Its absolutely pivotal for the theme of the plot of part2 that the protagonist is around 25-26 in act2, I can't go into explaining it because its a spaghetti mess, but its one of those things that I have to work around
Its a science fiction story and there's a lot of forms of life-extension that are used, which can explain how they'd live long enough to see the protagonist emerge from oblivion
I'm really sorry, it is kind of a strange setting, and all humans are sterilized, so no kids. The only way to get one is to basically buy one from the government(s), and the only offer certain DNA Genome-types (humans reproduce completely through cloning and alter themselves with cosmetic surgery later if they want to look more unique), she meets other characters later that I believe could be used to help explain the parts of the world that have changed since she was imprisoned however
The protag's sibling, best friend, and SO from before all survive, for some reason the number 50 years just seems to keep yelling at me
Honestly this is a great conversation, I had a thought just a minute ago that gave me goosebumps because I liked it so much, I'm writing down a bunch of notes!
My real challenge is adding the loss, but I had another theme pop into my head:
Warmongering as a theme. If I push back the date that the protagonist was imprisoned, it would overlap with a war. The protag's homeworld was infamous for being very warlike (like Sparta in space), and when she emerges into a world in peacetime, and makes war on the antagonists, it could be argued by the opposition that the protag just "doesn't know how to live in a world without war" and are accused of "making a war so that you know how to live"
And it could be up to the reader to decide if this is true?
But it leads back to loss. I want the protag to experience a powerful and damning loss before imprisonment, and they basically brood within the rage and hatred of that loss for the entirety of their detainment...maybe some kind of flashback of some kind?
Perhaps an enemy that uses some kind of technology to render the protag to relive their memories, and thus use the trauma to weaken them enough to kill them?
Something else just occured to me...instead of imprisonment, I'm feeling that if the protagonist could present enough of a threat to the antagonist, the antagonist should really have gone all out to kill them, not imprison them. So instead of imprisonment, some other kind of extreme survival situation, where they SHOULD be dead, but survive by indomitable will and perserverence
