* Quaritch, starting his speech on staying safe on Pandora, makes a promise that he will try his damnedest to get everybody home safe. It slips into tearjerker when he confesses that he will not always succeed.
* Jake's boyish bliss as he finds out that he can walk and run in his Avatar body.
* The entire Na'vi tribe joining hands during Jake's initiation ceremony.
* Jake and Neytiri at the Tree of Souls, just before the battle
* ...then afterwards, with Neytiri holding Jake's human body
* Neytiri treats Jake's "fainting", and indeed the entire nature of his human/Avatar duality, more as a medical condition than anything else. The other Na'vi question whether he even counts as a person, and she's just like "dude falls down sometimes. Deal with it."
* Some of the smaller moments of Jake being accepted into the clan are very sweet. The other ''Iknimaya'' initiates cheer unreservedly for him after he bonds with his ikran, while in the extended cut, one young girl reaches out to him with a friendly smile on his first night in Hometree.
* When faced with a stampede charging their position, an AMP soldier tells his squad to fall back. He [[VillainousValor holds his ground and goes down shooting]] in an effort to buy them the time to move.
** Similarly, the soldier who manages to shoot Tsu'tey was trying to protect a wounded comrade.
* The concern the Omaticaya show for Grace’s avatar when she “passes out”(the link is suddenly interrupted) [[spoiler:during the evacuation after the destruction of Hometree]]. They even put her on a stretcher so that they can get her to safety with them. Later, when [[spoiler:trying to transfer Grace into her avatar body because she was mortally wounded]], the fact that they kept it safe from harm helps to show just how much she is liked by them.
** From the extended edition, Grace's nickname by many of her former students was "Sa'nok" which translates to "Mother." Heartwarming and Tearjerking when you find out [[spoiler:the school was abandoned because Neytiri's sister and several of her friends were shot by RDA mercenaries in front of Grace and her students after lighting a Bulldozer on fire, thinking Grace might have been able to protect them. "Pain like that, it comes back through the link" indeed]].
* After Jake is accepted into the tribe, Neytiri tells him that he can now choose a woman. She lists a couple of other potential women for Jake to choose, after which he says he doesn't want them.
--> '''Jake:''' But I've already chosen. But this woman must also choose me.
--> '''Neytiri:''' She already has.
--> ''Cue BigDamnKiss''.
