Survivor: Heroes vs. Villains
8/7c CBS
Unless Colby, the lone surviving Hero, can win back-to-back immunity challenges tonight and force his way into the final three who will be questioned by and voted upon by the jury members, it appears that a Villain will take home the $1 million top prize. But which one? Parvati and Sandra have won before, but is that enough to not vote for them? Jerri has never won, but her game wasn't the strongest. That leaves Russell. But everyone agrees he is the most diabolical player the game has ever seen, which could leave the Texas oilman coming up just short once again. Following the two-hour season finale, the 20 castaways reunite to learn the winner and discuss their adventure. — Tim Holland

The Simpsons
8/7c Fox
Kelsey Grammer is famous for playing Dr. Frasier Crane in Frasier and Cheers, but his venerable voice turn as Sideshow Bob, Bart Simpson's diabolical (albeit hapless) nemesis in more than a dozen episodes of The Simpsons over 21 seasons, may be his next best known role. Executive producer Al Jean likens him to Wile E. Coyote in the Road Runner cartoons, but Grammer confesses to modeling his characterization after stage actor Ellis Rabb. In this episode, Grammer lends his voice to Bart's new neighbor Walt, whom Bart fears is actually Bob in disguise returning for revenge. — Fred Mitchell

Desperate Housewives
9/8c ABC
If all the worst-case scenarios play out in the sixth-season finale, Lynette, and Angie and Danny will be dead at the hands of Eddie and Patrick, respectively; Susan and Mike will be former Wisterians, exiled by Mike's debts to an apartment in town; and Carlos will know, courtesy of Sam, that it was Andrew Van De Kamp who killed his mother in that Season 1 hit-and-run. Don't expect all that carnage (the show has won Emmys in comedy categories, after all), but do expect resolutions — and, of course, a cliffhanger or two going into next season. — Paul Droesch

The Pacific
9/8c HBO
The war with Japan is finally over on Aug. 15, 1945, but new battles are just beginning for some Marines in the finale of this extraordinary series. Granted, no one is shooting at them anymore, and for Leckie, readjusting to civilian life means lobbying for his old job and courting his neighbor Vera. But it's not so easy for Lena, who meets John Basilone's family for the first time, and Sledge, whose survivor's guilt and night terrors are constant reminders of the horrors he endured. — Joe Friedrich

Celebrity Apprentice
9/8c NBC
Donald Trump gets down to business in Part 1 of the two-part Season 9 finale. One contestant gets the Trump bump and dump following a rude comment, then former Apprentice players Bill Rancic and Joan Rivers conduct punishing interviews with the remaining celebs, after which two more contestants take their Trump lumps and are fired. All that remains are the final two celebrities, who must tap into their business savvy by a creating a new tea product — flavoring it, naming it, promoting it and designing the label. They tea off, but trouble brews and boils over when they tangle over an ingredient. The finale concludes next Sunday. — Dean Maurer

Brothers & Sisters
10:01/9:01c ABC
Somewhat overlooked in recent months during the crashing and burning of Ojai Foods has been the certainty that Rob Lowe is leaving the series, and it appeared his clandestine courtship by shadowy power brokers and their unethical business shenanigans might have something to do with his departure. But in what promises to be an explosive fourth-season finale — if the promo is to be believed — Lowe's Sen. Robert McCallister may be dispatched in a crashing-and-burning of a different kind. — Joe Friedrich

Army Wives
10/9c Lifetime
Before Chase shipped out, Pamela issued an ultimatum to her husband. With his return now looming, it's time for her to face the music — but not before the upcoming USO concert. Needing a distraction from her marriage's pending showdown, Pamela assists Claudia Joy in preparing for Fort Marshall's big event, featuring Wynonna Judd and Five for Fighting. Despite the festivities, the ladies come together to encourage an abused Army wife (Gina Rodriquez) to get help. — Rhoda Charles
