The show "Blue Bloods" has been on the air since 2010 and has kept the story of the Reagan family interesting. Erin is running for District Attorney, but the show has also developed characters' personal lives. One notable development is the relationship between Jamie and Eddie, who went from police partners to getting engaged and married. However, the show's showrunner says that having a child would sideline Eddie and restrict storytelling. While it may happen eventually, for now, the focus is on other storylines, like getting Danny and Maria together.
