Prepare yourselves for the finales:
“Dallas” (Monday, 9 p.m., TNT)
It feels like this soap opera just came back (the series returned at the end of February), and already the oily family is winding up a spring mid-season finale — which of course gives the classic saga another opportunity for one of its trademark cliffhangers. So, after a half-season of sleeping with his step-cousin and tossing his mom in the psych ward, John Ross — played by Josh Henderson, who’s been fantastic as he’s evolved into a tormented evil-doer — will face the wrath of wife Pamela (Julie Gonzalo), who’s discovered his philandering (among his other misdeeds).
“Scandal” (Thursday, 10 p.m., ABC)
In any other series, if Mama heard that an explosion would rock the nation’s capital in the season finale, her heart would race at the prospect of mass destruction and characters in peril. But in the hyper-reality of Olivia Pope’s (Kerry Washington) DC, the president murders people, a clandestine agency can make anybody disappear, the First Family allows their assorted lovers to decide the fate of the country, and the chief of staff sends his gay lover to his death. So a bomb on Election Day? Meh.
“Warehouse 13” (Monday, 9 p.m., Syfy)
As this collection of history’s mystical oddities launches its final six episodes, we pick up right where we left off, with Claudia (Allison Scagliotti) fighting Giles, I mean Anthony Head’s Paracelsus, who wants to take over the Warehouse through all of time. Expect the typical sci-fi last-season fare, with plenty of callbacks and a parade of familiar faces.
“Suits” (Thursday, 9 p.m., USA)
In the penultimate episode, Mike (Patrick J. Adams) finally got the chance to escape his life of lying with an offer to exit the law firm for a job as an investment banker. But instead of putting his knack for stretching the truth toward a field that rewards liars and cheats, he stuck with the other field that, well, rewards liars and cheats (but in a different way). And so he adds his name to the Bar (which nobody else ever checked before now?!?) and sets up his colleagues and friends at Pearson Specter — not to mention their clients — for a disastrous end. Željko Ivanek guest-stars in the third-season finale.
“Mad Men” (Sunday, 10 p.m., AMC)
Don’t get your mod dress in a bunch — this is only the first half of the final season of Don Draper’s (Jon Hamm) long fall from grace. Who’s up for a trip to California?
