History Heartwarming / Ben10AlienForce

** The episode opens with Kevin [[DrivesLikeCrazy driving like crazy]], Gwen next to him and a seemingly-dying Ben in the backseat...and it turns out Ben just has a nasty cold and Kevin is taking him to get ComfortFood at Mr. Smoothy's. While PlayedForLaughs once [[NotSoDire the truth is revealed]], it really shows the lengths Kevin will go for Ben's well-being, especially coming from a guy who used to want to kill him.

** And as it turns out, Julie thinks Ben being able to turn into aliens is cool. She wasn't aware of the alien things at first, and seems to think his powers are cool. It was the first time since Kai that a girl knew about his powers and he sounded relieved that she assured she thought the alien powers were cool.
* Pretty much all of 'What Are Little Girls Made Of'. Specifically, while Verdona may have come off on the wrong foot with her grandkids in, she still loves her husband and came to their spot when she thought he had perished and, while she left, it was on better terms with their grandchildren than before.

* 'In Charm's Way' has Ben and Gwen hanging out at night outside of Gwen's house. She then tells him she's going back to look for a cure for Kevin much to Ben's dismay of wanting to hang out a little more.

* While played for laughs, the opening of ''The Secret of Chromastone'' where Kevin DrivesLikeCrazy, to get a seemingly-dying Ben urgent attention, only to get him a smoothie at Mr. Smoothy's after he gets a cold, really shows the lengths Kevin will go for Ben's well-being. It's something coming from a guy who used to want to kill him.

** Also the way he affectionately says "Hang on, hero!" to an ailing Ben in the backseat in a manner like a protective big brother would.

* PapaWolf moment of Rath in "Con of Rath". After saving the little ice cream-like prince from a stomach of a newly introduced villain, he threatens to make a sweater from his ORGANS in case he declared war with another alien race. Also qualifies as the [[Awesome/Ben10AlienForce Crowning Moment of Awesome]].

* Kevin embracing Gwen after she frees him from the [[BodyHorror horror-of-a-transformation]] into a Taydenite being.

** Pretty much anytime Reinrassic III and Ben interact, knowing how much the latter has caused the former's character to develop from a racist supremicist to one of Ben's closer friends and staunchest allies. Added "D'awwww" points for Reinny's unintentional pet name for Ben: "[=BenbenTennyson=]."
*** Not to mention the full weight of his arrival in "War of the Worlds". While he seems to reject what Ben was trying to teach him in "Alone Together", clearly having time to think allowed it to sink in, not only that, but he returned to save Ben and help his lesson be spread throughout his race
* The entire ending of "Voided". Period. To be more specific, not only does Ben save the world, but also he and Gwen find that Grandpa Max is still alive. Then, while Gwen is trying to get Ben back through the portal she opened, Kevin reaches in to help her and utters the following line:
-->It's time to come home, Ben.

* The last five minutes of "Paradox". The team and Professor Paradox help stop the strange temporal monster, who they discover is none other than Hugo, the professor's assistant in the experiment all those years ago. By changing the outcome of the experiment and saving Hugo, they not only saved the day, but let Hugo live out his life. He returns to the scene and happily greets Paradox. Paradox in turn is happy to see his old friend and he proceeds to show him a "behind the scenes" tour of creation.

* PapaWolf moment of Rath in "Con of Rath". After saving the little ice cream-like prince from a stomach of a newly introduced villain, he threatens to make a sweater from his ORGANS in case he declared war with another alien race. Also qualifies as the [[Awesome/Ben10AlienForce Crowning Moment of Awesome]].
* "Inside Man": Ben rescuing a [=DNAlien=] rogue from being taken back to their ship, along with two words: "No sacrifices."
* Pretty much all of 'What Are Little Girls Made Of'. Specifically, while Verdona may have come off on the wrong foot with her grandkids in, she still loves her husband and came to their spot when she thought he had perished and, while she left, it was on better terms with their grandchildren than before.

** Also the way he affectionately says "Hang on, hero!" to an ailing Ben in the backseat in a manner like a protective big brother would.

* The end of "War of the Worlds": after 2 seasons, instead of destroying the Highbreed or beating them up, Ben saves them.
** Not to mention Max and the Plumber's helpers returning from the null void.
