Heartwarming: Lab Rats
- In "Back From the Future" the Lab Rats have this when they come to accept that the mission is going to end in their deaths like Future!Leo said. Thankfully, it doesn't.
- Chase and Leo have a heartwarming moment before they defeat the Exoskeleton together in "Exoskeleton vs. Grandma."
- Bionic Showdown has this in the end.
- Mainly in the group hug after Chase's line "He may have created us, but you made us who we are. You're our father"
- Douglas and Donald's victory dance together, after they manage to fix Bree's new chip and save her life in the nick of time in "Which Father Knows Best." Although also a Crowing Momentof Funny, it sweet cause as they both know the moves, its very likely they used to do it together to celebrate there victories, back when they worked together. And we get to see them getting to do it together again for the first time in almost twenty years.
- Douglas helping Leo by giving his newly crippled arm bionics. Likely a way of saying thank you for what happened last episode.
- In Unauthorized Mission, Perry retired because she couldn't hate the new students as much as she hates the Lab Rats. This is by far the nicest thing she's ever said about them (even if the fans were greatly annoyed).
- In One of Us, S-1 and Leo finally becoming friends after what the former did to him.
