Will & Grace

NBC, 9 ET/PT

The revived sitcom has been on hiatus because of Thursday Night Football, but it returns tonight with some holiday cheer in “A Gaye Olde Christmas.” The episode finds Will (Eric McCormack), Grace (Debra Messing), Karen (Megan Mullally) and Jack (Sean Hayes) wishing they could have experienced New York in Old New York, but the past is not quite as romantic as they may have imagined.

CW Sara (Caity Lotz) is back in the game on “Legends.”
