i put the "NOT" in astronaut!!

bc in no way can be read that she was always gonna send grace on the hail mary, or that she suspected or knew she was going to have to send him.

when she sings, it is absolutely to him, but it's to reassure him that she knows she's going away but that she's coming back. she's telling him to hang in there, that it's going to be hard but that she believes in him and that she will come back when the time is right and they'll meet again somewhere far away from here.

that's the captain of the ship telling her first mate "youre gonna have to run things when im gone but its okay bc i believe in you and youre gonna do fine. I'll be back soon."

she KNOWS she's a scapegoat. she's been planning for her arrest and eventual escape the whole time on the backburner.

and then the disaster happens and she has to send her second in command, her friend, to his death or they all die.

and suddenly there is no more "we'll meet again someday" bc she's never gonna see him again. even if everything goes to plan and she escapes and the beetles arrive with a solution-- she loses grace forever.
