Blow Up

S1, E4: Once Kenny and Luther have made the pairings, they set the duos to work in a bomb-sniffing exercise that features live gunfire and explosions. One of the dogs, who, like the rest in this class, has already served time in Afghanistan or Iraq, shows signs of resistance at the first sound of explosions, and it's up to the guys from VLK to determine if she is capable of seeing combat again. Danny is dealing with a different kind of personnel problem: K.C., the boss's son, is perpetually showing up late and missing work. His young age and lack of real-life experience make it difficult for him to earn the respect he thinks he deserves: not only from overzealous trainees but also from his own dad.
