i got more fun phm ideas if anyone needs writing ideas!
feat. weird fleshy human brains!
kay so methinks that the species of sentients with brains made of literal crystals who (based on how rocky seems to behave) seem pretty logic/facts driven and also may be a little rigid in terms of potential adaptability?
i think that the eridians would be a little freaked out or bewildered or something when grace explains that his brain changes entirely mid-crisis to produce entirely different chemicals that let him operate better under high stress situations. feat. cortisol and adrenaline which can do shit like increase breathing, heartbeat and blood pressure and slow the digestive and reproductive systems to divert more oxygenated blood to the brain and muscles. plus they can shut off pain receptors allowing the body to push past its limits and do things it normally blocks us from doing because weād hurt ourselves (ie. shredding our muscles lifting cars, running with broken bones, etc).
and then similarly, our emotions are also at least partially driven by chemical-based reward/punishment systems our brains evolved. love? thereās a chemical for that. happiness? thatās a chemical. sad? thatās actually a lack of chemicals. literally every emotion can cause shifts in brain chemicals and hormones.
like imagine trying to explain anxiety? my species bodies and brains evolved to make us feel bad when we might be in danger or socially ostracising ourselves so that we donāt do that. why avoid social outcasting? hard to survive on your own, usually being by yourself with no infrastructure in ancient times meant death or a lot of struggle. and then trying to explain an anxiety disorder??? oh yeah my brain is not built right and registers things as threats or social ostracism way more often than it should. brain freaks out over nothing and i get to suffer for it :/
the fact that things like sadness, grief, heartbreak, depression, rejection, other negative emotions can physically hurt to experience. i think theyād be deeply concerned over that one. (cue grace being like āi told you itās a reward/punishment system, why are you surprised thereās punishments?ā).
the fact that (due to The Chemicalsā¢) prolonged stress can actually have negative impacts on physical health. including but not limited to; potentially fucking up the thyroid and tanking energy production causing fatigue. altering brain structures causing depression, anxiety, brain fog/focus issues and memory problems and trouble sleeping. muscle tension and resulting tension headaches. gastrointestinal and cardiovascular issues. and also it can fuck up your immune systems making it easier to get sick and take longer to heal wounds.
the way that the long term stress of working on and the hm project and then being sent on the mission having permanently changed the structure of his neural pathways meaning his brain is still acting on the assumption that itās in danger in some way and reacting accordingly to things like itās in danger even though heās safe now. and that this happens often enough that humans have a well-documented history of this issue and a name and diagnostic criteria for it (ptsd). honestly explaining human mental disorders and illnesses would be so fascinating for a species that has (likely) unchanging brains made of crystals.
the way the human brain can just decide some memories are not important enough or too debilitating to keep and erasing or blocking them out. the way we use sleep to file short term memories to long term storage (hence why you get poorer memory if youāre not sleeping well).
the fact that a significant part of growing up for humans is learning how to regulate yourself and your behaviour and work and function through hormonal and chemical changes and imbalances.
anyways thereās so so many fic opportunities in there! let the alien rocks poke grace like the strange creature he is! let his existence be lowkey horrifying!
endless angst and hurt/comfort potential!
or maybe in your ārocky becomes a humanā fics you could be a bit evil and make him completely debilitated and/or overwhelmed by his suddenly very biologically and chemically backed emotions that he has no experience regulating or working through!
idk i just feel like ppl could be doing more with the inherent differences between a species of rocks with hydraulic mechanical movements with more rocks and a species of very squishy fluid creatures made of mostly water with brains made of water and fats. be creative! invent your own eridian biology for funsies to make grace seem comparatively more strange/horrifying/impossible/astonishing/etc.
