On TV this Monday: J.J. Abrams uncorks a new island mystery, the Broke Girls get a neighbor, birthday girl Betty White wants to punk you, a Lost Girl finds herself on Syfy and more. As a supplement to TVLine’s original features (including several stories on Gossip Girl‘s winter premiere), we’ve singled out 10 shows to keep on your radar.
8 pm Alcatraz (Fox) | Two-hour series premiere: A detective (Sarah Jones, Sons of Anarchy) and Alcatraz historian (Jorge Garcia, Lost) team up with a secret agency dedicated to finding inmates from the infamous prison who went missing 50 years ago and are reappearing today. Sam Neill (Jurassic Park) and Parminder Nagra (ER) also star, and J.J. Abrams (Lost) is an exec producer. (Read our First Impression.)
8 pm Pretty Little Liars (ABC Family) | With Lucas missing and questions surrounding what happened out on the lake, Hanna’s reluctance to help only causes more problems; Spencer’s new lead about “A” guides her to an unexpected place and revelation.
8 pm How I Met Your Mother (CBS) | In the hitcom’s 150th episode, Lily and Marshall officially move to the suburbs only to realize that Lily’s bossy father refuses to move out of their house. (Check out photos here.)
8:30 pm 2 Broke Girls (CBS) | Max and Caroline are suspicious of a new upstairs neighbor (Jennifer Coolidge, Best in Show). (Read more about Coolidge’s recurring character.)
9 pm Being Human (Syfy) | Season 2 premiere: Nora starts her transition into a werewolf; Aidan fearfully prepares for his meeting with the Elders; Sally goes haywire with her new powers. (Oh, and this guy will be returning.)
9 pm Two and a Half Men (CBS) | Zoey tries to coerce Walden into cutting his hair and shaving (and apparently it works; Ashton Kutcher debuted a jarringly clean-cut appearance at the TCA winter press tour last week). Meanwhile, Alan and Lyndsey rekindle their relationship.
9:30 pm Betty White’s Off Their Rockers (NBC) | Series premiere: After celebrating her 90th birthday with an 8 o’clock NBC special, America’s sweetheart debuts this new hidden-camera show, sending a fearless band of senior citizens to the streets to pull pranks on the younger generation.
10 pm Lost Girl (Syfy) | In the U.S. premiere of this Canadian series, Anna Silk (The Ghost Whisperer) stars as Bo, a Succubus who feeds on human energy — sometimes with fatal results. Refusing to embrace her supernatural clan system and its rigid hierarchy, she searches for the truth about her own origins. Ksenia Solo (Life Unexpected) and Kris Holden-Ried (The Tudors) also star.
10 pm Hawaii Five-0 (CBS) | McGarrett is rocked to his core when Chin Ho reveals shocking news about Joe White; Danny plays midwife for his ex-wife when she goes into early labor.
10 pm Castle (ABC) | Mayor Weldon (guest star Derek Webster, Damages) — the man whose political clout keeps Castle at Beckett’s side — lands in the crosshairs when a woman is found dead in a car that traces back to his motor pool. (Read about Beckett’s conflict here.)
