Weekend TV watch

Folks, we need to talk about Cersei. I’m worried about the Lannister facing trial on the season finale of

“Game of Thrones” (Sunday at 9 p.m. on HBO). Her plan to take down High Sparrow and the Faith Militant might involve burning King’s Landing to ash. Oh, and count on some charged moments with Littlefinger, Sansa, Tyrion and Daenerys.

Showtime gets you pumped for the debut of Cameron Crowe’s “Roadies” (Sunday at 10 p.m.) with the

documentary “Miles to Go Before I Sleep” (tonight at 8) from filmmaker Sam Jones. Musicians Chad Smith, Chris Shiflett and Jim James spill stories about bands and their road crews.

Was it murder or a mistake? “20/20” presents “Oscar Pistorius: The Killer

Speaks” (tonight at 10 on WCVB, Ch. 5) with the Blade Runner giving his version as to what happened the night he fatally shot his girlfriend Reeva Steenkamp.

“Black-ish” stars Anthony Anderson and Tracee Ellis Ross host the 16th annual

BET Awards (Sunday at 8 p.m. on BET). Usher, Future and Alicia Keys are among the musical guests, and Sheila E., the Roots and more will pay tribute to Prince in what will probably be the crowning moment of the night.

“Ray Donovan” (season premiere Sunday at 9 p.m. on Showtime) finds our Boston fixer once again drawn to a woman with scary issues. This time, it’s Lisa Bonet (“The Red Road”), guesting in an arc as a boxer’s sister. Ray, you should know better by now.
