More details I saw and savored and haven't seen mentioned yet:
- Rocky's clock ticks at the slower almost 2-Earth-second interval that is an Eridian second (yes I counted one Mississippi two Mississippi in the theater, why?).
- Yao and Grace discussing how the unit conversion error was the cause of the explosion, which feels to me like a callback to that one time we crashed a Mars lander because the US part of the team worked in imperial units and the EU part of the team worked in metric and I guess they forgot to cross-check?
- The cut from the aircraft carrier karaoke bar scene to The Moment at Adrian mediated by the lil red-suited scuba guy in the fish tank.
- As Grace is starting to say "She said I had my head in the clouds", the background scenery of the mental health bay turns to a scene of a blue sky with fluffy clouds, camera angle slightly below his head and looking up to that background.
- The bright projector bulb with dust in its beam shown quite deliberately, twice, during the "What is Project Hail Mary" presentation, evoking a star and its Petrova line cloud of astrophage.
- The way the clock-like rhythm to the music and the night-day-night-day changes to the light show the passage of time while Grace is patiently waiting for Rocky to wake up during Taumoeba.
- When Rocky joyfully shakes the filaments in his ship to show Grace how it works, reminiscent of how some spiders shake their webs.
- How both the images and the sounds of Grace's very first memories were visually and auditorially hazy and blurry and fuzzy.
- Grace has his Rocky figurine on his ship's dashboard, and Stratt has her Grace figurine on hers.
- The art behind Stratt in The Betrayal is the two ships. I have seen someone else say this, but I had trouble seeing it at first. But now I do. I'd even say it's clear the Blip-A is the one on viewer's right and the Hail Mary on viewer's left.
- Curiosity killed the cat (Cats t-shirt, cat on San Fran bridge tshirt). (Dunno if this is a thing for real, but it occurred to me so I figured I'd throw it in, because Grace canNOT resist a mysterious person or situation).
- When Rocky's excitedly gabbling away before Grace gets the translator set up, he does the "together" rolling hand motion and points at his Petrova Line tattoo - he's already saying Grace Rocky save stars before they have even a single word in common.
