Синя кръв: Playing with Fire

Синопсис

Jamie and Eddie investigate an arson, where Eddie narrowly escapes serious injury. Jamie spots and arrests the juvenile arsonist, but rightly suspects Justin Mathews is being manipulated. Just promoted in the DA's office, Erin is even more reluctant when both Danny and Jamie ask for her help in their investigations. Danny can't prove the murder and decapitation of a Mexican 'dark hand' is the work of drug cartel boss Luis Delgado, whom Danny believes responsible for torching his former house, which Delgado smugly admits under four eyes, even hints his cartel had a hand in the death of Danny's wife Linda. Jamie refuses to stop riding with his fiancee, which isn't against the rules but customarily considered a recipe for trouble, Frank hesitates whether to forbid by discretionary measure. Danny nails Delgado in a drug bust, but openly cuts him loose in front of his crew, so he seems a snitch and is murdered by the following morning. Jamie later reveals to his father that he passed the sergeant's exam at the top of the list and accepts the promotion, with station transfer.
