What to watch on Thursday, May 2...
8pm, The CW
The Vampire Diaries
With Elena stubbornly refusing to reactivate her humanity, the Salvatore boys decide they’ve got to be cruel to be kind in “She’s Come Undone.” In other supernatural shenanigans, Bonnie offers Katherine a fishy bargain, Matt and Rebekah bond, and Caroline has a risky run-in with Klaus, who’s putting on this weirdly strained Cajun accent all of the sudden.
The Big Bang Theory
Two generations of CBS sitcom stardom collide when Bob Newhart guest-stars as Professor Proton, a former children’s show host who Sheldon and Leonard hire for a private performance in “The Proton Resurgence.” No word on whether the professor will bring along outdoorsy colleagues Neutron, his brother Electron, and his other brother Electron.
“Heroic Origins” traces Abed’s theory that the study groupers have been floating through one another’s lives for years and were fated to come together at Greendale. Meanwhile, Chang devises a cunning plan to annihilate the school, though he’ll probably say it like “CHANGnnihilate,” and everyone will fidget nervously until the next scene.
The hour-long “Livin the Dream” perturbs copy editors everywhere by not offsetting its slangy dropped “g” with an apostrophe (according to the press release), and also something about Andy trying to grow a pair so he can quit Dunder Mifflin and pursue acting. Dwight, meanwhile, is having a boffo workday after earning his black belt from sensei Michael Imperioli, and Jim arrives in Scranton to devote more time to Pam.
The New Direcheries-amours aim for higher ground when they turn their attention to the Stevie Wonder songbook in “Wonder-ful.” Also, Artie may not be overjoyed to receive news affecting both his future and his mom (Katey Sagal), and Rachel hopes her Funny Girl callback will have the producers saying, “isn’t she lovely?”
The docs’ efforts to lend Bailey support fall on deaf ears in “Do You Believe In Magic,” while Owen fears that foster care is in the cards for Ethan after an incident with the boy’s grandmother. On the medical front, Grey Sloan welcomes a craniofacial specialist to help a young patient, and the ER admits a magician’s assistant whose cadabra got painfully abra’d by mistake.
Person of Interest
The Machine is on the fritz in “Zero Day,” forcing the team to deal with its worsening virus alongside their hunt for a cagey tech maven. Could crackpot hacker Root (Amy Acker) be behind the chaos? Might Shaw (Sarah Shahi) lend her stonefaced assistance? And will Carter’s dangerous quest to nail Beecher’s killer draw any other Sweeps-worthy guest-stars?
SEASON 5 FINALE, 9:30pm, NBC
Parks and Recreation
Leslie commemorates her first year in office, April deals with some life-altering news, and Tom contemplates an attractive business opportunity as “Are You Better Off?” wraps up the fifth season. And wait... what’s this? Why, good God! That’s... Special Agent Bert Macklin’s music! What on Earth could lure the FBI’s finest out of retirement?!
Good news, everyone! A colleague of Jack and Alana’s has apprehended a notorious serial killer in “Entrée,” so he won’t be plying his fiendish trade any longer. Ehh whaaaaa? Another murder that matches the killer’s M.O.? And a possible threat to someone close to Jack, who’s already leaning on Hannibal’s shoulder as he grieves for his dying wife? Bad news, everyone!
Sebastian Moran rears his Vinnie Jones-looking head once more in “A Landmark Story,” shedding light on Moriarty’s possible role in a series of slayings. Will Sherlock’s investigation bring him any closer to his archnemesis? And will F. Murray Abraham’s turn as a hitman known as The Actuary spark a trend of professional killers with white-collar sobriquets? Maybe one of Joe Carroll’s cultists on The Following can snap up “The Claims Adjuster.”
The crew continues to hunt for the mole in “A Woman Scorned,” but in the process they uncover the most mind-boggling twist since Scandal’s last most mind-boggling twist. At the White House, Cyrus musters his energies in response to Mellie’s power play, while Fitz orders Jake to keep on keepin’ an eye on Olivia, which I suspect Jake won’t have even a tiny problem with.
