1) “Extended Family,” 8:30 p.m., NBC. This show often has Jon Cryer as TV’s usual bumbling dad. Tonight, however, offers a neat exception: With his ex-wife elsewhere, Jim (Cryer, right) and her new boyfriend (Donald Faison, left) are supposed to watch the kids. Emerging is a teen trauma – the sort of thing Jim is really good at. Cryer, who used to star in teen-trauma movies, handles it neatly.
2) “La Brea,” 9 p.m., NBC. Somehow, this complicated, time-fractured series is supposed to be resolved in the next two episodes. For now, the survivors learn of a traitor and find out where Eve was taken; there’s a deadly confrontation, That’s followed at 10 by “Quantum Leap,” a consistently better series. Ben is in Mexico in 1953, as estranged siblings try a dangerous treasure hunt.
3) “Finding Your Roots,” 8 p.m., PBS. The past can be intriguing for people with multi-racial roots. The backgrounds of Sunny Hostin (of ABC News) and Jesse Williams bring stories of triumph after slavery, plus others. The roots go back to Puerto Rico and Sweden … and even to someone who arrested girls for the Salem witch trials.
4) “FBI” and “FBI International” season-finale reruns, 8 and 9 p.m., CBS. With its season beginning next week, CBS is rerunning lots of finales. “FBI” has a religiously motivated serial killer; “International” sees a stolen missile on the black market. At 10, “FBI: Most Wanted” also has a rerun (a TV anchor is slain), but not of a season-finale.
5) “Good Trouble,” 10 p.m., Freeform. This has been an excellent drama throughout its five-year run. Now, starting its final five episoders, it wanders. One story – introducing an older man to a gay nightclub – is clumsy and cartoon-ish. Others veer toward melodrama, yet have terrific characters at the core.
