To all the people freaking out on Rosie becoming an ally, Rosie (don't remember her name that well) does become an ally, but that's really about it. She and Eve will NEVER have a genuine sister relationship and simply more of a "I killed you in my previous life and don't want to die in your hands" type of relationship. She isn't necessarily redeemed, but she's given a chance to save herself. She does not want any involvement in the future with Sir Agnito after. Most of this is what I read on the spoiler threads, but warning, I read this awhile ago and might have said something wrong; however, a majority of it is true. I liked the way the author went about the development of the relationship.
