Actress Sami Gayle, who portrayed Nicky Reagan on “Blue Bloods,” departed from the show after Season 13. Gayle’s exit mirrored her character’s storyline as Nicky left to attend Columbia University. The actress herself was pursuing her degree at the same university. While Gayle’s departure may be temporary, as she could return after completing her studies, fans will have to wait for her potential comeback. In the meantime, Gayle has engaged in other projects, including performances in Broadway’s “Bad Cinderella.” Despite the delay in production due to strikes in Hollywood, “Blue Bloods” is expected to return in early 2024, pending the resolution of the protests.
