They have gradually begun learning about each other, but most of all the language.

The tunnel is completed. Divided halfway by a wall made of the xenonite. We finally see what Eridians look like: rock like spiders with 5 arms/legs and no face. Each arm has 3 fingers. They use a base number of 6. They seemingly have a 5 hour day, but most surprising of all is that they seemingly use sound waves to "see".

Chips away a piece of the hull and throws it over to the Eridians who plan to build a tunnel between the two ships. Like their ship movements, the robot copies Dr. Grace's wave from last time. Seemingly continuing to wave as it has no prompt to stop, so Ryland walks back inside. Actual food on Day 10 of his post-coma trip, a room temperature burito.

Whilst viewing the Petrova line, a huge cluster of IR light flashes. A large cluster of Astrophage. However after it stops emitting light, it blocks the Petrova line on the screen. Turning off the filter reveals it as an object, another spacecraft. Alien life. Next a cylinder object is flung slowly at Project Hail Mary. The objects inside the cylinder state they are from 40 Eridian system.

It's taken 4 years for Dr Grace to reach Tau Centi. Of which he has memory where a bankrupt Thailand medical company study found that there is a coma-brain-fog resistant gene thought in the "junk DNA" of humans and apes that will allow medically induced comatose to be use on the astronauts to prevent them from resultant infighting studied by the Russians.

Works out Astrophage react to the carbon light emitted by Venus and the Sun. Accidentally discovers the polar carbon IR light frequencies control how they reproduce. Goes on a long fighter jet-aircraft carrier-helicopter-more fighter jets-hopping journey to a Chinese aircraft carrier housing many of the other top scientists working on Astrophage. Asked if they can replicate reproduction on mass scale for use as fuel.
