Summary
Analysis
Ryland contemplates the risks of working with the Eridians, debating whether their knowledge of Astrophage outweighs the dangers of trusting an unknown species. He recognizes that ignoring them isn’t an option; if they have even the smallest piece of useful information, he has to take the chance. He also tries to think from their perspective: if they want to build a tunnel connecting their ship to his, they need to know what his hull is made of. Realizing they might need a sample, he decides to provide one himself.
Until now, Ryland has solved problems alone, relying only on Earth-based knowledge. But the possibility that the Eridians hold vital information forces him to move beyond caution. The decision to offer a sample of his hull represents an act of trust without words—a physical gesture to build common ground. Still, he has no idea what will come from abandoning caution in this way.

Equipping himself with EVA tools, Ryland exits the ship and carefully chisels out a piece of the hull. His first attempt nearly results in the sample drifting off into space, but he catches it just in time. He then throws the hull piece toward Blip-A, hoping they understand its significance. To his surprise, the ship’s robotic arm extends, catches the sample with precision, and then waves at him. Ryland waves back before returning inside to wait for their response.
The EVA scene shows Ryland’s continued balance between competence and vulnerability. His mistake nearly costs him the hull sample, reminding him that even small tasks in space carry serious risk. But his recovery and the Eridians’ response shift the tone from tension to warmth. The mutual waving, though simple, suggests the first spark of camaraderie.
Themes
As time passes with no immediate reaction from the Eridians, Ryland busies himself adjusting the ship’s proximity alert settings and retrieving a meal. He reheats a pre-packaged burrito in the sample furnace, humorously noting how he could cook it instantly using the ship’s spin drives if he didn’t mind losing an arm in the process. As he eats, a flashback surfaces, taking him back to a meeting with Dimitri and Stratt, where Dimitri demonstrated the Astrophage-powered spin drive. The experiment produced an enormous burst of energy, melting a massive metal plate in an instant. Ryland had been stunned by the power of Astrophage propulsion, making him realize the danger of even a small sample.

The proximity alert finally sounds, pulling Ryland back to the present. Blip-A is moving closer—not sending another cylinder but bringing the entire ship toward him. As he watches on the external cameras, he notices a newly attached cylindrical tunnel on the alien ship’s hull. The Eridians extend robotic arms toward Hail Mary’s airlock, using an unknown adhesive to secure their end of the tunnel. The ship groans under the unexpected force, but the connection holds. Once in place, the Eridians pressurize the tunnel, though Ryland worries about potential hazards: what if their air corrodes his ship? Or what if human air is deadly to them?

Determined to proceed, Ryland enters the airlock and depressurizes it before opening the outer door. The tunnel is now sealed between both ships, but the Eridians have placed a hexagonal panel at the midpoint, forming a barrier between them. He realizes they’re being cautious, just as he is. Taking a leap of faith, he manually introduces air from Hail Mary into his section of the tunnel. The pressure equalizes, and he steps out of his suit, immediately feeling the heat and strong ammonia smell in the air. Before he can investigate further, three deliberate knocks come from the other side.
