Mal: All right, let’s get these crates stowed, I don’t want any tourists stumbling over them.

Kaylee: We’re taking on passengers at Persephone?

Mal: That’s the notion. Could use a little respectability on the way to Boros. Not to mention the money.

Jayne: Pain in the ass.

Kaylee: No, it’s shiny! I like to meet new people, they’ve all got stories!

Jayne: Captain, can you stop her from being cheerful, please?

Mal: I don’t believe there’s a power in the ‘Verse can stop Kaylee from being cheerful. Sometimes you just wanna duct tape her mouth and dump her in the hold for a month.

Kaylee: I love my captain.
