I guessed I might have caused a confusion already :P Delilah is the dancer and performer that works at the Ivy Star on the afternoons and nights and Yziie is Zenaida's helper that spends her mornings at Seir's shrine and delights in helping the townsfolk on their problems and who is currently with everyone. Abigail most probably already knows both but they are not supposed to be the same person, I must say though that as part of wanting Abigail to accept the 'knife eared folk' Yziie could have already revealed to Abigail as being Delilah herself but of course not as a half elf yet.
