Firefly

[Mal has Jayne locked in the cargo bay airlock, with the door open to the dwindling atmosphere.]

Mal:
You know, I hear tell they used to keelhaul traitors back in the day. I don't have a keel to haul you on, so...

. . .

Jayne:
What're you takin' it so personal for? It ain't like I ratted you out to the feds!

Mal:
Oh, but you did! You turn on any of my crew, you turn on me! But since that's a concept you can't seem to wrap your head around, then you got no place here. [Pause.] You did it to me, Jayne. And that's a fact.

. . .

[Resigned to his fate, Jayne calls Mal on the comm-link one last time.]

Jayne:
What're you gonna tell the others?

Mal:
About what?

Jayne:
'Bout why I'm dead.

Mal:
I hadn't thought about it.

Jayne:
Make something up. Don't tell 'em what I did.

[Mal relents and closes the door.]

Mal:
The next time you decide to stab me in the back, have the guts to do it to my face.

[Mal walks away.]

Jayne:
Can I come in?
