* "Rise of the Turtles pt. 2" After recounting the tale of how he lost his wife and daughter, and Leo agreeing that he lost much (he is no longer human), Splinter says that he had gained much as well- his four sons. (Which he originally bought as pets.)
* There is another subtle, easy to miss moment in the first part, that took a third watching from this Troper to notice. After Raph beat Leo in the training session he says "Nice try." At first it seems like Raph is being a jerk, but then the camera pans up to his face and the look on his face is nothing but genuine brotherly affection. Again this lasts all of two seconds but it is a genuinely sweet moment as this version of Raph has trouble expressing himself to his family.
** To a lesser (and somewhat funny) extent, there's Raph smacking Donnie with his broken staff. If you have a sibling you'll most likely recognize this as simple rough housing. It's pretty clear Raph isn't actually trying to hurt Donnie, and he once again has a brief affectionate look on his face.sode are this due to how adorable it is to see a guy like Raph gushing over his pet.

!!!1x07; ''[[Recap/TeenageMutantNinjaTurtles2012S1E7MonkeyBrains Monkey Brains]]''
* April slowly warming up to Donnie in "Monkey Brains" especially coming to his defense when the other Turtles laugh at him for getting beat up.
** Also from "Monkey Brains," when Donnie returns to the lair after getting beat up his brothers immediately go to help him and only laugh at him after they are certain he's ok.
!!!1x08; ''[[Recap/TeenageMutantNinjaTurtles2012S1E8NeverSayXever Never Say Xever]]''
* At the end of "Never Say Xever" Mikey hugs Mr. Murakami when he reveals that he knows they're turtles and accepts them anyway.
!!!1x09; ''[[Recap/TeenageMutantNinjaTurtles2012S1E9TheGauntlet The Gauntlet]]''
* After [[spoiler: Kirby]] decides to cover the turtles' escape from the Kraang's base, and, as a result, [[spoiler: gets left behind]] (which is [[TearJerker something of a moment]] in and of itself, since April's watching it all happen). Devastated, April hugs Donnie, who goes on to reiterate that they'll get her father back. It's still on the sad side of heartwarming, but says a lot.
!!!1x10; ''[[Recap/TeenageMutantNinjaTurtles2012S1E10PanicInTheSewers Panic in the Sewers]]''
!!!1x11; ''[[Recap/TeenageMutantNinjaTurtles2012S1E11MousersAttack Mousers Attack!]]''

!!!1x12; ''[[Recap/TeenageMutantNinjaTurtles2012S1E12ItCameFromTheDepths It Came From the Depths]]''
* Any scene of Mikey bonding with Leatherhead, starting with Mikey feeding him "pizza noodle soup". Then after Leatherhead talks to Mikey about what a dangerous monster he is, Mikey says "Maybe you just think you're a monster because everyone treats you that way." Maybe he really ''is'' wise beyond his years.
!!!1x13; ''[[Recap/TeenageMutantNinjaTurtles2012S1E13IMonster I, Monster]]''
* The Turtles' reunion with Splinter.
!!!1x14; ''[[Recap/TeenageMutantNinjaTurtles2012S1E14NewGirlInTown New Girl In Town]]''
* There's something very sweet that Mikey immediately goes to hug Leo when he thinks he'd been crying. He might not be the brightest, but he's definitely TheHeart of his brothers.
* Raph's worry when Mikey is knocked out when they're fighting Snakeweed. He doesn't even try to hide his relief when Mikey finally comes to.
** Also, Raph shouting Mikey's CatchPhrase "Booyakasha!" as he delivers the final blow to Snakeweed, for the same reason. Doubles as a SugarWiki/MomentOfAwesome.
** Especially heartwarming when, back in the layer, Raph says that he has no problem risking his own life, but not his brothers.
* Karai choosing to help Leonardo escape from Snakeweed instead of letting him die. Especially notable since Shredder had already given her a stern warning that she wasn't to let him live the next time they met.
** Leo saving the knife she threw at his head as a memento at the end of the episode.
!!!1x15; ''[[Recap/TeenageMutantNinjaTurtles2012S1E15TheAlienAgenda The Alien Agenda]]''

* Mikey and Don's concern for Raph when he [[spoiler: gets bitten by Xever/Fishface.]]
** Especially the way Mikey defends Raph, busting out his most badass moves, often not even taking his eyes off of Raph while fighting off all comers. Doubles as a SugarWiki/MomentOfAwesome.
!!!1x17; ''[[Recap/TeenageMutantNinjaTurtles2012S1E17TCRI TCRI]]''
* When the Turtles return to the lair, April is relieved and shares a brief hug with Donnie.
!!!1x18; ''[[Recap/TeenageMutantNinjaTurtles2012S1E18CockroachTerminator Cockroach Terminator]]''
* Raph pretty much ignoring how terrified he was of the roach when it had Mikey.
!!!1x19; ''[[Recap/TeenageMutantNinjaTurtles2012S1E19BaxtersGambit Baxter's Gambit]]''
* Splinter decides to give April her own ninja weapon, a Japanese war fan. Also heavily overlaps as a tearjerker since Splinter originally planned on giving it to Miwa.
!!! 1x20: ''[[Recap/TeenageMutantNinjaTurtles2012S1E20EnemyOfMyEnemy Enemy Of My Enemy]]''
* Karai saving the Turtles, and Leo saving her in return.

