"Blue Bloods" has established the idea of family through its plots and themes. The Reagan family, comprised of law enforcement officers, comes together for Sunday dinners. These dinners often carry the moral lesson of the episode, but can be challenging to film. The cast has a running gag where they snore if someone makes a mistake during a dinner scene. Actress Vanessa Ray, who plays Jamie's wife on the show, was initially intimidated by the iconic dinner scenes. The dinners scenes can take hours to shoot and involve repetitive eating or pretending to eat.
