Simon: How do you feel now?
River: Going. Going back like apple bits, coming back up. Chaos.
Simon: But you felt okay this morning?
River: [Smiles] Played with Kaylee. The sun came out, and I walked on my feet, and heard with my ears. I ate the bits, the bits that stays down. And I work, I functions like I'm a girl. I hate it, because I know it'll go away. The sun grows dark and chaos has come again. Bits...fluid... what am I?!
Simon: [caressess her] You are my beautiful sister.
River:... I threw up on your bed.
Simon: [beat] Yep... definitely my sister.
