Here’s what’s happening in the world of television for Thursday, August 16. All times are Eastern.
Detroiters (Comedy Central, 10:30 p.m.): As the men-children of Cramblin-Duvet head into their second-season finale, Detroit’s doofiest ad agency faces its greatest challenge since Tim’s old man went off the deep end: Sam may be a father himself, meaning it might be time for him to find work in a stabler field than local commercials. It’s a lot of dad stuff, but this season finale, like every episode preceding it, is grounded in the sometimes contentious, always sweet friendship at the center of the show. Will “Royals” spell the end of that friendship? And what does this mean for the future of Detroiters? How are they ever going to land that Dodge account if there isn’t a third season of the show?
Trial & Error (NBC, 9 and 9:30 p.m.)
Nightwatch Nation (A&E, 10 p.m.): In the criminal justice system, the people are represented by two separate, yet equally important, groups. But let’s forget about those jokers for a second: This Dick Wolf-produced series follows real-life EMTs in cities across the United States.
