* Charlie's moment with Don while seeing the victims in "Vector". Tell me you don't want to give them both a hug.
* In "Noisy Edge", Don tells Charlie that their dad likes to play golf with Charlie (who is an abysmal player) because it's the only thing he can teach his mathematical genius of a son. At the end of the episode, Charlie has renewed enthusiasm for the game and tells his dad "What can I say? You're a good teacher." Awwwwwwww!
* Everyone saying goodbye to Larry before he goes into space, and him going off with Buzz Aldren and them toasting his lift off.
* The Season Finale for the fifth season. [[spoiler:Charlie. Proposed. To. Amita. After ''everything else'' that had happened in that episode, too... I mean, yeah, it was almost impossible to not see it coming, but... gawd...]]
** Many of the episodes, at the end, since they usually have a nice touching family moment of the Epps together.
** "Dreamland": Alan, Amita, and the heirloom passed to daughters. So sweet.
* [[spoiler: Even though Dwayne Carter was essentially a villain who betrayed his country, he proved himself a true friend to Colby, saving him at the end of "Trust Metric". This is despite the rescue meaning Dwayne's certain death and how Colby had turned him into the cops before.]]
** In the same episode before that, Charlie was supposed to list data on reasons to trust or distrust Colby and see which outweighs the other. What does it say? Nothing they don't already know in their hearts.
* "The Fifth Man" was pretty much a Crowning Episode of Heartwarming between Don and everyone else.
* A small one in "Conspiracy Theory": David and Colby have spent almost the entire episode arguing over the Kennedy assassination. Alan gets wind of this and in one of the last scenes of the episode, he shows David and Colby a model he made with some friends at the time, and then mentions that the ensuing arguments destroyed his relationships with that group. At which point, Colby and David look at each other and then cover the model back up, deciding that their friendship is more important than who's right.
* "Breaking Point" has one between Charlie and Colby, after Charlie is nearly killed. Charlie has been trying to pretend he isn't rattled (though he clearly is) and the post-traumatic stress is interfering with his ability to work on the problem. And Colby, despite the fact that his head is deep in the case, figures out what's wrong and takes the time to reach out to Charlie, and he's the one who finally gets Charlie to open up (after both Larry and Amita have failed).
-->'''Charlie:''' I want to help you. I cannot control what's going on in my head. You don't understand.\\
'''Colby:''' That's the thing, Charlie. I do understand ,because I went through this exact same thing when I first saw combat in Afghanistan. You have to talk about the attack-- every detail, every memory, every thought that went through your head when it was happening. You can't keep it all locked inside of your head. You can't just keep going around telling everybody you're fine.\\
'''Charlie:''' Well, obviously, I'm not fine.\\
'''Colby:''' That's why you got to do something about it. It doesn't matter how scared you were. Doesn't matter if you wet your pants, man. (''Gestures to the empty parking lot'') There's nobody out here who's gonna hear it.\\
'''Charlie:''' I'd just hung up the phone with Don. I saw some taillights up ahead...
** Colby's comment at the beginning of that scene is a CMOH all on its own, both for what he says about his team and for his clear concern for someone he's never even met, but clearly identifies with.
--->'''Colby:''' When I was being held on that freighter and they had me handcuffed and Lancer was sticking me with needles, there's one thing that kept me going, and that was knowing that my team was coming for me. No matter how screwed up things had gotten, that you and David and Megan and Don were working hard and you were going to come through that door. The thing is, Bonnie Parks, she doesn't have a team. She's got nobody. And she's locked up, handcuffed, in the dark, I don't know what. But what I do know is that I want to be the one who comes through that door for her.
