Check out this new clip of “Downton Abbey’s” fourth season, which returns to the U.K. airwaves Sunday, Sept. 22 on ITV. In it, Lady Mary is quite somber and harsh — she’s obviously still grieving the death of Matthew and neither Anna nor her baby son can seem to lift her mood, which star Joanne Froggatt tells Zap2it is a hard situation for Anna because she so wants to help Mary.

“Lady Mary’s not really turning to anybody at this point,” says Froggatt. “She’s very much within her own grief. She won’t really express it with anyone. She’s locked in her grief and everyone’s trying to coax her back into the here and now.”

“Anna’s kind of walking a bit of a tightrope with Mary in the first episode because Anna can see that Mary needs to get back to the here and now for the sake of her son, but Anna’s in the position that she’s still her servant, so she can only say so much,” Froggatt continues. “It’s not her place to say, ‘C’mon, you’ve got a son to think of.’ That certainly is a concern for Anna in the first episode.”

How long do you think it will be before Lady Mary is her old self? “Downton Abbey” returns to the U.S. Jan. 5, 2014 on PBS.
