Lost
9/8c ABC
Sadly, we must scratch Sayid, Sun and Jin from the list of candidates to succeed Jacob. That leaves Jack, Sawyer and Hurley, who, along with Kate, are back on the beach and awaiting the final battle with the Locke Monster, whose motives become clear (or at least as clear as things get on Lost) in this episode. Speaking of battles, expect background on the epochal Jacob-Man in Black tilt. And Allison Janney becomes part of the Lost universe, playing a character listed as "Woman." — Paul Droesch

The Good Wife

Alicia or Cary? The two lawyers have been vying for the firm's single junior-associate position all season, and now Will and Diane make their decision on who stays and who goes. But that's not all that's on Alicia's mind. She gets involved in a divorce case as she deals with the shocking news that real-estate developer Gerald Kozko, who tried to obtain damning evidence to use against Peter, committed suicide shortly after she refused his plea for help. — Tim Holland

Justified

10/9c FX
Now that Boyd Crowder is out of prison, Raylan is in the Marshal's office doghouse, and he's taking some involuntary vacation this week. But the show isn't, and Raylan isn't exactly lolling on a beach: He's trying to extricate his ex-wife Winona's new husband, Gary (William Ragsdale), a not-particularly-successful real-estate developer, from a potentially fatal hole he has dug himself into with two of his "investors." Jere Burns plays one of them, and Malik Yoba guest stars as Gary's friend Toby, an NFL alum. — Paul Droesch

30 for 30

8/7c ESPN
As a treat to Oakland Raiders fans who've endured seven straight seasons as an NFL laughingstock, actor-writer-director Ice Cube chronicles a more memorable chapter in team history: the Los Angeles years (1982-94). In "Straight Outta L.A.," the former N.W.A. rap artist examines the cultural connection that instantly developed between renegade owner Al Davis' Raiders and the African-American and Hispanic population of the team's new city. In the wake of the woeful JaMarcus Russell era, the documentary footage of Marcus Allen and Co. should trigger fond memories, even for viewers with no affinity for the Silver & Black. — Roger Leister

A new season of the news magazine gets underway with a look at how U.S. companies are involved in the search for carbon offsets in the Amazon while Congress contemplates legislation to make them pay for the pollution they cause. Other stories examine the long-term repercussions of a 2008 immigration raid at an Iowa meatpacking plant and a new approach to the threat of cross-species diseases. — Jeff Gemmill
