Marion's rep tells me his client extricated herself from the role of Lily's grandmother when the part started being cut considerably. "It almost became a one-liner," says the rep. Instead, Marion is expected to appear in five more episodes of Brothers & Sisters this season as mom to Sally Field's Nora. Filling in for Marion will be St. Elsewhere vet Christina Pickles, who popped up last season on The CW's Privileged.
