- -Tonight, you do

Rachel:
[Louis is lying on the bed, reading a book as Rachel enters the bedroom]
I heard you and Ellie, tonight. Louis Creed:
I figured you might have. I know you don't approve of the subject. Rachel:
I just get... scared. And you know me... [She sits down on the bed] Rachel:
... When I get scared, I get defensive. Louis Creed:
[He puts his book down, and sits up, facing Rachel]
Scared of what? Dying? Rachel:
[Hesitant at first]
My sister, Zelda... Louis Creed:
I know, she died. Spinal Meningitis. Rachel:
She was in the back bedroom like a dirty secret. [the scene cuts to a flashback of a young Rachel entering Zelda's bedroom with Zelda's dinner, as Rachel's voice over continues] Rachel:
My sister died in the back bedroom and that's what she was: a dirty secret. I had to feed her sometimes. I hated it, but I did it. [the scene shows a young Rachel feeding Zelda, with the young Rachel looking grossed out, with Zelda beginning to cough] Rachel:
We wanted to her dead. We wished for her to be dead. It wasn't so that she wouldn't feel anymore pain. It was so that we wouldn't feel any more pain. It was because she was starting to look like this monster. [Cuts back to the present day, with Rachel continuing her story] Rachel:
Even now, I wake up and think, "Is Zelda dead, yet? Is she?" [the scene cuts back to the flackback with a young Rachel standing on the staircase] Rachel:
My parents were gone when she died. Zelda:
[In flashback]
Rachel. [Zelda laughs] Rachel:
[Flashback shows Zelda choking, with a young Rachel trying to assist]
She started to... she started to convulse. And I thought... I thought, "Oh, my God. She's choking. Zelda's choking. And they'll come home and they'll say, 'You hated her, Rachel'", and that was true. They'll say, "You wanted her to be dead", and that was true, too. Then, she died. And I started to scream, I ran out of the house screaming, "Zelda's dead! Zelda's dead! Zelda's dead!" And the neighbors, they came out and they looked. [the scene shows a young Rachel running down the stairs crying, with her neighbors standing in the front door, looking up at her, strangely, as she runs out of the house, where the scene cuts back to present day] Rachel:
And they thought I was crying. But you know something? I think maybe... I was laughing. Louis Creed:
[Louis embraces her in a hug, as she cries]
If you were, I salute you for it. And if I ever needed another reason to not like your Mother and Father, I have one now. You should've never been left alone with her, Rachel, never. Where was a nurse? They actually went out and left an 8-year-old kid in charge of her dying sister, who was probably clinically insane by then. [He gets up] Rachel:
Where you going? Louis Creed:
To get you a valium. Rachel:
But you know I don't take-... Louis Creed:
