A critical checklist of notable Tuesday TV:

This Is Us (9/8c, NBC): If shedding tears is your idea of a good time, this might just be the feel-good episode of the week, as Kate (Chrissy Metz) and her loyal mate Toby (Chris Sullivan) confront the tragic event revealed at the end of last week’s “Number One” episode. Unlike Kevin’s (Justin Hartley) addiction meltdown, the “Number Two” section of the midseason-ending trilogy does at least leave the viewer with a bit more hope for the couple reeling from this poignant setback, although not without moments of predictably deep angst. The episode also explores the often fraught relationship between Kate and her mother, Rebecca (Mandy Moore), whom she always feared disappointing. Let’s hope Randall (Sterling K. Brown) has an easier time of it next week—though we’re not counting on it.

Marvel’s Runaways (streaming on Hulu): Yet another Marvel comic-book adaptation about tormented young mutants, although with executive producers Josh Schwartz and Stephanie Savage (The O.C., Gossip Girl) at the helm, there’s a wry sensibility to the generation-gap conflict when a group of teens discovers their parents are part of a secret cabal of super-villains. Don’t you hate when that happens?

Fixer Upper (9/8c, HGTV): The fifth and reportedly final season of the hit home-makeover show featuring Chip and Joanna Gaines will feature special guests including former First Lady Laura Bush and football’s Tim Tebow. But first, the Gaines come to the aid of Matt and Samantha, a young couple moving from Austin, Texas to Waco in search of a family home. For a sentimental flourish, the Gaines turn to Matt’s woodworker grandfather to provide some handmade furniture before the grand reveal.

It’s Thanksgiving! Holiday-related storylines include an early special delivery on CBS’s NCIS (8/7c) for McGee (Sean Murray) and Delilah (Margo Harshman). … On CBS’s Bull (9/8c), Bull (Michael Weatherly) ends up working a new case alone after letting the rest of the team go home to their families. … Bradley Whitford, Katey Sagal and Jimmy Smits are among the special guests on a very funny episode of Fox’s Brooklyn Nine-Nine (9:30/8:30c) in which Jake (Andy Samberg) and Amy (Melissa Fumero) bring their parents together for a turkey dinner that goes messily awry. Back at the precinct, Capt. Holt (Andre Braugher) grills his underlings with Jack Webb ferocity when a special holiday pie goes missing.

Inside Tuesday TV: Emotional family histories are revealed to Madam Secretary’s Téa Leoni and Transparent’s Gaby Hoffman in a new episode of PBS’s Finding Your Roots With Henry Louis Gates (8/7c, check local listings at pbs.org). … A winner will be named on ABC’s Dancing With the Stars in a two-hour finale (9/8c). … A&E’s six-part Who Killed Tupac? (9/8c) enlists civil-rights attorney Benjamin Crump on an investigation into the murder of influential rapper Tupac Shakur more than 20 years ago.
