I briefly got weirdly stuck with Marina--after I gave her the third book, the next step was blank. When I talked to her, it gave me options like I'd already reached her first level of corruption; "Talk" did nothing, "Proposition" closed the dialog but left her on screen (cleared her by opening and closing Memories), and "Powers" seemed to work normally--I had a Red Soul I used to learn Pleasure Craving, since I got all the other level 1 citizen corruptions beforehand. After sleeping at the inn and doing a few other scenes, I suddenly got the telepathic message for the final scene. Maybe that was the missing piece, but...shouldn't have been able to use that menu, should I? Regardless, everything seems to be working now.
