- Code Lyoko has a few of these, including Sissi's kiss in "Ultimatum" and the near-death in "Cold War", but the standout example is the final part of the Season 2 ending, "The Key". The final two episodes of the season are an emotional rollercoster for Aelita, eventually leading to the return of her memories and the realization that she is not an AI, but a human being. At the end, though, these lines define the moment:
Aelita: The fight must go on. After all, fighting XANA is my job.
Jérémie: (motions for everyone to join hands) No, Aelita. It's our job.
- The first-season episode "Frontier", in which Jérémie becomes trapped in the limbo between Lyoko and the real world. The part at the very end: For but a single, brief second, Aelita and Jérémie's fingers touch across the void, before Jérémie is yanked back to the real world. It's not just that they want to be together. They deserve it.
- And as he comes out of the scanner, Odd, Ulrich, and Yumi not only carry him to his room and lay him on the bed, they all watch over him until he wakes up. And when he does, the viewer can feel the relief around the three. They take the time to ask how he feels, and when he tells them, the cheering makes it all stronger.
- Aelita and Jérémie are pretty good for this trope generally. this troper's favorite moment comes from "Double Take". After discovering that her new costume comes with angel wings, Aelita briefly stops to comment "Jérémie, you are the wind beneath my wings" before swooping down to save Yumi. Cue Jérémie blushing.
- There's also the scene in "Zero Gravity Zone" after the Return to the Past where Ulrich looks into the audience to see his parents sitting there just like before the whole gravity-reversal mess started...then he glanced over a little bit further to see his three friends sitting on the side-lines. One almost gets the feeling that it means just as much to him that his friends are there this time that his parents are (considering what kind of a guy his father can be at times, one can easily see why.)
- Also in "Zero Gravity Zone", even though he's an emotionally abusive Jerkass, when Ulrich's father is about to be lifted into space and Ulrich is trying to save him, he actually says "Goodbye, Ulrich....I'm proud of you! Really, I am." before letting go so that Ulrich doesn't get dragged up with him. He may not be the best father in the world, but he does love his son deep down.
- The final episode, "Echoes", was full of these.
- When William is finally free of Xana's control. Ulrich and Yumi are in the scanner room when William (who's finally back to normal) emerges from the scanners. Their first reaction is to hug him.
- "Attack of the Zombies". Milly and Tamiya attempt to interview Sissi about something, but she acts mean to them as usual and walks away, prompting Milly to pout "Ooooo, I hate her!" When the XANA attack happens, Tamiya is infected and Milly is left alone, prompting Sissi to show her true colors and develop Big Sister Instinct for Milly, very fiercely protecting her from the zombies, even channeling Ellen Ripley ("Don't you touch Milly, you hear!?") After the Reset Button, we go back to the opening scene...but this time, after Milly says "I hate her!", Ulrich and Aelita tell Milly she shouldn't say that, assuring her that deep down, Sissi actually likes her.
- An earlier example is when Milly, Tamiya, Ulrich, and Sissi are trapped in the cafeteria in "Claustrophobia." As Milly is crying from her fears of not being able to get out of the cafeteria, with Tamiya comforting her, Sissi bends to their level (phone up to her ear), and tells them that "The firemen are on their way," in a gentle, whispered tone. Sissi helps her classmates the best she could in that episode. Another case of Big Sister Instinct.
- At several points in the series, particularly in season 4, moments where Hiroki isn't being an Annoying Younger Sibling with Yumi can be very touching.
- Crossed with a Crowning Moment of Awesome, in "Ghost Channel", X.A.N.A. has trapped Ulrich, Odd and Yumi in a virtual replica of the real world and has the means to erase them though they haven't figured it out yet. Just as X.A.N.A.-Jeremie has convinced the boys to go to Lyoko and almost convinced Yumi, the real Jeremie shows up. After some back and forth, Jeremie explains that he's virtualized himself. X.A.N.A. smugly claims that this proves he's the fake since, quote, "everybody knows that the real Jeremie would never virtualize himself; he'd be much too frightened"; Jeremie recoils in horror as it is true that he's terrified of virtualizing himself (rightfully so since the last time he did, he nearly got erased from existence). His friends exchange a brief glance and all 3 declare that there's no doubt in their minds that Jeremie would virtualize himself to protect them.
- Also earlier in the same episode, despite his feelings being badly hurt by an insensitive comment by Odd, after the Return to the Past, Jeremie's completely forgiven Odd and is immediately very worried to find that Odd and Ulrich are both missing.
- This moment:
Jeremie: Alita...there's something I wanted to tell you: I'd much rather enter a virtual world..to find you waiting there for me.
Aelita: *smiles* So would I.
- "Code: Earth". All of it.
- The fact that Jim becomes allies with the kids in the episode after learning everything the kids have done is awesome! Also the fact he ends up making it up for accidentally hurting Jeremie.
- The entire episode was all for Jeremie could get Aelita back to the human world. And by the end, he does.
Jeremie: Welcome to earth.
- The ending to "False Start". Despite the fact that she still has the virus inside of her, the group still insists that Aelita still come to the real world, despite the risk of XANA coming after her. They really care for her living at least once in her life not trapped in the virtual world. Considering how Season 2 shows her out of Lyoko and living among the others, it's possible she does.
- The kids telling Principle Delmas how a good person Jim so he doesn't give him scolding for his usual paranoid behavior about them. Considering how Jim became their friend after the events of "Code: Earth" and "False Start", this is pretty heartwarming.
