History Heartwarming / GuardiansOfTheGalaxyVol3

* While his attempts to charm Ura appear to humorously fall flat, Peter's original plan to simply appeal to her better nature and believing she's a decent person and ask for her help ''does'' work; Ura allows him access to the systems and gives him a chance to rescue the Guardians. Gamora rolls her eyes, but she does seem slightly impressed that he was able to convince her without needing to use violence.

** At the start of the film, we're introduced to Peter drunk and in a bad mood, trying to pick a fight with Rocket when he sees that he has his [=MP3=] player. Instead of fighting back like he did in previous films, Rocket (along with Nebula and the rest of the Guardians) help put him to bed, implying that this isn't the first time they've helped a distraught Quill.

As the final swan song of the original Guardians of the Galaxy, it makes sense that James Gunn would do his best to warm our hearts.

** Nebula is completely ''speechless'' and unable to respond so Mantis steps in to verbalise for her that they all love Rocket very much and relieved at his recovery.

** A minor detail but as Rocket plays the song, Kraglin is seen joyfully laughing. He's probably heard Peter play it multiple times during his Ravager years and is likely happily reminiscing about his former Captain.

-->'''Peter:''' ''(fond and tearful smile)'' [[GoodPeopleHaveGoodSex Like you wouldn't believe.]]

* The reason the bat woman and her family agree to help the Guardians reach the ''Areste''? [[BecauseYouWereNiceToMe Peter noticed that she had cut her leg after falling and offered her a handkerchief to help stop the bleeding.]]

* When Rocket is revived, Peter gently pulls him into a hug, overjoyed and relieved as hell to see his best friend alive and well thanks to his efforts, and Groot joins in not long after. Even Gamora (who was apathetic to his condition and considered selling Rocket to the High Evolutionary earlier) [[WhenSheSmiles cracks a smile]], clearly happy to see him recovered. Even sweeter is Rocket gently nuzzling his head on Peter's shoulder and placing his arm around one of Groot's vines.
** Upon hearing Rocket speaking on the communicator alive and well, Nebula bursts into TearsOfJoy.
** Nebula is completely ''speechless'' and unable to respond so Mantis steps in to verbalise for her that they all love Rocket very much and relieved at his recovery.

* Peter visiting his grandfather on Earth. The way the old man breaks down in shock and delight at seeing his once-thought dead grandson is sure to break a few hearts.

* When Nebula snaps at Drax for being TheLoad, Mantis jumps to his defense. Her words on why he's of value, that he loves them and makes them laugh, can be seen as LeaningOnTheFourthWall.

** For that matter, Ayesha’s love for her son too along with her motive being to try save her people in this movie. The very first time we see her here, she’s holding her “baby”, distraught at Adam’s injury and defending him to her God.

* When Rocket is revived, Peter gently pulls him into a hug, overjoyed and relieved as hell to see his best friend alive and well thanks to his efforts, and Groot joins in not long after. Even Gamora (who was apathetic to his condition and considered selling Rocket to the High Evolutionary earlier) [[WhenSheSmiles cracks a smile]], clearly happy to see him recovered.

* Nebula realises how good Drax is with children and acknowledges that he is better suited to be a father than a destroyer.
** She does this in the middle of an argument between Drax and Mantis, where Drax insists on coming with Mantis on her journey to keep her safe. After everything in this film, it has given Nebula a new appreciation and respect for the both of them, she arranges things so they don't have to part on bad terms, by giving Drax a purpose so Mantis can, without guilt, find her own.

* The fact that despite all that's happened in the film, and how marketing implied that AnyoneCanDie, particularly Rocket, ''nobody'' from the Guardians died, although it was close in few cases. An EverybodyLives situation was ''much needed'' after Yondu's sacrifice in Vol. 2.

* Ravager Gamora finally understanding Groot without even noticing at first. Especially when you consider that Guardian’s Gamora was like a mother to Groot and then she was killed by Thanos. Suddenly there’s this stranger who looks exactly like his mother that doesn’t understand him and is annoyed by his PokemonSpeak. It must have been hurtful for Groot. But when she finally understands them it means there is a bond between the two. It’s nice for Groot to get that back.

* Gamora and Peter's mild flirtation at the end of the movie. It proves that while "our" Gamora is dead, a part of her ''is'' still alive within this younger version of her, leaving a very strong possibility that one day they will be together again. At the very least, it's still heartwarming for Gamora to see why her alternate self fell in love with Peter.

-->'''Nebula:''' Drax, you were never meant to be a destroyer. You were meant to be a dad.

--->'''Mantis:''' I love you guys. I love you all ''so much.''

-->'''Lylla''': You were always the center of this story. You just didn't know it.

* As the ship explodes around them, when Peter comes across some random mooks, with guns drawn, he essentially offers to let them come with him if they just holster their weapons. It's show Quill's heart that if he doesn't have to he won't kill someone even low level foot soldiers.
