Callous and Capricious

Also the other time we were at the same buddy's house and he didn't have a potato masher, so we used a wine bottle.

"Aw but eridians would be so horrified at how violent and evil humans are"

Eridian history is as complex and varied as human's (canon), there's kind eridians and violent ones, greedy ones, selfless ones, monstruous ones you can't even mention their names in polite company and heroes that have carried their people foward.

For every human killing their own kin for resources, there's an eridian who has torn their own kin apart for fun

For every human who dedicates their life to helping people, there's an eridian who did the same.

Be creative, folks! Make your rocks evil!!

"Eridians don't feel any sexual drive because they just lay eggs next to each other. They must find humanity so disgusting."

That is also mating, folks!! Frogs, fish, etc, also literally just lay their genetic material next to each other, and a few will fight to the death in order to do it. Basically all species have an instinct to reproduce; its a very risky and energy consuming task, there's gotta be a strong drive urging them to do it otherwise they just. Won't. And then go extinct.

Humans aren't gross for being intimate, that's just the catholicism speaking.

"Eridians must get so annoyed at the sheer amount of specific requirements Grace needs to survive"

Their eating habits include:

- finding the specific prey animal with the nutrients you are specifically needing rn

- hunting it down, then tearing it apart with your hands piece by piece

- cracking your carapace in half (exposing you to Every Pathogen), shove said food into your stomach, hurry to seal the wound before you die

- passing out for several hours, completely helpless.

Grace just bites anything edible and swallows, body does the rest.

For every gram of B12 and Vitamin C Grace needs, theres an eridian sick because they couldn't get enough mercury.

Also the life of their planet is so sensitive to enviroment changes, a couple degrees temp drop was devastating (also canon). For an animal that has no carapace and takes damage from EVERYTHING, humans are pretty resilient.

"Eridians scientists would experiment on Grace unethically/Erid would kick Grace out"

My fella. My sibling in everything but blood. Listen to me.

If an intelligent alien came to earth after saving us from certain doom, the scientific community would host a fight pit in order to select the team who will care for/interact with this alien.

Does the alien need more food? Cool the temperature down? Does it need me to sacrifice my kidney to it? Hell, have BOTH my kidneys, have my WHOLE ARM, so long as I get to write about its phisiology.

AND its a scientist alien and wants to study me back???? It'd be the peak of my whole career, id die happy.
