[Mattie comes to get Rooster and finds him talking with LaBoeuf]
Mattie Ross: This man wants to take Chaney back to Texas. That's not what I want.
Rooster Cogburn: He wants him caught and punished - so do you.
Mattie Ross: I want Tom Chaney to hang for killing my father. It's little to me how many dogs and senators he killed in Texas.
Rooster Cogburn: You can tell him to his face, you can spit in his eye, you can make him eat sand out of the road, you can shoot him in the foot and I'll hold him for you - but first we gotta catch him.
