   Summary

   Ryland Grace expected a lot of things to change when he decided to go back to Blip-A and save Rocky, but he had no idea things would get this complicated. Namely, this emotionally involved.
   --
   Ryland Grace will starve on his way to Erid without figuring out a new food source. In this universe, Rocky offers to help create a food Ryland can eat during their journey on the Hail Mary together by hybridizing Ryland's DNA with food from his planet. As a result, Ryland begins taking on... different traits. Traits that make it possible for him and Rocky (and eventually, Adrian) to get closer than any of them ever thought they would be while the three of them start a life together on Erid.
   --
   To simplify, Ryland Grace becomes the mate (and eventual pebble incubator) to Rocky and Adrian.
