said.
âBuilt from the flesh of the dead,â Cainen said.
âFrom her genes,â Sagan said. âNot her flesh.â
âGenes build the flesh, Lieutenant. Genes dream the flesh, wherein the soul resides,â Cainen said.
âNow youâre a poet,â Sagan said.
âIâm quoting,â Cainen said. âOne of our philosophers. Who was also a scientist. You wouldnât know her. May I ask how old you are?â
âIâm seven, almost eight,â Sagan said. âAbout four and a half of your hked .â
âSo young,â Cainen said. âRraey of your age have barely started their educations. Iâm more than ten times your age, Lieutenant.â
âAnd yet, here we both are,â Sagan said.
âHere we are,â Cainen agreed. âI wish we had met under other circumstances, Lieutenant. I would very much like to study you.â
âI donât know how to respond to that,â Sagan said. ââThank youâ doesnât seem appropriate, considering what being studied by you would probably mean.â
âYou could be kept alive,â Cainen said.
âOh, joy,â Sagan said. âBut you might get your wish, after a fashion. You must know by now that you are a prisonerâfor real this time, and you will be for the rest of your life.â
âI figured that out when you started telling me things I could report back to my government,â Cainen said. âLike the rock trick. Although I assumed you were going to kill me.â
âWe humans are a pragmatic people, Administrator Cainen,â Sagan said. âYou have knowledge we can use, and if you were willing to be cooperative, thereâs no reason you couldnât continue your study of human genetics and brains. Just for us instead of for the Rraey.â
âAll I would have to do is betray my people,â Cainen said.
âThere is that,â Sagan allowed.
âI think I would rather die first,â Cainen said.
âWith all due respect, Administrator, if you truly believed that, you probably wouldnât have shot that Eneshan who was trying to kill you earlier today,â Sagan said. âI think you want to live.â
âYou may be right,â Cainen said. âBut whether you are right or not, child, I am done talking to you now. Iâve told you everything Iâm going to tell you of my own free will.â
Sagan smiled at Cainen. âAdministrator, do you know what humans and Rraey have in common?â
âWe have a number of things in common,â Cainen said. âPick one.â
âGenetics,â Sagan said. âI donât need to tell you that human genetic sequencing and Rraey genetic sequencing are substantially different in the details. But on the macro level we share certain similarities, including the fact that we receive one set of genes from one parent and the other from the other. Two-parent sexual reproduction.â
âStandard sexual reproduction among sexually reproducing species,â Cainen said. âSome species need three or even four parents, but not many. Itâs too inefficient.â
âNo doubt,â Sagan said. âAdministrator, have you heard of Fronigâs Syndrome?â
âItâs a rare genetic disease among the Rraey,â Cainen said. âVery rare.â
âFrom what I understand of it, the disease is caused because of deficiencies in two unrelated gene sets,â Sagan said. âOne gene set regulates the development of nerve cells, and specifically of an electrically-insulating sheath around them. The second gene set regulates the organ that produces the Rraey analog for what humans call lymph. It does some of the same things, and does other things differently. In humans lymph is somewhat electrically conductive, but in the Rraey this liquid is electrically insulating. From what we know of Rraey physiology this electrically insulating
