The Divide (9pm, WeTV) - Christine meets with Stanley Zale and asks if she can call upon his son Eric to be a character witness for Terry if there is a retrial. Meanwhile, Terry’s investigation into his own case puts him in a risky situation. (Don’t let the unusual channel fool you – this is a good show.)
Extant (9pm, CBS) - This isn’t pulling the numbers CBS wanted, so they’re burning off the remaining four episodes two at a time – two tonight and the final two next week. Tonight at 9, Molly searches for her baby and becomes convinced the agency took the child. At 10, Molly learns her baby is alive and sets out with Kern and Kryger to intercept the child before Sparks and Yasumoto can relocate him.
Legends (9pm, TNT) - Martin, Crystal and Troy Buchannan go undercover when a chemistry teacher and his family are kidnapped. The case takes on urgency when it’s feared the kidnappers will use the teacher to manufacture deadly gas.
Fish Mavericks (10pm, NBCSN) - This NBC Sports Network outdoor fishing show centers on captain Dave Schunke and his crew aboard Fish Circus as they travel around competing in fishing tournaments. It debuted a couple weeks ago with a show in the Bahamas, followed by a show in New Jersey (future episodes focus on Virginia Beach, Louisiana and Alabama). Tonight, in collaboration with the Wounded Warrior Project, the crew goes to New York to take U.S. Army veteran Robert Gill out to fish for striper, where Gill talks about how fishing helped save his life. This sounds very nice and potentially serious, so I won’t make any jokes about a fisherman named Gill.
Naked and Afraid Pop-Up Edition (10pm, Discovery) - Um, no comment.
