someone somewhere
10pm, Sky Comedy
Among all the best-watched series of recent years, this story of a woman left behind in a big city to return to her childhood home in Kansas is at the top of the list. It’s a serious, belly-laughing emotional journey that has raw, sweet, heartbreak and doesn’t feel like an artsy vibe at Sundance. The glorious final season begins with a double-bill in which Sam (Bridget Everett) looks into adopting a dog while moving in with Joel’s former roommate with his friend, Geoff. Tune in to an hour of glorious TV that spans from tears to joy – and you’ll hear the most creative rendition of those futures around the mountain ever. Alex Duggins

Renaissance – Blood and Beauty
9pm, BBC Two
Who is really “Florentine’s favorite son”? Michelangelo, in his old age played by Charles Dance? His superstar rival Leonardo da Vinci? Or Raphael’s latest youth? With additions from contemporary artists including David LaChapelle and Alison Lapper, this event explores Michelangelo’s most sacred commission: the figure of David. Ellen E Jones
24 hours in police custody
9pm, Channel 4
A surprising and tragic situation for Luton police in this episode of the police procedural documentary series. The call leads to the flat where they find a man lying unconscious on top of a woman. But who are they and how did they get there? Neither of them has any local ties, and therefore these questions have no clear answers. PH
Dune: Prophecy
9pm, Atlantic Sky
The political machinations of the mystical spin as the grand prequel continues grand. Valya (Emily Watson) returned to the fold of House Harkonnen before the big Council meeting. But back at the nursery of the sisters in a bed for space for young witches, Tula (Olivia Williams) must contend with a psychic attack. Graeme Virtue

Rosaline (Karen Maine, 2022), 9pm, Film4
Karen Maine’s relatable comedy takes a teen angle on Shakespeare’s Romeo and Juliet, but sends the tropes of high school comedy back to medieval Verona. Kaitlyn Dever is the titular Rosaline Capulet, invisible in the Bard’s play, but here she’s a smart, career-minded girl … who also loves Kyle Allen’s floppy boy Romeo Montague. That is until her new cousin Julia (Isabella Merced) turns her head. Dive bars, sports (games), stoners and youth business, it will appeal to fans of Clueless, and it has a terrible star in Dever.
