Fathers and Sons

Danny's son Sean suffers a head injury while riding his bicycle with Erin, Nicky, and Jack. He is taken to the hospital unconscious and the family is told it will take time for him to wake up. The timing couldn't be worse for Danny, as it happens while he's in the midst of investigating a sniper (Paul Anthony Stewart) who is shooting motorists that drive gas guzzlers. His ammunition consists of lead alternatives and he leaves trash from a green market at the crime scene. Danny and Kate track down the head of an environmental movement (Neal Huff), who points the finger at an ex-military man he believes committed the crime. Interspersed within the initial investigation, Danny visits Sean in the hospital and prays to his deceased brother Joe to intervene and help Sean recover. Danny leaves and he and Kate find the accused sniper dead from an apparent suicide. Danny notices the man appeared to have shot himself with his right hand, despite it being a recorded fact that he was left handed. He was hence murdered and Danny comes to the conclusion that the environmental chief set them up. Knowing that his time is up, the environmental chief tries to flee from Danny on foot, but is hit by an SUV (ironically, the same type of car that the sniper would have targeted) and incurs a broken leg, allowing him to be caught. Back at the hospital, Sean wakes up with Danny and Frank nearby. Danny then visits Joe's grave and utters 'Thanks, kiddo.'
