FINALE WATCH: Quirky city-kid-moves-to-the-suburbs comedy “Suburgatory” (ABC at 8, 8:30 p.m.) has never been a ratings monster, but it earned enough goodwill for a second season — can it go on for a third? In the final two episodes of the season, Tessa decides she’s had enough when her dad sells their house so he can move in with his girlfriend, who’s also the mother of Tessa’s nemesis. Meanwhile, Noah tries to get over the betrayal of the love of his life (his housekeeper) dating his therapist.

At this point in the season, it’s safe to say that we’ll probably have a female winner on “American Idol” (Fox at 8) for the first time in years, because of a lackluster pool of male singers. The remaining contestants try to impress the judges on performance night.

RETURNING SHOW: “Locked Up Abroad” (National Geographic at 9) kicks off Season 7 with an episode featuring Sen. John McCain (R-Ariz.) and Ernie Brace, who were POWs during the Vietnam War.

Shawn has regrets about a case involving a mysterious woman on “Psych” (USA at 10) and thinks back to the beginning of the investigation to reflect on what he would have done differently.

On “It’s a Brad, Brad World” (Bravo at 10), starring Rachel Zoe’s former assistant-turned-stylist, Brad thinks it will be a breeze when he’s sent to Dubai to launch a fashion brand — but runs into trouble with a culture clash and disappearing models.

The 20-somethings and seniors clash again when they must complete an online-dating challenge on “Forever Young” (TV Land at 10), but it gives them the chance to offer relationship advice across generational lines.

Actors Harrison Ford and Anthony Mackie are on “Jimmy Kimmel Live” (ABC at 11:35), along with a performance by M83.
