Time for some reality show math. "American Idol" has four finalists left and four weeks of competition before a winner is named May 16.
The Fox singing contest will need two contestants that last week. But how do we get there? The judges didn't use a save this season, and that one-time twist supposedly ended last week.
Perhaps Ryan Seacrest will explain a contingency plan that keeps one of the four women another week. I'm sure fans would like to know as soon as possible, because another twist might infuriate the dwindling audience this season. The two-hour competition starts at 8.
Candice Glover is the favorite in a field with Kree Harrison, Angie Miller and Amber Holcomb. Of course, Fox would never end the show a week early and proclaim Candice the winner. The network needs the ratings in the May sweeps, which start Thursday.
"Duck Dynasty" heads to Hawaii for its third-season finale at 10 on A&E. How will the Robertsons fare in a tropical paradise? It's not going to be pretty, and A&E is serving one hour of vacation highlights.
CBS delivered a rousing tribal council on the last "Survivor." It's highly unlikely that the episode at 8 will be as memorable. But the Three Amigos -- Malcolm, Reynold and Eddie -- will continue to try to outwit and outplay the alliance of six. Reality show math is not in the Three Amigos' favor. "Survivor" names its winner May 12.
Most scripted series are in reruns, because the networks are saving fresh episodes for sweeps. But "Law & Order: Special Victims Unit," at 9 on NBC, has a new installment about a frat-party crime that reveals a history of sexual assault at a college. "Arrow," the best thing to happen to The CW this season, is new at 8.
The broadcast dramas at 10 are all repeats, but "The Americans" is new at 10 on FX. The show, Keri Russell and Matthew Rhys all deserve Emmy consideration for outstanding work. The disguises have been nifty, too, in this spy thriller. The freshman drama delivers its season finale next week.
