1) “Agents of SHIELD” series finale, 9 and 10 p.m., ABC. A hugely ambitious effort – seven seasons and 136 episodes, leaping across planets and across time – concludes. Sybil – who got inside the computer system – and Nathanial are close to eliminating SHIELD from ever existing. Leo Fitz (Iain De Caestecker, shown here in a previous episode), who was killed in one timeline, is back. So are Piper, Davis, Enoch and Flint, in battles to save the world.
2) “The 100,” 8 p.m., CW. You can make it a full sci-fi evening by catching this surprisingly good episode. Right now, Clarke and her colleagues are at a standstill: The heroic Bellamy was apparently killed; The Shepherd and his disciples are demanding what they call “the key” to ultimate victory. What follows tonight is basically a two-person drama; beautifully written, it’s acted with subtle perfection.
3) “The Coroner,” 9 p.m., CW. It’s an extraordinary night for this micro-network, with two excellent hours. In last week’s opener, Dr. Jenny Cooper’s husband died of a heart attack, leaving her and their teen son with a mountain of debts from his gambling losses. Now she’s Toronto’s crime-solving coroner. In this hour, she uses her own experience to break through to a young widow.
4) “World of Dance” finale, 9:01 p.m., NBC. Here’s another step in a no-rerun night. On Tuesday, the show put two more acts into the championship. That gives us four varied and gifted contenders.
5) “Impact of Hate: Charlottesville,” 9-11 p.m., Investigation Discovery, rerunning at midnight. Three years ago today, a car slammed into counter-protesters in Virginia, killing one person and injuring 19. The driver was convicted of murder, but controversy lingers. The event started with a “Unite the Right” march that included white supremacists and alt-right; President Trump later said there were “very fine people on both sides.” This special talks to survivors and to Mike Signer, the former mayor.
