After a brief catch up, Renko inquires about the Swaztik-Skins. Dalton replies that they had captured their leader, Clancy Reddington last year, but at his indictment for the triple homicide of three black men two months earlier, he pulled off an escape, killing a court officer, two Dallas P.D. officers, and a Texas Ranger in the process, before fleeing the state.

Learning this, Renko asks Dalton to send everything he knows about Reddington. Dalton decides to do one better and sends not just everything about Reddington, his group, and his crimes, but also, Detectives Bianca Diaz and Trey Mathis from his unit to assist in the case.
