- Episode 2, when Data 7 was finally able to remember both his own past. Along his big sis Cybersix.
- While his fall was a tearjerker at best, Cyber-29/Data 7's memories of each other were aww moments. One special moment, was prior to his fall, he wanted to get a pretty flower for 6 that was on the edge of a cliff.
- In episode 10, Lucas has been turned into a Werewolf under the control of the Monster of the Week. Thanks to some encouragement from Cyber Six and a little Heroic Willpower, Lucas/Werewolf shacks off the evil Werewolfs influence and fights her off before she can kill Cyber Six.
- Cybersix (dressed as Adrian) gets injured falling into the river while fighting a monster, prompting Lucas to insist taking Adrian to the hospital. She furiously argues with him... until seeing the concerned faces of her students and relenting to assuage their fears.
- 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!
- Cyber Six takes the time to visit Lori as well, silently revealing her true identity as Adrian. Despite being irritated with Lori's crush, she felt it was only fair that Lori knew the truth before the end.
