[Rusty and Steve have just driven off two men who tried to bushwhack the marshals and young Ricky Valencia]
Marshal Steve Donovan: I think Rusty and I have a pretty good idea who those two men were.
Deputy Marshal Rusty Lee: We do?
Marshal Steve Donovan: Well, sure! We've only talked to a few people since we've been here in town.
Deputy Marshal Rusty Lee: Then the Rowes are behind this thing, huh?
Marshal Steve Donovan: Yeah, it looks that way. There's only one trouble with it.
Deputy Marshal Rusty Lee: What's that?
Marshal Steve Donovan: We gotta prove it.
