  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.
