A university professor turns larcenous — and potentially dangerous — in the new episode "The Blood of Romeo," which finds Alex (Priyanka Chopra) and her colleagues pursuing the teacher following the theft of weaponized uranium. Its use appears to be timed to a New York gathering of global leaders. Jessica Hecht guest stars. Jake McLaughlin, Johanna Braddy, Russell Tovey, Alan Powell, Marlee Matlin and Blair Underwood also star.
