Elsewhere, Simon wanders into his quarters to see River sitting there, looking a little peaked. He rushes over to her and covers her with a blanket, asking her what's wrong. She says she threw up. Simon explains that it's a side effect of the drugs. He asks how she's doing. River rambles on about "going back" and apple bits and chaos, indicating, I think, that she's regressing back to her earlier mental state. Simon points out that she was feeling better earlier. She tells him about playing with Kaylee and says things like "the sun came out" and "[she] heard with [her] own ears" to indicate that she was feeling normal. Well, normal-ish. She starts crying and insists to Simon that she hates it when she "function[s] like [she's] a girl," because she knows it's only temporary and she'll go back to being batshit loopy. She demands, "What am I?" Simon hugs her and responds, "You are my beautiful sister." River says, "I threw up on your bed." Simon repeats, "Yep. Definitely my sister." Awwww. Wait till you see what she did on your vests.
Book reads his -- God, I'm not going to say it. He looks up somewhere off-camera and points out that Inara had requested privacy. We cut to see that he's sitting in a common area, and nearby, Kaylee and Jayne are peeking out into the cargo bay from a catwalk. Kaylee wants to see Inara's client and wonders if he will bring her gifts or flowers. I can imagine Kaylee watching The Bachelor and being all, "I can't believe Aaron didn't pick Gwen! They were perfect for each other!" Jayne is eating an apple, which is still impaled on his knife. Jayne is essentially the walking definition of "lascivious." Ooh, he's human Greebo! Okay, a lot of you aren't going to get that, but those of you who read Terry Pratchett will agree -- Jayne is human Greebo.
