History Heartwarming / GeneratorRex

** Actually most of that episode was pretty heartwarming, especially in the flash back when we get to see just how Rex gets his new family.

----What bothered this troper about the season when Black Knight was in charge was how quickly the Providence agents had betrayed Rex when in previous seasons they treated Rex with respect, even baked him a cake. Then Rex smashes one in the episode Endgame Part 1, revealing it to be an android, meaning that all of Providence's soldiers are robots built by the Consortium. Later in the episode, Rex is on the ropes from fighting the Consortium's HumongousMecha when he is saved by the ex-Providence soldiers who had deserted when Black Knight came into power.

* At the end of "A Brief History of Time" [[spoiler: Breach egts pulled out of the time rift, and dazedly asks Rex if he's real. he assures her that he is]].

* The end of "Riddle of the Sphinx", when Rex offers to help the FishOutOfTemporalWater villain Garan-Set adjust to the present day and tries to save him from his Nanite breakdown. Sadly, the pharaoh refuses, preferring to FaceDeathWithDignity.

* Pretty much all of ''Divided By Six'', when it wasn't being a CMOA.

*** Made even more heartwarming by how [[spoiler:given how Six behaved before his days at Providence, it's most likely that One was glad that his adoptive son had grown to be a better person.]]

*** Holiday's IndirectKiss to an unconscious Six before [[spoiler:[[AwesomeMoment proceeding to go]] MamaBear on Alpha.]]]]

*** Holiday's IndirectKiss to an unconscious Six before [[spoiler:[[AwesomeMoment proceeding to go {{Mama Bear}} on Alpha.]]]]

*** Holiday's IndirectKiss to an unconscious Six before [[spoiler:[[AwesomeMoment proceeding to go MamaBear on Alpha.]]]]

** During a sparring session with Rex, Holiday threatens Six if the session were to go wreck any of her equipment, to which Six just answers with a small smile. It's more than enough clue that some things didn't change.

* "Six Minus Six" despite being an absolute tear jerker for the implications for Rex and Six's relationship [[spoiler: Six forgot Six years, he's known Rex less than two]], had some great bits, finally culminating in this exchange:

* During "Heroes United", White Knight chooses to stay by Rex's side to help him fight the Big Bad. It really shows the change he has gone through because of his respect for Six and Rex. From {{Jerkass}} to ReasonableAuthorityFigure, I dare say.

* Rex meeting up with Six,Holiday and Bobo after they've gone underground.

* "Lions and Lambs" is chock filled with these revolving around Breach. [[spoiler:When Breach is given time-travel abilities by Van Kleiss, Rex offers to bring her in. He tracks her down and most of what follows is the two becoming friends, and Breach even tries to defend him from Van Kleiss. Things are screwed up when White Knight insists on bringing her in personally, making her lose faith. To get it back, Rex restores her powers (the time-travel device was blocking them). Kleiss thinks she'll use it to send him through time, but she zaps Kleiss instead. Unfortunately, the device goes out of control without Kleiss to shut it down, trapping both her and Rex. before they vanish, she tells him that, while she isn't sure it was real... she was happy to have a friend. They both hug as the time vortex envelops them.]]

* Kinda surprised no one's added the part where Rex hugged Six when he found out he was out of his coma, not to mention that Six actually said something positive in response to his reaction. It made this troper's heart flutter and dance.

* Six and Rex have a few brief moments in ''Crash and Burn'' that show while [[spoiler: Six's memory is still gone]] after the TimeSkip, he still cares about Rex in his own way.
* During Heroes United, White Knight chooses to stay by Rex's side to help him fight the Big Bad. It really shows the change he has gone through because of his respect for Six and Rex. From Jerkass to Reasonable Authority Figure, I dare say.
