Ah. I could have sworn that your defiance should be more than 11. Then your will NOT be broken and you can move around the prison. I think (it has been awhile) you can find something to make a weapon. BEWARE: (this I do remember) You will lose -1 defiance each time you ask for food. IF the weapon is ready, another encounter with those mercs, but you can kill both of them.
I tried several times with Defiance < 10, < 9, 8..., > 10, > 10, 11... (I started from Def 26 and Dep 46) while changing Depravity in the same way, and so on. I found the spoon and prepared it to pierce the eye of the guard behind and cut the throat of the other in front. But either Claire gets pregnant and game over, or she breaks free from the cell by killing the two fuckhead assholes without getting pregnant.
all of whom involve potential pregnancy without game overs.
Are you sure about that? But without going any further, were you able to get her pregnant, or are you just speculating while reciting the walkthrough?
