* Survivor: Heroes vs. Villains (8/7c CBS)
Could Russell truly be the best player in Survivor history? After his reverse double-whammy blindside of Tyson and his ouster of Boston Rob - maybe. As de facto leader of the Villains, he is now poised to take his tribe to the end, but Coach is disillusioned and Jerri is flip-flopping...so maybe not. And in a first, the five remaining Heroes are using the immunity idol to unite rather than divide their tribe. Everyone's waiting for a merge. Mistakes are unacceptable, costly...and inevitable.
* The Masters (4/3c ESPN)
Augusta, Ga., becomes the centerpiece of spring, and guess who's the centerpiece of Augusta? Back on the links after a lengthy break, Tiger Woods' return is even bigger than the Masters itself this year. Moments when Woods is not on screen may include the tourney's official start, with Arnold Palmer and Jack Nicklaus whacking the ceremonial opener; and perhaps a hole or two with Ernie Els, who has won the last two PGA events he has entered.
Tonight marks the series' 100th episode, but that's not the only milestone worth mentioning as we dig deeper into the complex relationship between Brennan and Booth. It starts when Sweets thinks he's got them figured out for his new book, but he's astonished when he learns the truth about the first time they worked together. So cue the flashbacks to six years ago, chuckle at Zack and Hodgins' antics in the lab and check out the fireworks that could change your perception of the ongoing Brennan-Booth saga.
Another season of the hit dance contest comes to a close, but not before all nine crews return for one final group performance. Blueprint Cru and Poreotix are the two crews that remain in the running for the big prize. By the end of the night, one of them will walk away with the coveted title of America's Best Dance Crew and a cool $100,000 in cash, and the other crew will just walk away.
* FlashForward (8/7c ABC)
If you flash-forward six months, you may find an ABC without the high-octane drama on its schedule - and not because it's on hiatus. The show's been struggling to attract and retain viewers since returning from its three-and-a-half-month absence. This installment may not reverse that trend, but it should be fun nonetheless: Japanese import Keiko (Yuko Takeuchi), Bryce's girlfriend-to-be, job hunts in L.A. In more serious matters, Mark and Vogel set a trap to snare the FBI mole.
