In love with the idea that since the eridians clearly have space tech, even though grace doesn’t go back to earth he routinely sends recordings back to earth about all of the additional research he has done,
And the tapes over time show him getting progressively older over time,
he shows them the beach or “human enclosure” marvelling at the technology that makes it possible for him to live on the planet,
Nerding out over all the new bacterium that have adapted to this planets environment and staking naming rights because he “saved the planet and all”
Sending videos of his classes with all the pebbles
Grace getting all excited at the camera because he’s able to document how exactly the gravity of the planet is causing his joints to deteriorate faster than they should have, as well as how the gravity is affecting his other systems (at least that’s what Armando says)
Also him picking up guitar or something because he can’t really walk around anymore or just is really bored, imagine a recording of an older him just singing, I’m thinking ‘spin the wheel’ from arcane (pretend arcane doesn’t exist in universe or grace is just a huge arcane fan)
And a final shitty recording of the eridians trying to use the camera but not quite sure how to use it, Rylands funeral recording makes it to earth
Rocky or Adrian figures out how to use the camera properly, the recordings continue for up to a hundred more years
Edit: another small idea, earth sends things to grace, he complains about not having access to potatoes or some type of clothing or something and 13-15 years later a small shuttle lands on tau ceti, its full of a bunch of graces old things and foodstuffs that increases the food he has available
maybe (if you wanna get poetic/ fanfic-esk) recordings of his old students (so much older, when did they get that tall?) thanking him,
his fellow coworkers from the school making a small video of what has changed around the school,
work colleagues from the project apologising for what they had to do (jumbo sized bag of skittles and twizzlers included)
