what we love about PHM, both the book and the film, is that this story neither censors nor glorifies death.
interruption: we had a dream. we went to rewatch PHM with a friend in a cheap apart hotel like room with blue walls. that version was different, though; we were late and entered the room when Grace, in his silly movie red EVA suit, was exploring some sort of an asteroid. the asteroid was a very small one, almost a ship-like (speaking in Eridian ship sizes) and had a brass or even golden pyrite coloured scaly surface. the scales vibrated while Grace was climbing cautiously across the surface, and we could heard the sound as if it was for Grace (actual sound design of the real film was impressive!). eventually, Grace found a golden plate with engravings buried among the scales. it was somewhat intact, but later, aboard the Hail Mary (presumably), he discussed that founding with Rocky, as it was not the first, and came to the conclusion that, while Grace was absent, humans invented some type of space missiles, launched them and destroyed both Voyagers.
slowly coming back: we will take this idea for our thermonuclear AU.
back, finally: even in the dream, Grace didn't say something like "there's no Voyagers/they undid them". directly, "humans destroyed the Voyagers". and, in the wake version of the story we all know, there is no "unaliving", "they aren't with us" and stuff like that. a transparent Astrophage cell. grey skin of space mummies which once were humans, breathing, friends and crewmates. Rocky, saying directly - or Grace, translating in such a manner - "died". both taking turns in almost dying. and, no, the fairy tale like movie ending doesn't change it, it has an effect of "until we die, we're going to live the hell out of it".
death is inevitable; death is the force no one can actually fight and win in the end; death is a part of the universe. when a human faces death, it shows what this human is; when a human dies, it shows what the human's life was about. same about Eridians, we think.
Grace is brave, if we look at his reaction to death. he doesn't try to ignore it, to deny it, to avoid or censor it for himself. yes, he makes an attempt to avoid the topic when the kids in class are curious about the Petrova Line, but not for long; and yes, he doesn't tell Rocky he won't go home because he's meant to die here, but did Grace actually forget the fact in the movie? we have doubts.
death makes you a person. and speaking in euphemisms about it doesn't make anyone immortal. we understand a lot of real trigger warnings, but death? there will be a day in everyone's life when death will come for the first time.
