I loved how you introduced the a/b/o meme perfectly in the first couple of paragraphs. I did, when you first started sharing this at Word Wars, read the page about the a/b/o trope that you linked to at the top, but your own introduction laid it out without laying it out too specifically--just enough to make the reader go "hmmmm....now THAT'S interesting." Especially making Jim an omega.
Your scenes of introduction between Jim and Bones are gritty and compelling, and make me immediately want to put them together, to the dismay of both of them.
So glad to see this posted!
