you and your mother where now moving in to your new home with your step mother and sister. most of your stuff was now in the new house, and you where just bring the last few bits and pieces in, as you neared the door your new step mother, and her daughter who you hadn't met yet came out to greet you " hello, you must be Nat right? I'm Ellie, I guess I'm your step mother, and this is my daughter Rose" your new step mother tells you as you approach " need a hand at all?" she asks, seeming nice enough
