FINALE WATCH: It takes two hours to conclude this mortifying season of “The Bachelor” (ABC at 8 p.m.), which, according to last week’s sneak peek, has the finalists in St. Lucia and, after a surprise visit from a past contender, basically every contestant in tears.

Rachel’s the lead in “Funny Girl” in New York City on “Glee” (Fox at 8), and Santana’s auditioning to be her understudy, which is unsurprisingly disastrous.

Much to Jess’s dismay, Abby’s sticking around on “New Girl” (Fox at 9) once she realizes her feelings for one of the guys. Linda Cardellini guest stars.

Premiering in its regular time slot, “About a Boy” (NBC at 9) addresses babysitting duty when Fiona has a job interview, and a last-minute invitation to a party complicates just about everything.

RETURNING SHOW: After a four-month hiatus, “Rizzoli & Isles” (TNT at 9) returns to finish its fourth season with Jane and Maura on the search for a kidnapping clown.

Also finally in its regular time slot is “Growing Up Fisher” (NBC at 9:30), which has Mel figuring out how he can reveal that he’s blind to his biggest client, while Henry is mistaken for being blind when he borrows Mel’s guide dog.

SERIES PREMIERE: With a bit of science and a smattering of Jedi mind tricks, brothers Ross and Clark Edwards can tailor a plan to influence any life-altering situation, thereby making their clients’ dreams come true on “Mind Games” (ABC at 10). In the opener, their client is a young boy with a heart condition who has recently been denied an experimental treatment.

SERIES PREMIERE: Take a peek at the underground world of arm-wrestling on “Game of Arms” (AMC at 10), where we follow five arm-wrestling clubs, and their friends and families, as they hit the road and wager their rent money, reputations and relationships in the pursuit of victory.

RETURNING SHOW: “Perception” (TNT at 10) is picking up its second season where it left off in August, with Pierce helping an autistic teen who is under investigation for murder.

Actor Paul Rudd and former NBA star Shaquille O’Neal stop by “The Tonight Show Starring Jimmy Fallon” (NBC at 11:35), with a stand-up set from Hannibal Buress.

U.S. Olympic gold medal winner Ted Ligety, animal trainer Jack Hanna and actress Kat Dennings are on the “Late Show With David Letterman” (CBS at 11:35), with music from Lo-Fang.

Actors Kevin Spacey and Ansel Elgort come to “Jimmy Kimmel Live” (ABC at 11:35), with a musical performance from Benmont Tench.
