But if you use a ladle, you'll be fine.

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.

Imagine for a second you are Adrian surname The Eridian. Your spouse has been missing and presumed dead for around a decade, and suddenly one day an alien spaceship comes into orbit. And you cheer "Yay alien species have realized we have the same problem and have come to either give us a solution or join or efforts, too bad my mate is still gone."

Except he is not actually gone, because the eridian equivalent of a carebear decided to save them. And he doesn't want anything in return, in fact he is well aware that he might die A PAINFUL SLOW DEATH, shortly after fighting just to get the love of your life back to you. But it's ok :) because Rocky (yes he gave them a silly name) is my best friend! Oh- Are you ok-
