“Motive” (8 p.m., ABC): In the two-hour season finale of “Motive,” Flynn and Vega (Kristin Lehman, Louis Ferreira) identify a suspect in the death of an executive’s assistant, but there appears to be no motive. Um, so when does “Scandal” return?
“Age of Dinosaurs” (9 p.m., Syfy): Poor, poor Los Angeles. First, the city was pulverized by a brutal “Sharknado.” Now, it’s being invaded by prehistoric creatures in the cheese-fest “Age of Dinosaurs.” At least the Dodgers are having a good season.
