** Yumi suggesting the caricative party to help victims in Japan to Mr Delmas:
-->'''Yumi:''' I thought it was a good idea...\\
'''Mr. Delmas''': That is not a good idea, Mrs Ishiyama.\\
'''Mr. Delmas:''' That is a ''great'' idea!
** Ulrich actually gets sick of Yumi, argues with her ''again'' and leaves her dealing with preparing her party alone, refusing to help. Who gets him to come back ? [[spoiler:[[TheRival William]], of all people, by saying she needs him and admitting he was such a jerk lastly because he was sick of being seen as the bad guy. Then both of them come back and help Yumi.]]
** Aelita defying the BrokenPedestal trope after "feeling" Lyoko:
-->'''Aelita:''' This desert... It is a bit like my father.\\
'''Jérémie:''' What do you mean?\\
'''Aelita:''' Tall, warm... unlike the chaotic state of the Cortex.
* Jérémie and Aelita's exchange at the end of "Rendez-Vous".
* In "Codeless" [[spoiler:Jérémie's speech to convince William to not [[WeCanRuleTogether listen]] to his [[EvilTwin clone]]. After he said these words William turned on the clone with no hesitation.]]
-->'''Jérémie''': [[spoiler:Even if it is difficult sometimes, you have never let us down. Please think about this. [[ThePowerOfFriendship You're our friend. My friend]].]]
* The team calls off their attempt to kill XANA when [[spoiler:Aelita's mother]] is revealed to be alive and in Tyron's employ, even when Aelita herself wants to continue, because they know [[spoiler:how much she wants to see her and know that destroying XANA would end any chance of that]].
** Also, Aelita tell that she loves Jeremie no matter what, while he, Laura, and William are overhearing.
* Aelita and Yumi hanging out with Sissi in "False Pretenses", especially the ending. It definitely shows that they weren't kidding around when they said Sissi is their friend now at the end of the previous series.
