Actually, I am thinking of giving Blake a chance to eventually return to where he started, however:
- It will take the rest of the game, so don't expect him to switch back to masculinity (or the closest thing to masculinity that he has) halfway through, or after some important decision, because you'll have to make these decisions until the game ends.
- It won't happen just because he wants to, as he's much more comfortable in feminine image. It will likely need some environmental factors (say, he ends up being alone somewhere in the slums. Looking like a woman will lead to him getting raped and possibly killed), or maybe brainwashing by some other characters.
Basically, it's gonna be one of the bad endings, where Blake is forced to be the person he doesn't want to be, and doesn't have enough strength to resist that. And the very first step towards this ending you'll be able to make in the next update.
