This was excellent! Loved it to bits. Thanks so much for sharing.

The dynamics between the Js were interesting and new.

Really enjoyed the philosophical questions and dilemmas you brought out in the story.
Like: How much of a person can you replace before it stops being that person anymore?
And with the cyborg stuff: When replacing human parts with mechanical ones when does one stop being human and become a machine?
Also how far can you go in the name of science?

Great work. Really well thought of and very impressive with all the medical descriptions!
