He’s her best friend, and she doesn’t even know it. They’re so close, that in the book, people think they’re sleeping together, and poor Grace is so confused because he thought that was his platonic work wife, wdym people think we’re sleeping together, that’s my person that I crack jokes with and then she glares at me because they’re not funny.

She’s softer with him than anybody else and is only ever vulnerable around him. We see in the movie, he’s the only one who ever gets her to smile, and sometimes even laugh, and then she serenades all of them, but mainly him, and he stares at her with those big, shiny eyes so lovingly, and she points at him when she sings, “everything’s gonna be alright”, and then she gives him those eyes, so loving.

And then she’s trying to stop herself from crying when she’s sending him away because, against her will, he’s become her person, and somewhere along the way, she’s become his, and they will have forever ended this relationship on bad terms, and nothing can fix that.

It’s a platonic tragedy. It’s a platonic love story. This is something we don’t get often, or, like, ever, and it’s deep and it’s tragic and it’s sad.

But even after, Eva’s still taking care of him. Packing clothes she knew would bring him comfort. Programming the ship to know how he likes his coffee. And Grace is still watching out for her, speaking to her directly in his video logs, with that same lopsided smile he used to throw her way.

He uses Rocky’s sign for goodbye, and she uses it back, and how did this book and movie give us such a deep platonic friendship because, guys, this NEVER HAPPENS.

Eva Stratt:

The Eridians figure out how to safely dock the Hail Mary to the top of the space elevator structure. A greeting party of Eridians gathers to welcome Rocky back. Introductions to Grace are made (if this is a version of the story where Grace is in a state to introduce himself, health-wise). The Eridians escort Rocky further in and down, leaving Grace safe in the Hail Mary for the time being.

At the exact point where Grace's heartbeat starts to peter out of Rocky's constant spatial awareness, Rocky just. Stops walking. Completely stops dead in the middle of a hallway with no warning. The other Eridians keep going for a step or two before realizing he's stopped and also stopping, confused. They ask him what's wrong. He doesn't answer.

From the instant that the outer hull of the Hail Mary came between Rocky and Grace, Rocky has been fighting the impulse to sprint back into the ship and double-triple-quadruple-quintuple-check that Grace is still okay. That impulse has been growing stronger and stronger with every step he takes, until this moment, when one more step will carry Rocky out of the range where he can keep tabs on Grace without even consciously thinking about it. It feels like Rocky physically can't move his legs. What's happening to him? Is he going to sleep, and that's why he can't move? He can't be -- he just woke from sleep barely 1.5 Earth days ago.

Adrian steps toward Rocky with a croon of concern. Their carapace tilts away, in the direction the group had been headed. Aren't you coming?

Old instincts kick in and Rocky automatically moves toward his mate, one step, two steps, three--

Grace's heartbeat is gone.
