- Simon: Did you do anything today?
- River Tam: Played with Kaylee. The sun came out, and I walked on my feet and heard with my ears. I hate the bits, the bits that stay down and I work, I f-function like I'm a girl. I hate it because I know it'll go away! The sun grows dark and chaos has come again. It's... fluids. What am I?
- Simon: You are my beautiful sister.
- River Tam: I-I threw up on your bed.
- Simon: Yep. Definitely my sister.
