It's a Wilson-centric episode on "House."

November sweeps are over, Christmas is approaching and preemption season has already arrived. In addition to multiple changes to Tuesday night’s schedule making room for a presidential address (see more below), KMOV is preempting CBS at 7 p.m. Wednesday, bumping “Rudolph the Red-Nosed Reindeer” to late night. and wiping out the heavily promoted Grammy nominations concert.  (See my later blog post for more on the Rudolph-Grammy saga.) On Friday, KDNL double-dips with the preemptions, eliminating “Ugly Betty.”
This is also a week for finales. “Sons of Anarchy” and “Sherri,” two shows that couldn’t be more different, wrap up their seasons at 9 p.m. Tuesday on FX and Lifetime, respectively. “Top Chef: Las Vegas” begins its season finale at 9 p.m. Wednesday on Bravo, concluding next week, and “Monk” bows out Friday on USA.
Here’s more.

“House,” 7 p.m. Monday on Fox
My favorite “House” character takes the spotlight as Wilson (Robert Sean Leonard) treats an old friend (Joshua Malina of “The West Wing”) suffering from cancer.

Presidential address, 7 p.m. Tuesday on Fox, CBS, NBC, ABC and cable news channels.
On ABC, the speech bumps “A Charlie Brown Christmas” and the new animated special “Prep & Landing” to next Tuesday, Dec. 8.
On NBC, “The Biggest Loser” airs 8-10 p.m., preempting “The Jay Leno Show.” This is the first time NBC has bumped Leno.
CBS previously had an “NCIS” repeat scheduled at 7; it won’t air.
Fox will delay the start of a two-hour “So You Think You Can Dance” but air it in full (delaying Channel 2 news) immediately after the speech.

“Scrubs,” 8 and 8:30 p.m. Tuesday on ABC
The sitcom you thought ended its run last spring returns with a mostly new cast of medical students and only occasional appearances by some of the original regulars. Expect plenty of Turk (Donald Faison) and John C. McGinley (Cox), though.

“Glee,” 8 p.m. Wednesday on Fox
In the next-to-last episode before “Glee” takes a four-month break, the Schuster marriage is “shaken to the core” — and about time, I say.

“Launch My Line,” 10 p.m. Wednesday on Bravo
A new series pairs successful people who want to launch clothing lines with professionals who can help them out.

“Monk,” 8 p.m. Friday on USA
Monk (Tony Shalhoub) finally gets closure on his wife’s murder as the series ends its run after eight seasons and 125 episodes. Don’t say “canceled”; the decision to wrap up was reportedly mutual for network, studio, producers and Shalhoub himself.

‘The 12 Men of Christmas,” 8 p.m. Saturday on Lifetime
In a new romantic comedy, Kristin Chenoweth stars as a marketing executive hired to promote the town of Kalispell, Mont. How better than to create a calendar featuring all the town’s hunky men?
