[[folder:Season 1]]
* Any time Reese or Finch refers to the other by their first name. However it's also often an indicator that shit just got real.
* From the ending of "Judgement" - ''"Try the Eggs Benedict, Mr. Reese. I've had them many times."''
** To put this in context, Finch is obsessed with concealing personal information about himself from everyone, especially Reese. At the beginning of the episode he refused to recommend anything on the menu of that diner because if Reese knows that Finch has a favorite meal there, it means that he's eaten there multiple times and implies that he lives close enough to that diner to make it a practical place for him to have breakfast, and would give Reese a point of data to figure out where Finch lives.
** In Season 2 episode 4, the development of their relationship is further demonstrated by the fact that Harold doesn't even hesitate to recommend an entree at a restaurant where Reese is investigating their POI.
** By the time 2.08 (Til Death) rolls around, Finch is ''amused'' when Reese starts fishing for information and even plays along.
-->'''Reese:''' I didn't know you were a baseball fan, Finch. The Mets?\\
'''Finch:''' Not particularly.\\
'''Reese:''' Orioles?\\
'''Finch:''' I suppose.\\
'''Reese:''' The A's.\\
'''Finch:''' (catches on, starts smiling) Oakland is fine. And the Cubs, and the Red Sox too. Although I'm not certain my affection for any one of these teams would reveal ''where I grew up'', Mr Reese.
* In "Get Carter", it was {{lampshaded}} early on that we don't know Detective Carter's first name. Over the course of the episode she demonstrates her ability as a parent, as a cop, as an Army interrogator (via flashbacks), as the contact for a CI, and in general as a badass. At the end of the episode we see that she's not quite badass enough, but Reese saves her life and takes the time to tell her, "Whether you like me or not, [[FirstNameBasis Joss]], [[YouAreNotAlone you are not alone]]."
* The dialog between Reese and Finch at the end of "Number Crunch":
-->'''Reese''': [[ItHasBeenAnHonor I wanted to say thank you, Harold, for giving me a second chance]].
-->'''Finch''': It's not over, John. I'm close, just get to the ground floor.
-->'''Reese''': No, You stay away. Don't even risk it.
** Also doubles as a major {{tearjerker}}.
** Plus the fact that Finch is willing to risk death or imprisonment (which would inevitably lead to his death) to save Reese, despite Reese telling Finch not to come and save him.
* Finch's occasional usage of his wealth to resolve problems totally unrelated to what the Machine is predicting.
** For instance, after one week's [=POI=], an unemployed construction worker, is out of danger (but still unemployed and near bankruptcy), Finch casually mentions to Reese that he owns a construction company that needs a new foreman on a big project the company just landed.
* Near the end of "Risk", Reese takes a moment to thank his homeless friend Joan for looking after him when he was living on the street. She asks who's looking after him now, and he replies "Someone new" as we see a shot of Finch sitting in the library, listening to the conversation over the phone and he appears touched.
* In "Identity Crisis", the normally reserved Finch gets [[SlippingAMickey doped up on ecstasy]] and openly offers to answer any question Reese asks him; Reese refrains from taking advantage of the situation, despite his obvious curiosity about Harold's background.
** This troper found the release of Kyle Morrison at the end of the episode very heartwarming, as an innocent man being able to return home to his little girl...*sniff*
* In "Many Happy Returns", Finch gives Reese a key as a birthday present but there's nothing to indicate what it goes to. At the end of the episode, Reese learns that it's the key to a brand-new apartment over-looking the park where he plays chess during his free time.
** Which incidentally implies that Finch's statement earlier in the episode that he doesn't keep track of what Reese does in his free time was a blatant lie.
** Harold lying to John actually becomes [[HeartwarmingInHindsight heartwarming in hindsight]] once you understand that [[spoiler:he knew what had happened in New Rochelle and was actually trying to spare John the pain of dragging up some highly unpleasant memories.]]
** Not to mention that you could also make an argument that he may have been trying to protect John from ''himself''; while Harold may not know exactly what occurred when [[spoiler:John confronted Peter,]] he likely has a pretty good idea anyways and it could be that he was trying to protect John from having to face that side of himself again.
* Finch sees to it that the magazines he owns [[spoiler: give his fiancee Grace steady work as a freelance illustrator.]]
* After Reese tells Fusco that he can keep all the money he's making by working undercover in HR, the first thing Fusco thinks to spend it on is his son.

[[folder:Season 2]]
* After Reese has rescued Finch from Root and returned him to the library, Root calls the person who just ruined her plans to get to the Machine (for now, anyway) ... and thanks him for finding out what happened to her best friend, who had been kidnapped and murdered twenty years previously. It is currently the only humanizing moment for an otherwise amoral character.
* In "Masquerade", Finch slowly growing to like Reese's new dog is both Heartwarming and amusing.
