* Ugly Betty (10:01/9:01c ABC)
The show's recent resolutions - Hilda's wedding, Justin's coming out and Betty saying good-bye to Gio and Henry (for now) - have been satisfying and well-done, but they were also a wistful reminder that the end was near. This series finale concludes a winsome, if at times uneven, four-season run, and hopefully ties up a few more loose ends, such as who, if anyone, was hit by Tyler's drunken misfire, whether Spencer is Amanda's father and the odds that Betty will start a new life in London.
* Human Target (8/7c Fox)
Ever since we met this most recent incarnation of Christopher Chance, we've heard tidbits about and seen glimpses of his past. And thanks to flashbacks from six years ago in tonight's first-season finale, we'll find out more about his old boss (Armand Assante), the oft-mentioned Katherine (Amy Acker) and how he teamed up with Winston and Guerrero. And if that's not enough, septuagenarian Lee Majors also guest stars as another Christopher Chance, so it seems the current one isn't the first to do what he does.
* American Idol (9/8c Fox)
It's so last week, but we really should review the sonic dramas in last Wednesday's barn burner. Michael Lynche, he of the hulking physique and golden pipes, was unanimously saved from elimination by the one-time-only "judges' save," his tenderly precise take on Kate Bush's "This Woman's Work" doing the trick. This changed the whole dimension for this week. Nine singers performed last night, not eight as first designed, and two contestants will be ousted in tonight's results shindig. Glam rocker and Season 8 runner-up Adam Lambert - who served as mentor last night - performs "Whataya Want From Me."
* CSI: NY (10/9c CBS)
Fans of Ozzy Osbourne are in for a treat as "Let Me Hear You Scream," the rocker's first single from his summer 2010 album Scream, makes its premiere in this episode. And scream is what Hawkes wants to do when he gets caught up in a prison riot while visiting a Pennsylvania penitentiary to honor a death-row inmate's final request. His colleagues back in New York then must bust Hawkes out of the high-level security facility before the inmates realize he is a cop.
* When Families Grieve (8/7c PBS)
