Humans are pretty prone to mimicking noises. like even subconsciously. sometimes we even unintentionally pick up entirely different accents. and you literally can't tell me you've never meowed or woofed or chirped back at a cat/dog/bird at least once in your life (unless you are physically/audibly unable to do so).
So Grace 1000% starts picking up and mimicking Eridian noises.
One day, Rocky will be working on something, only to freeze as he hears Grace behind him suddenly exclaim in fluent Eridian "SHIT!"
Turns out Eridian swear words are usually expressed in the same decibel that humans can whistle in.
