Quantico, starring Priyanka Chopra, scored a last-minute 13-episode third-season renewal from ABC with a new showrunner, and at a lower license fee. The pick-up came less than 24 hours before the network’s upfront presentation last month. Creator/executive producer Josh Safran stepped down as showrunner but will stay on as a consultant for Season 3. A search is underway for his replacement.
