TONIGHT'S MUST-SEE

"The Bachelor: Rome," 8 p.m., ABC. Lorenzo Borghese, the American descended from a titled Italian family, is down to two women. In this finale he'll choose one. Jennifer, 24, is a teacher from Pembroke Pines, Fla.; Sadie, 23, is a publicist from Carlsbad, Calif. Borghese will date both one more time, then make his choice.

"Prison Break," 7 p.m., Fox. This is what Fox calls its "fall finale." After tonight, "Prison Break" will spend time on the shelf alongside "Lost" and (after Wednesday) "Jericho." There's a lot to sort out. Michael and Linc have lost their father, their money and Linc's true love. Others have had it worse. T-Bag has lost the same hand twice. Along the way, Michael and Linc have had flickers of hope that they can prove there's a government plot. Sara, who's also on the run, may have an incriminating tape. First, there's the bigger problem: Mahone, the federal agent, has the guys at gunpoint.

OF NOTE

"The Class," 7:30 p.m., CBS. Last week, one of our all-time favorite couples, Richie and Lina broke up. He had split from his wife, but it was too late. Tonight, his luck only gets worse. A bee in his car causes him to crash into a convenience store.

"Heroes," 8 p.m., NBC. The show jumps backward six months to show how things started. Mohinder's father has just reached New York looking for people with special abilities. Far away, Claire becomes a cheerleader, Hiro tries to become a hero and Niki has an unnerving visit from her father.

"American Experience: RFK," 9 p.m., PBS. Here's a rerun from David Grubin, who also profiled Lyndon Johnson, Abraham Lincoln and Franklin and Theodore Roosevelt.
