1) “American Idol,” 8-11 p.m., ABC. The finale has two Southerners – Will Mosely, 23, from Georgia, and Jack Blocker (shown here), 25, from Texas – and Abi Carter, 21. Both guys auditioned with original songs; Carter did a Billie Eilish song, which fits; like Eilish, she’s a Californian who was home-schooled. Before the results, we’ll hear Jason Mraz. Seal, CeCe Winans, Cody Johnson, Wynonna Judd and more.
2) “MaryLand” and “Guilt” finales, 9 and 10 p.m., PBS. Both shows have smart scripts (centering on mismatched siblings), but they head in opposite ways. “MaryLand” ends quietly, as sisters adjust to the idea of their late mother’s secret life. “Guilt” bristtles with plots and schemes, as brothers face thugs, loan sharks a scheming businessman and (at times) their own worst instincts.
3) “Equalizer,” 8 p.m., CBS. Last year’s season-finale saw Robym’s colleagues held captive. Now it happens again, this time with Mel being kidnapped. That’s followed by the “Tracker” season-finale, tracing two amateur storm-trackers who disappeared. At 10, “CSI: Vegas” wraps its third and final season, with an explosion in a lethal lab.
4) MORE FINALES:: All four Fox cartoons have their season-finales tonight. “The Simpsons,” “Krapopolis” and “Bob’s Burgers” will be back in the fall; “The Great North” will wait until mid-season. And Showtime’s “A Gentleman in Moscow” has its finale at 8 p.m., rerunning at 11. You can catch the full eight-parter, starting at 2 p.m.
5) “Interview With the Vampire,” 9 p.m., AMC, rerunning at 10:10 and 11:20. Now we learn how Louis met Armand, 77 years ago in post-war Paris. Along the way, there are two potent moments – a vampire stage show for an audience that doesn’t realize how real it is; and a letter to Louis from Lestat, the man he loved and killed.
