[in the voice of someone who hasnāt even seen the movie] imagine if Grace came back. Imagine if through some loophole in science, Eridians and humans were able to make contact and regularly interact with each other.
Imagine Eva seeing Grace again.
Oh no no no donāt look at me like that. Heās not mad at her. He understands that she did her best in a horrible situation with no good answer. So no heās not mad at her.
Itās so, so much worse than that.
Eva didnāt even realize the difference between Graceās friendly and Graceās politely cordial until suddenly she had experienced āfriendlyā and sent him away, okay with never experiencing it again.
But then he comes back. And he IS friendly, downright loving towards the rock people following him around. But heās politely cordial to Eva. He answers her questions when she asks them but doesnāt ask any of his own. He turns to the big brown rock when it chimes and tells it in that tone of affectionate disbelief, āRocky, you canāt say that to her!ā But then only tells Eva when she asks, āyou donāt need to worry about what he said; he didnāt mean it, heās just mad.ā
Imagine Eva attempting to go for a hug when she first sees him again, and he either just tolerates it, or even worse, he politely tells her ānot yet,ā ānot now,ā or even just āno.ā
It was easy to pull the lever when you thought youād hear the trolley roll over one person you loved, and theyād scream and train wheels would roar and with a splat, that would be it. But no; the one life she threw under the trolley, even though it was someone close to her, closer than she ever let anyone else, did not die. He managed to escape and survive the trolley and even managed to make the universe a bigger, better place.
But now heāll never forget the look on her face when she pulled the lever. And things will never, ever be how they were because even though it was justified and he understands and doesnāt blame her, it hurt, even though the trolley never touched him.
It was better when she thought she was killing her friend, because she wouldnāt experience his friendship again, and neither would anyone else.
Now, everyone gets to experience his friendship.
