Returns: Wednesday, April 23, at 10 pm/ET (NBC) Number of new episodes: 5

Where we left off: The revitalized show found its footing thanks to new casting (Jeremy Sisto as Det. Cyrus Lupo and Linus Roache as chief ADA Michael Cutter). What's next: The first episode will be the last for Jesse L. Martin's Detective Green. He leaves with a story line that is "troubling and disturbing," exec producer Rene Balcer says. "He may wish he were dead, but he'll be alive." Lupo's new partner? Kevin Bernard ( K-Ville's Anthony Anderson), fresh from internal affairs. Switching roles: When Legal Aid lawyers strike, ADA Connie Rubirosa (Alana De La Garza) represents a poor defendant opposite Cutter. Says Balcer: "They've got an Adam's Rib thing going on."
