TONIGHT'S MUST-SEE

"Lost" return, 9 p.m., ABC. Three months ago, this terrific show left us in midcrisis. Jack, a surgeon, had been pressured into performing an operation on Ben, the leader of The Others. In the middle of the procedure, he announced he would let Ben die unless Kate and Sawyer were freed. We don't know how that fits into the Hippocratic oath. Or how Jack will get free. Or how Kate and Sawyer will get back to where the survivors are. Producers have promised to get the survivors back together. Tonight's hour also has the backstory of Juliet, an Other played by the superb Elizabeth Mitchell.

"Lost Survivor Guide," 8 p.m., ABC. It's been a long gap between shows so we might need to catch up. Here's a recap hour before the new episode.

OF NOTE

"Friday Night Lights," 7 p.m., NBC. The Panthers should be giddy after winning in the first round of the play-offs. Mac made a racial remark, however, and the team has dissension. Meanwhile, the coach's wife worries about their daughter's friendship with Tyra. Also, the girls prepare for their own game.

"Bones," 7 p.m., Fox. After firing his gun, Booth is ordered to see a psychiatrist. That means Brennan temporarily needs another partner, played by Eddie McClintock. Dr. Wyatt, incidentally, is played by Stephen Fry who linked with Hugh Laurie to create years of brilliant TV comedy in England.

"George Lopez," 7 p.m., ABC. Their daughter has left for college but the house is filling up again. Veronica, George's niece, moves in with her no-account husband (Jason Connery).

"American Idol," 8 p.m., Fox. The auditions have finished now and here's an hour of highlights. Let's hope we'll get to see some strong prospects after the show's recent obsession with sad losers.

"Criminal Minds," 8 p.m., CBS. Here's the second half of the story that started after the Super Bowl. Spencer Reid (Matthew Gray Gubler) is being held captive by a villain (James Van Der Beek).

"The Supreme Court" conclusion, 9 p.m., PBS. Here are two strong stories, showing extremes in court history. First was the Warren court, using the law as a powerful social instrument for civil rights. Then there was the Rehnquist court. William Rehnquist is described as a hard worker with a brilliant legal mind. He brought a conservative tilt, but he was praised as a legal purist, not a mere ideologue.

"CSI: NY," 9 p.m., CBS. Nelly Furtado plays a professional shoplifter who is a suspect in the murder of a security guard.

"Medium," 9 p.m., NBC. When this series opened, we met Kenneth Pash (Arliss Howard), a state police officer who was skeptical about Allison and her visions. Now he's had his own dream of a murder and asks her for help.
