What’s Worth Watching: ‘Scorpion’, ‘Mike & Molly’, ‘Dancing With The Stars’ and more for Monday, April 25

Scorpion (9/8c): This enjoyable sleeper hit wraps its second season with Toby (Eddie Kaye Thomas) in peril, when a former team member kidnaps him and holds his life as hostage to his extraordinary demands. Cliffhanger alert?

Mike & Molly (8:30/7:30c, CBS): Melissa McCarthy fans who’ve been clamoring for the sitcom’s return—it’s been MIA since February—are in for a glut as CBS burns off the back end of the final season in just a few weeks. After this week’s episode, in which Molly (McCarthy) may put Mike (Billy Gardell) in the doghouse after bringing a stray mutt home, CBS will air back-to-back episodes on Mondays through the May 16 finale. You’d think there’d be more fanfare for one of comedy’s most popular stars.

Dancing With the Stars (8/7c, ABC): The remaining celebs, including breakout star Nyle DiMarco (reunited with pro Peta Murgatroyd after last week’s “switch-up”), have big dance shoes to fill this week, as they take on fondly remembered routines from movies and videos, including the title track of Footloose, the climactic number of Hairspray, Michael Jackson’s “Bad” and Janet Jackson’s “Nasty.” In what sounds like the biggest stretch and challenge, Doug Flutie will attempt Bollywood with “Jai Ho!” from Slumdog Millionaire. More like “Oh No.”

Inside Monday TV: Already renewed for next season, Fox’s diverting Lucifer (9/8c) is framed for murder in the season finale, and you’d think a devil like him would be used to such things by now. … To mark the 100^th anniversary of the National Park Service this year, PBS is reviving Ken Burns’ visually spectacular tribute to The National Parks: America’s Best Idea as a week-long series (9/8c through Saturday, check local listings at pbs.org). … Can’t get into Broadway’s Hamilton? AMC offers up its own take on revolutionary fervor with the third-season premiere of Turn: Washington’s Spies (10/9cs), during which General Washington’s trusted spy Abe (Jamie Bell) covers up a murder, while traitorous Benedict Arnold (Owain Yeoman) settles into life in Philadelphia, and we all know how that turns out.
