“The Blacklist” closes out its highly successful freshman season with an episode that producers promise is a “game-changer.” That’s great, but what we really want to know is the true identity of Liz’s mysterious husband (Ryan Eggold). 10 p.m., NBC (Channel 5).
“NCIS,” which usually goes out on a suspenseful note, instead ends its season with an emotional one. The episode is a tribute to the late Ralph Waite, who played Gibbs’ (Mark Harmon) father. 8 p.m., CBS (Channel 7).
The Season 5 finale of “Glee” opens with everyone at a crossroads as Rachel (Lea Michele) ponders leaving Broadway behind to try out television. Our advice? Don’t do it, Rachel! 8 p.m., Fox (Channel 13).
Do you hear wedding bells? On “Modern Family,” Mitchell and Cameron’s (Jesse Tyler Ferguson, Eric Stonestreet) big day is finally here. But we suspect their walk down the aisle won’t go off without a hitch. 9 p.m., ABC (Channel 4).
The season finale of “The Vampire Diaries” apparently puts some lives at risk. In other words, it’s business as usual. 8 p.m., The CW (Channel 11).
Break out the Kleenex. In the Season 10 closer of “Grey’s Anatomy,” we’re forced to bid farewell to hard-driven surgeon Cristina Yang (Sandra Oh), one of TV’s great characters. We’ll be OK, but what about poor Meredith (Ellen Pompeo)? 9 p.m., ABC (Channel 4).
The third season of “Grimm” ends with the long-awaited wedding of Rosalee and Monroe (Bree Turner, Silas Weir Mitchell). Should be fun — as long as the guests don’t try to kill each other. 9 p.m., NBC (Channel 5).
Earlier in the day on “The View,” the show’s esteemed creator and co-host was scheduled to slip off into retirement. Tonight brings “Barbara Walters: Her Story,” a two-hour retrospective special that recalls an incredible, groundbreaking television career. 9 p.m., ABC (Channel 4).
The season finale of “Saturday Night Live” serves as a homecoming for Andy Samberg (“Brooklyn Nine-Nine”), who returns to the show for his first hosting gig. The musical guest is St. Vincent. 11:35 p.m., NBC (Channel 5).
