In 2010, the inaugural episode of CBS’ family police drama hit the screens, introducing viewers to the iconic Reagan family, including Tom Selleck’s Frank Reagan and Donnie Wahlberg’s Danny Reagan. The episode also briefly introduced Erin Reagan-Boyle’s (Bridget Moynahan) daughter Nicky, portrayed as a sensitive child unafraid to voice her opinions. She candidly informed her uncle Danny (Donnie Wahlberg) that her mum was upset with their grandfather Henry Reagan (Len Cariou) for taking his side over hers.
Henry later quipped that kidnappers would “throw Nicky back in five minutes”, causing the young girl to storm off. Child actress Marlene Lawston had previously appeared in several other projects before Blue Bloods, including Flightplan, Law and Order, and Dan In Real Life. During this time, she worked alongside some big names, including Jodie Foster in Flightplan and Steve Carell in Dan In Real Life. However, Blue Bloods marked Lawston’s final onscreen role, ending her acting career. From the fourth episode onwards, the character of Nicky was portrayed by Sami Gayle.
Having stepped away from the limelight, Lawston has been diligently pursuing a completely different career path, studying at the University of Rochester’s School of Medicine and Dentistry. She had previously studied at Colgate University and, as Looper reports, in 2020 she was awarded the prestigious NIH Oxford-Cambridge Scholarship, enabling her to pursue both her Master’s degree and PhD. Colgate University’s official website provides more insight, revealing that her research focuses on genetic disorders and “uses stem cell models and genetic testing from families with the duplication/deletion disorders to better understand the disorders at a cellular level”.
Discussing her drive for her research, Lawston disclosed: “I was always interested in research that would impact health care.” The university’s site notes that her own “health issues as a child” led her to “develop an appreciation for the medical system”.
We all remember her—the vibrant, ambitious Nicky Reagan-Boyle from Blue Bloods, played by Sami Gayle. She was a staple of the Reagan family dinners and a fan favorite from the show’s early seasons. But then, almost out of nowhere, she was gone. Replaced. And fans were left wondering: What happened to Nicky?
Let’s take a deep dive into why the original Nicky left Blue Bloods and what shocking direction her career has taken since.
Who Was the Original Nicky on Blue Bloods?
