10pm, FX
Justified
Raylan takes the fight to Avery and Walker in "The Trash and the Snake." Meanwhile, Boyd and Wynn are on the hunt for a safecracker, though their original plan to find one through Craigslist yielded the kind of email replies a person simply can't unsee.

10pm, BET
Being Mary Jane
In "Freedom," Mary Jane is determined to keep her weekend free from stress and shenanigans of every kind. But since that would make for an awfully boring hour of TV, Mark pops up needing her to play "beard" during a visit from his parents. Also disrupting Mary Jane's quiet time: her interview of a teen sex worker, which has her reconsidering her relationship with Niecy.

10pm, CBS
