Expect all the soapy shenanigans to reach a boiling point tonight in the Season 2 finale of the "Downton Abbey," ceaselessly addictive costume drama.
The two-hour episode has the family gathering to celebrate Christmas and welcome the new year (1920). But not all is bliss as poor Mr. Bates (Brendan Coyle) is on trial for the murder of his wretched ex-wife.
Meanwhile, we continue to wonder if Mary (Michelle Dockery) will throw over Sir Richard (Iain Glen) and pledge her true love to hunky Matthew (Dan Stevens). Who knows where that plot line will go, but judging from the preview footage, Matthew and Richard are set to duke it out. (PBS)

But tonight, Homer, Marge and company hit that remarkable milestone, and they're still going strong. (Fox) ... A couple of clowns are joining "The Amazing Race." No, that's not a joke. A pair of circus clowns (husband and wife) are among the teams as Season 20 opens. Our advice? Leave the floppy shoes at home. (CBS) ... Call it reality TV inbreeding. The new season of "Celebrity Apprentice" features several contestants who earlier appeared on other unscripted shows, including Clay Aiken ("American Idol"), Victoria Gotti ("Growing Up Gotti") and Teresa Giudice ("The Real Housewives of New Jersey").
