What to watch on Monday, October 26...
SEASON 4 FINALE, 8pm, ABC Family
Switched at Birth
Bay gears up for her first art show in “And Always Searching for Beauty,” while Daphne’s ambitions spark tension with Mingo as she considers an internship near Quinn. Elsewhere, the Kennishes confront Regina about Eric’s secret even as Kathryn and John deal with friction of their own.
8pm, Disney XD
Bill Cipher’s diabolical plan has been set into motion in “Weirdmaggedon, Part 1.” Can the Mystery Shack gang and the other good people of Gravity Falls foil it and save reality from going kerplooie?
Bridgit Pike reunites with her brothers and decides to chart her own course in “By Fire,” so if she wants to have tacos for dinner every night then by gum she’ll have tacos for dinner every night! Also looking to the future: Penguin and Galavan, who jockey for underworld supremacy, and Kringle and Nygma, whose relationship kicks up a notch.
8pm, The CW
“I Hope Josh Comes to My Party!” sees Rebecca throwing herself a housewarming in hopes of drawing one guest in particular (you get zero points for guessing who). But first she must overcome her deep-seated fear of party-hosting, and bolster her somewhat sparse social circle.
The Big Bang Theory
Sheldon and Leonard turn to a shady black market dealer (Michael Rapaport) when a nationwide helium shortage frustrates scientists and dads who like to do chipmunk impressions at birthday parties alike. Elsewhere in “The Helium Insufficiency,” Penny and Bernadette set Amy up with a dating app to get her back in the romantic game.
SERIES PREMIERE, 8:30pm, CBS
Melissa Benoist harnesses the power of Earth’s yellow sun as the eponymous Kryptonian hero in the latest DC Comics adaptation from producer Greg Berlanti (though one not, for now, set in the same universe as Arrow and The Flash). The pilot finds young Kara Zor-El deciding to finally don the cape and take up the family superheroing business.
9pm, The CW
Jane the Virgin
While Jane and Rafael plan Mateo’s baptism, Rafael comes to grips with the news that Petra has her own bundle of joy on the way. Elsewhere in “Chapter Twenty-Five,” Xo sets aside her own misgivings to help Rogelio, who offers Michael advice about Jane, who mulls enrolling in a now-available graduate program she had long set her sights on.
In “Say No to the Dress,” Jenna encounters myriad obstacles on the road to her dream prom. I, for one, am delighted to see that high schools are finally combining Prom Night with American Ninja Warrior.
While Lauren and Amy throw a bash in “The Deep End,” Karma reinvents herself. In a disconcerting coincidence, both plans require several jars of spinach dip.
SPECIAL TIME, 9:30pm, CBS
The 90-minute “Tech, Drugs, and Rock ‘n Roll” finds Walter’s computer infected by a vile virus that corrupts the team’s new smart building project. Consequently it becomes less “helpful” smart and more “criminal mastermind who will destroy everyone within its grasp” smart.
The team must disable an app that allows assassins to track government vehicles, and the app’s creator lends a hand. (Believe it or not, none of this violates Apple’s Terms of Service.) Meanwhile in “Cede Your Soul,” Jane and Weller’s relationship veers into the personal, and Zapata wrangles with an ethical quandary.
The Gerhardts’ hunt for Rye kicks into a higher gear in “The Myth of Sisyphus,” yet even shouting “Olly olly oxen free!” fails to draw out their elusive quarry. Meanwhile, Peggy stumbles upon a new theory about the Waffle Hut Shooter, and Lou takes a trip to Fargo (hey, that’s the name of the show!).
