[As Serenity begins a fiery dive into atmo, a panel on the bow breaks off, flying over the cockpit's viewport]
Mal: What was that?
Wash: Did you see that?
Mal: Was that the primary buffer panel?
Wash: It did seem to resemble?
Mal: Did the primary buffer panel just fall off my gorram ship for no apparent reason?
[Serenity shudders.]
Wash: Looks like.
Mal: I thought Kaylee just checked the entry couplings. I have a very clear memory of it!
Wash: Yeah well, if she doesn't give us some extra flow from the engine room to offset the burn-through, this landing is going to get pretty interesting.
Mal: Define interesting!
Wash: [deadpan] "Oh god, oh god, we're all gonna die"?
Mal: [on the ship intercom] This is the captain, we have a lil' problem with our entry sequence, so we may experience some slight?turbulence, and then?explode. [to Wash] Can you shave the vector?
Wash: I'm doing it! It's not enough.
Mal: Just get us on the ground!
Wash: That part will happen pretty definitely.
