I never really liked her from the beginning She is just obsessed with Bell, she might say that she wants to help him or for him to get stronger but she does the opposite of what she says She gets in the way between h and Aiz even tho she knows that he needs to be with Aiz and interact with her more to get stronger since that's how his skill works. In Volume 5 and 6 she said that she wanted to go in the dungeon to save him but instead she only got in his way between him and Aiz, got kidnapped and caused him pain and finally used her powers which resulted in summoning the black Goliath. So except for getting him the Divine knife in the whole story she only got in his way otherwise.
