Here’s what’s up in the world of TV for Monday, March 6. All times are Eastern.

Top pick

Supergirl (The CW, 8 p.m.): Although the episode is titled “Exodus,” it boasts a new arrival, as Teri Hatcher will reportedly make her debut as some as-yet-unknown villain. (Could all those years spent dealing with Lex Luthor have warped Lois’ mind?) Elsewhere, Alex searches for Jeremiah, and there are two potential journalism coups: Kara’s investigation of a series of alien kidnappings, and a Snapper Carr exclusive with Supergirl herself. Resident muckraker and Supergirl reviewer Caroline Siede will get to the bottom of things.


Regular coverage

WWE Monday Night RAW (USA, 8 p.m.)

Bates Motel (A&E, 10 p.m.)

Humans (AMC, 10 p.m.)

Wild card

Milo Murphy’s Law (Disney XD, 7 a.m.): “Weird Al” Yankovic has a kids’ show? Yes, and it’s delightful. This animated series, from Phineas And Ferb’s Dan Povenmire and Jeff “Swampy” Marsh, is about a plucky boy, the titular Milo, who lives with quite literally the world’s worst luck. But he remains upbeat in the face of overwhelming odds because he’s got great friends and a backpack that would make Batman envious. Who couldn’t use a dose of that kind of optimism right now? So set your DVR for “Family Vacation,” which sees Milo bringing his bad luck to a whole new set of people. (We promise, it’s a lot more fun than it sounds.)
