I've always been curious about the necklace she dons after her transformation in the Eyrie after she decided to lie for Littlefinger and not watch him fly through the moon door! The necklace she decides to wear is a bisected circle and then later on in the series it changes to a circle. I have no idea when this change of necklace takes place, but I have always wondered about the significance. If you guys can shed some light on this I'm interested!
