the group back to breakfast that morning. When Sissi arrives at the table, Ulrich stops her from planting the tracking device on him. He then offers her friendship with him and the rest of the group and the others second his offer. Sissi, initially stunned, happily accepts and leaves the table on good terms with everyone in the group, and even happily greeting Yumi, who has just arrived. Yumi then asks the other if they are now ready to shut down the Supercomputer, and they all respond positively.

In the Supercomputer Room, the Lyoko Warriors hold another vote, with results of which are unanimously "yes". Jeremie then shuts off the Supercomputer, and the group exits the Factory. In the park, Jim finds the group coming out of the manhole, and asks what they are doing, to which Odd responds that they have just "closed the book on an unforgettable, adventure-filled life of heroism and danger." This makes Jim reflect on his own teenage years, but as usual, he would rather not talk about it.

As the curtains to the series finally close, there is then a short montage of the five Lyoko Warriors bidding the audience goodbye, followed by a group shot of the Warriors in the desert sector. The series ends on that note with Ulrich triumphantly unsheathing his sabers from his back with the scene then cutting to the Supercomputer Room floor, which flashes brightly in the doorway seems.

Trivia[]

  • The original French name for this episode is Souvenirs, which translates to Memories in English.
  • According to Sophie Decroisette, producers required that one of the episodes of Season 4 primarily use recycled animation.[1] The writers decided to save this for the final episode and incorporate it into the plot, saying: "this is an episode where [the group] remember[s], really. We decided to do this thoroughly: they remember and they realize that it's over." She noted reactions from higher-ups were mixed, and they had to fight for the episode, explaining: "it was a contemplative episode where almost nothing happened. It was also quite nostalgic and rather self-centered, with a somewhat deep subject".
    • In an interview conducted while they were planning the final episodes, Decroisette said she would like for Ulrich and Yumi to kiss in one of them.[2] This ultimately didn't happen for unknown reasons, though she said earlier in the same interview that the producers had previously blocked kisses due to the American audience disliking the series' romance elements.
  • This episode is considered an epilogue to the original four seasons of the Code Lyoko franchise, which would eventually be followed by Code Lyoko Evolution (which is considered as the fifth season of the franchise).
  • This is the only episode in the series in which no one is virtualized onto Lyoko, nor there is any encounter with X.A.N.A.'s forces, as the rogue multi-agent system was finally "destroyed."
  • This is the only episode in the original series to not feature any cutscenes whatsoever.
  • Jeremy's diary that was in this episode was also used in the IFSCL game.
  • This was the last episode to feature the series in 4:3 as Code Lyoko Evolution was featured in 16:9.
  • The title card for this episode features an inactive Tower with a blue halo, even though inactive Towers have had a white halo since the events of the Season 2 finale, The Key. This may have been a production error, or perhaps done intentionally as a throwback to the earlier seasons of Code Lyoko.
  • This episode reveals Jeremie recorded video versions of his diary entries sometime during Season 4, as he is shown wearing his red shirt in all recordings.
  • In this episode, Sissi finally discovers what the Lyoko Warriors have been up to for the past two years via Jeremie's video diary, and terrifyingly recalls and/or finds out about some of X.A.N.A.'s most dangerous attacks from the following episodes:
  • At the end, Jim finally discovers one of the secret passages used to get to the Factory, without the chance to erase his memory of it. However, this does not appear to be an issue in Code Lyoko Evolution.

Errors[]

  • During one of Odd's flashback sequences, he somehow remembers the time he got slapped in the face by Claire and Magali in A Fine Mess, even though he and Yumi had switched bodies at the time. His voice is also heard instead of Yumi's.
  • While Sissi is watching and listening to Jeremie's video diary, the latter, in the recording, states that Yumi, Odd, and Ulrich were able to save Lyoko from total destruction in Final Round when they actually all failed to do so.
  • Sissi is still using the GPS tracker when she goes to the factory, even though Ulrich is not there.
