Blue Bloods season 14 may see the return of Jackie Curatola, played by Jennifer Esposito, who left the show in 2012. Season 13 hinted at her return and featured a reunion between Jackie and Danny Reagan. Jennifer Esposito's departure from the show was controversial as she was diagnosed with Celiac disease, which led to conflicts with the production schedule. However, she made a cameo in season 13, and it is possible that she may return in season 14.
