1) “B Positive” season-finale, 9 p.m., CBS. One of TV’s best – and most undernoticed – comedies wraps its second season. As Gina, Annaleigh Ashford brings a Lucy-like touch, mixing intelligence with a random/vague outlook. On Broadway, Ashford has had two Tony nominations and a win (shown here); on TV, the Emmys and others have ignored her. This season, Gina bought the retirement home where she used to work; tonight, she considers selling it.
2) More season-finales, Fox. At 8 p.m., “Joe Millionaire” concludes. The two guys each choose a mate; those two women then learn if they got the rich one or the other one. And at 9:30, “Pivoting” wraps. The season started with three women at the funeral of their friend; it ends on her birthday, as they take her ashes for a night on the town.
3) “Grey’s Anatomy,” 9 p.m., ABC. It’s almost time for Dr. Hamilton’s long-awaited, groundbreaking surgery. Meredith, Amelia and the others prepare. Meanwhile, Baily receives a surprise offer and the impatient Owen turns out to be a difficult physical-therapy patient,
4) “Dicktown,” 10 p.m., FXX, rerunning at 10:31 and 11:04. This animated series, which debuted last week, spun off from “Cake,” a collection of comedy odds and ends. John Hodgeman and David Rees created it and play John Hunchman and David Purefoy, detectives in Richardsville, better known by its nickname. Each episode has two stories; tonight’s first one is quite clever (albeit with very adult language); the second is OK.
5) ALSO: We’re heading into a crowded week for streamers. On Friday, Disney+ debuts Pixar’s “Turning Red” and Apple TV+ has Samuel L. Jackson’s superb performance in “The Last Days of Ptolemy Gray.” Today has new episodes of “Picard” (Paramount+) and “The Dropout” (Hulu) and the start of a Peacock comedy: “Bust Down” focuses on four friends who work at a casino in Gary, Ind.; it includes Chris Redd of “Saturday Night Live,” with Lorne Michaels of “SNL” producing.