-->'''Finch''': *throws a ball for the dog to fetch while talking to Reese*
-->'''Reese''': What was that noise, Finch?
-->'''Finch''': [[BlatantLies What noise? I didn't hear anything]].
** In fact, three episodes later, it's quite clear that Bear is ''Harold's'' dog, not John's.
* Reese's gentle understanding of Finch's PTSD after his abduction by Root, and his gentle but firm insistence that Finch get out of the library.
* The birthday scavenger hunt Harold arranges for Grace in "'Til Death".
** Harold and Grace in general, really.
* In "Shadow Box", Finch comments that Reese seems to be in a good mood; Reese confirms that he is, and says that he actually felt ''happy'' when he woke up that morning. "It must be this job." Finch appears touched and responds with a sincere, "Well, I'm glad."
** This also doubles as a {{tearjerker}} when you realize that this is very likely the first time Reese has been genuinely happy since he and Jessica spent a weekend together in Mexico ''eleven years ago''.
* Bear's delight when Reese comes home at the end of "Dead Reckoning" after being away for three episodes.
** Not to mention the genuine smile on Reese's face as he accepted Bear's welcome home dog-tackle. Not a smirk, or a lazy smile, but a genuine happy smile. This Troper's heart ''melted''.
* Pretty much the entire scene on the rooftop between Finch and Reese in "Dead Reckoning," but especially this bit of conversation:
--> Reese (a bomb vest strapped to him that will go off in a couple of minutes) trying to get Finch to get out of the danger zone: "This is my past catching up with me; it doesn't concern you."
--> Finch: "But this moment does. I'm not leaving you here, John, so can we please stop wasting time?"
* Also, right before the rooftop scene, Carter and Reese's exchange:
---> Carter: "John, you don't have to do this."
---> Reese: "You know I do. Because you'd do the exact same thing."
* From "Booked Solid", Reese introduces Mira to Fusco and tells her that she can trust him, and then he looks directly at Fusco afterwards to confirm that he meant it and that he trusts him as well. Considering that he has a tendency to disregard Fusco, that was pretty huge.
--> '''Reese''': "Mira, this is Lionel; and you can trust him."
* Finch's speech to Shaw, who is almost insanely paranoid.
--> '''Finch''': "The world looks like it did ten years ago, but underneath, it's become very strange indeed. [[SecretWar An invisible struggle has begun]]. Most of the people who knew this are already dead. All things being equal, I prefer you didn't join them."
* At the end of "All In", Finch hires the now out of danger POI to repair the watch he destroyed at the end of "One Percent". It's a two million dollar watch, so repairing it will easily earn Lou the money he needs to buy his late wife's former place of work and ensure that nobody can ever try to turn it into a parking lot again.
* "Trojan Horse": Finch and Monica's interactions. She's clearly a woman Finch could get to know better under the right circumstances.
** Also, Shaw's reaction to events following "Relevance". The government coverup involves painting her dead partner, Cole (as in: the only person Ms. Antisocial Personality Disorder actually liked), as a domestic terrorist, with predictable results for his family. [[TearJerker So Shaw hangs out around his parents' place, wanting to go in and set the record straight, but unable to because knowing the truth would make them targets as well.]]
** And Reese guessing that Shaw would be hanging around Cole's parents because he would do the same thing in her position, and then going out of his way to track her down and see if she wanted any company. She pretty much tells him to get lost, but as he leaves he tells her that just because they walk in the dark, it doesn't mean they have to walk in it alone.
*** Extra heartwarming because that was something Kara Stanton told Reese when they first started working together, and he tells Shaw a friend of his shared this with him. Even after everything that's happened, even the bomb vest strapped to his chest, Reese still thinks of Stanton as a friend.
** And Finch planting a story in the media which refutes the allegations against Cole and describes him as a hero who died in the line of duty.
* Carter being willing to violate her beliefs by hiding a body from Internal Affairs in order to protect Fusco because she believes that he's genuinely reformed. Also Finch lending her Bear for the purpose. Either he knew why she wanted him or trusted her enough to lend him, no questions asked.
* The Machine's attachment to Finch is quite cute, in the way only a strange, semi-sentient machine can be; it wants to look after him specifically, despite him trying to teach it not to, sets him up with his future fiance, and generally seems to have an intense amount of interest in him for being "just a machine". His reactions to it definitely range in their cuteness, however.
* Reese being willing to forgive [[spoiler:Finch selling the laptop to the Chinese and inadvertently setting him and Kara on their mutually antagonistic path.]]
** Corollary to this, Shaw acknowledging that like her, Reese opens up to very few people.
** Corollary #2: Shaw trusting Reese, even though she doesn't understand all of his personal history with Finch and the Machine. She's going to make a very formidable addition to Team Machine.
