The Deadliest Catch

Rescue Me
10 pm/ET FX
Everybody knows that Tommy Gavin is a little crazy, but too crazy to run into burning buildings? Find out tonight, when he has his FDNY Section 8 review. Meanwhile, Mike goes through with his plan to buy a bar, and a French writer (an attractive young woman, not surprisingly) is wandering around the firehouse, asking the guys to talk to her about 9/11. She gets an earful from Franco, who calls the attacks "an inside job"— a view echoing that of Daniel Sunjata, who plays Franco. —Paul Droesch

Biggest Loser: Couples
8 pm/ET NBC
The makeover episode is here! The seven remaining contestants meet with celebrity stylist Tim Gunn to pick out figure-flattering outfits. Then it's off to the salon, where Tabatha Coffey and Brandon Martinez add the final touches before the players reveal their new looks in front of family and friends. But the glamor and excitement doesn't last long for one contestant, who receives disappointing medical news. —Brie Hearn

90210
9 pm/ET CW
The past meets the present tonight when Tori Spelling reprises the role that made her famous. Donna Martin, all-around good girl and BFF to Kelly Taylor, jets into the zip code for a quick visit. Reality then meets make-believe when self-professed 90210 überfan Diablo Cody (playing herself) offers Donna the opportunity to design a special dress. Meanwhile, West Bev's next generation volunteers with Habitat for Humanity, while Annie and Dixon spend their spring break revisiting Dixon's past. —Rhoda Charles

Dancing with the Stars
9 pm/ET ABC
Tonight Rascal Flatts sing their new hit "Here Comes Goodbye," as well as the Beatles' classic "Revolution." Speaking of classics, the cast of Broadway's revival of "West Side Story" stop by to perform "America." And this jam-packed results show also features a cabaret performance with Carmen Electra. Plus, there's still the little matter of an elimination to get to. One consistent this season has been the variety of contestants popping up in the bottom two. Will that hold true tonight as well? —Jennifer Sankowski

Deadliest Catch
9 pm/ET Discovery
Missing bait sacks make one captain crabby while another skipper feels the pinch of his chewing-tobacco habit as the gritty reality series sets sail again. The fifth-season premiere also features an impromptu fireworks show and a returning deckhand, who heralds the beginning of uncertain times aboard one boat. —Michael Chant
