The episode of Castle (9:01 p.m., ABC/Ch. 4) that was supposed to air this week has been flip-flopped with the episode that was scheduled for next week - because of what happened last week.ABC has decided to delay for a week an episode that features a plot about a bomb. From the description of that episode, it's absolutely nothing like the real events at the Boston Marathon last week, but I'm not going to criticize the network for being overly cautious.Instead, this is the episode we're getting tonight, with a description from ABC:"When Beckett is assigned to protect Erik Vaughn, a billionaire entrepreneur whose colleague was murdered, she can't help but be charmed by this dashing genius. Meanwhile, consumed with jealousy, Castle does everything he can to solve the case to get Vaughn out of Beckett's life."Over on the Sundance Channel, it's the two-hour premiere of Rectify at 10 p.m. This fascinating miniseries, which was screened at the Sundance Film Festival back in January, revolves around Daniel (Aden Young), a man released from prison after nearly 20 years on death row. He's a man out of time, a man trying to reconnect with his family, a man who may or may not be guilty of the horrific crime for which he was imprisoned.It's great stuff.Elsewhere on TV ...Dancing with the Stars (7 p.m., ABC/Ch. 4): The remaining contestants perform.The Voice (7 p.m., Ch. 5): The battle rounds continue.Bones (7 p.m., Fox/Ch. 13): A reporter is killed (what?!?!?) by a mutated virus.Brain Games (7, 9 and 11 p.m., National Geographnic Channel):Fun, fascinating new series that presents us with challenges and optical illusions and you will be fooled, I guarantee it.
