Having succeeded in Nettie's persuasion rolls (with the assistance of Shadowheart's Guidance) I managed to avoid her poisoning me with her stick. Instead she gave me some wyvern poison to use if I felt myself transforming. I felt extremely pleased until I realised I was locked in the room and she kept talking about letting the poison do its work. I am sure this is not as designed as I am not poisoned. Only way out is to attack her anyway.
