"you want this to happen"
"they were just waiting for this to happen"
"my body was an open wound... i'm healing"
kinda felt like they forgot (or cut) the scene where beth finds out martin is literally 5 years old??? which like, idk, i feel like there's different things to take from this but it's definitely weird. his maturity level seems kinda unclear, like generally he feels like a young adult just lacking socialization, but then there's bits like him jumping on the bed that suggest like, he is still a child. can this be part of the trans reading? what in the text is accelerated development might be read as arrested development, which is to say he's in some ways 20 and in some ways 5, as transness often involves being stuck at some particular age, read as like, kinda the inverse of eli in ltroi. martin has physically/externally matured to adulthood, but underneath he's still a child. alright so there's that. so then, in what ways is his metamorphosis first puberty, and in what ways is it second puberty? idk we'll come back to that.
another thought is, following histories of the transgender child, how does plasticity / racialization / eugenics / intersex / etc fit in here? thinking of embodied plasticity and volatility re: bartok's desire to control "the form and function of all life on earth," he misunderstands that the body and embodied plasticity have their own agency and cannot be so easily corraled [sic], to his ultimate comeuppance / ironic punishment. his motives are almost explicitly eugenic, if not like, explicitly explicit (his whole thing about being god lol).
ok next, martin's whiteness makes him valuable, hence he is given at least the facade of care / family / agency / trust / etc. he could've been kept in specimens with the dog, but was instead given birthday cakes, told to consider bartok a father, given a "job" (do they pay him??), even given placebo injections for his peace of mind. ok so intersex stuff. martin is born ambiguous, if you will, and out of the goopy pod thing the doctors produce a normal looking (read: white) baby. martin is misled about the nature of his "condition" and subjected to extensive medicalization. eventually the truth becomes clear thru the transformation of his body, and he learns that not only was he misled, but that this was his value to bartok in the first place - he is not a son but an experiment.
so then where does this leave us? martin tries to escape his body's true nature but is unable to do so, and eventually accepts it ("i'm healing"), but on his own terms rather than bartok's. as such, he maintains lucidity in bug mode and leverages his metamorphosis to enact vengeance on bartok and co. this ultimately allows him to be born a 3rd time, again in human form, presumably "cured" (why is he still an adult rather than a small child? bc handwave i guess).
idk i feel like there's a lot we could take from all of this. i do think the ending is kinda unfortunate in its emphasis on cure - in order to become fully human, martin must attain normative chromosomal structures and stuff. in one sense i like him being reborn as an adult bc again, trans stuff, but i think storytelling-wise him being a baby again at the end would've been more effective. :shrug:
