The Walker family returns for more dysfunctional family fun on Sunday, April 20, and ET was on the set as the cast and crew returned to work.

"It feels great to be back," SALLY FIELD, who plays Nora Walker, tells ET. "Great for me, great for the industry, great for the country and just generally great."

Sally spent her strike-induced time off with her grandkids and "worrying that everybody would be okay."

Her co-star, CALISTA FLOCKHART, who plays Nora's youngest daughter Kitty, did the mom thing, but she, too, is happy to be back: " It was a mixed blessing for me to have a little bit of a break, but I am very happy that we are all back and up and running."

While the ladies were pretty closed mouth about what we can expect from the hit ABC series, Calista did reveal that "Robert [ROB LOWE] and Kitty are trying to have a baby. Kitty really wants to have a baby and she is taking aggressive tactics to make that happen. I don't know if she is going to get pregnant or not."

She also reveals that Robert will still be in the middle of his presidential campaign. As fans know, he took the state of Michigan in the last episode that aired, and "he might end up becoming vice president," Calista shares.

The Walkers continue looking for love in all the wrong places -- and some of the right places -- and Nora is among them. Her relationship with Isaac (DANNY GLOVER) will continue, and while she won't say how serious they get on-screen, off-screen she says that "Danny is a great guy and a wonderful actor."

Tune in when "Brothers & Sisters" returns Sunday, April 20 at 10 p.m. on ABC.
