Cassidy Grimes and Niklaus Mikaelson survived the ritual. When Cassidy finds herself unable to cast even the simplest spell she considers it price paid for Nik's curse being broken. Afraid her hybrid won't want her around if she can't use her magic, she says nothing. When she nearly dies because of it, Nik begins to hunt for answers. When Esther, the Mikaelsons' mother, returns from the grave, she seems to have a soft spot for Cassidy. Elijah, Nik and Cassidy all know it's a lie and wonder at the woman's plan. Because Cassidy shouldn't remember anything from the other side, but she remembers everything. Without her powers, she doesn't stand a change against the Original witch. Or does she?
