Blue Bloods” character Erin Reagan (Bridget Moynahan) has proven herself to not only be brilliant but also incredibly strong. Growing up in the Reagan household will make any person, to be honest. Her entire life was spent as the lone sister surrounded by brothers, with only her mother in the house amidst a host of Reagan men. As an adult, she stands out among her grandfather, Henry (Len Cariou), her father, Frank (Tom Selleck), and her brothers, Danny and Jamie (Donnie Wahlberg and Will Estes, respectively).

As an adult, Erin took a different path from her brothers. While they went on to become members of the NYPD, she spent her days as a prosecuting attorney. But with her strict adherence to the letter of the law, she sometimes pushes back on the police to get more evidence or build a better case. This puts her at odds with her family, sometimes even making it feel like she is actually a defense attorney.

Due to her passionate focus on what is right and wrong, you would be forgiven to think she was a goody-two-shoes as a child. But, in reality, throughout the series, she is revealed to have been the more rebelious of the Reagan clan.Because of her rich history and constant conflict with her police family, there are plenty of great moments for her, but one episode feels above the rest for Erin Reagan.
