TV HIGHLIGHTS

Marvel’s Agents of S.H.I.E.L.D., 8 PM on Ch. 22 and Ch. 9:

It’s hard to tell whether actual time travel is a component of the new episode “From the Ashes,” but in any case, several of the S.H.I.E.L.D. agents are forced to confront ghosts from their past, metaphorical or otherwise, before they can move forward. That’s the decision they reluctantly reach once they grasp that they are out of answers — and running out of time. Clark Gregg, MingNa Wen and Chloe Bennet star.

Andi Mack, 8 PM on DIS; 10:55 PM on DIS; 11:35 PM on DIS:

The groundbreaking Disney Channel sitcom wraps up its three-season run with a finale called “We Were Here.” When Celia (Lauren Tom) leaves town, Andi and Bex (Peyton Lee, Lilan Bowden) throw another party. Elsewhere, Buffy and Cyrus (Sofia Wylie, Joshua Rush) swap tales of romantic disappointments, while Andi shares a secret. During its run, “Andi Mack” broke new ground for Disney as the network’s first serialized show, the first series focused on an Asian-American family, and the first to feature an LGBTQ character announcing, “I’m gay.”

Ghosts of Morgan City, 9 PM on TRAV; 12 AM on TRAV:

In the new episode “Berwick Bloody Four,” paranormal investigator Jereme Leonard, former FBI agent Ben Hansen and psychic medium Sarah Lemos explore reports of poltergeist activity believed to be connected to a grisly murder in Berwick, La. The case hits disconcertingly close to home when the team detects what appears to be a link between a baby doll taken from the crime scene and paranormal activity that is kicking up at their own headquarters.
