Sicario 2 'Day Of The Soldado'

Kill them all scene, when they arrive by helicopter to avenge the murder of Alejandro, what does Steve say to matt as he loads the girl into the chopper, on subtitles it says 'she said spotless'??? If that is the case who is he referring too??? Any help?

He's referring to Cynthia Foards, the character Catherine Keener played. She was the go-between and the buffer who took her marching orders from Secretary of Defense James Riley (Matthew Modine) and passed them on to Matt Graver (Josh Brolin) and his men.
