Agree with Glaurung. Nell is usually pretty easy to start a relationship with. You don't need to do the advanced training for it to progress.I respectfully disagree. Been trying to get to 1st base with Nell for like 2 weeks now. It's day 47, and she still won't let me kiss her. I brought her the romance novel. I've revealed all her secrets and done advanced training with her. If I've missed something, I've no idea what. And if I haven't missed anything, like I think, then I need to cheat...
Same questions as he had. What is your charisma stat? Have you solved her small secret yet? Were you honest during the interrogation (like the fairy queen, she is a truthsayer).
Usually it is spend time with her about 3x, on the second time bring her a book - the book used to matter (Romance) but I haven't tested 1.0 enough to know if that still holds true.
