“Game of Thrones” (9 p.m., HBO) and “The Killing” (8 p.m., AMC) both return tonight for their second seasons.

“Game of Thrones” is the kind of show you watch with lights off, curtains drawn and your cellphone stowed. Even the opening credits need to be watched, since they help provide information on the connections between the characters. This season starts where the last one left off: With King Robert dead and his psychopathic teenage son Joffrey on the throne, jockeying to become king intensifies. With so many players in this “Game,” you might want to keep a scorecard handy.

“The Killing,” a remake of a popular Danish show, “Forbrydelsen” (“The Crime”), asked last season: “Who killed Rosie Larsen?” … a question it never answered. The finale polarized viewers, many of whom had been expecting resolution. This season may reward fans who didn’t mind the bait-and-switch last season, and maybe a few former viewers who will overcome their frustration in their quest for closure. Then again, with this show, who knows if they’ll get it.


As “Bones” (8 p.m., Fox) returns, Brennan finally has her (and Booth’s) baby.


Are people still watching “One Tree Hill” (8 p.m., CW)? If you’re a fan, the series finale is Wednesday. If you’re not, this certainly isn’t the episode to start with.

As one show ends, another begins… Lennon Parkham and Jessica St. Clair star as “Best Friends Forever” (8:30 p.m., NBC). If you don’t want to wait, there’s a full-length preview.


Another new show starting this week is “Scandal” (10 p.m., ABC), starring Kerry Washington as a crisis manager. It’s from Shonda Rhimes, the creator of “Grey’s Anatomy.”


If you missed the premiere of  “Magic City” last Friday,  Starz repeats it today and tomorrow. It may be OK to get attached to this one: Even before it aired, Starz renewed it for a second season. Set at a luxury Miami Beach hotel circa 1959, “Magic City” stars Jeffrey Dean Morgan.
