So we all know that humans pick up the speech patterns, noises, and body lamguage of the people they're around right?
And Grace can't exactly speak Eridian, cause his vocal chords phisically can't, but I imagine over the years it took them to return to Erid, we would've picked up quite a lot of Rpcky's grammar, tone indicators and acoompanyin movements.
So now imagine eridian scientists getting to meet Grace, learning to communicate with him, and figuring that "hey, this human language isn't too bad, you just need to memorise the strange sounds and it's really similar to what we speak, fascinating!", only to pull up an actual video from Earth and go "what the fuck, statement"
