What to watch on Thursday, August 20...
SEASON 1 FINALE, 8pm, ABC
The Astronaut Wives Club
As mankind takes its giant leap in “Landing,” the ladies are interviewed for a documentary about the space program. In less celebratory affairs, Gordo is overlooked for the next mission, Betty honors Gus’s legacy, and Trudy looks to the future. Later, the ill-fated Apollo 13 voyage launches.
8pm, The CW
Beauty and the Beast
In “Unbreakable,” Vincent and Liam team up to recover potentially damaging evidence, and of course to forge an unlikely yet genuine bond along the way. Well, unless Cat goes and ruins it by uncovering some nasty piece of Liam’s family history that could spell trouble.
A rift in her relationship with Blair brings April closer to Lucy, while Karen and Vivian each have news to share. Elsewhere in “Guilt by Association,” the hits just keep on comin’ for Joss. (The bad kind of hits, not like she’s suddenly become a successful recording artist.)
The contestants enjoy a day on a cruise ship in “Shut Up and Sew,” and teams of two must design looks suitable for a day-to-night transition. Tracee Ellis Ross will serve as guest judge, if she can tear herself away from the shuffleboard court.
SEASON 1 FINALE, 10pm & 10:30pm, Spike
Lip Sync Battle
Empire co-stars Taraji P. Henson and Terrence Howard bring their on-screen rivalry to the real (well, fake-real) world in the epic two-part finale.
SERIES PREMIERE, 10pm, IFC
A send-up of documentary series, created by Fred Armisen, Bill Hader, and Seth Meyers and hosted by Helen Mirren. It kicks off with “Sandy Passage,” which chronicles the Grey Gardens-esque existence of a reclusive mother and daughter.
Under the Dome
The Resistance joins forces with EvilCo overlord Hektor Martin to launch an anti-Dome offensive in “Legacy.” Big Jim and Julia, though, remain suspicious of their new ally, perhaps because he keeps tenting his fingers and cackling maniacally towards the sky.
10pm, Comedy Central
Forrest tackles matters spiritual and physical, as he first starts a cult and then undergoes enhancements designed to forge a perfect body.
Alex stumbles upon shelter in which he can tend to Noma’s wounds, even with the New Delphi army in hot pursuit. Elsewhere in “Lay Thee Before Kings,” Michael and Gabriel attempt a jailbreak, Claire calls for a parlay, and David enacts his plan.
A heatwave pounds the city in “Ninety Degrees,” prompting Jarvis to open up 15 Division as a public cooling station. (Though he draws the line at selling ice cream out of the back of a paddy wagon.) And as the officers try to put the corruption scandal behind them, Andy and Marlo search for a vanished volatile woman, while Oliver readjusts to walking a beat.
Charlie concocts a new plan to nab Germaine, and it may or may not involve some black paint on the side of a mountain and a hefty order of Acme products. Meanwhile in “Hand of Glory,” Mike wonders about Briggs’ motives in the Sarkissian case.
Gigi doubts Johnny’s commitment to the Sparkle Motion of fatherhood in “Tattoo You,” so she asks him to prove it by getting her name inked on his body.
“Murder!” finds Lina and Russ skipping work to investigate the occupant of their guest house. But will they dig up a couple of ‘90s-style suits and go full-on Scully-and-Mulder cosplay?
Comedy Bang! Bang!
In dire need of a guest, Scott bargains with Satan to procure the services of Ken Marino. (No word on which deity booked fellow guests Matt Besser and Bob Odenkirk, but I’ll guess Quetzalcoatl.) In less Faustian affairs, an Icelandic chanteuse performers her nation’s new anthem.
Geeks Who Drink
Former East Dillon Lion Grey Damon and Silicon Valley’s Josh Brener bring the classic jocks-vs.-nerds vibe to this week’s episode. Zach Levi, presumably, will be playing the role of the crusty old dean.
