Firefly

[Simon enters his and River's room, where River is laying down, looking ill.]

Simon:
Whoa. Mei-mei. How you doin'?

River:
I threw up.

Simon:
Mmm...I'm sorry, it's a side effect. We just have to find the right treatment for you. How do you feel now?

River:
Going. Going back, like apple bits, coming back up. [shakes head] Chaos.

Simon:
But you felt okay this morning?

River:
[smiles wanly] Played with Kaylee. The sun came out, and… I walked on my feet, and… heard with my ears. I ate the bits. The bits did stay down. And I work. I...function like I'm a girl. [sobs] I hate it because I know it'll go away! [sobs] The sun grows dark, and chaos is come again. [sobs] Bits… fluids! [sniffs] What am I?

Simon:
Shh-shh...:[Simon hugs River reassuringly.] You...are my beautiful sister.

River:
I... I threw up on your bed.

Simon:
[Simon winces, then smiles.] Yup. Definitely my sister. [River smiles and chuckles while still crying into Simon's shoulder.]
