The must-see event of the week: “The Office” wraps up after nine seasons with a retrospective and supersized episode.  Here are some other highlights for the week:

SUNDAY

A winner will be picked on “Survivor: Caramoan – Fans vs.  Favorites” (8 p.m., CBS). Following is the traditional reunion special, where Jeff spends about a minute interviewing earlier rejects we’ve long since forgotten about, and the rest of the time talking to or about the final three.

Emily reconsiders her quest for vengeance on the second-season finale of “Revenge” (9 p.m., ABC) . The show lost me midway through this season, but maybe this two-hour episode will bring fans like me back in the fold. Rumor has it a major character will die.

MONDAY

It’s the eve of Barney and Robin’s wedding on the finale of “How I Met Your Mother” (8 p.m., CBS) , which will end for good next season. (The show, not the wedding.)

Max and Caroline have new hope for bringing back their cupcake business on “2 Broke Girls” (9 p.m., CBS) as the season concludes with a heavy helping  of crude jokes. (Don’t need to have seen the episode to know that.)

TUESDAY

As other shows bid goodbye, “So You Think You Can Dance” (8 p.m., Fox) says hello. The 10th season kicks off with auditions. (Ten seasons? I’m always amazed how many seasons reality shows have under their belts…no wonder I’m feeling reality-show fatigued.)

Will Jess and Nick become an official couple? Will Cece go through with her wedding? Will Schmidt say something wildly inappropriate? Find out on the season-ender of “New Girl” (9 p.m., Fox). The finale of “The Mindy Project” follows, with Mindy deciding to go to Haiti.

“NCIS” (8 p.m., CBS) and “NCIS: L.A.” (9 p.m., CBS) also air their season closers.

WEDNESDAY

Other people vacation in Hawaii. Both Sam and Dean have spent summers in Hell and/or Purgatory. So it’s no wonder the brothers want to save the world (again) by permanently slamming shut the gates to Hell on the season finale of “Supernatural” (9 p.m., CW). I’m guessing Crowley will have something to say about that.

The original “CSI” (10 p.m., CBS) also finishes its 13th (!) season with a series of “Dante’s Inferno”-themed  killings.

THURSDAY

The big news of the night, of course, is the end of NBC’s “The Office,” with a retrospective at 8 p.m., followed by the series finale. The show has been building to what will no doubt be an emotional climax, as Angela hit bottom and lost her cats, Dwight finally became manager, and Pam and Jim worked to save their marriage. It makes me eager to see what the show’s creators saved for the finale. We’ll miss you, Dunder Mifflin.

On the finale of ratings powerhouse “The Big Bang Theory” (8 p.m., CBS), Leonard is offered a job in another country. How will Penny and Sheldon react?

It’s graduation day on “The Vampire Diaries” (8 p.m., CW). I have a feeling the residents of Mystic Falls will have to deal with more pressing concerns than finding a good seat for the ceremony and picking up the cake.

In the two-hour season finale of “Elementary” (9 p.m., CBS), there’s an imperiled Joan, more Moriarity machinations and a surprise from Sherlock’s past.

On “Grey’s Anatomy” (9 p.m., ABC), the doctors must start to get nervous as it gets close to May… the show’s season finales always mean helicopter crashes, shooting rampages, and other larger-than-life situations.  What’s tonight’s theme? A severe storm hits, and one doctor’s life is in danger. (Just one? “Grey’s” must be going soft.)

Then, “Scandal” (10 p.m., ABC) ends its sophomore season with a finale that promises to be, well, scandalous.

FRIDAY/SATURDAY

If you’re like me, you have shows clogging up your DVR. The weekend is a perfect time to play catch-up. Sometimes, I’ll set up a timer for a new show, uncertain if it’s any good or if it will last, and then suddenly I have a season’s worth to wade through. This practice helps me avoid duds (like “666 Park Avenue”), but sometimes, I’ll come thiiiis close to deleting something I’m really glad I didn’t. This week’s pick for show I’m glad I didn’t delete: “The Americans” on FX.  The drama stars Matthew Rhys and Keri Russell as Russian spies living in the U.S. circa 1981. It’s been renewed for a second season, so it’s safe to catch up on season one.
