It's a slumber party for the big family of Walkers, in the next episode of "Brothers & Sisters". Also, just as Greenatopia gets the green light Sarah's business partner breaks some startling personal news and Nora rekindles a romance with an old flame, Roger (guest starring Nigel Havers). The episode called "It's Not Easy Being Green" will air January 18.

Meanwhile, the question on whether Balthazar Getty will exit from the show as Tommy Walker is still making rounds. Providing the latest hunch were Getty's co-stars, Matthew Rhys and Rachel Griffiths. Rhys aka Kevin Walker told E!, "I think the show is going through a slight transition period. How much we'll see him next season, I don't know." Griffiths aka Sarah meanwhile, said "We're a family. We'll get through it. And all I can say is we love him very dearly, and I'm seeing him on Monday, and I feel very good about that."

On other news, the show will bring back Jason Lewis to reprise his role as Kevin's ex, Chad. The character who left Kevin after coming out of the closet, will reportedly meet Kevin again at a bar in an episode airing April.
