There is a moment, after the beetles arrive on earth, after earth receives their colony of Taumeba, after they watch a few of grace's logs, while they are still planning how best of deploy the astrophage predator, while the world outside the window was still endless winter. There is a moment; a moment of thanks and silence to the dead crew and to the man that saved the world despite it all and his unlikely friend. A toast to a man who didn't want to go to space and saved earth anyway and then decided to save an alien too.
Now instead of coming home, something unheard of to begin with; he was going to go to an alien planet, where he would likely starve to death. Knowing all of this, the new petrova task force raise their glasses for the heroes of the stars. Whether they lived or not it makes no difference. They all hope he is happy, and warm. Wherever he ends up.
