What to watch on Thursday, October 3...
SEASON 5 PREMIERE, 8pm, The CW
The Vampire Diaries
As Elena and Caroline settle into their new college dorm room, the appearance of their unexpected third roomie raises suspicion. Elsewhere in “I Know What You Did Last Summer,” newly human Katherine appeals to Damon for protection, Jeremy re-acclimates to life among the living, Matt and Rebekah return from their whirlwind European voyage, and Silas extends Mystic Falls’ streak of “town parties that end in violent terror” to 3,214 straight.
The Big Bang Theory
In “The Scavenger Vortex,” Raj devises a scavenger hunt where each clue is more insidious than the last. Naturally, the gang’s friendly competition quickly escalates into an intense, relentless battle of wills.
SERIES PREMIERE, 8:30pm, CBS
Newly single newsman Will Arnett finds his life upended by the divorce of his parents (Margo Martindale and Beau Bridges). Compounding the calamity, his mother decides to move in with him while his father crashes with his sister (Jayma Mays), throwing their entire family dynamic into disarray.
SERIES PREMIERE, 8:30pm, NBC
Welcome to the Family
A young man and woman dating in secret find themselves with a baby on the way, forcing the couple to come clean to their families—and forcing the two very different clans, one white and one Latino, to reluctantly merge into one.
SERIES PREMIERE, 9pm, NBC
Sean Saves the World
A divorced dad (Sean Hayes) must adjust when his teenage daughter moves in with him full-time, throwing off the careful balance of his home life, his flourishing career, and the intrusions of his mother (Linda Lavin). Meanwhile, co-star Megan Hilty continues searching for ways to escape her contractual obligations to NBC Universal.
SERIES PREMIERE, 9pm, The CW
“Always and Forever” revamps (no pun intended… okay maybe half-intended) last year’s backdoor pilot of this Vampire Diaries spin-off, which follows brooding baddie Klaus to New Orleans. There, he clashes with his erstwhile protégé Marcel, now the Big Easy’s big boss, while juggling the demands of older brother Elijah and lycanthrope Haley, who’s carrying Klaus’s bun in her oven. (Note: The show will debut in its regular timeslot next Tuesday at 8pm.)
The Fab However-Many-Kids-Are-in-New-Directions-I’m-Not-Bothering-to-Google-It continue their tour through The Beatles’ songbook in “Tina in the Sky With Diamonds.” Tina’s ambition rages after she’s nominated for prom queen, nixing her chances of getting by with a small amount of assistance from her compatriots. Elsewhere, Rachel and Santana continue working at a Broadway diner, where their supervisor tries to schedule them for one 24-hour period more than is comprised by a standard Gregorian calendar week.
Life at home with a newborn—and away from the hospital—takes its toll on Meredith and Derek in “Everybody’s Crying Mercy.” Elsewhere, Arizona strives to mend her busted marriage, Alex and Jo adjust to couplehood, Owen and Jackson butt heads over the hospital’s finances, and April waits for the results of her boards exam.
SEASON 3 PREMIERE, 10pm, ABC
Outed as the president’s mistress, Olivia and her team must align with an unexpected partner to contain the fallout. Meanwhile in “It’s Handled,” Liv’s father Rowan is dead-set on carrying out his orders, and even his daughter and a hopping R&B-scored montage can’t derail him.
After a prestigious mathematician is slain in “Solve for X,” Holmes and Watson must untangle both the mystery of his death and the knotty equation he was analyzing. Off the detective beat, Joan is torn when a former patient’s son seeks financial aid from her.
Jasmine and Crosby’s bundle of joy is crying up a storm, much to Jabbar’s detriment. Elsewhere in “All Aboard Who’s Coming Aboard,” the campaign takes its toll on Adam and Kristina, Julia forms a fast friendship with a school parent volunteer, Zeek dodges a discussion with Camille, and Hank's advice to Sarah rubs Adam the wrong way.
12am, Cartoon Network
Blake’s been abducted, as the title “Blaken” would suggest. Can the power of television spirit him to safety? Well of course it can, don’t be ridiculous. There’s nothing the power of television can’t do!
12:15am, Cartoon Network
Did you ever wonder “How Piper Got Her Groove Initially”? If so, this week’s episode seems set to answer your prayers.
