Ep 19. Model Behavior

In Blue Bloods season 1 episode 19, entitled "Model Behavior," tensions run high in the Reagan family after a high-profile fashion designer is found murdered in a busy street in the heart of Manhattan. Tensions are further heightened when Erin (Bridget Moynahan) realizes that her ex-husband Jack (Peter Hermann) is defending the prime suspect, a model who was seen fleeing the scene of the crime.

Danny (Donnie Wahlberg) and Jackie (Jennifer Esposito) are assigned to investigate the murder of the fashion designer, who happens to be a close friend of Frank's (Tom Selleck) personal tailor. The investigation quickly leads them to a group of models, all of whom seem to have motive, but no one with an obvious opportunity.

Meanwhile, Jamie (Will Estes) is struggling with his feelings for his partner, Renzulli's (Nick Turturro) daughter, after they share a kiss following a night of drinking. Despite his growing affection for her, Jamie is hesitant to pursue anything more out of respect for Renzulli and his family.

As the investigation intensifies, Erin finds herself in an increasingly difficult position when Jack begins to suspect that the model he is defending may actually be guilty. With her family and professional life colliding, Erin must navigate the tumultuous waters of the justice system and confront her feelings for Jack once and for all.

Throughout the episode, tensions rise and family bonds are tested as the Reagans work to solve the murder of a high-profile fashion designer. With the spotlight shining bright on both the police department and the fashion industry, everyone is left wondering who will come out on top in the end.
