Sister

A female which you share your parents with, they have 2 sides
#1 side,
she's your friend and understands what your going through, helps you when you need it
#2 side,
She's a total bitch who doesn't give a damn about your fucking life, she thinks she has it hard when you have no sister
(#2 is mine -.-)

Sister, being either loving or a bitch

#1
Hey Hun you okay about the break up?
#2 fuck you! Wait why in the hell are you in my room? Is it because your "break up"? FUCK THAT GET THE HELL OUT

Big Sister

A big sister is a little sister that has grown up, and is no longer capable of collecting Adam from corpses. They are in a deep sea diver suit, just like a Big Daddy. They are able to use Plasmids, and have a large needle to take Adam and transfer it into themselves.

Eleanor: If I can survive, I’ll need to become like you. I’ll need to become a big sister.
