New Rules

Soon after Frank awards Deputy Chief Donald Kent (Dennis Haysbert), commander of the NYPD gang division, with his second star, Kent and his wife are shot and killed in a likely gang hit. Frank personally assigns Danny to the case, but impresses upon his son that everything must be done by the book. Danny believes he can get information from Hector, who witnessed the hit and is in the hospital with a stray bullet wound, but Hector fears the gangs and doesn't want to cause any trouble. Danny also finds evidence that Warrior Kings gang leader Mario Hunt was in the area where the hit took place and he brings him in, but Erin frustrates Danny by saying there is no direct evidence to hold Hunt. Meanwhile, Jamie encounters Curtis, a young man who works as an orderly at Linda's hospital, hanging around an area known for Warrior Kings activity. Curtis assures Jamie he is just passing through, but Curtis' mother, a nurse, confides in Linda that she is afraid that Curtis is being recruited into the gang. Danny finally gets information from Hector that Hunt ordered the hit, but as he had to let Hunt go, he is now in hiding. Danny and Maria meet with Hunt's old boss, Clinton Wallace, who is serving a life sentence in Rikers. While the boss won't give up where Hunt may be hiding, he does hint to Danny and Maria that their witness may be in trouble. As Danny and Maria race back to the hospital, it appears they will be too late. Curtis wheels a cart into Hector's room and pulls a gun from it. Linda is treating Hector, and she instinctively steps in front to protect her patient. As the screen goes black, several gunshots ring out.
