‘Ghosts’ in the Machine, ‘Poker Face’ Sees the (Judith) Light, ‘Celebrity Jeopardy!’ Final, New Blood on ‘SVU’

8:30/7:30c

Calling the ghostbusters! Actually, it’s the B&B’s new assistant, Freddie (Mike Lane), who begins to suspect there are spirits afoot in Woodstone Mansion. (If he only knew.) When he brings in a contraption called the Ghost Trap 2000, which purports to detect spectral energy and lure such beings into its metal box, will any of our lovable non-living friends fall for it? In other ghostly developments, Sasappis (Román Zaragoza) panics when Freddie sells his car, thus potentially depriving him of contact with his crush, the ditzy car ghost Jessica (Nichole Sakura).

The fun continues on the buzzy light-mystery series from Knives Out’s Rian Johnson, with guest stars Judith Light and S. Epatha Merkerson having a ball as crotchety, pot-dealing residents of a retirement home who are anything but retiring. Custodian and human lie detector Charlie (the terrific Natasha Lyonne) goes “full Cocoon,” bonding with these rambunctious ladies, sensing kindred rebel spirits—until she realizes these former 1960s radicals may be hiding a deadly secret, which has claimed a new resident as a victim. The Big Bang Theory’s Simon Helberg guests as the victim’s nephew. (And keep an eye on “the Fletchers,” a gaggle of crones addicted to watching crime stories on TV. They’d love Poker Face.)

Season Finale

8/7c

Some episodes of this amateur-hour game-show spinoff have been painful to watch, but along the way a few celebrity players have shown how seriously they take Jeopardy! Three have made it to the final round, where semi-final winners Wil Wheaton, Ike Barinholtz and Patton Oswalt face off for bragging rights and a $1 million payday for charity.

9/8c

Is the revolving door at TV’s longest-running crime drama about to welcome a new detective to the squad? Detective Terry Bruno (Kevin Kane, an Emmy winner as a producer of Inside Amy Schumer) has made quite the impression on Fin (Ice-T) during the squad’s recent escapades in the Bronx, earning a personal tour of the Manhattan branch of SVU. But other colleagues might need convincing, given that Bruno reaped a small fortune after suing the NYPD for wrongful termination when he dared to speak out about corruption. Elsewhere, the team leads a hunt for an ambulance driver accused of assaulting those who ride in his bus.
