* When Data 7 was finally able to remember both his own past, and his friend Cyber 6.
* When after Lucas has been turned into a Werewolf under the control of the MonsterOfTheWeek. [[IKnowYoureInThereSomewhereFight Thanks to some encouragement from Cyber Six]] and a little HeroicWillpower, Lucas/Werewolf shacks off the evil Werewolfs influence and fights her off before she can kill Cyber Six.
* In the final episode, Cyber Six is about to go off to fight the enemy, fully expecting to die in the battle. Before leaving, she stops by Lucas's place to thank him for everything. He sees how anxious she is about something and moves closer to her, at which point she finally confesses to not being human (something which she's spent the entire series worrying about). He doesn't care at all, and they finally kiss!
