Well, surprised and angry work.
And also just "being". The right costume and suggestive setting and you fit in almost any category. For example....
(Actually you all look good in these suits. Might unfold a scene something like this....)
"Nice work, fellas. So, it's the infamous Canyon and Fatima, huh? Accomplices of Pitfall Harry's gang."
"We ain't part of no Pitfall Harry gang, mister. Let me ask you something. Do you and that goon squad of feds always snatch a lady off the street when she's minding her own business whenever you get the hankering?"
"Hankering nothing. She'd a gunned us down if we didn't put on the charm to get that info out of her. Don't let her fool ya."
"I don't know what you're talking about."
"Yeah? My apologies. Guess we had it figured all wrong. Thought you two were Canyon and Fatima. Two dames mixed up with Pitfall Harry - rumored to be branching out into his own racketeering and bank robbery business."
"Couldn't tell ya, mister. What's it to you? Way I hear it this whole district is on the payroll."
"Where'd a nice girl like you get an idea like that? Let's see. Pitfall. Pitfall. Worked under Luceno Mustodini before going into business for himself. Still no idea?"
"Not a clue. What say we get going now? Your fed boys gonna give us a ride back or do we get ta pay cab fare for this visit, too?"
"Then you wouldn't mind a few questions from Mr. Mustodini?"
"What? Here? W...wait a -"
"- Canyon and Fatima. It's a big mess ain't it?...."
"....Don't worry about that cab ride or any of this mess. We'll get you out of the picture. There's a driver waitin' outside for ya. You remember Johnny? He takes real good care of all my legal troubles and I want him to do the same for you two."
"Detective. You ain't gonna let us go in that car?"
"Well, bein' that you and her ain't the girls we're lookin' for, there's no need to worry. Those two would need serious protection. Sorry for the confusion." ...............
