History TearJerker / GuardiansOfTheGalaxyVol3

--->'''The High Evolutionary:''' ''[rolls his eyes]'' "Aaahhh! Aaahhh! Aaahhh!" ALL RIGHT, P-1-3! You win the crying contest! Now back in the cage!

* After stealing Rocket’s file from [=OrgoCorp=], the Guardians are forced to watch a playback of his horrific experimentation. Everyone, especially Mantis, tears up at the sight of their friend being tortured, and Peter wasn't even ''looking'' anymore. Nebula, who knows firsthand what it’s like to be experimented on, says that Rocket’s suffering was even ''worse'' than what Thanos did to her.

** And just like Group 89, even for the High Evolutionary's plans, they didn't need to die. He could have simply taken off, left them in peace and it would cost him nothing as he went on to try again on another planet, but he instead decided to exterminate billions because he couldn't tolerate the idea of anything he made not being completely perfect.

* When Rocket hears the voice of his creator for the first time in years, he's [[OhCrap on the verge of a panic attack]], which shows how traumatized he is of what the High Evolutionary did to him.

*** When being [[https://youtu.be/x2iBbHP7fOY?si=Z8YWBW_o9rUHk8A_ interviewed]] on The Howard Stern Show, Cooper confirmed that he based the scream on [[EnforcedMethodActing his reaction to his father passing away.]]

* Peter and Nebula's shocked faces when they realize that Rocket isn't with either of them, and since they didn't see the High Evolutionary, they fear he might've gotten taken by him. Keep in mind that it's '''barely''' been that long since they just ''saved Rocket from death'', and now Rocket's stuck with the man who's done horrible things to him in his youth, has been after him and his brain for the whole film, and if Rocket is in his clutches might do ''God knows what'' to him.

** Floor's and Teef's subsequent deaths, being collateral victims of Rocket's first ever usage of guns against the High Evolutionary's mooks. Rocket just turns around and sees his two remaining friends unceremoniously lying dead, as Rocket [[HeroicBSOD lays there in shock and horror]].
*** Even worse: Jjudging by his reachtion, it's likely he [[MyGodWhatHaveIDone knew that he was partially responsible for their deaths]].

*** Even worse, this isn't the first time [[Film/GuardiansOfTheGalaxy Peter could only watch helplessly as someone he dearly loved died a slow and painful death in a hospital.]] No wonder he was so [[TraumaButton panicked at seeing Rocket in this state.]]

*** Becomes much HarsherInHindsight when you remember how dreams work in the MCU. Peter is dreaming of a variant of himself who didn't lose Gamora.