!!! 1x21; ''[[Recap/TeenageMutantNinjaTurtles2012S1E21KaraisVendetta Karai's Vendetta]]''
* Donnie's concern for April is palpable while she's being chased by Karai.
* The turtles are clearly impressed and happy hearing about April's escape from Karai.
** Splinter afterwards says one of the most important lessons about being a Ninja is making it back home.
* When April is fighting Karai, she says she lost her mother. Karai pauses the fight and is caught off guard, even repeating "you lost your mother?" in a shocked, sad tone, and when April is escaping, Karai gives her a...genuinely sorry look.
!!! 1x22; ''[[Recap/TeenageMutantNinjaTurtles2012S1E22PulverizerReturns Pulverizer Returns]]''

* Raph's behavior towards Mikey and Donnie throughout the episode, it emphasizes how much he really cares about his family.
* "I've got this."
!!!1x25 & 26; ''[[Recap/TeenageMutantNinjaTurtles2012S1E25BooyakaShowdownPart1 Show]] [[Recap/TeenageMutantNinjaTurtles2012S1E26BooyakaShowdownPart2 down]]''
* After gearing up for their mission, Raph gives Spike a pat on the head, or rather a tap on the head. Later, he picks up a pigeon and uses it to block one of TCRI's security cameras and once his brothers have snuck past the camera, Raph puts the pigeon down and also [[FriendToAllLivingThings pats it on the head]].
* Raph and Leo have clearly patched up their differences, with Raph rescuing him from falling, and even bemoaning [[spoiler: his DisneyDeath, saying he should have been nicer to him.]]

* A very bittersweet moment when Splinter discovers his supposedly dead daughter is alive [[spoiler:and working with his worst enemy.]]
!!!2x01; ''[[Recap/TeenageMutantNinjaTurtles2012S2E1TheMutationSituation The Mutation Situation]]''

!!!2x03; ''[[Recap/TeenageMutantNinjaTurtles2012S2E3FollowTheLeader Follow The Leader]]''
* The ending where Raph admits that he's happy Leo is home in his own aloof way.
* The fact that Don kinda goes to Raph over his April-based problems.
* We get to see Leo's BigBrotherInstinct again, with him threatening Karai to stay away from his brothers from now on. To add to how impressive Leo is here, he ''still'' manages to make an attempt to help Karai too during this threat, telling her that Shredder is lying to her about Splinter and imploring for her to believe him about this.
* Karai looking at the picture of [[spoiler:her deceased mother, Tang Shen]]. This is probably the first time, we see a girl like Karai with real happiness, instead of the arrogant, snarky kind she usually displays.
!!!2x04: ''[[Recap/TeenageMutantNinjaTurtles2012S2E4MutagenManUnleashed Mutagen Man Unleashed]]''
* At the start of the episode itself, the other brothers join Mikey in watching [[AffectionateParody a parody of Mazinger and Voltron]]. A mild example, but considering [[ButtMonkey how the other brothers usually treat him]], it's rather nice to see them all like something that Mikey is into.
* April, near the episode's end, leads Casey Jones, someone she barely knows, [[spoiler:away from the fight with the Turtles and Mutagen Man]] to protect him without him knowing it.
** She may have also been doing it for the turtles as well since it prevented Casey from seeing them, despite still being mad at them.
* Raph complimenting Donnie for stopping Mutagen Man. Compare that moment to the end of Metalhead.
-->'''Raph''': You did what you had to Donnie.
* Splinter telling Donnie not to lose hope about April's departure.
!!!2x06: ''[[Recap/TeenageMutantNinjaTurtles2012S2E6TargetAprilONeil Target April ONeil]]''
* There's something sweet that April goes to Casey, a guy she only really knew in battle or for work to have company now that she's fallen out with the turtles.
** And that Casey inadvertently gives her a moment of recognition on how accidents happen and friends can drift apart sometimes.
* [[spoiler: April rejoining the turtles after accepting their apology, realizing that it was beyond their control. She even gives Donnie a smooch on the cheek!]]
!!!2x07: ''[[Recap/TeenageMutantNinjaTurtles2012S2E7SlashAndDestroy Slash and Destroy]]''
* Leo's tea party with the little girl. Also doubles as a [[CrowningMomentOfFunny crowning moment of funny]].
* Raph's intense brotherly instinct that comes out when [[spoiler: Slash resorts to beating the crap out of Mikey and Donnie.]]
** Also, when Raph is about to be defeated by [[spoiler: Slash, Donnie and Mikey try to restrain him by jumping on his arms even though they're in no shape to continue fighting.]]
* Splinter tells Raph how to drown his sorrows when a loved one is lost, take comfort in the loved ones you still have.
* When Spike [[spoiler: turns into Slash after getting into the mutagen.]] Its clear that even after his transformation he still cares about Raph with all his heart and truly does want the best for him. Unfortunately this also doubles as a TearJerker later on.
* There's just something about the little girl's lack of fear towards Leonardo. It managed to strike a cord in multiple fans hearts despite her and Leo's tea party being part of a gag.
