Heartwarming / NUMB3RS

• 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!
• Calculated Risk: Don taking in Daniel Shay after his mother is killed to avoid having him stay at a group home.
  • Their hug at the end of the episode when Don takes Daniel to the airport, since Daniel is going to live with his grandmother.
• Everyone saying goodbye to Larry before he goes into space, and him going off with Buzz Aldrin and them toasting his lift-off.
• "Harvest":
  • The reunion of Santi and her sister, Prita, at the end.
  Santi: How did you know she would be okay?
  Amita: You gave us the information we needed. And I believe in the people who were looking for her. And... (Amita pulls up her jacket sleeve, showing the red yarn bracelet proving she did a puja for Prita's safety and the sisters' reunion)
  • When Santi learns that Amita teaches at a college, she wistfully reveals that she attended school once and loved it, but had to stop going when her family couldn't afford the tuition anymore. So Amita decides to use the prize money she received from a mathematical award to pay for Santi and Prita to return to school and complete their educations to help give them and their family opportunities for a better life once they get back to India. She then decides to use the money left-over to finance a spring break trip to India with her grandmother, as the events of the episode sparked an interest in her Indian heritage.
  • During the episode, Alan shares a story with Don about a friend of his who died from kidney failure the previous year, because he and his family couldn't find an organ match among their family and friends, and they couldn't find another donor in time. Alan also points out that this is part of the reason why a lot of people are desperate enough to turn to black-market organs despite the legal and moral wrongs behind them. This story, combined with the events of the episode, inspires Don to go to the DMV and get himself registered as an organ donor. This also inspires Charlie to become a donor, as well.
• In "Provenance", a Jewish-Holocaust survivor named Erika Hellman and her grandson Joel have been in a claims dispute over a Pissaro painting that Erika claims had belonged to her family before the Nazis had sent them to the death camps from the current owner of it. In the end, it's revealed that the Pissaro painting that had been the center of the episode is a fake, much to everybody else’s surprise. The original is found to be sitting in a police vault in Budapest, because Erika's father had commissioned an art forger to recreate the painting and gave him the original for safekeeping to keep it out of the Nazis' hands, and when the Hungarian police arrested the forger in 1946 they had assumed that the painting was one of the fakes they were taking as evidence. As such, the Hellmans are able to claim the original since no one else has a claim anymore. Once Don hands the real painting over to Erika and Joel, the joy of them to having one relic of their pre-World War II family heritage back is very visible on their faces.
  Joel: It's yours, Grandma. Always has been.
  Erika: After all these years... To think, even I was beginning to question what I remembered was true.
• The Season Finale for the fifth season. 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 Eppes together.
  • "Dreamland": Alan, Amita, and the heirloom passed to daughters. So sweet.
• 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 this 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 about a conspiracy.
• "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 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.
• Some Fridge Heartwarming in "Tabu". When David is talking with Upchurch, the kidnapping specialist, he mentions that his recent "cowboy" streak is because he "had a few things on [his] mind" — "Trust Metric" had already made it clear what those "things" were. At the end of the episode, when he chooses to take a disabling shot over a kill shot, Upchurch remarks on how he finds that action unsuited for a "cowboy", to which David tells him he's "Not a cowboy, just a field agent". In context, it seems that it's not just a rejection of Upchurch's offer, it's also a final confirmation that things with him and Colby really are back to normal.
