The Host

Scully: Mind if I sit here?
Mulder: I have to warn you, I'm having violent impulses.
Scully: I'm armed so I'll take my chances.

(Mulder on leaving the FBI.)
Mulder: It's hard to grin and bare it when they ask you to 
        bend over and grab your ankles.

(Mulder looks at fluke.)
Mulder: How big can this thing get?
Scully: Sorry, for a second there it felt like old times.

Scully: This was living inside the body. Apparently, it 
        had attached itself to the bile duct and was feeding 
        off the liver.
Mulder: LOVE-ly.
Scully: Believe it or not, something like 40 million people 
        are infected worldwide.
Mulder: This isn't where you tell me some terrible story 
        about sushi, is it?
Scully: Maybe you'd rather hear what you can catch from a 
        nice rare steak.
Mulder: So....what?  The murder weapon was a nice top 
        sirloin?

Mulder: Don't you get it, Scully? They don't want us 
        working together, and right now that's the only 
        reason I can think of to stay.
