Gimmie Eridians who are absolutely heartbroken to hear that humans where so desperate and so scared that they where willing to part with not just one Grace, there were three of them! Gimmie Eridians touched to find that the humans planned a way for their sacrifices to be as comfortable as possible. Gimmie Eridians who send earth a message saying “We know it must have hurt to send your heroes to die, but one made it and he’s safe here. We lost 22 good Eridians on the journey we would have lost 23 if not for your Grace.”

Grace wasn't sad and lonely, he was happy, he had a good life, he very much did not want to die. They have to do a looney tunes chase sequence and drug him because Grace was *very* unwilling to be the sacrificial lamb. Humanity's savior was dragged kicking and screaming into the role and called selfish for daring to be a coward, as if most of us wouldn't be.

And then he befriends Rocky, who never demands a sacrifice from him, who willingly prolongs his journey home so Grace can go back to his. Rocky has a mate back home and his species depends on his return, and still risks his life to save his squishy human friend. And Grace returns the favor.

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.

Like imagine being a modern day sailor navigating the Pacific with GPS and strong hulls to protect against the raging ocean. And from portside you see like an honest to god viking ship. Except its made of some high tech carbon fiber material. But like, its still very definitely a viking ship. You can clearly see there's 24 oars along the hull where sailors are supposed to use to manually row their ship. Also the ship is leaking and theres like one little dude on board whos skittering around patching the holes constantly. Also this little dude is blind and doesnt know about water. Thats how insane Eridians look being an interstellar species without computers or radiation shielding.
