"password is incorrect"

When Simon finally opens up to Grace about his past, being in prison for 16 years, telling him about Filament Station, about Eden- Grace suddenly stops him.

Because Grace is very good at math.

Simon seems to be in his early 30’s… meaning if he was locked up for 16 years he could have been anywhere from 13-18 at the time of the attack. Grace had been a middle school teacher. He had taught that exact age range, before watching those same kids that he taught grow and go to the high school in the next building over.

The idea of one of his kids being held responsible for 65 deaths and then sentenced to prison is enraging enough. The more he learns about the cult Simon was raised in- it sets off every alarm Grace had ever had as a teacher.

The fact that Simon was a child soldier and Grace was a child educator is not talked about enough.

Grace was put into coma by the people who cared about him. They (especially Yáo being Yáo) probably double-triple-quadruple checked everything. They watched him sleep for those first few days — I doubt they went into coma immediately after leaving Earth's orbit. They probably talked to him, assuring him that he'll be okay.

Ilyukhina's coma procedure was probably supervised by Yáo. He made sure that everything was in order, but — he is just one man and he is not a doctor. There was much more room for mistakes.

When Yáo went to sleep, he was alone. He had to rely on the technology completely.

jon: I'll do you one better, I'll lie about my age by 10+ years so I can be respected in this field.

Like yeah sure, Grace is happy to be going home once Rocky offers the fuel. But do you think, somewhere in the back of his mind, he's worried about the fact that Grace volunteered for a suicide mission in the first place?

Then more things happen and Grace takes risks that put his life in danger, and yes its so they can complete their mission. But Rocky might still worry that Grace is still trying to die.

But then they succeed. They get the answer to save their worlds, and they each head home. Alone but alive.

Then the taumeoba escape. Rocky knows he is doomed. Unknown if the same fate has met Grace. If this is another opportunity for Grace to die.

But then Grace is there! He's knocking on the door! He came back to save him!

But now he's going to die, because theres not enough food for him to eat to get back to Erid

Rocky figures out a solution. Grace might not be able to eat Rocky's food, but he can eat taumeoba.

But good grief, can his friend stop almost dying? Please?

Do you think Rocky is actually relieved to learn that Grace didn't actually volunteer for the suicide mission. That he had wanted to Not Die so badly he had to be forced to go?

Relieved that his friend is not actually actively looking for chances to die
