Rox and Ethan head out to a road rage accident which took out two cars and a motorcycle. The first victims blame the motorcyclist, but it becomes clear that there's more to the story. The older daughter of the first family is clearly uncomfortable around her step father, and after he gets into a physical fight with the motorcyclist in the ER, she comes clean to Ethan that he was actually the one to cause the accident. The wife seems aware of her husbands temper but has a bit of a "stand by you man" mentality, and attributes her older girl's attitude towards him to a difficult divorce. After the man in the other vehicle dies during surgery, the daughter, Danica, stands up to her step father and tells him that she doesn't want him to come home with them. He becomes enraged and calls her a little bitch, sparking her mother to finally stand up for her. She corroborates the daughters story and tells her husband that he'll be going to jail.
The wife of the victim in the second car faints after she hears her husband is in surgery. She reveals to Jesse and Ariel that she and her husband were in counseling and expresses regret that their last conversation was a fight and that she never got to apologize or say good-bye. She's bereft when she finds out her husband died, but Jesse is able to bring her back with some good news -- she's six weeks pregnant.
