ABC's "Brothers & Sisters" - Season Four

BROTHERS & SISTERS - "Time After Time," Parts 1 & 2 - In an effort to get to the root of the secret that William's nemesis, Dennis York, holds over their heads, the Walkers recall their memories, both good and horrifying, of their family's days at Ojai Foods in 1986. Then, as they continue to flashback to their younger days, they finally recall the shocking secret and the shameful cover-up that led to York's power play, and are forced to deal with the remorse of a tragic event. Meanwhile, Nora and Holly take an uncharacteristic trip, a la "Thelma & Louise," to search for answers about Ojai's hidden worth, and Justin and Rebecca finally get their happily ever after, on a two-hour episode of "Brothers & Sisters," SUNDAY, APRIL 11 (9:00-11:00 p.m., ET), on the Disney General Entertainment Content via Getty Images Television Network.
