1) “Young Sheldon,” 8 p.m., CBS. After pausing last week for reruns, the show is back to its best storyline: Georgie, 17, lied about his age; now his ex-girlfriend, 29, is pregnant. (They’re shown here with his grandmother.) His mom (who was pregnant with Georgie when she married) was stunned when friends avoided her Bible club. Now it’s time to face the congregation. Sheldon is perplexed, but his twin sister speaks up for Georgie.
2) “Welcome to Flatch,” 9:01 p.m., Fox. After some so-so episodes, “Flatch” has a good one. Kelly obsesses on being a social-media “influencer” (and getting free stuff), but she’s never had more than 25 views. Now she concocts a surprise reunion between Father Joe and a colleague from his days in a Christian boy-band. That’s followed at 9:30 by Shrub getting a job detailing cars.
3) “Grey’s Anatomy,” 9 p.m., ABC. Two weeks from its season-finale, this show finds Bailey receiving an offer from Nick; also, a past patient of Link arrives with his pregnant wife. That follows a “Station 19” at 8 p.m., with a domestic disturbance between the parents of a trans teen.
4) “United States of Al,” 8:30, CBS. While waiting for word on whether it will be back next season, this good-natured show has been trying too hard to grab viewers. Riley has been sleeping with his ex-wife while her husband is at work … and earnest Al is skipping classes to be with a temptress. Neither action fits the character; tonight, Al’s friends start to worry.
5) “Death on the Nile” (2022), 9 p.m., HBO. For the second time, Kenneth Branagh directs himself in one of Agatha Christie’s Hercule Poirot mysteries. The result is the same as the first: Branagh is no Poirot, but he is a terrific director. Any flaws in the casting – and holes in the far-fledged plot – are patched up by the lush visuals of an engaging film.
