Blue Bloods season 13 brought back Jackie Curatola (Jennifer Esposito), hinting at a potential return in season 14. Jackie, last seen in season 3 (2012), left the show due to stress, paralleling Esposito’s own departure, driven by her diagnosis of Celiac disease. In season 13, Jackie reappeared as the police chief in Suffolk County, collaborating with Danny Reagan to apprehend Dr. Walker. The season finale left room for a possible return, especially to address the unresolved storyline. Despite the likelihood of a regular comeback being uncertain, Jackie’s return in season 14 could enhance the show’s premiere, adding intrigue and continuity to Blue Bloods.
