After the fight where you beat the wench, did you see a menu asking you to Ravish the wench or send her to the interrogation cell? If you didn't see this menu you have probably killed her. Make sure you only use Subdue attacks against Nahir and Angilia if you wish to meet them later.
i got an option to ravish both of them, and in my initial save I did choose to ravish them but they didn't show up, so in my second save I sent them to the cells but they didn't show up then either
