History TearJerker / Hereditary

** Peter's HeroicBSOD right after Charlie's death. He already knew she was dead but didn't want to believe it, maybe even having heard her head smashed off her neck (as he later heard his mother's head fall off) or seeing it in the corner of the rearview mirror. He doesn't dare look back, already knowing she's already dead but not wanting to make it real, ''finally'' works up the courage to call out to her as if hoping he'll hear her voice and that'll make her okay again, and eventually cries in silence and drives home alone with her little body in the blood-soaked backseat. The ending of the movie has him thinking things are so nightmarish that he must be asleep and trying to wake up, which is probably what is happening in this scene too with him quietly going to bed and unable to sleep - and then he hears his mother's screams and knows it's real and there's no going back to his old life, ever again. He drove out with his little sister and brought their parents home a headless corpse, all because of a few stupid, simple mistakes that happened so quick, all because he was an annoyed older brother and wasn't paying closer attention. How could a teenager possibly handle something like that?

* The argument at the dinner table between Annie and Peter regarding Charlie's death and both attempting to pin the blame on one another for what happened. What makes the dinner scene so heartbreaking is the fact ''[[BothSidesHaveAPoint both]]'' know they are at fault, but they're hurt that the other doesn't want to admit their own part in the lead up to Charlie's death. Annie's emotionally broken and stressed from the death of her daughter and lashes out at Peter for driving into that power pole... And then Peter bluntly asks her [[ArmorPiercingQuestion why she forced Charlie to go to the "barbeque" with him in the first place when she made it clear she didn't want to go]]. Tellingly, Annie is incapable of coming up with a response to that, as she slowly yet completely breaks down in silence and then leaves the table.

* During the climax, as Annie is pursuing Peter, he pleads with his "Mommy" to listen to him.

* Steve's breakdown in his car while bringing Peter home, where he finally begins to sob. Considering we've spent half of the movie seeing Steve as a very calm if stern man, seeing him break down at how far his family is collapsing within itself is heartbreaking.

* When Peter is heading up to the treehouse, we get a shot of the dog's corpse... And Peter doesn't even notice it. At least we ''don't'' get to see how the poor pet was murdered.
