The main story is depicting how and why the remaining government transformed the whole population of one of their last cities out of desperation to turn the tide of a war that threatens to make them all extinct. When it's all over, these transformed people remain, want their rights, and there's a larger question about should people be allowed to change, should they be allowed to change others, the power imbalance and threatened future of unchanged people who are on average alot weaker.
This character is crushed to learn of the permanence of this change and tearfully makes clear on what her fate will likely be. Increasing the main character's paranoia and hatred against the transformation, the transformed (who can change others easily), and it's far reaching implications.
I am unclear on what that fate for the transgender is beyond a profoundly miserable life. I don't suppose she would ever get used to it, and I'm thinking she would abandon the idea of the most basic of self care. No longer bothering about eating, bathing, working, or doing anything. Essentially forever. But I wonder if that would be over doing it. I am treading on sensitive ground for transgenders and it's an open question on how far I should go with portraying that reaction.
