Summary
There is not enough coma slurry onboard to feed Grace once he makes it to Rocky's home planet, and Erid's scientists will only be able to invent human-safe vitamins so fast. But Rocky has been doing Capital R Research on his portable earth thinking machine. Extra calories can be stored as energy in the form of fat cells in humans, and Rocky has tons upon tons of empty calories in his fuel tanks. While it won't do much for the nutrient deficiencies, why not overconsume on purpose to store energy for later?
His human friend is hesitant to agree, but the logic is sound. Gaining some extra weight now isn't going to hurt once the starvation eventually starts.

Summary
At our next Maximizing Rocky Happiness meeting, I pitch my idea to Adrian over a walk down the beach.
They don’t say anything for several seconds after I finish my explanation. Maybe it was a bad idea to share. Finally, Adrian asks, their tone dry, “You want to put Eridian eggs inside squishy human body, question?”

Summary
It's the same word as before, clear as day.
“But… But I can’t.” Grace says blankly. Rocky knows that. Nevermind the xenonite between them, keeping one or both of them from withering in indescribable pain then a swift death, both of their species were wildly incompatible. Trying to merge their biology would be less successful than mixing oil and water.

Summary
“Leaky,” Rocky said. Grace shuddered. His vagina clentched down on nothing. Rocky's interface spread his lips again to follow where his slick gathered and tapped over his hole. “Rocky go inside, question?”
“Uh, I’m not—”
“For science,” Rocky said. He took Grace’s silence for assent and probed back inside. He moved too rough and shoved the finger all the way inside and then pushed up hard, as if trying to push the finger through Grace’s body.
