May I just say I think this is my favourite scene in the movie in terms of emotions from Ryan.
Grace has just discovered the Taumeba eats the astrophage, he has the literal cure for Earth's and Erid's problem under the microscope right in front of him, he can save everyone!
And he wants to celebrate this, he's joyously happy, but he can't, because turning to see Rocky still not moving, still dead as far as he's concerned I mean he doesn't know he's going to ever wake up. And he can't celebrate. How can he? He can't save Erid without Rocky telling him where to go, he can't do any of this without Rocky, and he's crying tears of joy and frustration and relief and sadness and fear and loneliness all in one, and it's just an amazing portrayal of emotions.
