Eridians are further behind than humans technologically right? They dont have computers, relativity, quantum mechanics, etc. In fact, Eridians probably dont even know about the Big Bang because their atmosphere would filter out most of the cosmic microwave background radiation we use to detect it. On a human timeline, theyre anywhere between like early-mid 20th century. Rocky's basically a cosmonaut.

So the human civilization is pretty advanced from Rocky's perspective. Rationally he understands this. On a conceptual level he knows this to be true.

Grace wears a yellow raincoat because the flight suits for the mission are yellow. He wears it from the start, when he meets (and tries to escape) Stratt, and is still wearing it when the lab explosion happens and when he's having a panic attack out on the communications array. Hell, he's wearing it when he tells Stratt no and runs for his life. He was always floating around the task force in the colors reserved for the flight crew.
